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 invention discloses a down coat fabric treatment method for preventing down feather from escaping from needle holes. The down coat fabric treatment method is mainly technically characterized in that 100 parts by weight of a polyether polyurethane coating adhesive, 20-30 parts of a hydroxy terminated polydimethylsiloxane emulsion, 1-1.5 parts of an isocyanate cross-linking agent, 1.2-1.8 parts by weight of a cross-linking promoter, 3-5 parts of silicon dioxide extinction powder and 15 parts of butanone or toluene are mixed to prepare a coating adhesive, which is applied to a fabric by a floating knife coating machine, and the dry weight increase reaches 4-6 g / m<2>. The effect of preventing down feather from escaping from sewing needle holes is good, and the cold resistance, moisture permeability, washing fastness and flexibility of a fabric are ensured.

Description

Technical field [0001] The present invention involves the finishing technology after the textile fabric, which is specifically involved. Background technique [0002] The phenomenon of down jackets drilling has always plagued the down fabric manufacturers and clothing processing enterprises, and it also brings many inconvenience to consumers.Industry workers have also been committed to the research and development of anti -drilling fabric products and anti -diamond velvet clothing processing technology. [0003] The anti -diamond -proof effect of down jackets is mainly achieved from several aspects. One is to increase the weaving density of the fabric, the other is to organize it through the mirror surface, and the third is to coat with polyurethane or organic silicon coating adhesive, or use organizational collation.Polish treatment.To improve the anti -diamond velvet effect of the fabric.For example, the patented CN 102433743 B's "processing method of anti -diamond velvet fabri...
