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. The preparation method comprises the steps of interweaving yarns a and b into grey cloth, and then sequentially performing composite finishing and relaxation heat treatment to obtain the sports knitted fabric, wherein the yarn a is composed of polyester fibers with a circular cross section, and the yarn b is composed of profiled fibers; the preparation process of the profiled fiber comprises the following steps of distributing the high-viscosity CDP melt and the low-viscosity CDP melt according to a FDY process, and extruding from spinneret orifices on the same spinneret plate to prepare FDY filaments, namely profiled fibers, wherein the spinneret orifice is the spinneret orifice in a shape as shown in description, the shape as shown in description is composed of transverse line and a vertical line I and a vertical line II which are vertically connected with the transverse line; the distribution means controllingthe high-viscosity CDP melt to flow through the transverse line, and controlling the low-viscosity CDP melt to flow through the vertical line I and the vertical line II. A simple preparation method is used for preparing the fiber with twisted shape which is beneficial to the water export, thereby preparing the 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,...
