Preparation and moisture management performance of double guide bar warp-knitted fabric based on special covering structure

Abstract

This article provides a knitting method for warp-knitted fabrics with good moisture management performance. By adjusting of the warp knitting machine (mainly the bar), the design of lay-up method of the yarn, the selection of the yarn, and the warp let-off tension, the yarn covering relationship has been adjusted. By using two kinds of fineness polyester DTY, cotton yarn and spandex, designing two kinds of warp-knitting structures, six different warp-knitted fabrics have been knitted. The moisture management performance of these knitted samples was compared and evaluated. The study found that the greater the difference between the inner yarn and the outer yarn, the better the moisture management ability of the fabric. Polyester DTY with 50D/14F on the inner side and polyester DTY with 75D/288F on the outer side have the best moisture management performance. The polyester DTY with 50D/14F on the inside and 9.83Tex cotton yarn on the outside have higher wetting time and absorption rate.
