Contact force within electrospun nanofiber core-spun yarns and moisture management ability of their fabrics

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
