Indeed, it is nowadays necessary for car industry to promote ecological methods of development in regard to new consumer sensibility. New textile products present the best alternative solutions to answer this issue of replacement of the PU foam. Based on this fact, a new three-dimensional (3D) fibrous structure made of polyester (PET) material has been developed in order to replace PU foam in automotive trim. These new manufactured 3D fibrous structures are laminated with needle-punched and spun-bonded sheets. The sheets are made of 100% PET, in order to obtain a mono component product. Characterization of physical and mechanical properties of these new 3D fibrous structures, testing methods have to be developed. Based on the automotive specifications, a methodology has been set up to test the compression behavior of these new products. In order to answer the issue of replacement, some PU foam products have also been characterized, and comparisons with alternative products have been conducted. The results of this study show interesting properties of the new 3D fibrous structure in terms of compression behavior when compared to the PU foam.","PeriodicalId":49978,"journal":{"name":"Journal of the Textile Institute","volume":"104 1","pages":"1237 - 1246"},"PeriodicalIF":1.7,"publicationDate":"2013-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/00405000.2013.796084","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58871318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present paper, the hybrid fabrics in plain and rib structures were knitted by using single and double ply hybrid yarns obtained by acrylic (PAC) yarns plied with stainless steel wires having two different diameters. The physical properties including conductivity, air permeability, pilling, and abrasion resistance as well as electromagnetic shielding effectiveness (EMSE) were measured. The variations in EMSE as well as reflection, absorption, and transmission and in other physical properties of knitted hybrid fabrics were investigated considering wire content and weave structure. It was seen that an increase in the wire content significantly increased the conductivity. Rib fabrics exhibited better EMSE values as compared with plain fabrics. Fabrics using two-folded yarns exhibited better EMSE values. Fabrics using thinner wire exhibited higher EMSE values. The highest EMSE value was obtained for rib-knitted fabric with 35 micrometer (μm) stainless steel wire.","PeriodicalId":49978,"journal":{"name":"Journal of the Textile Institute","volume":"104 1","pages":"1247 - 1257"},"PeriodicalIF":1.7,"publicationDate":"2013-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/00405000.2013.796627","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58871332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conformational changes of lipase after the heat treatment were studied by both Fluorescence spectra test and UV spectra test. The UV values (as the unfolding ratios of lipase) calculated from UV spectra were related to the proportion of inactivated lipase. Residual activityUV (originated from UV values) reflected residual lipase activity from the experimental data accurately. Compared with cotton fabrics treated by the crude lipase at 75°C, the appearance of polyols enhanced the capillary effect and weight loss of cotton fabrics to some extent.","PeriodicalId":49978,"journal":{"name":"Journal of the Textile Institute","volume":"104 1","pages":"1206 - 1212"},"PeriodicalIF":1.7,"publicationDate":"2013-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/00405000.2013.787240","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58871177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the finite element analysis model, a microstructure shell element model of the woven composite at yarn level was established to calculate the fatigue behaviors and stress distribution during cyclic loading. The stress distributions in the warp, weft yarns, and the resin regions have been calculated to show the stress difference in the woven composite. It has been observed that the warp yarns share the most part of the stress or loading, i.e. the strength warp yarn is more important than that of the weft yarn for the fatigue design. In addition, the stress distributions at the locations where the weft yarns crossover the warp yarns have been investigated. The stress degradations of the top and bottom surface of the woven composite panels were also compared with those in experimental and good agreement was found. With the stress distribution in the woven composite, the method of improving the fatigue damage tolerance was expected to be developed.","PeriodicalId":49978,"journal":{"name":"Journal of the Textile Institute","volume":"104 1","pages":"1186 - 1194"},"PeriodicalIF":1.7,"publicationDate":"2013-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/00405000.2013.785080","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58871110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is determined that the increase in the fabric tightness decreases the air permeability and increases the wicking ability especially in 60 min measurements.

