Abstract

The invention discloses a textile assistant for sizing textiles and a preparation method thereof. The textile assistant comprises 50-200 parts of lignin, 50-200 parts of water-soluble monomer, 50-200 parts of oil-soluble monomer, 1-50 parts of water-soluble initiator, 0.05-5 parts of oil-soluble initiator, 400-1600 parts of water, 10-50 parts of dispersing agent, 500-2000 parts of low-viscosity starch with water content of 2-4%, 50-100 parts of alkaline matter and 1-30 parts of antifoaming agent. The preparation method comprises the following steps: putting matters with formulation dosages in a reaction kettle for reacting, and uniformly mixing an obtained grafted copolymer with the low viscosity starch, the alkaline matter and the antifoaming agent in a mixing machine so as to obtain the textile assistant. By adoption of the invention, the environmental load is beneficially reduced, the production efficiency is improved, the production cost is beneficially lowered, the adhesive power is proper and the serosa flexibility is good.

Description

technical field [0001] The invention relates to a textile size, in particular to a textile auxiliary agent for textile sizing and a preparation method thereof. Background technique [0002] The size coats the surface of the sliver with a layer of smooth, wear-resistant, flexible and strong size film, so that the winding fibers on the surface of the sliver are close to the backbone of the sliver, reducing the friction coefficient of the surface of the sliver, and at the same time allowing part of the size to penetrate Inside the yarn, it can increase the adhesion between fibers and increase the tensile strength of the yarn, so as to adapt to the high tension and medium beating-up in the weaving process, reduce the breakage and improve the efficiency. [0003] With the development of textile size until today, it has been unable to meet the requirements of various yarn varieties and sizing processes. The traditional three major size systems PVA, polyacrylic acid, and modified s...
