Fabric sensory properties are complex concepts which include dimensional changes at small forces such as tensile, shear, compression and bending, surface properties (friction and roughness) plus surface coolness or warmness. The aim of this study was to investigating the effect of weft yarn twist level on sensorial comfort of 100% woven cotton fabrics. Five cotton fabrics were woven with incremental weft yarn twist levels and their tensile and shear strength, pure bending, compression, surface friction and roughness were evaluated using Kawabata Evaluation System and compared. The other sample parameters such as count, thread density and fabric structure were kept constant. Fabric water permeability and its wicking ability were also evaluated. The results showed that as the twist level increased, the fabric tensile, shear and bending properties also increased. This was observed in both the warp and weft direction. At higher level of twist, lower surface friction, less compressibility, less slipperiness (0.264 warp and 0.199 weft direction), rougher surface (0.026 warp and 0.020 weft) and less even surface (2.643 warp and 1.998) were observed. The wicking ability also reduced with the increase in twist level while there was an improvement in water permeability.

纬纱捻度对100％棉织物机械和感官舒适性的影响

织物的感官特性是复杂的概念，包括在较小的力（例如拉伸力，剪切力，压缩力和弯曲力）下的尺寸变化，表面特性（摩擦和粗糙度）以及表面的凉爽或温暖。这项研究的目的是调查纬纱加捻水平对100％机织棉织物的感官舒适性的影响。五种棉织物以增加的纬纱捻度编织，并使用Kawabata评估系统评估其拉伸强度和剪切强度，纯弯曲性，压缩性，表面摩擦性和粗糙度，并进行比较。其他样品参数（例如支数，线密度和织物结构）保持恒定。还评估了织物的透水性及其芯吸能力。结果表明，随着捻度的增加，织物的拉伸，剪切和弯曲性能也增加了。在经向和纬向都可以观察到这一点。在较高的捻度下，观察到较低的表面摩擦，较低的可压缩性，较低的滑爽度（0.264经线和0.199纬向），较粗糙的表面（0.026经线和0.020纬向）和较不平坦的表面（2.643经线和1.998）。芯吸能力也随着捻度的增加而降低，同时透水性得到改善。
