Abstract

The invention discloses an environmentally-friendly spinning sewing yarn slurry. The environmentally-friendly spinning sewing yarn slurry is prepared from, by weight, 50-70 parts of modified starch, 4-6 parts of nano TiO2, 8-12 parts of modified polyacrylate, 10-18 parts of polyvinyl alcohol and 2-10 parts of an additive. The environmentally-friendly spinning sewing yarn slurry has better environmental protection property, no PVA is added, raw materials are easy to degrade, are green and are environmentally-friendly; the environmentally-friendly spinning sewing yarn slurry is good in abrasion resistance, stability and compatibility and easy to desize, a slurry film is flexible and smooth, the slurry can be used for replacing a PVA slurry, the yarn end breakage rate can be effectively reduced, and the production efficiency can be improved; the slurry is good in adaptability and has better adhesive power to cotton and linen and a variety of synthetic fiber yarn products, especially to polyester cotton yarns.

Description

technical field [0001] The invention relates to the field of textile sewing aids, in particular to an environmentally friendly textile sewing yarn size. Background technique [0002] Yarn sizing is a key link in textile engineering. The purpose of sizing is mainly to improve the wear resistance of yarn, reduce hairiness, increase the strength of yarn appropriately, and reduce elongation, so as to withstand the mechanical action of yarn in the weaving process. force and improve the weavability of the yarn. [0003] At present, there are many types of slurry, the slurry formula and slurry mixing process are relatively old, the components are diversified, and lack of standardization and scientificity. The yarn size in the prior art is mainly starch, polyvinyl alcohol (PVA) and polyacrylic acid. Starch is a natural polysaccharide polymer, natural and environmentally friendly, and easy to desizing, but the sizing strength of starch size is not strong enough, and it is not wear-...
