Embodiment 1

[0044] The preparation method of sports knitted fabric, its process is as follows:

[0045] (1) Preparation of self-curling elastic fibers:

[0046] (1.1) Self-curling elastic fibers are extruded on the same spinneret, specifically:

[0047] Divide CDP melt (intrinsic viscosity 0.6dL / g) into two paths: one path is directly extruded after distribution; the other path is distributed with PTT melt (intrinsic viscosity 1.1dL / g) in parallel composite spinning squeeze out

[0048] The ratio between the number of spinneret holes m (four-lobed spinneret holes) that are directly extruded and flowed through and the number of spinneret holes n (circular spinneret holes) that are extruded and flowed through after distribution according to the parallel composite spinning method The ratio is 1:7; the mass ratio of the mass of the CDP melt passing through the spinneret n to the mass of the PTT melt is 50:50, and the ratio of the equivalent diameter of the spinneret m to the spinneret n is ...

Abstract

The invention relates to a sports type knitted fabric and a preparation method thereof. Cotton fibers are taken as a surface yarn raw material, self-curling elastic fibers are taken as an intermediateyarn raw material, fine-denier cruciform PET fibers are taken as a ground yarn raw material, three-wire adding yarn weaving and finishing are carried out, and the sports type knitted fabric is prepared; the self-curling elastic are prepared according to an FDY process, and a CDP melt is split into two paths, wherein one path is directly extruded after being dispensed, and the other path is extruded after being distributed in a parallel composite spinning mode along with the PTT melt. The sports type knitted fabric prepared by the invention does not have the problem of non-uniform strip-like shape, and the gram weight of the sports type knitted fabric is 120-160 g/m2. The rate of change of the washing size in the warp direction and the weft direction is between -1.0% and 1.0%, the water absorption rate of the sports type knitted fabric is greater than or equal to 275%, the drip diffusion time is less than or equal to 2.2 seconds, the wicking height is greater than or equal to 142 mm, and the evaporation rate is greater than or equal to 0.33g/h , and the moisture permeability is greater than or equal to 128000 g/(m2.d).

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and relates to a sports knitted fabric and a preparation method thereof. Background technique [0002] Today's consumers place ever higher demands on the comfort and functionality of textiles. For spring and summer clothes, it is desired to be light, breathable and comfortable; for autumn and winter clothes, it is required to have good warmth retention. For sporty clothes, it is hoped that it only has a good moisture absorption and perspiration function, while traditional fabrics cannot meet the needs of consumers. Thereby developing sports fabric is of great practical significance. Sports moisture-wicking fabrics are mainly suitable for use in environments with a lot of exercise, sweating and hot weather. Generally, the sweat on the surface of the human body is conducted outward through close-fitting sportswear to keep the skin dry and comfortable. [0003] In the big family of two-co...
