Natural source-based blood-clotting bandages are rarely used. The available chemically treated blood clotting materials sometimes show adverse effects and are not effective in quick recovery. Considering these facts, a new blood clotting woven wound dressing product has been developed which is a combination of Micania micrantha extract with woven fabric by absorption process. This product can be represented as an important addition to medical textiles. To develop a dressing material, Micania micrantha leaf juice was applied on bleached woven fabric, followed by sun drying. The effectiveness of this woven sample was tested on volunteers. It was observed that Micania micrantha containing woven sample has a tremendous effect over conventional wound dressing materials. This result is a milestone for the textile and medical sector. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blood%20clotting" title="blood clotting">blood clotting</a>, <a href="https://publications.waset.org/abstracts/search?q=Micania%20micrantha" title=" Micania micrantha"> Micania micrantha</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20textiles" title=" medical textiles"> medical textiles</a>, <a href="https://publications.waset.org/abstracts/search?q=woven%20fabric" title=" woven fabric"> woven fabric</a> </p> <a href="https://publications.waset.org/abstracts/130568/effectiveness-of-micania-micrantha-extract-on-woven-wound-dressing-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130568.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">131</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">150</span> Preparation Non-Woven Nanofiber Structures for Uniform and Rapid Drug Releasing Applications Using an Electrospinning Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cho-Liang%20Chung">Cho-Liang Chung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Uniform and rapid drug release are important for trauma dressing application. Low glass transition polymer system and non-woven nanofiber structures as the designs conduct rapid-release characteristics. In this study, polyvinylpyrrolidone, polysulfone, and polystyrene were dissolved in dimethylformamide to form precursor solution. These solutions were blended with vitamin C to form the electrospinning solutions. The non-woven nanofibers structures were successfully prepared using an electrospinning process. The following instruments were used to analyze the characteristics of non-woven nanofibers structures: Atomic force microscopy (AFM), Field Emission Scanning Electron Microscope (FE-SEM), and X-ray Diffraction (XRD). The AFM was used to scan the nanofibers. 3D Graphics were applied to explore the surface morphology of nanofibers. FE-SEM was used to explore the morphology of non-woven structures. XRD was used to identify crystal structures in the non-woven structures. The evolution of morphology of non-woven structures was changed dramatically in different durations, because of the moisture absorption and decreasing glass transition temperature; the non-woven nanofiber structures can be applied to uniform and rapid drug release for trauma dressing application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanofibers" title="nanofibers">nanofibers</a>, <a href="https://publications.waset.org/abstracts/search?q=non-woven" title=" non-woven"> non-woven</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning%20process" title=" electrospinning process"> electrospinning process</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20drug%20releasing" title=" rapid drug releasing"> rapid drug releasing</a> </p> <a href="https://publications.waset.org/abstracts/95209/preparation-non-woven-nanofiber-structures-for-uniform-and-rapid-drug-releasing-applications-using-an-electrospinning-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95209.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">149</span> Modification of Four Layer through the Thickness Woven Structure for Improved Impact Resistance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Liaqat">Muhammad Liaqat</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafiz%20Abdul%20Samad"> Hafiz Abdul Samad</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Talha%20Ali%20Hamdani"> Syed Talha Ali Hamdani</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasir%20Nawab"> Yasir Nawab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the current research, the four layers, orthogonal through the thickness, 2D woven, 3D fabric structure was modified to improve the impact resistance of 3D fabric reinforced composites.

Compression therapy is the universally accepted treatment for the management of hypertrophic scarring after severe burns. Mostly stretchable knitted fabrics are used in compression therapy but in the recent past, some studies have also been found on bi-stretch woven fabrics being used as compression garments as they also have been found quite effective in the treatment of oedema. Therefore, the objective of the present study is to compare the compression properties of stretchable knitted and bi-stretch woven fabrics for compression garments. For this purpose four woven structures and four knitted structures were produced having the same areal density and their compression, comfort and mechanical properties were compared before and after 5, 10 and 15 washes. Four knitted structures used were single jersey, single locaste, plain pique and the honeycomb, whereas four woven structures produced were 1/1 plain, 2/1 twill, 3/1 twill and 4/1 twill. The compression properties of the produced samples were tested by using kikuhime pressure sensor and it was found that bi-stretch woven fabrics possessed better compression properties before and after washes and retain their durability after repeated use, whereas knitted stretchable fabrics lost their compression ability after repeated use and the required sub garment pressure of the knitted structures after 15 washes was almost half to that of woven bi-stretch fabrics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compression%20garments" title="compression garments">compression garments</a>, <a href="https://publications.waset.org/abstracts/search?q=knitted%20structures" title=" knitted structures"> knitted structures</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20textiles" title=" medical textiles"> medical textiles</a>, <a href="https://publications.waset.org/abstracts/search?q=woven%20bi-stretch" title=" woven bi-stretch"> woven bi-stretch</a> </p> <a href="https://publications.waset.org/abstracts/39769/comparison-of-compression-properties-of-stretchable-knitted-fabrics-and-bi-stretch-woven-fabrics-for-compression-garments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39769.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">412</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">147</span> Investigation on Hand-Woven School Uniform Initiative and Sustainability: The Kerala Model from India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abhilash%20Balan%20Paleri">Abhilash Balan Paleri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hand woven fabric embellishes an exceptional identity in the social milieu of Kerala; still, the artisans and handloom sector is undergoing crisis due to various reasons. The hand woven school uniform initiative of Govt. of Kerala launched in 2016 aims at enhancing the sector, ensuring sustainability at artisan and end-user levels. The Kerala Government already distributed 23 lakhs meters of cloth (for shirting, suiting, and skirting) woven by 4085 artisans in their traditional looms covering 4.5 lakhs of students in the public education sector which covers cover 3,701 schools in the state. The 2019-20 year production is expected to be 42 Lakhs meters of hand woven clothing catering 8.6 lakhs of students in the primary sector. This particular investigation unveils the upshots of the initiative, and the observations are derived through systematic enquiry with artisans, authorities, and end-users.

