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 strong affinity with natural fibers. , 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 is difficult Desizing, and great environmental pollution; polyacrylic acid size is a general term for homopolymers, copolymers and blends of acrylic monomers, which have low viscosity, good fluidity, and good adhesion to synthetic fibers , can be well mixed with starch and PVA size, and is suitable for warp sizing of various fibers, but the price of polyacrylic acid size is high

Abstract
The invention discloses a high-adhesive polyester-cotton special textile slurry. The textile size is composed of the following raw materials in mass percentage: sodium silicate content is 50-70%, white carbon black content is 5-20%, carboxymethyl cellulose sodium CMS content is 10-15%, starch content is 5% -15%, the rest is a small amount of base reducing agent. The invention has wide adaptability, strong adhesion to cotton, linen and various synthetic fibers, especially polyester-cotton products, stable viscosity, easy sizing and desizing, and good compatibility with various starches; It can effectively reduce pulp and cotton waste, easy to split and twist, and reduce warp yarn breakage; it is environmentally friendly and reduces environmental pollution.
Description
technical field [0001] The invention relates to a high-adhesive textile size, in particular to a special high-adhesive polyester-cotton textile size. The invention also provides a preparation method of the high-adhesion 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 (PVA) size,...
