Problems solved by technology

[0004] However, the surface tension of PTFE is low, and it is difficult to combine with other materials, which makes it easy to delaminate between PTFE film and polyurethane during use.
The polytetrafluoroethylene film and polyurethane prepared by the above method are difficult to fuse, the peel strength between them is low, and it is easy to delaminate

Abstract

The invention relates to a preparation method of windproof breathable textile. The preparation method mainly includes the steps: firstly, mixing vinyl polysiloxane, nano silica, silazane and ethyl alcohol in a high-shear mixing machine, cooling to room temperature to obtain a uniform mixture after treatment in vacuum at the temperature of 200 DEG C, and adding thermal expansion microcapsules and catalyst chloroplatinic acid prior to filtering to obtain a component A; secondly, adding lignocellulose into a reaction kettle, then adding barium sulfate powder and diatomaceous earth with uniform stirring and mixing, performing ultrasonic dispersion prior to ball milling dispersion, then adding other rest raw materials besides the component A, uniformly stirring to obtain a component B, and mixing the components A and B to prepare windproof coating via ultrasonic dispersion and ball milling dispersion; thirdly, coating the polyester textile with the coating by means of a tape casting method. When the coating is used for coating the surface of the textile, the textile and a polyurethane composite film are non-delaminated, the polyurethane film layer has excellent windproof and moisture-permeable effects, and the textile is good in hand feel.

Description

Technical field [0001] The invention belongs to the field of laminated fabric manufacturing, and specifically relates to a method for preparing wind-proof and breathable textiles. Background technique [0002] The two-way stretched PTFE microporous film windproof and moisture-permeable laminated fabric is a high-tech product that integrates moisture, wind and chemical functions. The laminated fabric is widely used in outdoor sportswear, casual wear, Windproof and breathable shoes and other fields. The microstructure of the film is composed of "fibrils-nodes", the film thickness is 5 to 80 microns, the pore diameter is 0.1 to 5 microns, there are about 9 billion micropores per square inch, and the opening rate is as high as 80%. Due to the large specific surface area of ​​the PTFE film, it is easy to absorb dust, salt in human sweat, grease, cosmetics and other substances, and detergents are also easy to remain in the pores, resulting in reduced wind resistance. Therefore, coati...
