A preparation method of textile size suitable for high-count cotton fabrics

Abstract

The invention relates to a preparation method of a textile size applicable to high-count cotton fabrics. The preparation method comprises the steps of: mixing hydroxypropyl modified starch with silicon powder, adding into deionized water, adding sodium hydroxide and methyl alcohol, and carrying out drying and purification after hydrolysis to obtain nano silicon dioxide modified starch; adding soybean protein in sodium hydroxide solution, stirring at a constant speed at 40 DEG C for 15 minutes, and filtering out the precipitates to obtain protein size; pouring the nano silicon dioxide modified starch, the protein size, polyacrylate emulsion and modified silicon oil defoaming agent in a stirrer for stirring and mixing to obtain the textile size applicable to high-count cotton fabrics. The size prepared by the method has favorable film forming property and permeability, is particularly applicable to the sizing of high-count cotton fabrics as the sizing property is excellent, and is more environment-friendly as the formula does not contain polyvinyl alcohol.

Description

technical field [0001] The invention relates to a method for preparing textile slurry suitable for high-count cotton fabrics. Background technique [0002] Warp sizing is a key link in weaving engineering. The purpose of sizing is to improve the wear resistance of the yarn, reduce hairiness, increase the strength of the yarn appropriately, and reduce the elongation, so as to withstand the mechanical force of the warp yarn during the weaving process. Improve yarn weavability. [0003] At present, the sizing materials for warp yarn sizing mainly include three major sizing materials: starch, polyvinyl alcohol (PVA) and polyacrylic acid. Starch is a natural polysaccharide polymer. The size has good film-forming properties, strong affinity with natural fibers, and easy desizing; however, starch size is not strong enough in sizing, not wear-resistant, and has insufficient affinity with polyester fibers. Polyvinyl alcohol size film has high strength, good flexibility, and good sl...

AI Technical Summary

Problems solved by technology

Starch is a natural polysaccharide polymer with good film-forming properties, strong affinity with natural fibers, and easy desizing; however, starch sizing is not strong enough, not wear-resistant, and has insufficient affinity with polyester fibers

Polyvinyl alcohol size film has high strength, good flexibility, and good slurry fluidity, but polyvinyl alcohol is difficult to desizing and causes great environmental pollution

Polyacrylic acid size is a general term for homopolymers, copolymers and blends of acrylic monomers. It has low viscosity, good fluidity, good adhesion to synthetic fibers, and can be easily mixed with starch and PVA size. Good mixing, suitable for warp sizing of various fibers, but the high price of polyacrylic acid sizing will push up the production cost of printing and dyeing enterprises
