Research on plated structure design in weft knitting seamless fabric and sweat management

Abstract

During exercise, the degree of sweating in different parts of the body varies. The organization of different functions in different parts can be realized using weft knitting seamless technology. The advantage of this technology was that it can be one-piece woven, has high efficiency, offers environmental protection, provides superior wearing comfort, and facilitates the rapid response of sweat and sweat management in different parts. In this work, 9.33 tex/384 F yarn was selected as the face yarn, and 5.55 tex/24 F yarn was selected as the ground yarn, seven fabrics were designed using a combination of three basic plated loops. The effect of two factors, surface porosity and fabric tightness, on the sweat management performance of plated fabrics was investigated through experiments, including moisture management performance, liquid spreading performance, wicking performance, evaporation performance, air permeability and moisture permeability performance, etc. The results showed that the smaller the surface porosity of the fabric, the better the one-way transmission performance of the liquid. However, the larger the surface porosity, the easier the liquid plane diffusion was. The tightness of the yarn filling in the fabric was beneficial for the weft flow of the liquid. A certain degree of tightness was helpful for the unidirectional conduction of fluid, but both too tight and too loose fabrics were not conducive to fluid conduction. Studying the difference in performance caused by the surface porosity and the tightness of the fabric can provide some theoretical help for the design of weft-knit seamless sports products.
