Problems solved by technology

[0004] The invention provides a new type of anti-down technology for textiles, which is used to solve the disadvantages of our traditional down jacket running down, especially the problem of down drilling at sewing pinholes, through the good combination of fabric base cloth and coating glue. Satisfies the anti-drilling effect, especially the anti-drilling effect at the sewing pinhole, and the optional coating glue can ensure the anti-drilling performance, cold resistance, moisture permeability and washability of the fabric with a lower weight gain Comprehensive indicators such as softness and softness make the fabric more comfortable to wear under the premise of satisfying functionality

Abstract

Disclosed is a novel textile downproof technology .The novel textile downproof technology comprises the following steps of 1, selecting a fabric, wherein the fabric is a plain weave fabric woven by nylon full-stretching silk, the yarn count is 20 D-40 D, and the density is 290 Tex-400 Tex; 2, performing water-repellency arrangement on the fabric, wherein the grade of getting wet is not smaller then 3; 3, performing calendering on the fabric obtained after water-repellency arrangement through a calender, wherein the pressure is 9-11 MPa, the temperature is 100-110 DEG C, and the speed is 30-40 m / min; 4, preparing a coating adhesive .The downproof effect is achieved through the good combination of a base fabric and the coating adhesive, particularly, the downproof effect at a sewing needle hole is achieved, meanwhile, the selected and prepared coating adhesive can ensure comprehensive indicators of downproofness, cold resistance, moisture penetrability, washing fastness, flexibility and the like of the fabric with the low weight increment, and the wearing comfort of the fabric is better on the premise of achieving functionality .

Description

technical field [0001] The invention relates to a novel cashmere-proof technology 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 my 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 developm...