The suggestions of a better process of production were recommended in this study. This survey research was conducted by using a questionnaire and interview, which were considered as the practical instruments to collect the data. The 200 Kraseasin’s woven makers and consumers were subjects by using a purposive sampling. Percentages, means and standard deviation were used to analyze data. The findings revealed that only 22 local woven members owned their 18 manual weavers in producing the raw materials like cotton or fiber. The main products were flowery woven cloth e.g. pikul, puangchompoo, pakakrong and ban mai roo roiy, and the others were rainy, glass wall, dice glass ball and yok dok etc. At the present, all local woven products were applied to be modernized but the strong point of those products were keeping the quality standard and firming textures, not thickness. The main objective of producing these local woven products was to earn and increase their extra incomes. Moreover, there were two dominant sales: Firstly, the makers sold their own products by themselves in their community and malls; and secondly, they would weave their products by customers’ orders. The prices’ allocation was on the difficulties in producing process. The government officials and non-government officials in local were normally customers. However the drawback of producing this local product was lack of raw material and this brought about the higher investment. The community’s customers were now lacking of interest in wearing these local products, even though they maintained their quality standard. The factors in customers’ purchasing decision were product (M = 3.93), price (M = 3.74), distribution (M = 3.73) and promotion (M = 3.97) for marketing mix well-known. Suggestion was a designing pattern of products had to be matched to the customers’ needs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=marketing" title="marketing">marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=consumer%20behavior" title=" consumer behavior"> consumer behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=cloth%20products%20weaves" title=" cloth products weaves"> cloth products weaves</a>, <a href="https://publications.waset.org/abstracts/search?q=Songkhla%20Thailand" title=" Songkhla Thailand"> Songkhla Thailand</a> </p> <a href="https://publications.waset.org/abstracts/6562/the-marketing-development-of-cloth-products-woven-in-krasaesin-songkhla-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6562.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">284</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">145</span> The Inhibition of Relapse of Orthodontic Tooth Movement by NaF Administration in Expressions of TGF-β1, Runx2, Alkaline Phosphatase and Microscopic Appearance of Woven Bone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Sutjiati">R.

The aim of this study is to experimentally test the inhibition of relapse of orthodontics tooth movement in NaF of expression TGF-β1, Runx2, alkaline phosphatase (ALP) and microscopic of woven bone. The research method used was experimental laboratory research involving 30 rats, which were divided into three groups. Group A: rats were not given orthodontic tooth movement and without NaF. Group B: rats were given orthodontic tooth movement and without 11.5 ppm by topical application. Group C: rats were given orthodontic tooth movement and 11.75 ppm by topical application. Orthodontic tooth movement was conducted by applying ligature wires of 0.02 mm in diameter on the molar-1 (M-1) of left permanent maxilla and left insisivus of maxilla. Immunohistochemical examination was conducted to calculate the number of osteoblast to determine TGF β1, Runx2, ALP and haematoxylin to determine woven bone on day 7 and day 14. Results: It was shown that administrations of Natrium Fluoride topical application proved effective to increase the expression of TGF-β1, Runx2, ALP and to increase woven bone in the tension area greater than administration without natrium fluoride topical application (p < 0.05), except the expression of ALP on day 7 and day 14 which was significant. The results of the study show that NaF significantly increases the expressions of TGF-β1, Runx2, ALP and woven bone. The expression of the variables enhanced on day 7 compared on that on day 14, except ALP. Thus, it can be said that the acceleration of woven bone occurs on day 7. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=TGF-%CE%B21" title="TGF-β1">TGF-β1</a>, <a href="https://publications.waset.org/abstracts/search?q=Runx2" title=" Runx2"> Runx2</a>, <a href="https://publications.waset.org/abstracts/search?q=ALP" title=" ALP"> ALP</a>, <a href="https://publications.waset.org/abstracts/search?q=woven%20bone" title=" woven bone"> woven bone</a>, <a href="https://publications.waset.org/abstracts/search?q=natrium%20fluoride" title=" natrium fluoride"> natrium fluoride</a> </p> <a href="https://publications.waset.org/abstracts/68483/the-inhibition-of-relapse-of-orthodontic-tooth-movement-by-naf-administration-in-expressions-of-tgf-v1-runx2-alkaline-phosphatase-and-microscopic-appearance-of-woven-bone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68483.