Problems solved by technology

However, the clothes made of ordinary waterproof coated fabrics are not breathable, which is not conducive to the emission of water vapor from the human body, causing the humidity of the human body surface to increase significantly, so that it feels stuffy when worn in summer, and feels damp and cold when worn in winter

Abstract

The invention discloses a method for preparing waterproof moisture-permeable coated fabrics. The method includes thoroughly washing and drying the surfaces of fabrics, then placing the fabrics in low-temperature plasma devices and carrying out low-temperature plasma treatment on the fabrics in oxygen atmosphere to obtain pretreated textile fabrics; driving the fabrics by setting machines to transmit the fabrics through impregnation liquid, impregnating the fabrics and then rolling out redundant impregnation liquid by the aid of rollers; driving pad-rolled fabrics by the setting machines to sequentially transmit the pad-rolled fabrics through 8 drying tanks and carrying out setting steps on the fabrics. The pickup is 80-89% after the redundant impregnation liquid is rolled out by the rollers. The method for preparing the waterproof moisture-permeable coated fabrics has the advantages that moisture-permeable micro-pores can be formed in films, and the moisture-permeable micro-pores in the films are excellent in moisture transmissibility; the moisture permeability of coated textile fabrics can be improved under double moisture-permeable effects, the waterproof moisture-permeable coated fabrics are excellent in washing fastness, and accordingly the method has an excellent market promotion value.

Description

technical field [0001] The invention relates to a preparation method of a waterproof and moisture-permeable coating fabric, which belongs to the field of textile processing. technical background [0002] Fabric finishing is a process of improving the appearance and feel of fabrics, improving wearability or endowing special functions through chemical or physical methods. It is the "icing on the cake" processing process of textiles. Now the development of fabric finishing technology is developing in the direction of functionalization, differentiation and high-grade of products, diversification and depth of processing technology, and emphasizes on improving the wearing performance of products and increasing the added value of products. In recent years, various new technologies have been introduced and borrowed from other technical fields to improve the processing depth and obtain good finishing products. As human beings pay more and more attention to environmental pollution ...
