Preparation method for colored cotton thermal fabric

Abstract

The invention relates to the technical field of textiles, in particular to a preparation method for a colored cotton thermal fabric. The preparation method comprises the following steps: pre-treating colored cotton grey cloth to remove part of pectin and wax which cover the fiber surface of the colored cotton grey cloth; performing enzyme treatment on the pre-treated colored cotton grey cloth to further remove the pectin and the wax which cover the fiber surface of the colored cotton grey cloth; taking the treated colored cotton grey cloth as an inner layer and a surface layer of the colored cotton thermal fabric, and filling the space between the inner layer and the surface layer with milk fiber cotton to obtain the colored cotton thermal fabric. According to the preparation method provided by the invention, the colored cotton is used as the surface layer and inner layer of the thermal fabric, so that compared with used white cotton, the processing steps are reduced, the energy consumption is reduced, and the production cost is reduced; moreover, the colored cotton as the surface layer and the inner layer is treated, so that the ventilation property and the productwearability are improved on the basis of not influencing the warmth retention ratio of the thermal fabric.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for preparing a colored cotton warm-keeping fabric. Background technique [0002] With the continuous development of my country's market economy and the continuous improvement of people's living standards, my country's textile industry, especially thermal underwear, has made great progress. Now thermal underwear products have developed from a small-scale regional industry to a new pillar category in the national knitting industry. Such as the era of diversified products with higher technological content, this is the direction for knitted thermal underwear to enter the 21st century, and can truly meet human consumption requirements for knitted thermal underwear. [0003] At present, the inner layer and the outer layer of thermal fabrics are made of white cotton. During the dyeing and finishing process, the white cotton fabric has to undergo desizing, scouring, bleaching...

AI Technical Summary

Problems solved by technology

In the whole processing process, a large amount of water, electricity and other resources are required, the energy consumption is serious, and a large amount of waste liquid is generated, which seriously pollutes the environment.

From the perspective of textile ecology research, it does not meet the current green environmental protection requirements
