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 with reference to specific embodiments.

[0017] This embodiment is applicable to the textile size of silk fabrics, and its components are proportioned as follows by mass:

[0018] Protein slurry: 70 parts, nano-silica modified starch: 20 parts, polyacrylate emulsion: 8 parts, modified silicone oil defoamer: 2 parts, protein amino acid: 6 parts; sodium sulfamate: 3 parts; Polyacrylate: 1 part;

[0019] Nano-silica modified starch is obtained by mixing hydroxypropyl modified starch and silicon powder, adding deionized water, adding sodium hydroxide and methanol, hydrolyzing and then drying and purifying. Among them, hydroxypropyl modified starch: silicon powder: hydrogen The mass ratio of sodium oxide:methanol is: 100:6:0.1:0.2;

[0020] The protein slurry is obtained by adding soybean protein to ethanol solution with a concentration of 70%, stirring at a constant speed for 15 minutes at 46 °C, adjusting the pH valu...

Abstract

The invention relates to textile size applicable to real silk fabrics. The textile size comprises the following components in mass ratio: 70 parts of protein size, 20 parts of nano silicon dioxide modified starch, 8 parts of polyacrylate emulsion, 2 parts of modified silicone oil defoaming agent, 6 parts of argine monohydrochloride, 3 parts of sodium sulfamate and 1 part of polyacrylate. According to the textile size applicable to real silk fabrics, the protein size is taken as a primary raw material, the nano silicon dioxide modified starch and the polyacrylate emulsion 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; experiments show that the textile size is particularly applicable to the sizing of the real silk fabrics; as the formula does not contain polyvinyl alcohol, the textile size is more environment-friendly.

Description

technical field [0001] The present invention relates to a textile size suitable for silk 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, appropriately increase the strength of the yarn, and reduce the elongation to withstand the mechanical force of the warp during the weaving process. Improve the weavability of the yarn. [0003] At present, the size of warp sizing mainly includes starch, polyvinyl alcohol (PVA) and polyacrylic acid. Starch is a natural polysaccharide polymer with good film-forming properties of the size, strong affinity with natural fibers, and easy desizing; however, starch size is not strong enough for sizing, not wear-resistant, and has insufficient affinity with polyester fibers. Polyvinyl alcohol slurry film has high strength, good flexibility and good fluidity, but polyvinyl alcohol is difficult to desizing and has great en...
