Abstract

Contact force between fibers in different scales, such as microfiber and nanofiber, is different with those in the same scale. In this work, based on an electrospinning nanofiber yarn system, three different nanofiber core-spun yarns were produced and a novel experiment was designed to investigate contact force between the nanofiber layer and microfiber layer. Yarn properties, including fiber polarity, hairiness and surface area, and their impact on contact force were analyzed. Wetting performance of nanofiber core-spun yarns and their fabrics was also examined. The results demonstrated that wicking height, water evaporation rate, and moisture management ability were enhanced by the addition of nanofiber layer. Consequently, the wise experimental strategy would be valuable for the analysis of contact force within these nanofiber core- spun yarns, which exhibited potential applications in moisture wicking function and wet comfort

摘要

不同尺度的纤维，如超细纤维和纳米纤维之间的接触力与相同尺度的纤维之间的接触力是不同的。在这项工作中，基于静电纺纳米纤维纱线系统，生产了三种不同的纳米纤维包芯纱，并设计了一个新的实验来研究纳米纤维层和微纤维层之间的接触力。分析了纱线特性，包括纤维极性、毛羽和表面积，以及它们对接触力的影响。还检查了纳米纤维包芯纱及其织物的润湿性能。结果表明，纳米纤维层的加入提高了芯吸高度、水分蒸发率和水分管理能力。因此，明智的实验策略对于分析这些纳米纤维包芯纱内的接触力是有价值的，
