Abstract

The invention provides a finishing method of a waterproof and moisture-permeable clothing fabric. The finishing method includes the steps that silk fibroin powder, an initiator and acrylic acid are added into water in sequence to react to obtain a grafted modified silk fibroin dispersion solution, then chitosan, calcium chloride and deionized water are added and made into a thick solution, then atextile is pretreated with water glass liquid and then subjected to pad steam for two times accordingly through the thick solution to obtain a pre-finished fabric, then a foaming agent, a three-proofing finishing agent and acrylic ester emulsion are made into a finishing solution, the finishing solution is sprayed on the surface of the pre-dried fabric by ultrasonic atomization to form a coating,and thus the waterproof and moisture-permeable clothing textile fabric is obtained. According to the method, the acrylic grafted silk fibroin powder with excellent water absorption performance is fixed on fabric fibers, the requirements of moisture permeability and comfort for clothing fabrics are met, the finishing solution is sprayed on the fabric surface to form the firm coating with good micropores, moisture permeability is facilitated, and the waterproofness is good.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for finishing waterproof and moisture-permeable clothing fabrics. Background technique [0002] With the rapid development of functional textiles, the traditional means of simply relying on functional fibers to enhance the function of textiles is becoming more and more limited. Although functional fibers of various materials have been continuously developed, it is still difficult to meet the functional requirements of functional textiles. By applying high-tech finishing technology to textile fabrics to increase their functionality to protect textiles from various adverse environments, the obtained finishing coating is the best way to quickly obtain various functional textiles. Functional textiles can be designed for various purposes through finishing treatments such as UV radiation, harsh climates, microorganisms or bacteria, high temperatures, chemicals such as acids,...