In this study, at first, fabrics were woven with two types of design (plain and twill) and four different thread densities. Then, they were compounded into fine-grained concrete as a beam. After 4 weeks, the bending properties of all the samples were tested using four-point bending test method. The bending properties of these composite samples were evaluated using different parameters including the load at the elastic zone (limit of proportionality [LOP]) as well as the highest-peak point (modulus of rupture), toughness values, and toughness indices at the specific deflections. New parameters namely: toughness value and toughness index at the highest-peak point were also suggested in this study. The results showed that the bending load of concrete beams reinforced with plain fabric at the elastic region (LOP point) is identical to that of simple concrete beam whereas concrete beams reinforced with twill fabric exhibited lower value. Also, increasing thread density increased the bending load at the composite failure point while the effect of weave design was not significant. It is also indicated that the toughness properties of concrete composite beams have been improved with a denser carbon/polypropylene fabric particularly at higher bending deflections whereas the weave design did not show any significant effect and only influenced on toughness properties at small deflection values. The obtained results of this work suggest that concrete composite beams reinforced with carbon/polypropylene woven fabrics on average are 6.5–40.75 times tougher than simple concrete beams.","PeriodicalId":49978,"journal":{"name":"Journal of the Textile Institute","volume":"104 1","pages":"1213 - 1220"},"PeriodicalIF":1.7,"publicationDate":"2013-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/00405000.2013.787269","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58871196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Upsdell","doi":"10.1080/00405000.2013.786252","DOIUrl":"https://doi.org/10.1080/00405000.2013.786252","url":null,"abstract":"Research has shown a technical description of a blend for most woollen carpet applications can be met with objective measurements, namely mean fibre diameter, fibre length after carding, wool bulk, proportion of medullation, base colour and vegetable matter content. The compressional property of wool as reflected in bulk is strongly related to mean fibre diameter and mean fibre curvature. Both these measurements can now be measured simultaneously with recently developed electronic instrumentation. While the processing implications of changes in mean fibre diameter are well understood, the processing implications of changes in objectively measured mean fibre curvature have not been investigated in detail. A total of 360 New Zealand Romcross type fleeces shorn from yearling sheep, with an individual range in mean fibre diameter of 23.2–40.6 μm and an individual range in mean fibre curvature of 34–115°/mm were used. The individual fleeces were sorted to create five, similar-sized, wool-processing lines with the following specifications for mean fibre diameter and mean fibre curvature. Lot 1: low fibre diameter/high fibre curvature (30.2 μm, 72°/mm); Lot 2: high fibre diameter/high fibre curvature (33.5 μm, 70°/mm); Lot 3: medium fibre diameter/medium fibre curvature (32.1 μm, 64°/mm); Lot 4: low fibre diameter/low fibre curvature (31.1 μm, 58°/mm); and Lot 5: high fibre diameter/low fibre curvature (34.5 μm, 51°/mm). Each processing lot was scoured, combed to reduce the proportion of short fibre within each lot and spun into yarn on the semi-worsted system. Mean spindle speed at break (50 fibres in cross-section) and yarn breaking load were greatest for Lot 4 and lowest for Lot 2. Increasing fibre diameter and increasing fibre curvature resulted in less unevenness within the yarn and a decrease in neps. Coarse highly crimped fibre produced the bulkiest yarn while the finer straighter fibre produced the lowest bulk yarn. Potential wearability of knitted garments using yarn spun from each processing lot was assessed using standard knitted squares. Increasing fibre diameter and increasing fibre curvature resulted in greater relaxation shrinkage in length, while decreasing fibre diameter and increasing fibre curvature resulted in increased extensibility in width. Overall resistance to felting shrinkage increased as crimp and diameter increased. There was no difference in pilling between the processing lots. The presented results indicate that increasing fibre curvature in Romcross type sheep as may occur through selection or crossbreeding associated with improving lamb production, will have a beneficial effect on the performance of products made from their wool.","PeriodicalId":49978,"journal":{"name":"Journal of the Textile Institute","volume":"104 1","pages":"1195 - 1205"},"PeriodicalIF":1.7,"publicationDate":"2013-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/00405000.2013.786252","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58871122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yarn breaking is due to fiber breakages and fiber’s slippages. In reality, a part of the fibers slip while the other part breaks. In this study, we have shown that fatigue yarn, resulting in a fundamental way impact on the number of breaks on the weaving machine, and sometimes on the physical properties of fabrics. Given the importance of the issue and the very limited directed research number in this direction, a tests series were carried out with the aim to highlight the changes to the physical characteristics of the yarn resulting from mechanical treatment comparable to that which they are subjected on the weaving machine. In the first part of our investigation, the residual deformation, tensile strength, and elongation at break of combed and carded threads were measured. In the second part, the influence of the extensions number, their amplitudes, and frequencies were analyzed. In order to examine the influence of these parameters, carded and combed yarns, with different characteristics were prepared. Therefore, based on the separate treatment results of three test series, it appears that: the warp yarns subjected to repeated extensions undergo the phenomenon of fatigue. Yarns fatigue reduces their elasticity and resistance and it is the cause for break yarn during weaving. The fatigue of wool yarns is very low compared to other textile materials.","PeriodicalId":49978,"journal":{"name":"Journal of the Textile Institute","volume":"104 1","pages":"1156 - 1163"},"PeriodicalIF":1.7,"publicationDate":"2013-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/00405000.2013.779057","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58871052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
