Abstract

The invention discloses high film-formation cation grafted high-performance starch. The size is composed of corn starch, 3-chlorine-2-hydroxypropyl chloride, melamine hydrochloride and peroxysulphate through a dry method mixed with etherification grafting reaction, wherein the mass contents of the raw materials are as follows: 80-95% of corn starch, 1-10% of 3-chlorine-2-hydroxypropyl chloride, 1-6% of melamine hydrochloride, and 0.1-12% of peroxysulphate. The high film-formation cation grafted high-performance starch disclosed by the invention is environment-friendly, good in anti-aging performance, stable in size viscosity, fatigue resistant, good in size film-formation, easy to desize, and has strong adhesive power to cotton and terylene, the waste size is easy to process, easy to biodegrade, has small pollution to the environment, and the zero pollutant discharge is realized in the production process.

Description

technical field [0001] The invention belongs to the field of textile industry, and in particular relates to a high-film-forming cationic grafted high-performance starch in the yarn sizing process of the textile industry. Background technique [0002] In the yarn sizing process in the textile industry, because polyvinyl alcohol (PVA) size has excellent film-forming properties, adhesion and better compatibility with other sizes, it is considered to solve the problem of polyester-cotton blending. The most ideal size for spinning and pure cotton fine size, high density and high difficulty varieties. However, since the price of polyvinyl alcohol (PVA) sizing is much higher than that of starch sizing, coupled with polyvinyl alcohol (PVA) sizing and some refractory sizing, it is difficult to treat the sizing wastewater after desizing, causing environmental pollution. pollute. The damage to the environment and pollution problems have attracted widespread attention, especially the ...
