Heat and sweat regulating performance of zoning structure weft-knitted sportswear

In this study, weft-knitted seamless technology was used to configure different structures in different positions of sportswear to realize the regulation of heat and moisture partition of the human body. Six kinds of weft-knitted fabric with different structures were designed by using super-fine polyester functional yarn as face yarn and ground yarn of different raw materials. We studied the effects of the types of ground yarns and fabric structures on the thermal and wet comfort of fabrics. According to the comprehensive evaluation of fabric and the difference of sweat in different parts of the human body, the clothing with zoning structure was designed and tested. The experiment showed that fabric made of 55 dtex polyester with 14 single fibers combined with 93.3 dtex polyester with 384 single fibers exhibited excellent moisture management properties. Compared with 55.5 dtex nylon/22.2 dtex spandex covered yarn, the combination of 55.5 dtex polyester/22.2 dtex spandex covered yarn and 93.3 dtex/384 f polyester yarn had superior performance. In the process of zone clothing, the temperature inside decreases and sweat accumulates less. However, the temperature of the inner side of the clothing on the market rises and the humidity accumulates obviously during exercise, which shows that the zone structure can respond to the heat and moisture change of different parts more effectively.
