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.
Highlights
The absorption and diffusion of sweat by fabrics directly affects the comfort performance of fabric, especially sports fabrics
Knitted fabric has a soft feel, greater extensibility, and elasticity, so it has been widely used in the field of clothing
Some research has been done on the moisture management performance of fabrics
Summary
The absorption and diffusion of sweat by fabrics directly affects the comfort performance of fabric, especially sports fabrics. With the increasing popularity of the concept of public fitness exercise, people put forward higher requirements for the comfort and functionality of sportswear.[1] Especially in summer, the human body will excrete a lot of sweat due to exercise. If the sweat cannot be excreted in time, the clothes will be wetted after sweating, making the human body feel uncomfortable, and easy to breed bacteria.[2] the moisture management performance of the fabric is an important index to measure its thermal and moisture comfort. The structure of knitted fabrics is an important factor affecting the moisture management performance of fabrics. The commonly used method to enhance the moisture management performance of fabrics is to fabricating double-layer fabrics with a gradient of wettability on the inner and outer surfaces.[10,11,12] Besides, yarn linear density, loop length, and fabric thickness are important factors for the development of a good moisture management function.[13,14,15]