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">233</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">144</span> Effect of Weave Structure and Picking Sequence on the Comfort Properties of Woven Fabrics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Umair">Muhammad Umair</a>, <a href="https://publications.waset.org/abstracts/search?q=Tanveer%20Hussain"> Tanveer Hussain</a>, <a href="https://publications.waset.org/abstracts/search?q=Khubab%20Shaker"> Khubab Shaker</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasir%20Nawab"> Yasir Nawab</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Maqsood"> Muhammad Maqsood</a>, <a href="https://publications.waset.org/abstracts/search?q=Madeha%20Jabbar"> Madeha Jabbar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The term comfort is defined as 'the absence of unpleasantness or discomfort' or 'a neutral state compared to the more active state'. Comfort mainly is of three types: sensorial (tactile) comfort, psychological comfort and thermo-physiological comfort. Thermophysiological comfort is determined by the air permeability and moisture management properties of the garment. The aim of this study was to investigate the effect of weave structure and picking sequence on the comfort properties of woven fabrics. Six woven fabrics with two different weave structures i.e. 1/1 plain and 3/1 twill and three different picking sequences: (SPI, DPI, 3PI) were taken as input variables whereas air permeability, wetting time, wicking behavior and overall moisture management capability (OMMC) of fabrics were taken as response variables and a comparison is made of the effect of weave structure and picking sequence on the response variables. It was found that fabrics woven in twill weave design and with simultaneous triple pick insertion (3PI) give significantly better air permeability, shorter wetting time and better water spreading rate, as compared to plain woven fabrics and those with double pick insertion (DPI) or single pick insertion (SPI). It could be concluded that the thermophysiological comfort of woven fabrics may be significantly improved simply by selecting a suitable weave design and picking sequence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20permeability" title="air permeability">air permeability</a>, <a href="https://publications.waset.org/abstracts/search?q=picking%20sequence" title=" picking sequence"> picking sequence</a>, <a href="https://publications.waset.org/abstracts/search?q=thermophysiological%20comfort" title=" thermophysiological comfort"> thermophysiological comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=weave%20design" title=" weave design"> weave design</a> </p> <a href="https://publications.waset.org/abstracts/33959/effect-of-weave-structure-and-picking-sequence-on-the-comfort-properties-of-woven-fabrics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33959.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">419</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">143</span> Porosity and Ultraviolet Protection Ability of Woven Fabrics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Polona%20Dobnik%20Dubrovski">Polona Dobnik Dubrovski</a>, <a href="https://publications.waset.org/abstracts/search?q=Abhijit%20Majumdar"> Abhijit Majumdar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increasing awareness of negative effects of ultraviolet radiation and regular, effective protection are actual themes in many countries. Woven fabrics as clothing items can provide convenient personal protection however not all fabrics offer sufficient UV protection. Porous structure of the material has a great effect on UPF. The paper is focused on an overview of porosity in woven fabrics, including the determination of porosity parameters on the basis of an ideal geometrical model of porous structure. Our experiment was focused on 100% cotton woven fabrics in a grey state with the same yarn fineness (14 tex) and different thread densities (to achieve relative fabric density between 59 % and 87 %) and different type of weaves (plain, 4-end twill, 5-end satin). The results of the research dealing with the modelling of UPF and the influence of volume and open porosity of tested samples on UPF are exposed. The results show that open porosity should be lower than 12 % to achieve good UV protection according to AS/NZ standard of tested samples. The results also indicate that there is no direct correlation between volume porosity and UPF, moreover, volume porosity namely depends on the type of weave and affects UPF as well. Plain fabrics did not offer any UV protection, while twill and satin fabrics offered good UV protection when volume porosity was less than 64 % and 66 %, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fabric%20engineering" title="fabric engineering">fabric engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=UV%20radiation" title=" UV radiation"> UV radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20materials" title=" porous materials"> porous materials</a>, <a href="https://publications.waset.org/abstracts/search?q=woven%20fabric%20construction" title=" woven fabric construction"> woven fabric construction</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a> </p> <a href="https://publications.waset.org/abstracts/45594/porosity-and-ultraviolet-protection-ability-of-woven-fabrics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45594.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">268</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">142</span> Mitigation of Size Effects in Woven Fabric Composites Using Finite Element Analysis Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azeez%20Shaik">Azeez Shaik</a>, <a href="https://publications.waset.org/abstracts/search?q=Yagnik%20Kalariya"> Yagnik Kalariya</a>, <a href="https://publications.waset.org/abstracts/search?q=Amit%20Salvi"> Amit Salvi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High-performance requirements and emission norms were forcing the automobile industry to opt for lightweight materials which improve the fuel efficiency and absorb energy during crash applications.

