Waterproof textiles or waterproof textiles that have the functions of moisture permeability, air permeability and heat preservation at the same time have been applied more and more in outdoor emergency clothing, fire protection clothing, canopies and medical protective clothing and other products.At present, there are many processing technologies for waterproof and moisture-permeable textile materials. The products produced by different finishing technologies have different waterproof and moisture-permeable effects. There are many testing methods to determine the waterproof performance of textiles at home and abroad, but they are mainly divided into two aspects.
