Abstract

The invention provides a polyacrylic acid textile pulp. The polyacrylic acid textile pulp is prepared from, by weight, 40-65 parts of polyacrylate emulsion, 10-18 parts of starch, 2-8 parts of hydroxyethyl cellulose, 0.2-1.5 parts of hydrophilic inorganic nano-partilces, 1-3 parts of a defoaming agent and 100-160 parts of deionized water, wherein the polyacrylate emulsion is mainly obtained by polymerizing acrylic acid, vinyl acetate, ethyl methacrylate and butyl methacrylate. All the components in the polyacrylic acid textile pulp are in synergism, and the polyacrylic acid textile pulp is low in viscosity and good in mobility; a pulp film is elastic, good in extensibility and beneficial to improving the wear-resisting property of yarns; the thermal stability of the pulp is good; the water dissolving speed of the pulp film is high, desizing is easy to achieve, the strengthening rate of sized yarns is remarkably increased after sizing, and the polyacrylic acid textile pulp is simple in preparing method and suitable for industrialized application.

Description

Technical field [0001] The invention belongs to the technical field of textiles, and relates to a textile slurry, in particular to a polyacrylic acid textile slurry. Background technique [0002] During weaving, warp yarns must be loomed to produce repeated friction, stretching, winding and impact. In order to reduce end breakage and improve yarn weaving efficiency, warp yarns must be sizing before weaving. The sizing agent coats the surface of the yarn with a layer of smooth, wear-resistant, flexible and strong sizing film, so that the winding fibers on the surface of the yarn are close to the backbone of the yarn, reducing the friction coefficient of the yarn surface, and at the same time, part of the slurry penetrates Inside the yarn, increase the adhesion between the fibers and increase the tensile strength of the yarn to adapt to the high tension and mid-beat weft during the weaving process, reduce end breaks and improve efficiency. [0003] There are three main types of text...
