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;

[0048] In the three-lobed spinneret hole, the three leaves are respectively lea...

Abstract

The invention relates to a warm and comfortable knitted fabric and a preparation method thereof. Viscose fiber is used as the raw material of the veil, self-curling elastic fiber and viscose fiber are used as the raw material of the intermediate yarn, and cross-shaped PET fiber and viscose fiber are used as the ground yarn Raw material, weaving with three-thread plating and finishing to obtain hot and humid comfortable knitted fabric; self-crimping elastic fiber is produced by FDY process: the PET melt is divided into two paths: one path is directly extruded after distribution, and the other path is mixed with CDP The melts are distributed together by parallel composite spinning and then extruded. The heat-humidity comfortable knitted fabric of the present invention does not have the problem of "uneven strips", and the washing dimensional change rate of the heat-humidity comfortable knitted fabric in the warp direction and weft direction is between -1.0% to 1.0%. The water absorption rate of comfortable knitted fabrics is ≥280%, the drip diffusion time is ≤2.1 seconds, the wicking height is ≥140mm, the evaporation rate is ≥0.32g / h, and the moisture permeability is ≥127000g / (m 2 d).

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. ...
