From ancient times when leather was used for practical purposes, to the modern fashion industry, where it is used for both functional and decorative purposes, leather has undergone significant changes in its production and usage. In recent years, there has been a growing awareness of ethical and sustainable fashion, leading to a shift towards alternative materials and production methods. The leather industry has responded to this by exploring new techniques and materials, such as vegetable-tanned leather and leather substitutes made from plant-based materials. The evolution of leather in the fashion industry is also closely tied to cultural and social trends. The use of leather has been associated with rebellion and counterculture in the past, and today it is often used to evoke a sense of luxury and sophistication. Despite the challenges and controversies surrounding its production, leather continues to be a popular material in the fashion industry, with designers and consumers alike valuing its durability, versatility, and aesthetic appeal. As fashion continues to evolve, so will the role and use of leather in the industry. This research paper provides a detailed overview of the evolution of leather in the fashion industry throughout the different decades and centuries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=evolution" title="evolution">evolution</a>, <a href="https://publications.waset.org/abstracts/search?q=fashion" title=" fashion"> fashion</a>, <a href="https://publications.waset.org/abstracts/search?q=leather" title=" leather"> leather</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable" title=" sustainable"> sustainable</a> </p> <a href="https://publications.waset.org/abstracts/169109/evolution-of-leather-in-fashion-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169109.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">93</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">68</span> Construct the Fur Input Mixed Model with Activity-Based Benefit Assessment Approach of Leather Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20F.%20Wu">M.

The fierce global competitive environment and common awareness of global carbon reduction make livestock supply quantities falling, salt and wet blue leather material reduces and the price skyrockets significantly. Exchange rate fluctuation led sales revenue decreasing which due to the differences of export exchanges and compresses the overall profitability of leather industry. This paper applies activity-based benefit assessment approach to build up fitness fur input mixed model, fur is Wet Blue, which concerned with four key factors: the output rate of wet blue, unit cost of wet blue, yield rate and grade level of Wet Blue to achieve the low cost strategy under given unit price of leather product condition of the company. The research findings indicate that applying this model may improve the input cost structure, decrease numbers of leather product inventories and to raise the competitive advantages of the enterprise in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activity-based%20benefit%20assessment%20approach" title="activity-based benefit assessment approach">activity-based benefit assessment approach</a>, <a href="https://publications.waset.org/abstracts/search?q=input%20mixed" title=" input mixed"> input mixed</a>, <a href="https://publications.waset.org/abstracts/search?q=output%20rate" title=" output rate"> output rate</a>, <a href="https://publications.waset.org/abstracts/search?q=wet%20blue" title=" wet blue"> wet blue</a> </p> <a href="https://publications.waset.org/abstracts/8567/construct-the-fur-input-mixed-model-with-activity-based-benefit-assessment-approach-of-leather-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8567.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">375</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">67</span> Revealing the Manufacturing Techniques of the Leather Scale Armour of Tutankhamun by the Assist of Conservation Procedures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Safwat%20Mohamed">Safwat Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasha%20Metawi"> Rasha Metawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadeel%20Khalil"> Hadeel Khalil</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussein%20Kamal"> Hussein Kamal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses and reveals the manufacturing techniques of the leather scale armour of Tutankhamun. This armour was in critical condition and went under many conservation procedures as it suffered from some serious deterioration aspects including fragmentation. In addition, its original shape was lost, the leather scales were found scattered in the box and separated from the linen basis, and hence its outlines were blurred and incomprehensible. In view of this, the leather scale armour of Tutankhamun was desperate for urgent conservation and reconstruction interventions. Documentation measures were done before conservation. Several re-treatable conservation procedures were applied seeking for stabilizing the armour and reaching sustainable condition. The conservation treatments included many investigations and analyses that helped in revealing materials and techniques of making the armour. The leather scale armour of Tutankhamun consisted of leather scales attached to a linen support. This linen support consisted of several layers. Howard Carter assumed that the linen support consisted of 6 layers. The undertaken conservation treatments helped in revealing the actual number of layers of the linen support as well as in reaching the most sustainable condition. This paper views the importance of the conservation procedures, which were recently carried out on Tutankhamun’s leather scale armour, in identifying and revealing all materials and techniques used in its manufacturing. The collected data about manufacturing techniques were used in making a replica of the leather scale armour with the same methods and materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leather%20scales%20armours" title="leather scales armours">leather scales armours</a>, <a href="https://publications.waset.org/abstracts/search?q=conservation" title=" conservation"> conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing%20techniques" title=" manufacturing techniques"> manufacturing techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=Tutankhamun" title=" Tutankhamun"> Tutankhamun</a>, <a href="https://publications.waset.org/abstracts/search?q=producing%20a%20replica" title=" producing a replica"> producing a replica</a> </p> <a href="https://publications.waset.org/abstracts/168377/revealing-the-manufacturing-techniques-of-the-leather-scale-armour-of-tutankhamun-by-the-assist-of-conservation-procedures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168377.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">101</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">66</span> Leather Quality of Some Sudan Goats under Range Condition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Alhadi%20Ebrahiem">Mohammed Alhadi Ebrahiem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was designed to investigate the effect of breed and feeding level before slaughter on the skin\leather quality of the three main breeds of Sudan goats.