When 3D woven preforms are produced, they are in their optimal physical state. As 3D weaving is a dry preforming technology it relies on compression of the preform to achieve the desired composite thickness, fibre volume fraction (Vf) and consolidation. This compression of the preform during manufacture results in changes to its thickness and architecture which can often lead to under-performance or changes of the 3D woven composite. Unlike traditional 2D fabrics, the bespoke nature and variability of 3D woven architectures makes it difficult to know exactly how each 3D preform will behave during processing. Therefore, the focus of this study is to investigate the effect of compression on differing 3D woven architectures in terms of structure, crimp or fibre waviness and thickness as well as analysing the accuracy of available software to predict how 3D woven preforms behave under compression. To achieve this, 3D preforms are modelled and compression simulated in Wisetex with varying architectures of binder style, pick density, thickness and tow size. These architectures have then been woven with samples dry compression tested to determine the compressibility of the preforms under various pressures. Additional preform samples were manufactured using Resin Transfer Moulding (RTM) with varying compressive force. Composite samples were cross sectioned, polished and analysed using microscopy to investigate changes in architecture and crimp. Data from dry fabric compression and composite samples were then compared alongside the Wisetex models to determine accuracy of the prediction and identify architecture parameters that can affect the preform compressibility and stability. Results indicate that binder style/pick density, tow size and thickness have a significant effect on compressibility of 3D woven preforms with lower pick density allowing for greater compression and distortion of the architecture. It was further highlighted that binder style combined with pressure had a significant effect on changes to preform architecture where orthogonal binders experienced highest level of deformation, but highest overall stability, with compression while layer to layer indicated a reduction in fibre crimp of the binder. In general, simulations showed a relative comparison to experimental results; however, deviation is evident due to assumptions present within the modelled results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20woven%20composites" title="3D woven composites">3D woven composites</a>, <a href="https://publications.waset.org/abstracts/search?q=compression" title=" compression"> compression</a>, <a href="https://publications.waset.org/abstracts/search?q=preforms" title=" preforms"> preforms</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20composites" title=" textile composites"> textile composites</a> </p> <a href="https://publications.waset.org/abstracts/123463/an-investigation-into-the-influence-of-compression-on-3d-woven-preform-thickness-and-architecture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123463.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">135</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">140</span> Development of Stretchable Woven Fabrics with Auxetic Behaviour</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adeel%20Zulifqar">Adeel Zulifqar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Hu"> Hong Hu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Auxetic fabrics are a special kind of textile materials which possess negative Poisson’s ratio. Opposite to most of the conventional fabrics, auxetic fabrics get bigger in the transversal direction when stretched or get smaller when compressed. Auxetic fabrics are superior to conventional fabrics because of their counterintuitive properties, such as enhanced porosity under the extension, excellent formability to a curved surface and high energy absorption ability. Up till today, auxetic fabrics have been produced based on two approaches. The first approach involves using auxetic fibre or yarn and weaving technology to fabricate auxetic fabrics. The other method to fabricate the auxetic fabrics is by using non-auxetic yarns. This method has gained extraordinary curiosity of researcher in recent years. This method is based on realizing auxetic geometries into the fabric structure. In the woven fabric structure auxetic geometries can be realized by creating a differential shrinkage phenomenon into the fabric structural unit cell. This phenomenon can be created by using loose and tight weave combinations within the unit cell of interlacement pattern along with elastic and non-elastic yarns. Upon relaxation, the unit cell of interlacement pattern acquires a non-uniform shrinkage profile due to different shrinkage properties of loose and tight weaves in designed pattern, and the auxetic geometry is realized. The development of uni-stretch auxetic woven fabrics and bi-stretch auxetic woven fabrics by using this method has already been reported. This study reports the development of another kind of bi-stretch auxetic woven fabric. The fabric is first designed by transforming the auxetic geometry into interlacement pattern and then fabricated, using the available conventional weaving technology and non-auxetic elastic and non-elastic yarns. The tensile tests confirmed that the developed bi-stretch auxetic woven fabrics exhibit negative Poisson’s ratio over a wide range of tensile strain. Therefore, it can be concluded that the auxetic geometry can be realized into the woven fabric structure by creating the phenomenon of differential shrinkage and bi-stretch woven fabrics made of non-auxetic yarns having auxetic behavior and stretchability are possible can be obtained.

A user menu is provided to help define parameters for the FE models, such as type and size of the elements in fabric and matrix as well as the type of matrix-fabric interaction. Node-to-node constraints were imposed to guarantee periodicity of the deformed shapes at the boundaries of the representative volume element of the composite. Tensile loads in three axes and biaxial loads in <em>x-y</em> directions have been applied at different Fibre Volume Fractions (FVFs).

New class of 2D and 3D textile and woven fabric composites offer excellent fracture toughens as they bridge the cracks formed during fracture. Due to complexity of their fiber architectures and its resulting composite microstructures, optimized design and analysis of these structures is very complicated. A traditional homogenization approach is typically used to analyze structures made up of these materials. This approach usually fails to predict damage initiation as well as damage propagation and ultimate failure of structure made up of woven and textile composites. This study demonstrates a methodology to analyze woven and textile composites by using the multi-level multi-scale modelling approach. In this approach, a geometric repetitive unit cell (RUC) is developed with all its constituents to develop a representative volume element (RVE) with all its constituents and their interaction modeled correctly. The structure is modeled based on the RUC/RVE and analyzed at different length scales with desired levels of fidelity incorporating the damage and failure. The results are passed across (up and down) the scales qualitatively as well as quantitatively from the perspective of material, configuration and architecture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cohesive%20zone" title="cohesive zone">cohesive zone</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-scale%20modeling" title=" multi-scale modeling"> multi-scale modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=rate%20dependency" title=" rate dependency"> rate dependency</a>, <a href="https://publications.waset.org/abstracts/search?q=RUC" title=" RUC"> RUC</a>, <a href="https://publications.waset.org/abstracts/search?q=woven%20textiles" title=" woven textiles"> woven textiles</a> </p> <a href="https://publications.waset.org/abstracts/35426/a-multi-scale-approach-for-the-analysis-of-fiber-reinforced-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35426.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">361</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">136</span> Elastic Stress Analysis of Composite Cantilever Beam Loaded Uniformly</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Merve%20Tunay%20%C3%87etin">Merve Tunay Çetin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Kur%C5%9Fun"> Ali Kurşun</a>, <a href="https://publications.waset.org/abstracts/search?q=Erhan%20%C3%87etin"> Erhan Çetin</a>, <a href="https://publications.waset.org/abstracts/search?q=Halil%20Aykul"> Halil Aykul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this investigation an elastic stress analysis is carried out a woven steel fiber reinforced thermoplastic cantilever beam loaded uniformly at the upper surface.

