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

[0017] The present invention will be further described below in conjunction with specific embodiments.

[0018] The low-pollution textile size of this embodiment, its component is as follows by mass ratio:

[0019] Nano-silica modified starch: 64 parts, protein slurry: 18 parts, polyvinyl alcohol: 5 parts; polyacrylate emulsion: 11 parts, modified silicone oil defoamer: 2 parts; protein amino acid: 3 parts; kaolin : 4 parts; Sodium sulfamate: 3 parts; Polyacrylate: 1 part;

[0020] 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: 100:5:0.1:0.2;

[0021] The protein slurry is obtained by adding soybean protein to a sodium hydroxide solution with a concentration of 0.2%, stirring at a constant speed for 15 minutes at...

Abstract

The invention relates to a low-pollution textile sizing agent. The low-pollution textile sizing agent comprises following components in parts by mass: 64 parts of nano silicon dioxide modified starch, 18 parts of a protein sizing agent, 5 parts of polyvinyl alcohol, 11 parts of polyacrylate emulsion, 2 parts of a modified silicone oil de-foaming agent, 3 parts of protein amino acid, 4 parts of kaolin, 3 parts of sodium sulfamate and 1 part of polyacrylate. The sizing agent with the formula has good film-forming property and permeability; the formula contains less polyvinyl alcohol so that the pollution to the environment is low.

Description

technical field [0001] The invention relates to a low-pollution textile slurry. 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 polyvinyl alcohol is diffic...