These water-soluble dyes have a small organic molecular size. Besides the environmental hazards, these dyes cannot be underestimated, they also have harmful effects on human health. In this study, poly(hydroxyethyl methacrylate-glycidyl methacrylate) p(HEMA-GMA) hydrogel membranes were synthesized by UV polymerization method. The hydrogel synthesized is modified with imino diacetic acid (IDA) and then chelated with Cr (III) ions. The chelating capacity of the membranes was determined according to the time, pH and concentration parameters. Dynamic swelling test, elemental analysis, ninhydrin analysis and adsorption, desorption and reusability performances of membranes were also determined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=dye" title=" dye"> dye</a>, <a href="https://publications.waset.org/abstracts/search?q=leather" title=" leather"> leather</a>, <a href="https://publications.waset.org/abstracts/search?q=p%28HEMA-GMA%29-IDA" title=" p(HEMA-GMA)-IDA"> p(HEMA-GMA)-IDA</a> </p> <a href="https://publications.waset.org/abstracts/80973/characterization-of-polyhydroxyethyl-methacrylate-glycidyl-methacrylate-imino-diacetic-acid-membrane-to-adsorbing-leather-dye" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80973.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">182</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">64</span> The Pyrolysis of Leather and Textile Waste in Carbonised Materials as an Element of the Circular Economy Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maciej%20%C5%BBycki">Maciej Życki</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Kowalik-klimczak"> Anna Kowalik-klimczak</a>, <a href="https://publications.waset.org/abstracts/search?q=Monika%20%C5%81o%C5%BCy%C5%84ska"> Monika Łożyńska</a>, <a href="https://publications.waset.org/abstracts/search?q=Wioletta%20Barszcz"> Wioletta Barszcz</a>, <a href="https://publications.waset.org/abstracts/search?q=Jolanta%20Drabik%20Anna%20Kowalik-klimczak"> Jolanta Drabik Anna Kowalik-klimczak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The rapidly changing fashion trends generate huge amounts of leather and textile waste globally. The complexity of these types of waste makes recycling difficult in economic terms. Pyrolysis is suggested for this purpose, which transforms heterogeneous and complex waste into added-value products e.g. active carbons and soil fertilizer. The possibility of using pyrolysis for the valorization of leather and textile waste has been analyzed in this paper. In the first stage, leather and textile waste were subjected to TG/DTG thermogravimetric and DSC calorimetric analysis. These analyses provided basic information about thermochemical transformations and degradation rates during the pyrolysis of these types of waste and enabled the selection of the pyrolysis temperature. In the next stage, the effect of gas type using pyrolysis was investigated on the physicochemical properties, composition, structure, and formation of the specific surfaces of carbonized materials produced by means of a thermal treatment without oxygen access to the reaction chamber. These studies contribute some data about the thermal management and pyrolytic processing of leather and textile waste into useful carbonized materials, according to the circular economy model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pyrolysis" title="pyrolysis">pyrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=leather%20and%20textiles%20waste" title=" leather and textiles waste"> leather and textiles waste</a>, <a href="https://publications.waset.org/abstracts/search?q=composition%20and%20structure%20of%20carbonized%20materials" title=" composition and structure of carbonized materials"> composition and structure of carbonized materials</a>, <a href="https://publications.waset.org/abstracts/search?q=valorisation%20of%20waste" title=" valorisation of waste"> valorisation of waste</a>, <a href="https://publications.waset.org/abstracts/search?q=circular%20economy%20model" title=" circular economy model"> circular economy model</a> </p> <a href="https://publications.waset.org/abstracts/194644/the-pyrolysis-of-leather-and-textile-waste-in-carbonised-materials-as-an-element-of-the-circular-economy-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194644.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">8</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">63</span> Antecedent and Outcome of New Product Development in Leather Industry, Bangkok and Vicinity, Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bundit%20Pungnirund">Bundit Pungnirund</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purposes of this research were to develop and to monitor the antecedent factors which directly affected the success rate of new product development.

Hot wire machining can cut the leather in the required shape by controlling the wire by generating thermal energy. In the present study, an attempt has been made to investigate the effects of performance measures in the hot wire machining process on cutting leather specimens. Carbonization and material removal rates were considered as quality indicators. Burning leather during machining might cause carbon particles, reducing product quality. Minimizing the effect of carbon particles is crucial for assuring operator and environmental safety, health, and product quality. Hot wire machining can efficiently cut the specimens by controlling the current through it. Taguchi- DEAR-based optimization was also performed in the process, which resulted in a required Carbonization and material removal rate. Using the DEAR approach, the optimal parameters of the present study were found with 3.7% prediction error accuracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cabronization" title="cabronization">cabronization</a>, <a href="https://publications.waset.org/abstracts/search?q=leather" title=" leather"> leather</a>, <a href="https://publications.waset.org/abstracts/search?q=MRR" title=" MRR"> MRR</a>, <a href="https://publications.waset.org/abstracts/search?q=current" title=" current"> current</a> </p> <a href="https://publications.waset.org/abstracts/178081/performance-evaluation-and-dear-based-optimization-on-machining-leather-specimens-to-reduce-carbonization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178081.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">64</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">61</span> Treatment of Leather Industry Wastewater with Advance Treatment Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seval%20Yilmaz">Seval Yilmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Filiz%20Bayrakci%20Karel"> Filiz Bayrakci Karel</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Savas%20Koparal"> Ali Savas Koparal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Textile products produced by leather have been indispensable for human consumption. Various chemicals are used to enhance the durability of end-products in the processing of leather products. The wastewaters from the leather industry which contain these chemicals exhibit toxic effects on the receiving environment and threaten the natural ecosystem. In this study, leather industry wastewater (LIW), which has high loads of contaminants, was treated using advanced treatment techniques instead of conventional methods. During the experiments, the performance of electrochemical methods was investigated. During the electrochemical experiments, the performance of batch electrooxidation (EO) using boron-doped diamond (BDD) electrodes with monopolar configuration for removal of chemical oxygen demand (COD) from LIW were investigated. The influences of electrolysis time, current density (which varies as 5 mA/cm², 10 mA/cm², 20 mA/cm², 30 mA/cm², 50 mA/cm²) and initial pH (which varies as 3,80 (natural pH of LIW), 7, 9) on removal efficiency were investigated in a batch stirred cell to determine the best treatment conditions. The current density applied to the electrochemical reactors is directly proportional to the consumption of electric energy, so electrical energy consumption was monitored during the experiment. The best experimental conditions obtained in electrochemical studies were as follows: electrolysis time = 60 min, current density = 30.0 mA/cm², pH 7. Using these parameters, 53.59% COD removal rates for LIW was achieved and total energy consumption was obtained as 13.03 kWh/m³. It is concluded that electrooxidation process constitutes a plausible and developable method for the treatment of LIW. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BDD%20electrodes" title="BDD electrodes">BDD electrodes</a>, <a href="https://publications.waset.org/abstracts/search?q=COD%20removal" title=" COD removal"> COD removal</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20treatment" title=" electrochemical treatment"> electrochemical treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=leather%20industry%20wastewater" title=" leather industry wastewater"> leather industry wastewater</a> </p> <a href="https://publications.waset.org/abstracts/96331/treatment-of-leather-industry-wastewater-with-advance-treatment-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96331.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> Designing Function Knitted and Woven Upholstery Textile With SCOPY Film</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manar%20Y.%20Abd%20El-Aziz">Manar Y.

