Light, thin thermal-wet comfort multifunctional knitted fabric and preparation method thereof

Abstract

The invention provides light, thin thermal-wet comfort multifunctional knitted fabric and a preparation method thereof. The fabric is formed by weaving first yarn, second yarn, third yarn and fourth yarn. The fabric is of a three-layer structure composed of an outer layer, a middle layer and an inner layer. The outer layer is formed by weaving the first yarn. The middle layer is formed by weaving the second yarn and the third yarn. The inner layer is formed by weaving the fourth yarn. The moisture-absorption and heat-generating heating up value of the fabric meets the standard requirements in the textile industry, moisture adsorption performance, quick drying performance, comprehensive sweat-discharge quick drying performance and other indexes meet values required by national standards before and after the fabric is washed, and the heat-preserving rate index meets the values required by the national standards; meanwhile, the fabric has a good moisture retention function, moisture needed by human skin is locked, and human skin aging can be effectively relieved.

Description

technical field [0001] The invention belongs to the technical field of knitted garment fabrics, and specifically refers to a light, thin, heat-humid and comfortable multifunctional knitted fabric and a preparation method thereof. Background technique [0002] People have been studying the heat and humidity comfort performance of knitted fabrics for a long time. In the past, they only stayed at the level of theoretical research. In recent years, there have been many products that improve people's heat and humidity comfort performance, but most of them are researches on unidirectional moisture-conducting fabrics and new types of moisture absorption. The research on the application of heating materials has produced some new fabrics with one-way moisture guide and moisture absorption and heat generation. The moisture absorption and perspiration function of the fabric has been improved unprecedentedly. The final wet and cold feeling can enhance the heating and warmth performance ...

AI Technical Summary

Problems solved by technology

However, the inner layer of the moisture-absorbing and heat-generating knitted fabric contains a large amount of polyester fibers. Although the special new spinning technology is adopted, the characteristics of polyester fibers that are prone to pilling and pilling cannot be changed. The anti-pilling performance is poor, and wearing for a long time will affect In addition, the delivery time and price of large-scale products are easily subject to raw material suppliers and their price monopoly position

[0005] The invention patent with application number 201410052915.7 discloses a moisture-absorbing, heat-generating, quick-drying, moisturizing and warm-keeping fabric and its preparation method. The contact with the outer layer is a point contact of one contact point, and the connection between the middle layer and the inner layer is in the form of a loop, and the contact is a point contact of two contact points, neither of which is a surface contact method covered by plating. The second yarn The wicking and moisture-wicking ability of the thread is difficult to maximize, so that although the fabric has obvious moisture-absorbing and quick-drying performance, the moisture-absorbing and quick-drying performance is still difficult to fully meet the requirements of the one-way moisture-wicking test.

In addition, the fabric has a double-sided weave structure. Under the premise of ensuring the comfort and elasticity of the fabric, the fabric cannot be made very thin, and the fabric is slightly bloated, which is difficult to meet people's requirements for lightness, thinness and warmth.
