Abstract

An improved grafted starch sizing agent comprises, by weight, 6-12 parts of carboxymethylcellulose, 40-60 parts of potato starch, 8-15 parts of ethyl methacrylate, 4-7 parts of nanometer silicon nitride, 1.2-2 parts of potassium hydroxide, 8-16 parts of diphenyl ketone of ethanol butyl ether, 6-14 parts of methylbenzene, 4-6 parts of anti-skinning agents, 5-10 parts of alcohol, 1.5-2.5 parts of alkali, 15-20 parts of polyurethane resin, 3-5 parts of bridging agents, 12-24 parts of polyacrylate, 8-16 parts of tributyl phosphate and 5-7 parts of glycerin. The improved grafted starch sizing agent has the advantages that very good film-forming performance and adhesiveness are achieved, the sizing agent is stable in viscosity, a sizing film is complete, and the weaving efficiency is effectively improved.

Description

technical field [0001] The present invention relates to an improved grafted starch size. Background technique [0002] Sizing can increase the smoothness of the warp yarn, thereby reducing the breakage of the warp yarn during the weaving process, thereby reducing the number and time of loom stoppages. After more than 20 years of debate and research, the main purpose of warp sizing is wear resistance and fit hairiness. In the weaving process, the size film covered on the surface of the yarn is the main bearer of friction, and the wear resistance is the comprehensive performance of the size adhesion and the strength and elongation of the size film. It not only requires the size to have good adhesion Adhesive properties, but also have better film-forming properties. There are three types of textile size, starch, polyvinyl alcohol (PVA) and acrylic size, and these three types of size are still mainly used at home and abroad. But there are some defects in all three, and starch...