However, upholstery parts may become unhealthy when dust accrues and bacteria raise on the surface, which negatively affects the user's health. Also, leather and artificial leather were used in upholstery but, leather has a high cost and artificial leather has a potential chemical risk for users. Researchers have advanced vegie leather made from bacterial cellulose a symbiotic culture of bacteria and yeast (SCOBY). SCOBY remains a gelatinous, cellulose biofilm discovered floating at the air-liquid interface of the container. But this leather still needs some enhancement for its mechanical properties. This study aimed to prepare SCOBY, produce bamboo rib knitted fabrics with two different stitch densities, and cotton woven fabric then laminate these fabrics with the prepared SCOBY film to enhance the mechanical properties of the SCOBY leather at the same time; add anti-microbial function to the prepared fabrics. Laboratory tests were conducted on the produced samples, including tests for function properties; anti-microbial, thermal conductivity and light transparency. Physical properties; thickness and mass per unit. Mechanical properties; elongation, tensile strength, young modulus, and peel force. The results showed that the type of the fabric affected significantly SCOBY properties. According to the test results, the bamboo knitted fabric with higher stitch density laminated with SCOBY was chosen for its tensile strength and elongation as the upholstery of a bed model with antimicrobial properties and comfortability in the headrest design. Also, the single layer of SCOBY was chosen regarding light transparency and lower thermal conductivity for the creation of a lighting unit built into the bed headboard. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-microbial" title="anti-microbial">anti-microbial</a>, <a href="https://publications.waset.org/abstracts/search?q=bamboo" title=" bamboo"> bamboo</a>, <a href="https://publications.waset.org/abstracts/search?q=rib" title=" rib"> rib</a>, <a href="https://publications.waset.org/abstracts/search?q=SCOPY" title=" SCOPY"> SCOPY</a>, <a href="https://publications.waset.org/abstracts/search?q=upholstery" title=" upholstery"> upholstery</a> </p> <a href="https://publications.waset.org/abstracts/173473/designing-function-knitted-and-woven-upholstery-textile-with-scopy-film" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173473.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">64</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59</span> The Effect of Market Orientation on Marketing Performance through Product Adaptation Strategy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hotlan%20Siagian">Hotlan Siagian</a>, <a href="https://publications.waset.org/abstracts/search?q=Hatane%20Semuel"> Hatane Semuel</a>, <a href="https://publications.waset.org/abstracts/search?q=Wilma%20Laura%20Sahetapy"> Wilma Laura Sahetapy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims at examining the effect of market orientation on marketing performance through product adaptation strategy.

Accurate cost information is a great help for managers in dealing with operation strategies. This paper establishes a profitability management mechanism that applies the Activity-Based Benefit approach (ABBA) to solve the profitability for each customer from the market. ABBA provides financial and non-financial information for the operation, but also indicates what resources have expired in the operational process. The customer profit management model shows the level of profitability of each customer for the company. The empirical data were gathered from a case company operating in the leather industry in Taiwan. The research findings indicate that 30% of customers create little profit for the company as a result of asking for over 5% of sales discounts. Those customers ask for sales discount because of color differences of leather products. This paper provides a customer’s profitability evaluation mechanism to help enterprises to greatly improve operating effectiveness and promote operational activity efficiency and overall operation profitability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activity-based%20benefit%20approach" title="activity-based benefit approach">activity-based benefit approach</a>, <a href="https://publications.waset.org/abstracts/search?q=customer%20profit%20analysis" title=" customer profit analysis"> customer profit analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=leather%20industry" title=" leather industry"> leather industry</a>, <a href="https://publications.waset.org/abstracts/search?q=profitability%20management%20mechanism" title=" profitability management mechanism"> profitability management mechanism</a> </p> <a href="https://publications.waset.org/abstracts/61548/the-profitability-management-mechanism-of-leather-industry-based-on-the-activity-based-benefit-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61548.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">307</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">57</span> Conducting Glove Leathers Prepared through in-situ Polymerization of Pyrrole</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wegene%20Demisie%20Jima">Wegene Demisie Jima</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Leather is a durable and flexible material used for various purposes including clothing, footwear, upholstery and gloves. However, the use of leather for smart product applications is a challenge since it is electrically insulating material. Here, we report a simple method to produce conducting glove leathers using an in-situ polymerization of pyrrole. The concentrations of pyrrole, ferric chloride and anthraquinone-2-sulfonic acid sodium salt monohydrate were optimized to produce maximum conductivity in the treated leathers. The coating of polypyrrole in the treated leathers was probed using FT-IR, X-ray diffraction and electron microscopic analysis. FTIR confirms that the formation of polypyrrole on the leather surface as well as presence of prominent N-C stretching band. X-ray diffraction analysis suggests para-crystallinity in the PPy-treated leathers.We further demonstrate that the treated leathers, with maximum conductivity of 7.4 S/cm, can be used for making conductive gloves for operating touch-screen devices apart from other smart product applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrical%20conductivity" title="electrical conductivity">electrical conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=in-situ%20polymerization" title=" in-situ polymerization"> in-situ polymerization</a>, <a href="https://publications.waset.org/abstracts/search?q=pyrrole" title=" pyrrole"> pyrrole</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20product" title=" smart product"> smart product</a> </p> <a href="https://publications.waset.org/abstracts/84514/conducting-glove-leathers-prepared-through-in-situ-polymerization-of-pyrrole" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84514.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">194</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> Valorization of Waste and By-products for Protein Extraction and Functional Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lorena%20Coelho">Lorena Coelho</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Ramada"> David Ramada</a>, <a href="https://publications.waset.org/abstracts/search?q=Catarina%20Nobre"> Catarina Nobre</a>, <a href="https://publications.waset.org/abstracts/search?q=Joaquim%20Gai%C3%A3o"> Joaquim Gaião</a>, <a href="https://publications.waset.org/abstracts/search?q=Juliana%20Duarte"> Juliana Duarte</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of processes that allows the valorization of waste and by-products generated by industries is crucial to promote symbiotic relationships between different sectors and is mandatory to “close the loop” in the circular economy paradigm. In recent years, by-products and waste from agro-food and forestry sector have attracted attention due to their potential application and technical characteristics. The extraction of bio-based active compounds to be reused is in line with the circular bioeconomy concept trends, combining the use of renewable resources with the process’s circularity, aiming the waste reduction and encouraging reuse and recycling. Among different types of bio-based materials, which are being explored and can be extracted, proteins fractions are becoming an attractive new raw material. Within this context, BioTrace4Leather project, a collaboration between two Technological Centres – CeNTI and CTIC, and a company of Tanning and Finishing of Leather – Curtumes Aveneda, aims to develop innovative and biologically sustainable solutions for leather industry and accomplish the market circularity trends. Specifically, it aims to the valorisation of waste and by-products from the tannery industry through proteins extraction and the development of an innovative and biologically sustainable materials. The achieved results show that keratin, gelatine, and collagen fractions can be successfully extracted from hair and leather bovine waste. These products could be reintegrated into the industrial manufacturing process to attain innovative and functional textile and leather substrates.

