Embodiment Construction

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

[0017] Present embodiment is applicable to the weaving size of linen fabric, and its component is as follows by mass ratio:

[0018] Protein slurry: 75 parts, nano-silica modified starch: 15 parts, glycerin: 8 parts, modified silicone oil defoamer: 2 parts, protein amino acid: 4 parts; sodium sulfamate: 2 parts; polyacrylate : 2 copies;

[0019] Nano-silica modified starch is obtained by mixing phosphate-modified starch and silicon powder, adding to deionized water, adding sodium hydroxide and methanol, drying and purifying after hydrolysis, wherein, phosphate-modified starch: silicon powder: sodium hydroxide : The mass ratio of methanol is: 100:6:0.1:0.2;

[0020] The protein slurry is obtained by adding soybean protein into a 70% ethanol solution, stirring at a constant speed for 15 minutes at 46°C, adjusting the pH value to 7-8 with 30% hydrochloric acid, and filtering...

Abstract

The invention relates to a textile size applicable to linen fabrics. The textile size comprises the following components in mass ratio: 75 parts of parts of protein size, 15 parts of nano silicon dioxide modified starch, 8 parts of glycerol, 2 parts of modified silicone oil defoaming agent, 6 parts of argine monohydrochloride, 3 part of sodium sulfamate and 1 part of polyacrylate. According to the textile size applicable to linen fabrics, the protein size is taken as a primary raw material, the nano silicon dioxide modified starch and glycerol are taken as secondary raw materials, the modified silicone oil is taken as a defoaming agent, and the four components are proportioned, so that the size has favorable film forming property and permeability, is particularly applicable to the sizing of the linen 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 flax 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 polyvinyl alcohol...
