AI Technical Summary

Problems solved by technology

However, there are some defects in the performance of starch. The size film is brittle and hard, the elongation is small, the adhesion to hydrophobic fibers (such as polyester) is poor, the viscosity of the slurry after slurrying is high, and the stability is poor. The viscosity of the slurry is used for a long time. Large changes affect the quality of sizing, improve performance through starch denaturation, and better complete warp sizing

Abstract

A modified starch slurry is composed of the following raw materials in parts by weight: 15 to 22 parts of native starch, 8 to 14 parts of carboxymethyl cellulose, 7 to 12 parts of acrylamide, 6 to 9 parts of polyamine polyamide epoxypropane, 22 to 28 parts of modified starch, 0.5 to 1 part of potassium hydroxide, 4 to 8 parts of guar gum, 5 to 7 parts of hydroxypropyl distarch phosphate, 6 to 14 parts of butyl acrylate, 5 to 11 parts of ammonium persulfate, 4 to 6 parts of methyl methacrylate, 4 to 6 parts of modified tamarindus powder, 8 to 11 parts of protein slurry, and 5 to 6 parts of sodium alginate. The provided modified starch slurry has a greatly improved film-forming performance; moreover the adhesiveness, miscibility, and gelation are all improved, the reaction efficiency is high, and the pollution is little.

Description

technical field [0001] The invention relates to a modified starch size. Background technique [0002] With the enhancement of people's awareness of environmental protection, not only have higher requirements for the performance of textile pulp, but also require that the pulp has little or no pollution to the ecological environment when it is reproduced and used, which meets the requirements of environmental protection and is beneficial to human health. , do not endanger human life safety; in the process of production and use of slurry, energy and water sources should be saved; non-renewable resources should be used less or not, and renewable resources should be used to the maximum extent. Starch is a natural high-molecular polymer and a renewable substance with the most abundant sources in nature. It is degradable and will not pollute the environment. It consists of two parts, amylose and amylopectin, and the end product of its hydrolysis is glucose. With the development o...