The results show that orientation angle play an important role in determining the responses of a woven steel fiber reinforced thermoplastic cantilever beams and an optimal design of these structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cantilever%20beam" title="cantilever beam">cantilever beam</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic%20stress%20analysis" title=" elastic stress analysis"> elastic stress analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=orientation%20angle" title=" orientation angle"> orientation angle</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoplastic" title=" thermoplastic "> thermoplastic </a> </p> <a href="https://publications.waset.org/abstracts/2632/elastic-stress-analysis-of-composite-cantilever-beam-loaded-uniformly" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2632.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">498</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">135</span> Flexural Response of Glass Fiber Reinforced Polymer Sandwich Panels with 3D Woven Honeycomb Core</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elif%20Kalkanli">Elif Kalkanli</a>, <a href="https://publications.waset.org/abstracts/search?q=Constantinos%20Soutis"> Constantinos Soutis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of textile preform in the advanced fields including aerospace, automotive and marine has exponentially grown in recent years. These preforms offer excellent advantages such as being lightweight and low-cost, and also, their suitability for creating different fiber architectures with different materials whilst improved mechanical properties in certain aspects. In this study, a novel honeycomb core is developed by a 3Dweaving process. The assembly of the layers is achieved thanks to innovative weaving design. Polyester yarn is selected for the 3D woven honeycomb core (3DWHC). The core is used to manufacture a sandwich panel with 2x2 twill glass fiber composite face sheets. These 3DWHC sandwich panels will be tested in three-point bending. The in-plane and out-of-plane (through-the-thickness) mechanical response of the core will be examined as a function of cell size in addition to the flexural response of the sandwich panel. The failure mechanisms of the core and the sandwich skins will be reported in addition to flexural strength and stiffness. Possible engineering applications will be identified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20woven" title="3D woven">3D woven</a>, <a href="https://publications.waset.org/abstracts/search?q=assembly" title=" assembly"> assembly</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20modes" title=" failure modes"> failure modes</a>, <a href="https://publications.waset.org/abstracts/search?q=honeycomb%20sandwich%20panel" title=" honeycomb sandwich panel"> honeycomb sandwich panel</a> </p> <a href="https://publications.waset.org/abstracts/75038/flexural-response-of-glass-fiber-reinforced-polymer-sandwich-panels-with-3d-woven-honeycomb-core" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75038.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">206</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">134</span> Fiber-Based 3D Cellular Reinforcing Structures for Mineral-Bonded Composites with Enhanced Structural Impact Tolerance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Duy%20M.%20P.%20Vo">Duy M.

The research training group GRK 2250/1 aims to develop mineral-bonded composites that allow the fabrication of thin-layered strengthening layers providing available concrete members with enhanced impact resistance. This paper presents the development of 3D woven wire cellular structures that can be used as innovative reinforcement for targeted composites. 3D woven wire cellular structures are truss-like architectures that can be fabricated in an automatized process with a great customization possibility. The specific architecture allows this kind of structures to have good load bearing capability and forming behavior, which is of great potential to give strength against impact loading. An appropriate combination of topology and material enables an optimal use of thin-layered reinforcement in concrete constructions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20woven%20cellular%20structures" title="3D woven cellular structures">3D woven cellular structures</a>, <a href="https://publications.waset.org/abstracts/search?q=ductile%20behavior" title=" ductile behavior"> ductile behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20absorption" title=" energy absorption"> energy absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber-based%20reinforced%20concrete" title=" fiber-based reinforced concrete"> fiber-based reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20resistant" title=" impact resistant"> impact resistant</a> </p> <a href="https://publications.waset.org/abstracts/92338/fiber-based-3d-cellular-reinforcing-structures-for-mineral-bonded-composites-with-enhanced-structural-impact-tolerance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92338.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">298</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">133</span> Use of Non-woven Polyethylene Terephthalate Fabrics to Improve Certain Properties of Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sifatullah%20Bahij">Sifatullah Bahij</a>, <a href="https://publications.waset.org/abstracts/search?q=Safiullah%20Omary"> Safiullah Omary</a>, <a href="https://publications.waset.org/abstracts/search?q=Francoise%20Feugeas"> Francoise Feugeas</a>, <a href="https://publications.waset.org/abstracts/search?q=Amanullah%20Faqiri"> Amanullah Faqiri </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plastic packages have been broadly used for a long time. Such widespread usage of plastic has resulted in an increased amount of plastic wastes and many environmental impacts. Plastic wastes are one of the most significant types of waste materials because of their non-degradation and low biodegradability. It is why many researchers tried to find a safe and environmentally friendly solution for plastic wastes. In this goal, in the civil engineering industry, many types of plastic wastes have been incorporated, as a partial substitution of aggregates or as additive materials (fibers) in concrete mixtures because of their lengthier lifetime and lower weight. This work aims to study the mechanical properties (compressive, split tensile and flexural strengths) of concrete with a water-cement ratio (w/c) of 0.45 and with the incorporation of non-woven PET plastic sheets. Five configurations -without PET (reference), 1-layer sheet, 2-side, 3-side, and full sample wrapping- were applied. The 