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

Embodiment Construction

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

[0017] Present embodiment is applicable to the textile slurry preparation method of linen fabric, comprises the steps:

[0018] The first step is to mix the phosphate-modified starch with silicon powder, add it to deionized water, add sodium hydroxide and methanol, perform hydrolysis, dry and purify to obtain nano-silica modified starch, wherein, phosphate-modified starch: silicon powder : sodium hydroxide: the mass ratio of methanol is: 100:6:0.1:0.2;

[0019] In the second step, soybean protein is added to ethanol solution with a concentration of 70%, and after stirring at a constant speed for 15 minutes at 46°C, the pH value is adjusted to 7-8 with hydrochloric acid with a concentration of 30%, and the protein slurry is obtained after filtering off the precipitate;

[0020] The third step, according to the weight ratio, mix 75 parts of protein slurry, 15 parts of nano-s...

Abstract

The invention relates to a preparation method of textile size of a linen fabric. The preparation method comprises the steps of mixing phosphate modified starch and silicon powder, adding the mixture into deionized water, adding sodium hydroxide and methyl alcohol for hydrolysis, and drying and purifying to obtain nano silicon dioxide modified starch; adding soybean protein into a sodium hydroxide solution, stirring at constant speed at 46 DEG C for 15min, regulating the pH value to be at 7-8 with hydrochloric acid with concentration of 30%, and filtering precipitates to obtain protein size; and pouring the protein size, the nano silicon dioxide modified starch, glycerin and a modified silicon oil defoamer into a stirrer and stirring uniformly to obtain the textile size. The textile size prepared by the method is good in film-forming property and permeability and excellent in sizing property, is particularly suitable for sizing of the linen fabric and is environmentally friendly due to no polyvinyl alcohol in the formula.

Description

technical field [0001] The invention relates to a method for preparing 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, ...
