A kind of preparation method of environment-friendly textile size

Abstract

The invention relates to a preparation method for environment-friendly type textile sizing agent. The preparation method comprises the following steps: mixing hydroxypropyl modified starch and silicon powder and adding a mixture into de-ionized water; adding sodium hydroxide and methanol; carrying out hydrolysis, and drying and purifying to obtain nano silicon dioxide modified starch; adding soybean protein into a sodium hydroxide solution and agitating at 45 DEG C at uniform speed for 15 minutes; filtering and removing sediment to obtain a protein sizing agent; pouring the nano silicon dioxide modified starch, the protein sizing agent, polyacrylate emulsion and an organic silicon de-foaming agent into an agitator to be agitated and mixed to obtain the environment-friendly type textile sizing agent. The sizing agent prepared by the invention has good film forming property and permeability; the sizing performance is good and a formula does not contain polyvinyl alcohol, thus the environment-friendly type textile sizing agent is very environment-friendly.

Description

technical field [0001] The invention relates to an environment-friendly textile slurry preparation method. 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 ...

AI Technical Summary

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