BDSM-inspired fashion can be seen in various forms, from leather harnesses and corsets to studded collars and latex clothing. BDSM fashion is often associated with edginess, rebellion, and sexuality. It has been embraced by subcultures such as punk, Goth, and fetish, as well as mainstream fashion designers looking to push boundaries and make a statement. However, the use of BDSM imagery in fashion has also been criticized for promoting objectification, exploitation, and the normalization of abusive behavior. Some argue that the fashion industry's depiction of BDSM often reinforces harmful stereotypes and misconceptions about the practice. Despite the controversy, BDSM-inspired fashion continues to have a place in the industry, with designers and consumers alike finding value in its aesthetic appeal and provocative nature. As with any aspect of fashion, the role of BDSM in the industry will continue to evolve and adapt to changing cultural norms and societal attitudes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BDSM" title="BDSM">BDSM</a>, <a href="https://publications.waset.org/abstracts/search?q=leather" title=" leather"> leather</a>, <a href="https://publications.waset.org/abstracts/search?q=fashion" title=" fashion"> fashion</a>, <a href="https://publications.waset.org/abstracts/search?q=lycra" title=" lycra"> lycra</a> </p> <a href="https://publications.waset.org/abstracts/170139/influence-of-bondage-discipline-sadism-masochism-bdsm-on-fashion-industry-on-fashion-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170139.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> Industrial Waste to Energy Technology: Engineering Biowaste as High Potential Anode Electrode for Application in Lithium-Ion Batteries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pejman%20Salimi">Pejman Salimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastiano%20Tieuli"> Sebastiano Tieuli</a>, <a href="https://publications.waset.org/abstracts/search?q=Somayeh%20Taghavi"> Somayeh Taghavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Michela%20Signoretto"> Michela Signoretto</a>, <a href="https://publications.waset.org/abstracts/search?q=Remo%20Proietti%20Zaccaria"> Remo Proietti Zaccaria</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Increasing the growth of industrial waste due to the large quantities of production leads to numerous environmental and economic challenges, such as climate change, soil and water contamination, human disease, etc. Energy recovery of waste can be applied to produce heat or electricity. This strategy allows for the reduction of energy produced using coal or other fuels and directly reduces greenhouse gas emissions. Among different factories, leather manufacturing plays a very important role in the whole world from the socio-economic point of view. The leather industry plays a very important role in our society from a socio-economic point of view. Even though the leather industry uses a by-product from the meat industry as raw material, it is considered as an activity demanding integrated prevention and control of pollution. Along the entire process from raw skins/hides to finished leather, a huge amount of solid and water waste is generated. Solid wastes include fleshings, raw trimmings, shavings, buffing dust, etc. One of the most abundant solid wastes generated throughout leather tanning is shaving waste. Leather shaving is a mechanical process that aims at reducing the tanned skin to a specific thickness before tanning and finishing. This product consists mainly of collagen and tanning agent. At present, most of the world's leather processing is chrome-tanned based. Consequently, large amounts of chromium-containing shaving wastes need to be treated. The major concern about the management of this kind of solid waste is ascribed to chrome content, which makes the conventional disposal methods, such as landfilling and incineration, not practicable. Therefore, many efforts have been developed in recent decades to promote eco-friendly/alternative leather production and more effective waste management. Herein, shaving waste resulting from metal-free tanning technology is proposed as low-cost precursors for the preparation of carbon material as anodes for lithium-ion batteries (LIBs). In line with the philosophy of a reduced environmental impact, for preparing fully sustainable and environmentally friendly LIBs anodes, deionized water and carboxymethyl cellulose (CMC) have been used as alternatives to toxic/teratogen N-methyl-2- pyrrolidone (NMP) and to biologically hazardous Polyvinylidene fluoride (PVdF), respectively. Furthermore, going towards the reduced cost, we employed water solvent and fluoride-free bio-derived CMC binder (as an alternative to NMP and PVdF, respectively) together with LiFePO₄ (LFP) when a full cell was considered. These actions make closer to the 2030 goal of having green LIBs at 100 $ kW h⁻¹. Besides, the preparation of the water-based electrodes does not need a controlled environment and due to the higher vapour pressure of water in comparison with NMP, the water-based electrode drying is much faster. This aspect determines an important consequence, namely a reduced energy consumption for the electrode preparation. The electrode derived from leather waste demonstrated a discharge capacity of 735 mAh g⁻¹ after 1000 charge and discharge cycles at 0.5 A g⁻¹. This promising performance is ascribed to the synergistic effect of defects, interlayer spacing, heteroatoms-doped (N, O, and S), high specific surface area, and hierarchical micro/mesopore structure of the biochar. Interestingly, these features of activated biochars derived from the leather industry open the way for possible applications in other EESDs as well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biowaste" title="biowaste">biowaste</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20batteries" title=" lithium-ion batteries"> lithium-ion batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20activation" title=" physical activation"> physical activation</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20management" title=" waste management"> waste management</a>, <a href="https://publications.waset.org/abstracts/search?q=leather%20industry" title=" leather industry"> leather industry</a> </p> <a href="https://publications.waset.org/abstracts/142244/industrial-waste-to-energy-technology-engineering-biowaste-as-high-potential-anode-electrode-for-application-in-lithium-ion-batteries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142244.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">171</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> A Study of Binding Methods and Techniques in Safavid Era Emphasizing on Iran Shahnamehs (16-18th Century AD/10-12th Century AH)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashrafosadat%20Mousavi%20Laer">Ashrafosadat Mousavi Laer</a>, <a href="https://publications.waset.org/abstracts/search?q=Elaheh%20Moravej"> Elaheh Moravej</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The art of binding was simple and elementary at the beginning of Islam. This art thrived gradually and continued its development as an independent art. Identification of the binding techniques and used materials in covers and investigation of the arrays give us indexes for the better identification of different doctrines and methods of that time. The catalogers of the manuscripts usually pay attention to four items: gender, color, art elegances, injury, and exquisiteness of the cover. The criterion for classification of the covers is their art nature and gender. 