Water-repellent anti-contamination hygroscopic perspiratory composite tissue knitted fabric and production method thereof

Abstract

The invention relates to a water-repellent anti-contamination hygroscopic perspiratory composite tissue knitted fabric produced in knitting industry and a production method thereof. An outer coil of the knitted fabric is made of yarn treated by water-repellent anti-contamination technology; a coil at a middle connection layer is made of natural fiber yarn with good hygroscopic and water absorbent performance; an inner coil is made of hygroscopic fiber yarn, and the hygroscopic fiber yarn is treated by hydrophilicity, has a microcellular structure and is in a deformed cross section; the fabric tissue is double-rib double-layer composite tissue, and is knitted on a 2+2 needle track double-surface circular knitting machine; and the knitted fabric is subjected to preforming, degreasing and cleaning, softening, dewatering, expanding, drying, forming and the like. The outer layer of the provided knitted fabric has excellent water-repellent anti-contamination function, and the inner layer has excellent hygroscopic perspiratory function; the knitted fabric has soft hand feel, good permeability and elasticity and antistatic performance, and is widely applied to sportswear, summer clothing, work clothes of hotels and oil field, regimentals and the like; three-tissue structure of the knitted fabric is formed by one-step knitting so that the production technology has easiness in control and the product quality is reliable.

Description

technical field [0001] The invention relates to a knitted fabric produced in the textile industry and a production method thereof. It is a functional composite knitted fabric with an outer layer that is water-repellent and stain-resistant and an inner layer that absorbs moisture and sweat and a production method thereof. It can be used for various types of clothing, especially Used as a fabric for sportswear and workwear. Background technique [0002] The water repellency of a fabric refers to the ability of the fabric to flush water droplets off its surface. Water-repellent finishing is to change the performance of the fiber surface, change the hydrophilicity of the fiber surface to hydrophobicity, form a hydrophobic structure on the surface of the fabric like a lotus leaf surface, enhance the surface tension of the fabric, and use the additional pressure of the fabric capillary to make water droplets Tighten as much as possible without loosening, and prevent liquid wa...

Problems solved by technology

[0007] The existing water-repellent, anti-fouling, moisture-absorbing and sweat-wicking fabrics, one is to achieve the effect of different functions on the inside and outside of the fabric through fiber compounding or filming, but this method has problems such as cumbersome processing, high cost, and limited wearing performance; The second is to achieve different functions on the inside and outside through the dyeing and finishing method. This method is still in the process of development and research at home and abroad. The outer surface of the fabric is modified with a fluorine-containing water repellent agent to make it have a water-repellent and anti-fouling function. The inner surface has hygroscopicity after hydrophilic treatment. The process is to apply the water-repellent additive to the outer surface of the fabric by coating or printing technology, and then use the padding method to complete the moisture absorption and perspiration processing on the other side, the inner surface. However, this method is difficult to control the thickness and uniformity of coverage, and there are problems such as unsatisfactory water repellency and moisture absorption performance, low water pressure that water repellency can withstand, easy mutual interference between waterproof and moisture absorption, poor washing resistance, and poor hand feeling.
