Abstract

The invention relates to a preparation method of starch-grafted composite glutin sizing, and belongs to the technical field of textile materials. By adding hydrogenated sheep oil and hydrogenated castor oil, composite sizing is prepared, and hydrogenated sheep oil and hydrogenated castor oil have emulsifying properties under the action of tridecanol polyoxyethylene ether and monoglyceride, can beevenly mixed in the sizing, play roles in plasticizing and improve the sizing percentage of the sizing. When grease is added in an adhesive containing polar groups, grease molecules can destroy physical crosslinking points of adhesive macromolecules and make it impossible for the polar groups of the macromolecules to establish interaction and hydrogen bonds, original non-moving chain segments begin to move, the vitrification temperature of serosas is reduced, and the serosas become softer. Besides, intervals between grease molecules make cohesive force between adhesive molecules reduced, a serosa structure thus relaxes, the strength is reduced, meanwhile the adhesive molecules are kept from fully moving close to fiber due to isolation of the grease molecules, and the desizing percentage ofthe sizing can be effectively improved.

Description

technical field [0001] The invention relates to a preparation method of grafted starch composite gelatin protein slurry, which belongs to the technical field of textile materials. Background technique [0002] Textile sizing is divided into two categories: adhesives and sizing aids. Adhesives are the main raw materials for sizing and determine the sizing performance of the sizing, while sizing aids can improve certain performance defects or deficiencies of adhesives. Grease, also known as wax flakes, is the most widely used type of auxiliaries in sizing auxiliaries. The use of grease for sizing can effectively reduce the friction coefficient of the yarn surface, reduce the warp yarn breakage rate during weaving, and improve weaving efficiency. Fat, also known as higher fatty acid glyceride, is a complex mixture, which is the general term for oil and fat. Glycerides containing a large amount of unsaturated fatty acids are liquid oils at room temperature; glycerides containi...
