Embodiment 1

[0018] Put 83kg of corn starch, 7kg of cetyltrimethylammonium chloride, 5kg of povidone, and 5kg of calcium persulfate into the reaction tank respectively, and carry out dry mixed etherification grafting reaction at 68°C for 45min Finally, the reaction is terminated, and the material is unloaded, packaged, and put into storage. When the customer is using it, add 800kg of clear water to gelatinize and heat up to 95°C or add clear water in a high-pressure tank to heat up to 125°C and keep it warm for 30-45min to carry out etherification and oxidation compound reactions to prepare the emulsion for fabric sizing.

[0019] After the slurry adhesion test, the pure cotton adhesion is 105N, and the polyester-cotton adhesion is 148N. Carry out the same adhesion test to the slurry prepared in Example 1 in CN102733190A, CN102733191A, and CN102605618A respectively, wherein CN102733190A pure cotton adhesion is 91N, polyester cotton adhesion is 115N; CN102733191A pure cotton adhesion is 93N...

Embodiment 2

[0022] Put 85kg of corn starch, 6kg of cetyltrimethylammonium chloride, 4kg of povidone, and 5kg of potassium hydrogen persulfate into the reaction tank respectively, and carry out the dry mixed etherification grafting reaction at a temperature of 68°C After 45 minutes, the reaction was terminated, and the material was unloaded, packaged, and put into storage. When the customer is using it, add 700kg of water to gelatinize and heat up to 95°C or add water in a high-pressure tank to heat up to 125°C and keep it warm for 30-45min to carry out etherification and oxidation compound reactions to obtain a fabric sizing emulsion. After the slurry adhesion test, the pure cotton adhesion is 102N, and the polyester-cotton adhesion is 145N. Its biodegradation test grade 9. The emulsion has good anti-aging performance. The slurry does not freeze after being placed at room temperature for 48 hours, and the fluidity of the slurry is good, and there is no change compared with that before 48...

Embodiment 3

[0024] Put 90kg of cornstarch, 4kg of cetyltrimethylammonium chloride, 3kg of povidone, and 3kg of ammonium persulfate into a reaction tank respectively, and carry out a compound mixing reaction at a temperature of 68°C for 45 minutes to terminate the reaction. Material packaging, storage. When the customer is using it, add 680kg of water to gelatinize and heat up to 95°C or add water in a high-pressure tank to heat up to 125°C and keep it warm for 30-45min to carry out etherification and oxidation compound reactions to obtain fabric sizing emulsion.

Abstract

The invention discloses aging-resistant cation-grafted high-performance starch. The starch is prepared through the dry mixing and etherification grafting reaction of the following raw materials in percentage by mass: 80-95% of corn starch, 1-10% of cetyl trimethyl ammonium chloride, 1-6% of povidone and 0.1-12% of persulfate. The aging-resistant cation-grafted high-performance starch is environment-friendly and has good aging resistance, the starch liquid is stable in viscosity, has strong adhesive power to both cotton and dacron, is fatigue-resistant, has good film forming property and is easy to destarch, the starch liquid wastewater is easily treated and easily biodegraded and hardly causes pollution to the environment, and thus, 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 an anti-aging 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 fabric...