15th century AD (9th century AH) was the period of the binding art development in which the most beautiful covers were produced by the so-called method of ‘burning’. At 16th century AD (10th century AH), in Safavid era, art changed completely and a fundamental evolution occurred in the technique and method of binding. The greatest change in this art was the extensive use of stamp that was made mostly of steel and copper. Theses stamps were presses against leather. These covers were called ‘beat’. In this paper, writing and bookbinding of about 32 Shahnamehs of Safavid era available in the Iranian libraries and museums are studied. An analytical-statistical study shows that four methods have been used including beat, burning, mosaic, and oily. 69 percent of the covers of these copies are cardboards with a leathery coating (goatskin) and have been produced by burning and beat methods. Its reasons are that these two methods have been common methods in Safavid era and performing them was only feasible on leather and the most desirable and commonly used leather of that time was goatskin which was the best option for cover legend durability and preserving the book and it was more durable because it had been made of goat skin. In addition, it had prepared a suitable opportunity for the binding artist’s creativity and innovation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shahnameh" title="Shahnameh">Shahnameh</a>, <a href="https://publications.waset.org/abstracts/search?q=Safavid%20era" title=" Safavid era"> Safavid era</a>, <a href="https://publications.waset.org/abstracts/search?q=bookbinding" title=" bookbinding"> bookbinding</a>, <a href="https://publications.waset.org/abstracts/search?q=beat%20cover" title=" beat cover"> beat cover</a>, <a href="https://publications.waset.org/abstracts/search?q=burning%20cover" title=" burning cover"> burning cover</a> </p> <a href="https://publications.waset.org/abstracts/34892/a-study-of-binding-methods-and-techniques-in-safavid-era-emphasizing-on-iran-shahnamehs-16-18th-century-ad10-12th-century-ah" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34892.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">238</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> In Vitro Assessment of the Genotoxicity of Composite Obtained by Mixture of Natural Rubber and Leather Residues for Textile Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dalita%20G.%20S.%20M.%20Cavalcante">Dalita G.

Job </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to minimize environmental impacts, a composite was developed from mixture of leather shavings (LE) with natural rubber (NR), which patent is already deposited. The new material created can be used in applications such as floors e heels for shoes. Besides these applications, the aim is to use this new material for the production of products for the textile industry, such as boots, gloves and bags. But the question arises, as to biocompatibility of this new material. This is justified because the structure of the leather shavings has chrome. The trivalent chromium is usually not toxic, but the hexavalent chromium can be highly toxic and genotoxic for living beings, causing damage to the DNA molecule and contributing to the formation of cancer. Based on this, the objective of this study is evaluate the possible genotoxic effects of the new composite, using as system - test two cell lines (MRC-5 and CHO-K1) by comet assay. For this, the production of the composite was performed in three proportions: for every 100 grams of NR was added 40 (E40), 50 (E50) or 60 (E60) grams of LE. The latex was collected from the rubber tree (Hevea brasiliensis). For vulcanization of the NR, activators and accelerators were used. The two cell lines were exposed to the new composite in its three proportions using elution method, that is, cells exposed to liquid extracts obtained from the composite for 24 hours. For obtaining the liquid extract, each sample of the composite was crushed into pieces and mixed with an extraction solution. The quantification of total chromium and hexavalent chromium in the extracts were performed by Optical Emission Spectrometry by Inductively Coupled Plasma (ICP-OES). The levels of DNA damage in cells exposed to both extracts were monitored by alkaline version of the comet assay. The results of the quantification of metals in ICP-OES indicated the presence of total chromium in different extracts, but were not detected presence of hexavalent chromium in any extract. Through the comet assay were not found DNA damage of the CHO-K1 cells exposed to both extracts. As for MRC-5, was found a significant increase in DNA damage in cells exposed to E50 and E60. Based on the above data, it can be asserted that the extracts obtained from the composite were highly genotoxic for MRC-5 cells. These biological responses do not appear to be related to chromium metal, since there was a predominance of trivalent chromium in the extracts, indicating that during the production process of the new composite, there was no formation of hexavalent chromium. In conclusion it can infer that the leather shavings containing chromium can be reused, thereby reducing the environmental impacts of this waste. Already on the composite indicates to its incorporation in applications that do not aim at direct contact with the human skin, and it is suggested the chain of composite production be studied, in an attempt to make it biocompatible so that it may be safely used by the textile industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cell%20line" title="cell line">cell line</a>, <a href="https://publications.waset.org/abstracts/search?q=chrome" title=" chrome"> chrome</a>, <a href="https://publications.waset.org/abstracts/search?q=genotoxicity" title=" genotoxicity"> genotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=leather" title=" leather"> leather</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20rubber" title=" natural rubber"> natural rubber</a> </p> <a href="https://publications.waset.org/abstracts/39981/in-vitro-assessment-of-the-genotoxicity-of-composite-obtained-by-mixture-of-natural-rubber-and-leather-residues-for-textile-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39981.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">197</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> Mental Well-Being and Quality of Life: A Comparative Study of Male Leather Tannery and Non-Tannery Workers of Kanpur City, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gyan%20Kashyap">Gyan Kashyap</a>, <a href="https://publications.waset.org/abstracts/search?q=Shri%20Kant%20Singh"> Shri Kant Singh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Improved mental health can be articulated as a good physical health and quality of life. Mental health plays an important role in survival of any one’s life. In today’s time people living with stress in life due to their personal matters, health problems, unemployment, work environment, living environment, substance use, life style and many more important reasons. Many studies confirmed that the significant proportion of mental health people increasing in India. This study is focused on mental well-being of male leather tannery workers in Kanpur city, India. Environment at work place as well as living environment plays an important health risk factors among leather tannery workers. Leather tannery workers are more susceptible to many chemicals and physical hazards, just because they are liable to be affected by their exposure to lots of hazardous materials and processes during tanning work in very hazardous work environment. The aim of this study to determine the level of mental health disorder and quality of life among male leather tannery and non-tannery workers in Kanpur city, India. This study utilized the primary data from the cross- sectional household study which was conducted from January to June, 2015 on tannery and non-tannery workers as a part of PhD program from the Jajmau area of Kanpur city, India. The sample of 286 tannery and 295 non-tannery workers has been collected from the study area. We have collected information from the workers of age group 15-70 those who were working at the time of survey for at least one year. This study utilized the general health questionnaire (GHQ-12) and work related stress scale to test the mental wellbeing of male tannery and non-tannery workers. By using GHQ-12 and work related stress scale, Polychoric factor analysis method has been used for best threshold and scoring. Some of important question like ‘How would you rate your overall quality of life’ on Likert scale to measure the quality of life, their earnings, education, family size, living condition, household assets, media exposure, health expenditure, treatment seeking behavior and food habits etc. Results from the study revealed that around one third of tannery workers had severe mental health problems then non-tannery workers. Mental health problem shown the statistically