Problems solved by technology

Acrylic size, together with starch size and polyvinyl alcohol (PVA) size, is listed as the three major sizes for textile use. Among them, starch is a natural polysaccharide polymer with good film-forming properties and affinity with natural fibers. Strong and easy to desizing; but starch size sizing is not strong enough, not wear-resistant, and has insufficient affinity with polyester fibers; polyvinyl alcohol size film is strong, flexible, and fluidity is good, but polyvinyl alcohol Difficult to desizing, and great environmental pollution; polyacrylic acid size is a general term for homopolymers, copolymers and blends of acrylic monomers, with low viscosity, good fluidity, and good adhesion to synthetic fibers It can be mixed well with starch and PVA size, and is suitable for warp sizing of various fibers, but the high price of polyacrylic acid size pushes up printing and dyeing enterprises

Abstract

The invention belongs to the technical field of textile sizing agent, and relates to an environmental protection type starch textile sizing agent and a preparing method thereof. The textile sizing agent is prepared from, by weight, 40-60 parts of modified starch, 5-15 parts of inorganic nanoparticles, 3-5 parts of organic silicon defoamer, 3-5 parts of animal fiber, 8-12 parts of proteinogenic amino acids, 3-5 parts of polyacrylic ester, 3-8 parts of inorganic mineral powder or 5-15 parts of acid amides, wherein the modified starch is the mixture of nano-silica modified starch and saccharifying enzyme modified starch, wherein the mass ratio of the nano-silica modified starch to the saccharifying enzyme modified starch is (20-30) : 1. Choosing the nano-silica modified starch and the saccharifying enzyme modified starch as raw materials to prepare the textile sizing agent makes the textile sizing agent easy to be degraded, thus the starch textile sizing agent is environment-friendly and pollution-free and has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of textile size, and relates to an environment-friendly starch textile size and a preparation method thereof. Background technique [0002] Today, the textile industry is developing in the direction of "green and environmental protection", and green pulp and green fiber are gradually being developed and applied to production. Warp sizing can improve the abrasion resistance of the yarn, reduce hairiness and improve the weavability of the yarn. Acrylic size, together with starch size and polyvinyl alcohol (PVA) size, is listed as the three major sizes for textile use. Among them, starch is a natural polysaccharide polymer with good film-forming properties and affinity with natural fibers. Strong and easy to desizing; but starch size sizing is not strong enough, not wear-resistant, and has insufficient affinity with polyester fibers; polyvinyl alcohol size film is strong, flexible, and fluidity is good, but po...
