preparation example Construction

[0030] The invention provides a method for preparing a temperature-sensitive waterproof and moisture-permeable fabric, comprising the following steps:

[0031] (1) Soak the base cloth in hydrochloric acid to carry out hydrolysis treatment, the base cloth is a fabric that can be hydrolyzed to obtain amino and / or hydroxyl structures;

[0032] (2) Soak the hydrolyzed base cloth obtained in the step (1) in a glutaraldehyde solution to carry out a pre-crosslinking reaction, and then perform a padding treatment on the obtained pre-crosslinked base cloth in a temperature-sensitive hydrogel to obtain a cross-linked fabric;

[0033] (3) Coating the coating agent on the surface of the cross-linked base cloth obtained in the step (2) and then baking to obtain a temperature-sensitive waterproof and moisture-permeable fabric.

[0034] In the present invention, the base cloth is soaked in hydrochloric acid for hydrolysis treatment, and the base cloth is a fabric containing amino and / or hyd...

Abstract

The invention provides temperature-sensitive waterproof moisture-permeable shell fabric and a preparation method thereof. The preparation method includes soaking base cloth in hydrochloric acid for hydrolysis, wherein the base cloth is shell fabric which can contain an amino and / or hydroxy structure after being hydrolyzed; soaking the hydrolyzed base cloth in a glutaric dialdehyde solution for pre-crosslinking reaction, and subjecting the pre-crosslinked base cloth to padding treatment in temperature-sensitive hydrogel so as to obtain crosslinked base cloth; applying the surface of the crosslinked base cloth with a coating agent and baking so as to obtain the temperature-sensitive waterproof moisture-permeable shell fabric. The temperature-sensitive waterproof moisture-permeable shell fabric has the advantages of good temperature-sensitive performance and waterproof moisture-permeable performance as well as excellent washability because of good bonding performance and high bonding firmness between the temperature-sensitive hydrogel and nylon fabric.

Description

technical field [0001] The invention belongs to the technical field of textile fabric production, and in particular relates to a temperature-sensitive waterproof and moisture-permeable fabric and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people's requirements for the function of textile fabrics are getting higher and higher. Discharging the water vapor produced by the human body out of the clothing in a non-perspiring manner is an important performance required for clothing fabrics, and the amount of heat and sweat released by the human body is different under different temperature and exercise conditions. Therefore, in order to maintain the comfort of the wearer, the requirements for the moisture permeability of textile clothing are different in different environments. Low moisture vapor transmission ensures warmth. [0003] In the prior art, a temperature-controlled moisture-permeable fabric finishing a...
