Abstract

The invention relates to a waterborne polyurethane coating adhesive for a textile and a fabric treatment method. The waterborne polyurethane coating adhesive is prepared by compounding 60-70 parts byweight of waterborne polyurethane emulsion, 2.0-4.0 parts by weight of organic silicon modified elastic microspheres, 2.0-4.0 parts by weight of an anti-static agent, 0.5-1.0 part by weight of an ultraviolet absorbent, 0.2-0.3 part by weight of a waterborne de-foaming agent, 2.0-4.0 parts by weight of an association type waterborne polyurethane thickener and 30-40 parts by weight of deionized water. The fabric achieves the functions of air permeability, water pressure resistance, ultraviolet resistance, static electricity resistance and downproofness after being coated with the waterproof, glossy and waterborne polyurethane adhesive.

Description

technical field [0001] The invention relates to a water-based polyurethane coating adhesive for textiles and a post-treatment method for textile fabrics, in particular to a water-based polyurethane coating adhesive for textiles with the characteristics of air permeability, water pressure resistance, ultraviolet resistance, antistatic, and anti-drilling functions. And post-processing method of textile fabrics, especially suitable for nylon fabrics. Background technique [0002] At present, there are various styles of down jackets on the market. With the improvement of living standards, the functionality of down jackets is not limited to keeping warm. People also have more fashionable pursuits for the feel and style of down jackets. There is also a broader demand for functionality. [0003] For the functionality of down jacket fabrics, anti-drill down is the first demand for down jacket fabrics, and what is currently needed in the market is not only down jacket fabrics with a...
