Anti-permeability and moisture absorption different-function knitted fabric and production process thereof

Abstract

The invention discloses an anti-permeability and moisture absorption different-function knitted fabric and a production process thereof. The anti-permeability and moisture absorption different-function knitted fabric is of a double-layer structure, a middle connection tuck is connected between the outer layer and the inner layer, the outer layer and the middle connection tuck are made of water-repellency terylene subjected to surface modification processing, and the inner layer is made of terylene with irregular sections and having moisture absorption and sweat releasing functions. The production process of the anti-permeability and moisture absorption different-function knitted fabric includes steps of performing weaving to obtain grey fabric according to the double-layer textile design; performing preprocessing, dyeing, softening, dewatering and wet cutting for the grey fabric; and performing after finishing through a setting machine. According to the anti-permeability and moisture absorption different-function knitted fabric and the production process thereof, two different functions are combined in the inner layer and the outer layer of the fabric, and requirements of sports knitwear for combining inner layer moisture absorption and sweat releasing functions with outer layer sweat stain prevention function are met.

Description

technical field [0001] The invention belongs to the field of textiles, and relates to a knitted fabric with different functions of anti-permeability and moisture absorption and a manufacturing process thereof. Background technique [0002] With the rapid development of various functional fabrics, knitted garments have also produced more and more functional requirements, and have developed from a single function to a multi-functional composite direction. Multi-layer fabrics with different functions first appeared as multi-layer laminated coated fabrics used in energy batteries, while warp-knitted shoe fabrics appeared at the end of the last century for textile fabrics, and now the most widely used is three-layer knitted mesh fabrics , also known as "sandwich mesh". With the increasing demand for double-sided functional fabrics in the market, in recent years, there have appeared such as one side moisture absorption and one side water repellency, one side hardening and one sid...

Problems solved by technology

[0005] The Chinese invention patent with the application number of 201110026818.7 discloses a water-repellent, anti-fouling, moisture-absorbing and sweat-wicking composite knitted fabric and its production method. It is greatly affected by the number of washings, and the durability is not good; the middle connecting layer coil is made of cotton, wool, silk or hemp yarn with good water absorption and hygroscopicity, so that the sweat absorbed by the inner layer coil will be conducted to the middle connecting layer coil. If the fabric is used in sportswear, sweat stains will still appear on the outer surface of the fabric, which is not beautiful; it uses three kinds of yarns to weave double-layer composite structure of double rib, and the density ratio of the outer layer and the inner layer is 2:1 , resulting in a high surface density of the fabric, which is not conducive to ventilation, and the fabric will feel stiff and thick, and the wearing comfort is poor; the production method is to weave the three kinds of yarns into gray fabrics through different yarn dyeing and functional finishing. Finished fabrics are produced after washing and shaping. The processing technology is complex, the process is cumbersome, and the production cost is high. In actual production, most factories do not use this method for production, and it is difficult to realize industrialization; the three kinds of yarns used are all dyed and finished. After weaving and high-temperature dyeing, the water-repellent effect and moisture-wicking effect of the yarn will inevitably be affected. At the same time, it is not possible to add moisture-absorbing and sweat-wicking functional additives after finishing the fabric, because the function of the three kinds of yarns is yarn dyeing. Adding additives after finishing the fabric will cause the function of the yarn to be destroyed
