Novel high-adhesion textile size special for polyester cotton

Abstract

The invention discloses a novel high-adhesion textile size special for polyester cotton. The textile size is prepared from the following raw materials in percentage by mass: 50-70 percent of sodium silicate, 5-20 percent of white carbon black, 10-15 percent of CMC, 5-15 percent of starch and the balance of a small amount of an alkalinity reducing agent. The textile size is wide in adaptability, has strong adhesion force for cotton hemp and various synthetic fibers, particularly polyester cotton products, is stable in viscosity, and is ease for sizing and desizing. The textile size has good intermiscibility with various starches, can effectively reduce size shedding and noil, is easy to lease, and reduces warp end breakage. The textile size is environmentally-friendly and reduces environment pollution.

Description

technical field [0001] The invention relates to a novel high-adhesive textile size, in particular to a special high-adhesive polyester-cotton textile size. The invention also provides a preparation method of the novel high-adhesive textile size, which belongs to the technical field of textile size size. Background technique [0002] At present, sizing is an important process in fabric production and a key factor to ensure the efficiency of looms, improve the quality of gray fabrics, and reduce warp breakage. Especially in the production of thick and extra-high-density polyester-cotton fabrics, high-frequency, small opening, large tension, and strong beating-up techniques are adopted in the weaving process. The frictional force, repeated stretching force and The bending force is particularly large. Therefore, only good sizing can improve the strength of the fabric in the case of warp yarns being greatly damaged. Acrylic size, together with starch size and polyvinyl alcohol...

AI Technical Summary

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 price of polyacrylic size is high