7, 14 and 28-days samples’ compressive strengths, flexural strength and split tensile strength were measured. The outcomes of the study show that the compressive strength was improved for the wrapped samples, particularly for the cylindrical specimens. Also, split tensile and flexural behaviors of the wrapped samples improved significantly compared to the reference ones. Moreover, reference samples were damaged into many parts after mechanical testing, while wrapped specimens were taken by the applied configurations and were not divided into many small fragments. Therefore, non-woven fabrics appeared to improve some properties of the concrete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solid%20waste%20plastic" title="solid waste plastic">solid waste plastic</a>, <a href="https://publications.waset.org/abstracts/search?q=non-woven%20polyethylene%20terephthalate%20sheets" title=" non-woven polyethylene terephthalate sheets"> non-woven polyethylene terephthalate sheets</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20behaviors" title=" mechanical behaviors"> mechanical behaviors</a>, <a href="https://publications.waset.org/abstracts/search?q=crack%20pattern" title=" crack pattern"> crack pattern</a> </p> <a href="https://publications.waset.org/abstracts/125310/use-of-non-woven-polyethylene-terephthalate-fabrics-to-improve-certain-properties-of-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125310.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">132</span> Substantiate the Effects of Reactive Dyes and Aloe Vera on the Ultra Violet Protective Properties on Cotton Woven and Knitted Fabrics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neha%20Singh">Neha Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The incidence of skin cancer has been rising worldwide due to excessive exposure to sun light. Climatic changes and depletion of ozone layer allow the easy entry of UV rays on earth, resulting skin damages such as sunburn, premature skin ageing, allergies and skin cancer. Researches have suggested many modes for protection of human skin against ultraviolet radiation; avoidance to outdoor activities, using textiles for covering the skin, sunscreen and sun glasses. However, this paper gives an insight about how textile material specially woven and knitted cotton can be efficiently utilized for protecting human skin from the harmful ultraviolet radiations by combining reactive dyes with Aloe Vera. Selection of the fabric was based on their utility and suitability as per the climate condition of the country for the upper and lower garment. A standard dyeing process was used, and Aloe Vera molecules were applied by in-micro encapsulation technique. After combining vat dyes with Aloe Vera excellent UPF (Ultra violet Protective Factor) was observed. There is a significant change in the UPF of vat dyed cotton fabric after treatment with Aloe Vera. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=UV%20protection" title="UV protection">UV protection</a>, <a href="https://publications.waset.org/abstracts/search?q=aloe%20vera" title=" aloe vera"> aloe vera</a>, <a href="https://publications.waset.org/abstracts/search?q=protective%20clothing" title=" protective clothing"> protective clothing</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20dyes" title=" reactive dyes"> reactive dyes</a>, <a href="https://publications.waset.org/abstracts/search?q=cotton" title=" cotton"> cotton</a>, <a href="https://publications.waset.org/abstracts/search?q=woven%20and%20knits" title=" woven and knits"> woven and knits</a> </p> <a href="https://publications.waset.org/abstracts/79095/substantiate-the-effects-of-reactive-dyes-and-aloe-vera-on-the-ultra-violet-protective-properties-on-cotton-woven-and-knitted-fabrics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79095.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">261</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">131</span> Delamination Fracture Toughness Benefits of Inter-Woven Plies in Composite Laminates Produced through Automated Fibre Placement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jayden%20Levy">Jayden Levy</a>, <a href="https://publications.waset.org/abstracts/search?q=Garth%20M.%20K.%20Pearce"> Garth M.

Termed ‘inter-weaving’, the method uses custom placement sequences of thermoset prepreg tows to distribute regular fibre link regions in traditionally clean ply interfaces. Inter-weaving’s impact on mode I delamination fracture toughness was evaluated experimentally through double cantilever beam tests (ASTM standard D5528-13) on [±15°]9 laminates made from Park Electrochemical Corp. E-752-LT 1/4” carbon fibre prepreg tape. Unwoven and inter-woven automated fibre placement samples were compared to those of traditional laminates produced from standard uni-directional plies of the same material system. Unwoven automated fibre placement laminates were found to suffer a mostly constant 3.5% decrease in mode I delamination fracture toughness compared to flat uni-directional plies. Inter-weaving caused significant local fracture toughness increases (up to 50%), though these were offset by a matching overall reduction. These positive and negative behaviours of inter-woven laminates were respectively found to be caused by fibre breakage and matrix deformation at inter-weave sites, and the 3D layering of inter-woven ply interfaces providing numerous paths of least resistance for crack propagation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AFP" title="AFP">AFP</a>, <a href="https://publications.waset.org/abstracts/search?q=automated%20fibre%20placement" title=" automated fibre placement"> automated fibre placement</a>, <a href="https://publications.waset.org/abstracts/search?q=delamination" title=" delamination"> delamination</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture%20toughness" title=" fracture toughness"> fracture toughness</a>, <a href="https://publications.waset.org/abstracts/search?q=inter-weaving" title=" inter-weaving"> inter-weaving</a> </p> <a href="https://publications.waset.org/abstracts/80136/delamination-fracture-toughness-benefits-of-inter-woven-plies-in-composite-laminates-produced-through-automated-fibre-placement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80136.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">184</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">130</span> Innovative Handloom Design Techniques- an Experimental Study Based on Primary Colour Gradation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akanksha%20Pareek">Akanksha Pareek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Indian Handloom clusters are known for its tradition and heritage of excellent craftsmanship.