significant association with wealth quintile, 56 percent tannery workers had severe mental health problem those belong to medium wealth quintile. And 42 percent tannery workers had moderate mental health problem among those from the low wealth quintile. Work related stress scale found the statistically significant results for tannery workers. Large proportion of tannery and non-tannery workers reported they are unable to meet their basic needs from their earnings and living in worst condition. Important result from the study, tannery workers who were involved in beam house work in tannery (58%) had severe mental health problem. This study found the statistically significant association with tannery work and mental health problem among tannery workers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GHQ-12" title="GHQ-12">GHQ-12</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20well-being" title=" mental well-being"> mental well-being</a>, <a href="https://publications.waset.org/abstracts/search?q=factor%20analysis" title=" factor analysis"> factor analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=tannery%20workers" title=" tannery workers "> tannery workers </a> </p> <a href="https://publications.waset.org/abstracts/40666/mental-well-being-and-quality-of-life-a-comparative-study-of-male-leather-tannery-and-non-tannery-workers-of-kanpur-city-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40666.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">387</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Skill-Based or Necessity-Driven Entrepreneurship in Animal Agriculture for Sustainable Job and Wealth Creations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20S.%20R.%20Butswat">I.

AA is an integral segment of the world food industry, and provides a good and rapid source of income. The contribution of AA to the Sub-Saharan economy is quite significant, and there are still large opportunities that remain untapped in the sector. However, it is imperative to understand, simplify and package the various components of AA in order to pave way for rapid wealth creation, poverty eradication and women empowerment programmes in sub-Saharan Africa and other developing countries. The entrepreneurial areas of AA highlighted were animal breeding, livestock fattening, dairy production, poultry farming, meat production (beef, mutton, chevon, etc.), rabbit farming, wool/leather production, animal traction, animal feed industry, commercial pasture management, fish farming, sport animals, micro livestock production, private ownership of abattoirs, slaughter slabs, animal parks and zoos, among others. This study concludes that reproductive biotechnology such as oestrous synchronization, super-/multiple ovulation, artificial insemination and embryo transfer can be employed as a tool for improvement of genetic make-up of low-yielding animals in terms of milk, meat, egg, wool, leather production and other economic traits that will necessitate sustainable job and wealth creations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=animal" title="animal">animal</a>, <a href="https://publications.waset.org/abstracts/search?q=agriculture" title=" agriculture"> agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=entreprenurship" title=" entreprenurship"> entreprenurship</a>, <a href="https://publications.waset.org/abstracts/search?q=wealth" title=" wealth"> wealth</a> </p> <a href="https://publications.waset.org/abstracts/79982/skill-based-or-necessity-driven-entrepreneurship-in-animal-agriculture-for-sustainable-job-and-wealth-creations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79982.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">248</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> The Socio-Economic Impact of the English Leather Glove Industry from the 17th Century to Its Recent Decline</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frances%20Turner">Frances Turner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gloves are significant physical objects, being one of the oldest forms of dress. Glove culture is part of every facet of life; its extraordinary history encompasses practicality, and symbolism reflecting a wide range of social practices. The survival of not only the gloves but associated articles enables the possibility to analyse real lives, however so far this area has been largely neglected. Limited information is available to students, researchers, or those involved with the design and making of gloves. There are several museums and independent collectors in England that hold collections of gloves (some from as early as 16th century), machinery, tools, designs and patterns, marketing materials and significant archives which demonstrate the rich heritage of English glove design and manufacturing, being of national significance and worthy of international interest. Through a research glove network which now exists thanks to research grant funding, there is potential for the holders of glove collections to make connections and explore links between these resources to promote a stronger understanding of the significance, breadth and heritage of the English glove industry. The network takes an interdisciplinary approach to bring together interested parties from academia, museums and manufacturing, with expert knowledge of the production, collections, conservation and display of English leather gloves. Academics from diverse arts and humanities disciplines benefit from the opportunities to share research and discuss ideas with network members from non-academic contexts including museums and heritage organisations, industry, and contemporary designers. The fragmented collections when considered in entirety provide an overview of English glove making since earliest times and those who wore them. This paper makes connections and explores links between these resources to promote a stronger understanding of the significance, breadth and heritage of the English Glove industry. The following areas are explored: current content and status of the individual museum collections, potential links, sharing of information histories, social and cultural and relationship to history of fashion design, manufacturing and materials, approaches to maintenance and conservation, access to the collections and strategies for future understanding of their national significance. The facilitation of knowledge exchange and exploration of the collections through the network informs organisations’ future strategies for the maintenance, access and conservation of their collections. By involving industry in the network, it is possible to ensure a contemporary perspective on glove-making in addition to the input from heritage partners. The slow fashion movement and awareness of artisan craft and how these can be preserved and adopted for glove and accessory design is addressed. Artisan leather glove making was a skilled and significant industry in England that has now declined to the point where there is little production remaining utilising the specialist skills that have hardly changed since earliest times. This heritage will be identified and preserved for future generations of the rich cultural history of gloves may be lost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artisan%20glove-making%20skills" title="artisan glove-making skills">artisan glove-making skills</a>, <a href="https://publications.waset.org/abstracts/search?q=English%20leather%20gloves" title=" English leather gloves"> English leather gloves</a>, <a href="https://publications.waset.org/abstracts/search?q=glove%20culture" title=" glove culture"> glove culture</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20glove%20network" title=" the glove network "> the glove network </a> </p> <a href="https://publications.waset.org/abstracts/120910/the-socio-economic-impact-of-the-english-leather-glove-industry-from-the-17th-century-to-its-recent-decline" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120910.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">129</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">47</span> Design and Implementation of Smart Watch Textile Antenna for Wi-Fi Bio-Medical Applications in Millimetric Wave Band</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20G.%20Ghanem">M.

