Embodiment 1

[0043] The preparation method of the hot and humid comfortable knitted fabric is as follows:

[0044] (1) Preparation of self-curling elastic fibers:

[0045] (1.1) Self-curling elastic fibers are extruded on the same spinneret, specifically:

[0046] The PET melt is divided into two paths: one path is directly extruded after distribution; the other path is extruded after being distributed with the CDP melt in a parallel composite spinning mode; the spinneret hole m (three lobe shape spinneret hole) and the ratio of the number of spinneret holes n (circular spinneret holes) that are extruded and flowed through after being distributed by the parallel composite spinning mode is 1:7;

[0047] The mass ratio of PET melt (intrinsic viscosity 0.55dL / g) to CDP melt (intrinsic viscosity 0.75dL / g) passing through spinneret n is 50:50, spinneret m and spinneret n The ratio of equivalent diameter is 1:1;

Abstract

The invention relates to thermal-wet comfortable knitted fabric and a preparation method thereof. The thermal-wet comfortable knitted fabric is prepared by taking viscose fibers as surface yarn raw materials, self-curling elastic fibers and viscose fibers as intermediate yarn raw materials and cross-shaped PET fibers and viscose fibers as ground yarn raw materials, performing three-thread plaitingknitting and carrying out finishing; and the self-curling elastic fibers are prepared according to an FDY process: dividing a PET melt into two paths: one path is directly extruded after being distributed, and the other path and a CDP melt are distributed together according to a parallel composite spinning mode and then extruded. The thermal-wet comfortable knitted fabric provided by the invention does not have the problem of ''strip-shaped unevenness'', the washing size change rates of the thermal-wet comfortable knitted fabric in the warp direction and the weft direction are between -1.0% and 1.0%, the water absorption rate of the thermal-wet comfortable knitted fabric is greater than or equal to 280%, the drip diffusion time is less than or equal to 2.1 seconds, the wicking height is greater than or equal to 140mm, the evaporation rate is greater than or equal to 0.32g / h, and the moisture permeability is greater than or equal to 127000g / (m2d).

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and relates to a heat-humidity comfortable knitted fabric and a preparation method thereof. Background technique [0002] The comfort of textiles is divided into several aspects, such as heat and moisture comfort, pressure comfort, contact comfort, psychological comfort and physiological comfort, and they each have their own importance and complement each other. Heat and moisture comfort refers to the fact that textiles maintain a constant body temperature between the heat and moisture transfer between people and the environment, providing good conditions for the normal physiological functions of the human body, so that the human body maintains a comfortable feeling. It is of great practical significance to develop thermal and moisture comfortable fabrics. [0003] In the big family of two-component composite fibers, the side-by-side two-component composite fiber is an important member. ...
