Currently the abrasion and breakage of warp during the weaving process have become the key issue in high-speed weaving of non-shuttle looms. According to the experiment, the heald frame is the main zone where warp abrades. With the multiple effects of shedding and beating up, warp will make a frictional movement every time one weft is weaved, no matter which opening mode is used. These frequent frictional movements will cause warp's surface damage, which leads to breakage. Therefore warp's frequent frictional movement in the heald eye is the main factor causing warp's breakage. By theoretically analyzing warp's front and back elongation and tension while beating up, this paper establishes the formula of warp's movement in the heald eye, and discusses the effect of weaving parameters on this movement, such as looming tension, warp line, opening time and geometric shedding size. This provides theoretical basis for solving the frictional issue reasonably. According to the result, by forming the shed with big tension, high back-rest, late shedding, long shed, fast opening and slow closing, the frictional movement of warp in the heald eye can be reduced during the weaving process. In this way, warp's excessive abrasion can be avoided and its breakage will be lowered, so as to improve weaving efficiency. © (2011) Trans Tech Publications.

T-400 is an elastic fiber developed by Dupont. It was commended as one of the best developing prospect chemical fiber in the 21 century. In this paper, the elasticity of spun silk/T-400 interlaced fabric was studied. The elastic characteristic of the spun silk/T-400 interlaced fabric with different warp density, weft density, fabric intensity and fabric weave were tested and analyzed. And the stress relaxation was studied. It shows that elastic reversion at certain elongation of the fabric is correlative directly with the warp density, weft density, intensity and weave. The elastic reversion at certain elongation decreased following the warp density and weft density increased. And it was increased following the ratio of weft intensity to warping intensity and the fabric average float increased. The time of stress relaxation is longer if the warp density is larger. The time is shorter when the warp density and the fabric average float is larger. And the correlative curve was pictured and the correlative formula was built. © (2011) Trans Tech Publications, Switzerland.

The utilized field of polyester fabric was limited because the static can be produced easily when it was used. In this paper, the anti-static treating crafts of polyester staple fabric treated by polyaniline were probed. The raw fabric material was weaved with polyester staple yarn and the aniline was selected as anti-static reagent. The process of aniline polymerizing was analyzed and discussed. The anti-static characteristic of the finished fabric was analyzed. With systemic experimental and data analysis, the integrate process of the fabric anti-static finished by polyaniline was achieved. The result shows that the property of anti-static can be obtained if the polyester staple fabric was treated by polyaniline at the advisable processes. and the polyester fabric can be sued in widely field. © (2011) Trans Tech Publications, Switzerland.

Aging performances of polyester oxford with different weaving parameters were analyzed. Filament fineness and fabric density were key parameters. The filaments' tensile strength, the characteristic groups on the fiber surface by FTIR and the determination of terminal carboxyl group were tested, and then the changes of characteristic groups were analyzed by internal standard working curve methods. It was resulted that during the former aging, the orientation of fibers were destroyed, meanwhile the ester bonds on carboxyl decreased and ester bonds on (C-O-C) formed, and during the later aging, etching on the surface of fibers made the ester bonds sharp decreasing. Compared with different fineness, thicker fibers with one more stretch process have the higher degree of orientation, and then prolong the aging. Then compared with different fabric density, the higher density can prolong the aging, provided of no frictions harm fibers during weaving. © (2012) Trans Tech Publications, Switzerland.

In this work, we have developed a facile differential pressure route to prepare PET-based hollow fibers containing silver particles (Ag/PET hollow fibers). X-ray Diffraction and Scanning Electron Microscopy were used to confirm the existence of silver particles, and the results showed that 0.1-0.5 μm silver particles were incorporated in the inner side-wall of the hollow portion. Inductively Coupled Plasma Atomic Emission Spectrometer was applied to detect the release behavior of silver ions from various Ag/PET hollow fibers. And the results showed that the release behavior of silver ions was depended on time and the length of the fibers, which may be explained by the water uptake property of the Ag/PET hollow fibers. © 2011 Elsevier B.V.

This paper describes the use of high-count silver fiber / cotton blended yarn as raw material, to design antibacterial yarn-dyed shirting fabric. During the process of designing,the designer should take into account both antibacterial, deodorant characteristics and static electricity eliminating effect, but also consider the cost. The smart grid design of the electri-city interlacing of silver-containing fiber with cotton blended yarn and pure cotton yarn is presented as a net shape, which could improve the antibacterial features of the shirting material with the organization of small circulation. Therefore, in this paper the designing process of antibacterial yarn-dyed shirting material is put forward. © (2013) Trans Tech Publications, Switzerland.

This paper expatiates to assist high-count yarn in the use of water-soluble yarn, and then to dissolve the water-soluble fiber of the poplin grey fabric, and to get the yarn-dyed poplin shirt fabric with high-count and high-density and softness. It presents a technology process of assisting 100 s cotton yarns to produce the yarn-dyed poplin shirt fabric design with high-count and high-density and softness by using 100 s water-soluble yarns. © (2013) Trans Tech Publications, Switzerland.

Paris’ Fashion week gets underway next week and for the first time, NUMA in conjunction with Parsons Paris, Fashion Technology Lab and Fashion Capital Partners, will host the 1st Fashion & Tech week 22 – 28 September to explore the impact of new technologies on the fashion industry. More than 70 hours of events have been organized to conceptualize and co-create tomorrow’s fashion trends. From accessories to e-textiles to 3D, the week-long program will address questions such as: what are the next innovation opportunities in the sector? what shape will be the next evolutions take? how can the use of technology in the fashion world be increased, and by doing so enable new forms of creation to scale up?  and more… The multi-day event will include conferences, meet-ups, tailored talks, a fashion tech hackathon, fashion tech Startup Weekend, a Global Fashion & Tech Battle sponsored by Google for Entrepreneurs, and, even, a digital art performance.  NUMA’s 1st fashion & tech week will also put the spotlight on startups and others, such Netatmo, I am la mode, Vestiare Collective, Misfit Wearables, ICONITY and Pinterest, who are merging the worlds of fashion and tech.  As it’s Fashion Week, of course designers will be a big part of the mix as well, with rising designers like  Elisabeth de Senneville, Starkweather and more will also be on display. If you’re fashion tech startup, working in fashion or just have a passion for fashion and fashion tech, you can register to attend one or more of the events here.
