Problems solved by technology

[0005] The purpose of the present invention is to provide a method for anti-pinhole drilling of down jacket fabrics, which solves the problem of down drilling in down jacket fabrics, especially the problem of down drilling at sewing pinholes, by finishing (coating) the fabrics. The good combination of glue can meet the anti-drilling effect, especially the anti-drilling effect at the sewing pinhole. At the same time, the optional coating glue can ensure the anti-drilling performance, cold resistance and permeability of the fabric with low weight gain. Wetness, washability, softness and other comprehensive indicators make the fabric more comfortable to wear under the premise of satisfying functionality

Abstract

The method for preventing pinhole drilling of down jacket fabrics according to the present invention has the main technical characteristics that 100 parts of polyether-type polyurethane coating glue, 20-30 parts of hydroxyl-terminated polydimethylsiloxane emulsion, and 1-30 parts of isocyanate crosslinking agent are used. 1.5 parts, 1.2-1.8 parts of cross-linking accelerator, 3-5 parts of silica matting powder, 15 parts of methyl ethyl ketone or toluene are mixed to make a coating glue, which is coated on the fabric with a floating knife coater and dried Weight gain 4-6g / m2. Its anti-sewing pinhole drilling effect is good, while ensuring the fabric's cold resistance, moisture permeability, washability, and softness.

Description

technical field [0001] The invention relates to the finishing technology of textile fabrics, in particular to a processing method for anti-pinhole drilling of down jacket fabrics, so as to solve the problem of down drilling at sewing pinholes of down jacket fabrics. Background technique [0002] The phenomenon of down jacket drilling down has been perplexing down fabric production enterprises and garment processing enterprises, and has also brought a lot of inconvenience to consumers. Industry workers have also been committed to the research and development of anti-drill down fabric products and anti-drill down garment processing technology. [0003] The anti-drilling effect of down jacket fabrics is mainly achieved from several aspects. One is by increasing the weaving density of the fabric, the other is by mirror calendering, and the third is by coating the fabric with polyurethane or silicone coating glue, or by finishing Agent padding treatment. To improve the anti-dri...
