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. It is suitable for warp sizing of various fibers, but the price of polyacrylic acid is high, which pushes up the production cost of printing and dyeing enterprises

Embodiment Construction

[0016] The present invention will be further described below in conjunction with specific embodiments.

[0017] This embodiment is applicable to the textile size of high-count cotton fabric, and its component is as follows by mass ratio:

[0018] Nano silica modified starch: 80 parts, protein slurry: 10 parts, polyacrylate emulsion: 8 parts, modified silicone oil defoamer: 2 parts, protein amino acid: 5 parts; sodium sulfamate: 2 parts; Polyacrylate: 2 parts;

[0019] Nano-silica modified starch is obtained by mixing hydroxypropyl modified starch and silicon powder, adding to deionized water, adding sodium hydroxide and methanol, drying and purifying after hydrolysis, wherein, hydroxypropyl modified starch: silicon powder: hydrogen The mass ratio of sodium oxide: methanol is: 110:6:0.2:0.4;

[0020] The protein slurry is obtained by adding soybean protein into a sodium hydroxide solution with a concentration of 0.3%, stirring at a constant speed for 15 minutes at 40°C, and t...

Abstract

The invention relates to a textile size applicable to high-count cotton fabrics. The textile size comprises the following components in mass ratio: 80 parts of nano silicon dioxide modified starch, 10 parts of protein size, 8 parts of polyacrylate emulsion, 2 parts of modified silicone oil defoaming agent, 5 parts of argine monohydrochloride, 2 parts of sodium sulfamate and 2 part of polyacrylate. The size has favorable film forming property and permeability, is particularly applicable to the sizing of the high-count cotton fabrics and is more environment-friendly as the formula does not contain polyvinyl alcohol.

Description

technical field [0001] The invention relates to a textile size 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 slurry fluidity, but poly...
