Abstract
Description
technical field
[0001] The invention relates to an environment-friendly 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 i...

Embodiment Construction
[0017] The present invention will be further described below in conjunction with specific embodiments.
[0018] The present embodiment environment-friendly textile size, its component is as follows by mass ratio:
[0019] Nano-silica modified starch: 72 parts, protein slurry: 15 parts, polyacrylate emulsion: 11 parts, silicone 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 45°C, and then filtering off the ...
