Abstract

A down leakage preventing process for textiles is characterized by including the following steps: (1) selecting plain weave fabrics made of full-stretched yarns of chinlon, wherein the yarn count ranges from 20D to 40D, and the density ranges from 290Tex to 400Tex; (2) subjecting the fabrics to water repellent finishing, wherein the wetting grade is higher than or equal to grade 3; (3) by a calender, calendering the fabrics subjected to water repellent finishing under the pressure of 9-11 MPa and at the temperature of 100-110 DEG C, wherein the speed ranges from 30 m / min to 40 m / min; (4) preparing a coating adhesive. The down leakage preventing process has the advantages that the down leakage preventing effect, especially the down leakage preventing effect at sewing holes, is achieved through good combination of fabric base cloth with the coating adhesive; the selected coating adhesive can ensure the comprehensive indexes, such as down leakage resistance, cold resistance, moisture permeability, washability and softness, of the fabrics on the premise of low weight gain, so that the fabrics are highly comfortable while meeting the need for functionality.

Description

technical field [0001] The invention relates to a downproofing process for textiles, which belongs to the field of clothing textiles. Background technique [0002] With the development of science and technology, the requirements for clothing are getting higher and higher, so we must seize the favorable market. For our country, this high-tech, high-grade textile new down-proof technology is even more needed. In recent years, our company has trial-produced this new type of anti-down technology for textiles, which has created favorable conditions for the development of textiles and clothing in our country. It will bring a new market to improve the versatility and diversification of textiles. [0003] In the past, the development of the textile industry was restricted by various factors, so the future textile industry must adhere to the multi-functionality and diversification of varieties. Only in this way can a new room for growth be created for the future development of fab...