The antenna is implemented on a leather textile-based substrate to be embedded in a smartwatch. It enables the watch to pick Wi-Fi signals without the need to be connected to a mobile through Bluetooth. It operates at 60 GHz or WiGig (Wireless Gigabit Alliance) band with a wide band for higher rate applications. It also could be implemented over many stratified layers of the body organisms to be used in the diagnosis of many diseases like diabetes and cancer. The structure is designed and simulated using CST (Studio Suite) program. The wearable patch antenna has an octagon shape, and it is implemented on leather material that acts as a flexible substrate with a size of 5.632 x 6.4 x 2 mm3, a relative permittivity of 2.95, and a loss tangent of 0.006. The feeding is carried out using differential feed (discrete port in CST). The work provides five antenna implementations; antenna without ground, a ground is added at the back of the antenna in order to increase the antenna gain, the substrate dimensions are increased to 15 x 30 mm2 to resemble the real hand watch size, layers of skin and fat are added under the ground of the antenna to study the effect of human body tissues human on the antenna performance. Finally, the whole structure is bent. It is found that the antenna can achieve a simulated peak realized gain in dB of 5.68, 7.28, 6.15, 3.03, and 4.37 for antenna without ground, antenna with the ground, antenna with larger substrate dimensions, antenna with skin and fat, and bent structure, respectively. The antenna with ground exhibits high gain; while adding the human organisms absorption, the gain is degraded because of human absorption. The bent structure contributes to higher gain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio%20medical%20engineering" title="bio medical engineering">bio medical engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=millimetric%20wave" title=" millimetric wave"> millimetric wave</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20watch" title=" smart watch"> smart watch</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20antennas" title=" textile antennas"> textile antennas</a>, <a href="https://publications.waset.org/abstracts/search?q=Wi-Fi" title=" Wi-Fi"> Wi-Fi</a> </p> <a href="https://publications.waset.org/abstracts/151586/design-and-implementation-of-smart-watch-textile-antenna-for-wi-fi-bio-medical-applications-in-millimetric-wave-band" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151586.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">121</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Removal of Protein from Chromium Tanning Bath by Biological Treatment Using Pseudomonas sp.</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amel%20Benhadji">Amel Benhadji</a>, <a href="https://publications.waset.org/abstracts/search?q=Mourad%20Taleb%20Ahmed"> Mourad Taleb Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachida%20Maachi"> Rachida Maachi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The challenge for the new millennium is to develop an industrial system that has minimal socio-ecological impacts, without compromising quality of life.

Due to their chemical structures, dyes are resistant to fading on exposure to light, water and many chemicals and, therefore, are difficult to be decolorized once released into the aquatic environment. Many of the organic dyes are hazardous and may affect aquatic life and even the food chain. This study deals with the adsorption of malachite green dye onto fly ash and red mud. The effects of experimental factors (adsorbent dosage, initial concentration, pH and temperature) on the adsorption process were examined by using 24 full factorial design. The results were statistically analyzed by using the student’s t-test, analysis of variance (ANOVA) and an F-test to define important experimental factors and their levels. A regression model that considers the significant main and interaction effects was suggested. The results showed that initial dye concentration an pH is the most significant factor that affects the removal of malachite green. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=malachite%20green" title="malachite green">malachite green</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=red%20mud" title=" red mud"> red mud</a>, <a href="https://publications.waset.org/abstracts/search?q=fly%20ash" title=" fly ash"> fly ash</a>, <a href="https://publications.waset.org/abstracts/search?q=full%20factorial%20design" title=" full factorial design"> full factorial design</a> </p> <a href="https://publications.waset.org/abstracts/21950/adsorption-of-malachite-green-dye-onto-industrial-waste-materials-full-factorial-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21950.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">476</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Optimization of Effecting Parameters for the Removal of H₂S Gas in Self Priming Venturi Scrubber Using Response Surface Methodology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manisha%20Bal">Manisha Bal</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20C.%20Meikap"> B.

