Textile construction is well known for having a significant effect on the ballistic response of fabrics. One possible mechanism for this effect is the change in yarn-yarn interaction with changes in weave geometry. During an impact event, strain waves propagate through both fill and warp yarns. Energy transfer from warp to fill yarns and fill to warp yarns is a phenomenon that has been largely ...

Various applications of multiwalled carbon nanotubes (MWCNT) have been developed. One of these applications is an efficient sheet heating element that is woven from MWCNT-coated yarn. In this research, we assessed the exposure to MWCNT and/or the probability of particle release from broken MWCNT-coated yarn during the weaving process. This was accomplished using particle concentrations, microsc...

Most practical textile models are based on a two scale approach: a one-dimensional fiber model and a fabric model, see [1]. No meso-level is used in between, i.e. the yarn scale is neglected in this setup. For dense textile substrates this seems appropriate as the yarns connect everywhere, but for loose fabrics or scrims this approach cannot be kept. Specifically when one is interested in track...

Mohair from Angora goats has been produced in the United States since the introduction of these animals from Turkey in 1849. Cashmere on Texas meat goats was reported in 1973, but domestic interest in commercial production did not occur until the mid-1980s. Since 1982, the average prices of U.S.-produced mohair and cashmere (de-haired) have ranged from $1.81 to $9.48/kg and approximately $55 to...

Introduction We have previously reported downsizing ancient twistbased spinning technology for making continuous, densified nanotube yarns from multi-walled carbon nanotube (MWNT) forests [1]. Such nanotube yarns provide unique properties and property combinations. Despite this important progress, the relationship between nanotube yarn properties and component carbon nanotube properties is not ...

We investigated the actual factor determining the softening effect of a fabric softener. The adsorption area of the softener on model cotton cloths and yarns was identified using bromophenol blue. There was almost no softener at the cross-points of the yarns in the cloth samples or in the inner part of the yarns. The softening performance was better when there was less softener at the cross-poi...

Textile fabrics are highly anisotropic, so that their mechanical properties including strengths are a function of direction. An extreme case is when a woven fabric sample is cut in such a way where the bias angle and hence the tension loading direction is around 45° relative to the principal directions. Then, once loaded, no yarn in the sample is held at both ends, so the yarns have to build up...

Elastane fibres show rubber like behavior and are highly stretchable. Basically these fibres contain polyurethane bonds. Elastic fabrics are an important route to achieve comfort by freedom of movement for body fitted with sports and outdoor wear. Elastic garments used in athletics and sports may improve the athlete’s performance in cycling, swimming and so on. A great deal of research is repor...
