[0025] The preparation method of mixture is:

[0026] A. Mix cinnamyl-containing polyimide, modified particles and mixed solvent uniformly at a mass ratio of 9:2 to 4:13 to obtain a base liquid;

[0027] B. The mass ratio of base liquid and tetrabutyl titanate is 12:3-5, ultrasonically disperse evenly, vacuumize and defoam to obtain the mixture.

[0028] The modified particles are obtained by heating titanium dioxide, graphene, sodium dodecylbenzenesulfonate and water at a mass ratio of 7:3:0.1:20 at 90°C for 2 hours, filtering, and drying to obtain modified particles.

[0029] The mixed solvent is formed by mixing ethylene glycol and acetone at a volume ratio of 9:2-4.

[0030] In the step (4), the fabric layer is any one of cotton fabric and silk fabric

Embodiment 1

[0037] The additive is any one of sodium bicarbonate and ammonium bicarbonate.

[0038] The glue is made by mixing hydroxypropyl methylcellulose, carboxymethyl starch and water in a mass ratio of 4:3:20.

[0039] The waterproof and breathable membrane is any one of TPU film and PTFE film.

[0040] The preparation method of mixture is:

[0041] A. Mix cinnamyl-containing polyimide, modified particles and mixed solvent uniformly at a mass ratio of 9:4:13 to obtain a base liquid;

[0042] B. Disperse the base liquid and tetrabutyl titanate in a mass ratio of 12:5, and disperse them uniformly by ultrasonic, and then vacuumize and defoam to obtain the mixture. The modified particles are obtained by heating titanium dioxide, graphene, sodium dodecylbenzenesulfonate and water at a mass ratio of 7:3:0.1:20 at 90°C for 2 hours, filtering, and drying to obtain modified particles.

[0043] The mixed solvent is a mixture of ethylene glycol and acetone at a volume ratio of 9:4.

Abstract

The invention belongs to the technical field of textile fabrics, and particularly relates to a preparation method of a waterproof and breathable fabric. A PES hot melt adhesive film is used as a basefilm, and has a good flexibility, glue and additives are added to the upper part of the base film, the additives can improve pores in the glue and improve the breathability, the waterproof and breathable properties can be well enhanced through the performances of a waterproof ad breathable film and the performances of a mixture, the self-cleaning effect in the fabric can be improved through the effect of the mixture, and then the comfort degree of the fabric can be well improved through a fabric layer.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and in particular relates to a preparation method of waterproof and breathable fabrics. Background technique [0002] As consumers' requirements for clothing gradually tend to be diversified and multi-functional, heat-storing and heat-preserving fabrics are one of the key products to be developed. Because the heat transfer of clothing can basically be divided into two types: sensible heat transfer, that is, the heat transfer that can be generated by the difference between the human body temperature and the external environment, which is mainly completed through heat conduction, convection and radiation; latent heat transfer, that is, due to the difference between the human body and the external environment The moisture heat transfer caused by the difference in vapor concentration between the two is mainly completed by evaporation and perspiration. With the fashion of clothing, it is not ...
