Problems solved by technology

[0004] The invention provides a textile down-proof technology, using the new textile down-proof technology to solve the disadvantages of our traditional down jacket running down, especially the down drilling problem at the sewing pinhole, and satisfy the problem through the good combination of fabric base cloth and coating glue. Anti-drilling effect, especially satisfying the anti-drilling effect at the sewing pinhole. At the same time, the optional coating glue can ensure the anti-drilling performance, cold resistance, moisture permeability, washability, Comprehensive indicators such as softness make the fabric more comfortable to wear under the premise of satisfying functionality

Abstract

A textile down-proof process is characterized by including the steps: (1) fabric selection: selecting a plain weave fabric woven with fully-drawn nylon yarns; (2) performing water repellent finishingon the fabric; (3) calendering the fabric after water repellent finishing by a calender at the pressure of 9-11MPa at the temperature of 100-110 DEG C and at the speed of 30-40m / min; (4) preparing a coating adhesive. The yarn count of the plain weave fabric is 20D-40D, the density of the plain weave fabric is 290Tex-400Tex, and water repellent grade is larger than or equal to 3. Fabric base clothis effectively combined with the coating adhesive to achieve a down-proof effect, the down-proof effect at a sewing needle hole is particularly achieved, by the aid of the selected coating adhesive, comprehensive indexes such as down-proof performance, cold resistance, moisture penetrability, washing fastness and softness of the fabric can be ensured by low weight increase, and the wearing comfortableness of the fabric is better on the premise of meeting 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...
