Problems solved by technology

[0003] The antibacterial function can be achieved by adding antibacterial ingredients to the raw materials, or by performing antibacterial finishing on the fabric. For the moisture absorption and quick-drying performance, different raw material selections will have a great impact on the performance of the product. In sports knitted fabrics, more and more Chemical fibers are used. Chemical fibers have good mechanical properties, are easy to handle, have less water residue, and are easier to achieve good antibacterial effects. Among them, hydrophobic chemical fibers with special-shaped cross-sections are the most widely used, and their moisture absorption and quick-drying properties are better than those of circular cross-section fibers. It is better, but the grooves of general special-shaped cross-section fibers are on the same side, and the efficiency of moisture conduction needs to be further improved

Abstract

The invention relates to a preparation method of a sports knitted fabric. After yarn a and yarn b are interwoven into a gray fabric, compound finishing and relaxation heat treatment are carried out in sequence to obtain a sports knitted fabric; the yarn a is made of a polyester fiber with a circular cross section. Composition, yarn b is composed of special-shaped fibers; the preparation process of special-shaped fibers is: according to the FDY process, after the high-viscosity CDP melt and the low-viscosity CDP melt are distributed, they are extruded from the spinneret holes on the same spinneret FDY filaments, that is, special-shaped fibers; the spinneret holes are shaped spinneret holes, which are composed of horizontal lines and vertical lines I and II vertically connected to them; distribution refers to controlling the flow of high-viscosity CDP melt through the horizontal lines, and at the same time The low viscosity CDP melt is controlled to flow through vertical line I and vertical line II. The invention adopts a simple preparation method to prepare twisted fiber which is beneficial to water export, and further obtains a moisture-absorbing and quick-drying sports knitted fabric.

Description

technical field [0001] The invention belongs to the field of fiber technology and relates to a preparation method of sports knitted fabrics. Background technique [0002] In recent years, with the promotion and widespread popularity of sports around the world, people not only increase the demand for sportswear, but also put forward higher requirements for the wearing comfort and health care functions of sportswear. Since exercise is prone to sweating and bacteria breeding, it affects the health of the body. Therefore, moisture absorption, quick drying and antibacterial properties have gradually become essential properties of sportswear. [0003] The antibacterial function can be achieved by adding antibacterial ingredients to the raw materials, or by performing antibacterial finishing on the fabric. For the moisture absorption and quick-drying performance, different raw material selections will have a great impact on the performance of the product. In sports knitted fabrics,...
