Abstract

The invention relates to a method for preparing a mould-proof fabric by foaming finishing, for preparation of the mould-proof fabric by subjecting textile to foaming finishing. The foaming finishing includes: pre-treating an inorganic antimicrobial agent of which the average grain size ranging from 1 to 100 nm by a dressing agent to obtain a modified inorganic antimicrobial agent, subjecting a system consisting of the modified inorganic antimicrobial agent, an organic antimicrobial agent, a foaming agent and a solvent to foaming to obtain foam, and finally drying after coating surface of the fabric with the foam, wherein the dressing agent refers to chemical compounds capable of being bonded with the inorganic antimicrobial agent under actions of hydrogen bonds, covalent bonds or physicaladsorption. The method is simple, easy to implement, low in cost, and wide in application range; the dressing agent modified inorganic antimicrobial agent and the organic antimicrobial agent are subjected to the foaming finishing, so that mould proofing performance and functional persistence of the fabric are improved.

Description

technical field [0001] The invention belongs to the technical field of functional fabrics, and relates to a method for preparing mildew-proof fabrics through foam finishing. Background technique [0002] With the increasing pressure in people's life and work, more and more people have begun to devote themselves to leisure and outdoor sports, which directly drives the development of functional fabrics. The application of functional fabrics not only increases the added value of fabric products, but also reflects people's pursuit of a comfortable and convenient lifestyle and the protection of their own health and safety. At present, functional fabrics such as comfort, regeneration, environmental protection, anti-mildew and antibacterial, and negative ions are more popular in the market. Functional fabrics in developed countries are developing rapidly. According to reports, functional textiles accounted for 39% of all textiles in Japan, 21% in Europe, and 28% in the United Sta...
