Abstract

The invention discloses high-film-forming-property high-performance cationic graft starch. The starch is produced in a manner that raw materials including corn starch, 3-chloro-2-hydroxypropyl trimethyl ammonium chloride, povidone and persulfate are subjected to dry mixing and etherification graft reaction, wherein the mass content of each raw material is as follows: the mass content of the corn starch is 80-95%, the mass content of the 3-chloro-2-hydroxypropyl trimethyl ammonium chloride is 1-10%, the mass content of the povidone is 1-6%, and the mass content of the persulfate is 0.1-12%. The high-film-forming-property high-performance cationic graft starch disclosed by the invention is environment-friendly and has good ageing resistance, the starch liquid is stable in viscosity, higher in adhesion and fatigue resistance for both cotton and terylene, good in film forming property and easy to destarch, starch liquid wastewater is easy in treatment and biodegradation and little in environmental pollution, and the zero-pollution emission is achieved during production.

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 ...