Many objective and subjective techniques have been developed to analyze HoT, however none of them provide exact overall information concerning the sensation of textiles through the skin. As the human skin is a complex heterogeneous hyperelastic body composed of many particles, some simplifications had to be made at the stage of building the models. The same concerns models of woven structures, however their utilitarian value was maintained. The models reflect only friction between skin and woven textiles, deformation of the skin and fabrics when “touching” textiles and heat transfer from the surface of the skin into direction of textiles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fingertip%20skin%20models" title="fingertip skin models">fingertip skin models</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20models" title=" finite element models"> finite element models</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling%20of%20textiles" title=" modelling of textiles"> modelling of textiles</a>, <a href="https://publications.waset.org/abstracts/search?q=sensation%20of%20textiles%20through%20the%20skin" title=" sensation of textiles through the skin"> sensation of textiles through the skin</a> </p> <a href="https://publications.waset.org/abstracts/26064/analysis-of-tactile-perception-of-textiles-by-fingertip-skin-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26064.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">465</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">128</span> Study of the Effect of Sewing on Non Woven Textile Waste at Dry and Composite Scales</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wafa%20Baccouch">Wafa Baccouch</a>, <a href="https://publications.waset.org/abstracts/search?q=Adel%20Ghith"> Adel Ghith</a>, <a href="https://publications.waset.org/abstracts/search?q=Xavier%20Legrand"> Xavier Legrand</a>, <a href="https://publications.waset.org/abstracts/search?q=Faten%20Fayala"> Faten Fayala</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Textile waste recycling has become a necessity considering the augmentation of the amount of waste generated each year and the ecological problems that landfilling and burning can cause. Textile waste can be recycled into many different forms according to its composition and its final utilization. Using this waste as reinforcement to composite panels is a new recycling area that is being studied. Compared to virgin fabrics, recycled ones present the disadvantage of having lower structural characteristics, when they are eco-friendly and with low cost. The objective of this work is transforming textile waste into composite material with good characteristic and low price. In this study, we used sewing as a method to improve the characteristics of the recycled textile waste in order to use it as reinforcement to composite material. Textile non-woven waste was afforded by a local textile recycling industry. Performances tests were evaluated using tensile testing machine and based on the testing direction for both reinforcements and composite panels; machine and transverse direction. Tensile tests were conducted on sewed and non sewed fabrics, and then they were used as reinforcements to composite panels via epoxy resin infusion method. Rule of mixtures is used to predict composite characteristics and then compared to experimental ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20material" title="composite material">composite material</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy%20resin" title=" epoxy resin"> epoxy resin</a>, <a href="https://publications.waset.org/abstracts/search?q=non%20woven%20waste" title=" non woven waste"> non woven waste</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling" title=" recycling"> recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=sewing" title=" sewing"> sewing</a>, <a href="https://publications.waset.org/abstracts/search?q=textile" title=" textile"> textile</a> </p> <a href="https://publications.waset.org/abstracts/101055/study-of-the-effect-of-sewing-on-non-woven-textile-waste-at-dry-and-composite-scales" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101055.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">586</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">127</span> Reinforcement Effect on Dynamic Properties of Saturated Sand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Ziaie%20Moayed">R.