Abatement of H₂S gas from the air is very necessary. H₂S gas is mainly released from the industries like paper and leather industry as well as during the production of crude oil, during wastewater treatment, etc. But the emission of H₂S gas in high concentration may cause immediate death while at lower concentrations can cause various respiratory problems. In the present study, self priming venturi scrubber is used to remove the H₂S gas from the air. Response surface methodology with central composite design has been chosen to observe the effect of process parameters on the removal efficiency of H₂S. Experiments were conducted by varying the throat gas velocity, liquid level in outer cylinder, and inlet H₂S concentration. ANOVA test confirmed the significant effect of parameters on the removal efficiency. A quadratic equation has been obtained which predicts the removal efficiency very well. The suitability of the developed model has been judged by the higher R² square value which obtained from the regression analysis. From the investigation, it was found that the throat gas velocity has most significant effect and inlet concentration of H₂S has less effect on H₂S removal efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=desulfurization" title="desulfurization">desulfurization</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution%20control" title=" pollution control"> pollution control</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20methodology" title=" response surface methodology"> response surface methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=venturi%20scrubber" title=" venturi scrubber"> venturi scrubber</a> </p> <a href="https://publications.waset.org/abstracts/100513/optimization-of-effecting-parameters-for-the-removal-of-h2s-gas-in-self-priming-venturi-scrubber-using-response-surface-methodology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100513.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">139</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">42</span> A Comparative Study of Murayya Koenigii Varieties for the Removal of Cr (VI) from Aqueous Solutions </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mesfin%20Tsegaw">Mesfin Tsegaw</a>, <a href="https://publications.waset.org/abstracts/search?q=Sivakumar%20C.%20V."> Sivakumar C.

Cr (VI) is mobile in the environment, acutely toxic and carcinogenic. In the present study, the ability to remove Cr (VI) from aqueous solutions has been compared using leaves of dwarf and gamthi varieties of Murayya koerigii abundantly available in Selaqui region of Dehradun as an adsorbent. Effects of temperature, pH, initial concentration of adsorbate and adsorbent dosage have been studied for effective removal of Cr (VI). The biosorptive ability of biosorbent was reliant on the pH of the biosorbate, with pH 2 being most favorable for both the varieties. The obtained results were analyzed by the Freundlich and Langmuir equation at different temperature and related parameters were determined for each adsorption isotherm. The study also includes results on the kinetic dimensions of adsorption of the Cr (VI) on the derived adsorbent. Gamthi variety has a promising absorption rate of 80% over the dwarf variety. FTIR studies confirmed that carboxyl and hydroxyl groups were the main groups involved in the metal uptake. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=cromium" title=" cromium"> cromium</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetics" title=" kinetics"> kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=variety" title=" variety"> variety</a> </p> <a href="https://publications.waset.org/abstracts/84228/a-comparative-study-of-murayya-koenigii-varieties-for-the-removal-of-cr-vi-from-aqueous-solutions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84228.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Effect of Some Metal Ions on the Activity of Lipase Produced by Aspergillus Niger Cultured on Vitellaria Paradoxa Shells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulhakeem%20Sulyman">Abdulhakeem Sulyman</a>, <a href="https://publications.waset.org/abstracts/search?q=Olukotun%20Zainab"> Olukotun Zainab</a>, <a href="https://publications.waset.org/abstracts/search?q=Hammed%20Abdulquadri"> Hammed Abdulquadri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lipases (triacylglycerol acyl hydrolases) (EC 3.1.1.3) are class of enzymes that catalyses the hydrolysis of triglycerides to glycerol and free fatty acids. They account for up to 10% of the enzyme in the market and have a wide range of applications in biofuel production, detergent formulation, leather processing and in food and feed processing industry. This research was conducted to study the effect of some metal ions on the activity of purified lipase produced by Aspergillus niger cultured on Vitellaria paradoxa shells. Purified lipase in 12.5 mM p-NPL was incubated with different metal ions (Zn²⁺, Ca²⁺, Mn²⁺, Fe²⁺, Na⁺, K⁺ and Mg²⁺). The final concentrations of metal ions investigated were 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9 and 1.0 mM. The results obtained from the study showed that Zn²⁺, Ca²⁺, Mn²⁺ and Fe²⁺ ions increased the activity of lipase up to 3.0, 3.0, 1.0, and 26.0 folds respectively. Lipase activity was partially inhibited by Na⁺ and Mg²⁺ with up to 88.5% and 83.7% loss of activity respectively. Lipase activity was also inhibited by K⁺ with up to 56.7% loss in the activity as compared to in the absence of metal ions. The study concluded that lipase produced by Aspergillus niger cultured on Vitellaria paradoxa shells can be activated by the presence of Zn²⁺, Ca²⁺, Mn²⁺ and Fe²⁺ and inhibited by Na⁺, K⁺ and Mg²⁺. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aspergillus%20niger" title="Aspergillus niger">Aspergillus niger</a>, <a href="https://publications.waset.org/abstracts/search?q=Vitellaria%20paradoxa" title=" Vitellaria paradoxa"> Vitellaria paradoxa</a>, <a href="https://publications.waset.org/abstracts/search?q=lipase" title=" lipase"> lipase</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20ions" title=" metal ions"> metal ions</a> </p> <a href="https://publications.waset.org/abstracts/111953/effect-of-some-metal-ions-on-the-activity-of-lipase-produced-by-aspergillus-niger-cultured-on-vitellaria-paradoxa-shells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111953.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Determination of the Oxidative Potential of Organic Materials: Method Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jui%20Afrin">Jui Afrin</a>, <a href="https://publications.waset.org/abstracts/search?q=Akhtarul%20Islam"> Akhtarul Islam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the solution of glucose, yeast and glucose yeast mixture are being used as sample solution for determining the chemical oxygen demand (COD). In general COD determination method used to determine the different rang of oxidative potential. But in this work has shown to determine the definite oxidative potential for different concentration for known COD value and wanted to see the difference between experimental value and the theoretical value for evaluating the method drawbacks. In this study, made the values of oxidative potential like 400 mg/L, 500 mg/L, 600 mg/L, 700 mg/L and 800mg/L for various sample solutions and determined the oxidative potential according to our developed method. Plotting the experimental COD values vs. sample solutions of various concentrations in mg/L to draw the curve. From these curves see that the curves for glucose solution is not linear; its deviate from linearity for the lower concentration and the reason for this deviation is unknown. If these drawback can be removed this method can be effectively used to determine Oxidative Potential of Industrial wastewater (such as: Leather industry wastewater, Municipal wastewater, Food industry wastewater, Textile wastewater, Pharmaceuticals waste water) that’s why more experiment and study required. <p class="card-text"><strong>Keywords:</strong> <a
