Problems solved by technology

Knitted fabrics with water- and oil-repellent functions are very common in the market at present, but they are basically obtained by padding water- and oil-repellent finishing agents during finishing. This method destroys the hydrophilicity of fabrics and seriously affects Fabric wicking, breathability and wearing comfort
In order to improve the wearing comfort of water- and oil-repellent functional fabrics, the hydrophilicity and air permeability of the fabric must be considered. Breathable and sweat-wicking functions, among which coating finishing is the most commonly used method, that is, coating water-repellent substances on the surface of hydrophilic fabrics to achieve the functions of surface water repellency and inner layer water absorption, but the stability of the existing technology finishing products is not good , the reverse hydrophilic effect is not ideal
[0003] The application date is September 22, 2005. The Chinese invention patent specification with the patent number 200510060885.5 discloses a single-sided water-repellent and oil-repellent knitted fabric and its production method. It is composed of a hydrophilic yarn and a water-repellent yarn. Knitted fabrics made by weaving and their processing methods. This method has a long process flow and requires functional finishing of the yarns, which requires high technological requirements.

Abstract

The invention discloses a processing method of a water-repelling ventilating cellulose fiber knitted fabric; the processing method is characterized in that: the whole technological process is that: fabric blank-washing and dehydration-hydrophily finishing-dehydration and drying-water repellency finishing-washing for two times-dehydration and drying-calendering-formation-finished goods; the processing method has the advantages that the processing method is simple, the processed fabric has good water repellency on the front surface and hydrophily on the back surface, so as to lead the fabric tohave good performance such as ventilating and perspiration, and dry and comfortable wearing performances; in addition, the finishing effect is durable and the washing fastness is good; in addition, calendering is carried out to the fabric blank before the fabric blank is finalized, so as to improve the luster and handfeel of the fabric.

Description

technical field [0001] The invention relates to the finishing field of knitted fabrics in the textile industry, in particular to a processing method of water-repellent and air-permeable cellulose fiber knitted fabrics. Background technique [0002] With the improvement of living standards, consumers' requirements for the grade and functionality of clothing are constantly increasing, especially for the comfort of clothing. Knitted fabrics with water- and oil-repellent functions are very common in the market at present, but they are basically obtained by padding water- and oil-repellent finishing agents during finishing. This method destroys the hydrophilicity of fabrics and seriously affects The fabric is sweat-wicking, breathable and comfortable to wear. In order to improve the wearing comfort of water- and oil-repellent functional fabrics, the hydrophilicity and air permeability of the fabric must be considered. Breathable and sweat-wicking functions, among which coating ...