Sound can be considered as a wave phenomenon. A sound wave is a longitudinal wave where particles of the medium are temporarily displaced in a direction parallel to energy transport and then return to their original position. The vibration in a medium produces alternating waves of relatively dense and sparse particles –compression and rarefaction respectively. The resultant variation to normal ambient pressure is translated by the ear and perceived as sound. Today much importance is given to the acoustical environment. The noise sources are increased day by day and annoying level is strongly violated in different locations by traffic, sound systems, and industries. There is simple evidence showing that the high noise levels cause sleep disturbance, hearing loss, decrease in productivity, learning disability, lower scholastic performance and increase in stress related hormones and blood pressure. Therefore, achieving a pleasing and noise free environment is one of the endeavours of many a research groups. This can be obtained by using various techniques. One such technique is by using suitable materials with good sound absorbing properties. The conventionally used materials that possess sound absorbing properties are rock wool or glass wool. In this work, an attempt is made to use synthetic material in both fibrous and sheet form and use it for manufacturing of non-woven for sound absorption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustics" title="acoustics">acoustics</a>, <a href="https://publications.waset.org/abstracts/search?q=fibre" title=" fibre"> fibre</a>, <a href="https://publications.waset.org/abstracts/search?q=non-woven" title=" non-woven"> non-woven</a>, <a href="https://publications.waset.org/abstracts/search?q=noise" title=" noise"> noise</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20absorption%20properties" title=" sound absorption properties"> sound absorption properties</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20absorption%20coefficient" title=" sound absorption coefficient"> sound absorption coefficient</a> </p> <a href="https://publications.waset.org/abstracts/66969/development-and-characterization-of-synthetic-non-woven-for-sound-absorption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66969.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">301</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">125</span> Study of Mechanical Properties of Leno Woven Bags in Lower Weight Capacities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Golda%20Honey%20Madhu">Golda Honey Madhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Priyanka%20Gupta"> Priyanka Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Anil%20Kumar%20Yadav"> Anil Kumar Yadav</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study is aimed at analyzing and understanding the design and performance properties of leno woven sacks specifically meant for holding lower weight goods under the category of lower weight capacities. The sacks are a huge part of the agro-based packaging industries which helps in keeping the perishable produce, especially fruits, fresh during transit and storage. Nowadays, Leno bags are primarily made from polypropylene, mainly due its cost-effectiveness, reusability and high strength with low weight property making it an ideal packaging solution for transportation. The design parameters are noted, and major properties like tensile strength, abrasion resistance, bursting strength, impact resistance, stiffness and bagging behaviour has been analyzed for lower weight capacities. An examination of these particular weight categories will provide valuable information on how to scale performance. Currently there are standards available for only 25 kg and 50 kg Leno sacks, and this study will further enhance the already existing testing standards and also provide tested structure-property analysis for lower weight Leno sacks. Hence the results of this research can provide significant insights for researchers, manufacturers and industry-experts with the goal of improving the quality and longevity of Leno woven sacks, thereby developing the packaging technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leno%20bags" title="leno bags">leno bags</a>, <a href="https://publications.waset.org/abstracts/search?q=structure-property%20analysis" title=" structure-property analysis"> structure-property analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=agro-based%20packaging" title=" agro-based packaging"> agro-based packaging</a>, <a href="https://publications.waset.org/abstracts/search?q=lower%20weight%20sacks" title=" lower weight sacks"> lower weight sacks</a> </p> <a href="https://publications.waset.org/abstracts/191694/study-of-mechanical-properties-of-leno-woven-bags-in-lower-weight-capacities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191694.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">21</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">124</span> Seam Slippage of Light Woven Fabrics with Regards to Sewing Parameters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mona%20Shawky">Mona Shawky</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20M.%20Elsheikh"> Khaled M.

The seam quality of the garment is a term that indicates both the aesthetic and functional performance of the garment. Seam slippage is one of the important properties that determine garment performance. Lightweight fabrics are preferred for their aesthetic properties. Since seam slippage is one of the most occurable faults for woven garments, in this study, a design of experiment of the following sewing parameters (three levels of needle size, three levels of stitch density, three levels of the seam allowance, two levels of sewing thread count, and two fabric types) was used to obtain the effect of the interaction between different sewing parameters on-seam slippage force. Two lightweight polyester woven fabrics with different constructions were used with lock stitch 301 to perform this study. Regression equations which can predict seam slippage force in both warp and weft directions were concluded. It was found that fabric type has a significant positive effect on seam slippage force in the warp direction, while it has a significant negative effect on seam slippage force on weft direction. Also, the interaction between needle size and stitch density has a significant positive effect on seam slippage force on warp direction, while the interaction between stitch density and seam allowance has a negative effect on seam slippage force in the weft direction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=needle%20size" title="needle size">needle size</a>, <a href="https://publications.waset.org/abstracts/search?q=regression%20equation" title=" regression equation"> regression equation</a>, <a href="https://publications.waset.org/abstracts/search?q=seam%20allowance" title=" seam allowance"> seam allowance</a>, <a href="https://publications.waset.org/abstracts/search?q=seam%20slippage" title=" seam slippage"> seam slippage</a>, <a href="https://publications.waset.org/abstracts/search?q=stitch%20density" title=" stitch density"> stitch density</a> </p> <a href="https://publications.waset.org/abstracts/128316/seam-slippage-of-light-woven-fabrics-with-regards-to-sewing-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128316.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">160</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">123</span> Micro-Meso 3D FE Damage Modelling of Woven Carbon Fibre Reinforced Plastic Composite under Quasi-Static Bending</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aamir%20Mubashar">Aamir Mubashar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Fiaz"> Ibrahim Fiaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research presents a three-dimensional finite element modelling strategy to simulate damage in a quasi-static three-point bending analysis of woven twill 2/2 type carbon fibre reinforced plastic (CFRP) composite on a micro-meso level using cohesive zone modelling technique. A meso scale finite element model comprised of a number of plies was developed in the commercial finite element code Abaqus/explicit. The interfaces between the plies were explicitly modelled using cohesive zone elements to allow for debonding by crack initiation and propagation. Load-deflection response of the CRFP within the quasi-static range was obtained and compared with the data existing in the literature. This provided validation of the model at the global scale. The outputs resulting from the global model were then used to develop a simulation model capturing the micro-meso scale material features. The sub-model consisted of a refined mesh representative volume element (RVE) modelled in texgen software, which was later embedded with cohesive elements in the finite element software environment. The results obtained from the developed strategy were successful in predicting the overall load-deflection response and the damage in global and sub-model at the flexure limit of the specimen. Detailed analysis of the effects of the micro-scale features was carried out. <p class="card-text"><strong>Keywords:</strong> <a
