Abstract

The invention discloses a method for processing anti-aging, cold-resistant, antibacterial and high-moisture-penetrability raincoat fabric. The method includes the steps that A, 100 parts of a waterborne waterproof and high-moisture-penetrability polyurethane adhesive, 5-10 parts of a negative-ion or nonionic fluorine-containing waterproof agent, 5-8 parts of terminal-hydroxyl polydimethylsiloxane emulsified products, 3-5 parts of poly-methylurea resin and a proper amount of water are prepared into a bottom-layer coating adhesive; B, 100 parts of a waterborne polyurethane adhesive, 5-8 parts of micro-pore lignocellulose of 15 microns to 30 microns, 6-8 parts of an antibacterial deodorizing finishing agent, 1-3 parts of an isocyanate cross-linking agent and a proper amount of water are prepared into a face-layer coating adhesive; dacron, chinlon, polyester and nylon blended yarn weaved fabric is subjected to coating treatment, and the raincoat fabric is prepared. The technology is simple, operating is convenient, and the product environmental protection performance is good.

Description

technical field [0001] The invention relates to the field of textile coatings, in particular to a processing method for anti-aging, cold-resistant, antibacterial, high-moisture-permeable polyester, nylon and polyester-nylon blended raincoat fabrics. Background technique [0002] At present, the existing raincoat fabrics with more functions and better performance on the market are basically obtained by processing solvent-based waterproof and moisture-permeable polyurethane. Because it contains a large amount of organic solvents such as toluene and dimethylformamide, it is not environmentally friendly and poses a serious threat to human health. [0003] In addition, most moisture-permeable raincoat products prepared with waterproof and moisture-permeable polyurethane coating agents will have problems of moisture absorption and swelling when the product encounters water, which will increase the weight of the fabric and make it uncomfortable to wear. At the same time, summer ra...
