Abstract

The invention discloses anti-fatigue cationic grafting starch with high performance. The anti-fatigue cationic grafting starch is prepared from the following raw materials by mass percent: 80% to 95% corn starch, 1% to 10% of acryloyl ethyl oxide trimethyl ammonium chloride, 1% to 6% of povidone and 0.1% to 12% of persulphate, wherein an etherification grafting reaction is carried out on the all the components by combination of a dry method. The anti-fatigue cationic grafting starch is environment-friendly, good in anti-fatigue performance and stable in starch fluid viscosity, and has the strong adhesive force to cotton and polyester. In addition, the starch fluid is good in film-forming performance and easy to destarch; and the wastewater caused by the starch fluid is easy to treat and easy in biodegradation, thereby causing little pollution to the environment, i.e., the zero-pollution 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-performance starch grafted with anti-fatigue cations 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 f...
