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...

Modeling the 3D geometric configuration of yarn is the base of building the 3D fabric structure. The surfaces of the yarns are modeled by many facets. To improve the efficiency of modeling, 3D yarn is usually designed by Bezier curve, spline curve or B-spline curve on the principle of Computer Graphics. The paper reviews different 3D modeling methods for single yarn from the view of cross-secti...

In recent years, continuous fiber-reinforced thermoplastic composites have attracted attention for their high mechanical properties, secondary workability, and recyclability. However, it is not easy to impregnate resin into reinforcing fiber bundles because the melt viscosity of before curing higher than that thermosetting resin. One methods solve this problem use intermediate materials, study ...

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...

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...

In this study, a novel triboelectric device is developed that consists of silicone-coated conductive yarn and PET film as active substances, an elastic spacer force controller. The prepared by applying thermally curable silicone to yarns using simple but continuous method. made 20 cm long can generate peak voltage high 225 V current outputs 2.4 µA. functions maintain the in separate state when ...

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...

We studied the effects ion beam irradiation on carbon nanotube (CNT) yarns. CNT yarn was fabricated by drawing and spinning CNT sheets from a vertically aligned CNT forest. The yarn was irradiated by 2.5 MeV protons in either vacuum or air. Irradiation in air was achieved by directing the proton beam through a 0.025 mm thick Ti window. Irradiation in vacuum occurred at a pressure of <10-6 torr ...

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...
