The penetration behavior of Kevlar fabric intercalated with dry particles and shear thickening fluids (STF), highly concentrated fluid-particle suspensions, is presented. In particular, the role of particle hardness is explored by comparing fabric treatments containing SiO(2) particles, which are significantly harder than Kevlar, to treatments containing softer poly(methyl methacrylate) (PMMA) ...

The chemical recycling of hemp fabric into high-tenacity man-made cellulose fibers was demonstrated. laundered 25 and 50 times to mimic the wear cycles post-consumer textile waste. Despite launderings, molar mass material still too high for via dry-jet-wet spinning. Thus, fabrics were treated with an aqueous sulfuric acid solution adjust intrinsic viscosity targeted level 400–500 ml/g. hydrolyz...

The effect of material type, yarn count, pick density, type of mordant and layers of fabrics on the electromagnetic shielding properties of textile materials has been studied. The shielding effectiveness of the fabric is measured by estimating the insertion loss incurred to the signal when the sample is placed in the path of the signal at the frequency range 100 MHz-3 GHz inside the coaxial tra...

Abstract This study aims to investigate the energy absorption of seam areas in sportswear. Weft knitted fabrics with two structures plain and rib were fabricated by polyester/Lycra viscose/ Lycra yarns. Fabrics stitched stitch classes. Moreover, types seams considered. A pull-out test was carried out on all samples determine values. Furthermore, a finite element model applied predict each struc...

Exploring the effect of tuck loops on fabric properties some knitted structures was aimed in this study. Samples were produced a Stoll V-bed knitting loom with 100% acrylic yarn. Five types knit (1x1 rib, half cardigan, double cardigan and cardigan) identical machine settings. Test results revealed that has highest thickness, thermal resistance coefficient friction. Double provides air permeabi...

In industrial textile pre-treatment and finishing processes, mass transfer and mass transport are often rate-limiting. As a result, these processes require a relatively long residence time, large amounts of water and chemicals, and are also energy-consuming. In most of these processes, diffusion and convection in the inter-yarn and intra-yarn pores of the fabric are the limiting mass transport ...

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 ...

Most softening agents, such as rinse cycle fabric softeners, used by consumers at home contain cationic surfactants that have two long alkyl chains as their main component. The softening mechanism on fibers, especially cotton, has not yet been scientifically established, despite the market prevalence of fabric softeners for decades. One explanation for the softening effect is that the friction ...

In this article a practical mass-spring system was developed to simulate the draping of woven and knitted fabrics. The material properties important to fabric drape, including aerial density, tensile, shear, and bending properties were measured using the Kawabata Evaluation System and the experimental data were incorporated into the mass-spring model to simulate the dynamic draping behavior of ...
