Abstract

The invention provides a polyacrylic acid spinning sizing agent; the spinning sizing agent is prepared from, by weight, 40-65 parts of ylate emulsion, 10-18 parts of starch, 2-8 parts of hydroxyethyl cellulose, 0.2-1.5 parts of hydrophilia inorganic nano-particles, 1-3 parts of antifoaming agent, and 100-160 parts of de-ionized water. The ylate emulsion is mainly prepared by polymerizing acrylic acid, vinyl acetate, ethyl methacrylate and butyl methacrylate. Every component in the ylate emulsion is collaborative to each other, and is low in viscosity and good in mobility; the serous coat is elastic and good in extensibility, and good for improving the wear resistance of a yarn; the thermal stability of the serous fluid is good; the water soluble rate of the serous coat is quick, and size is easy to return; after sizing, the enhancement rate of the sizing yarn is significantly improved; moreover, the preparation method is simple and suitable for the industrial application.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a textile size, in particular to a polyacrylic type textile size. Background technique [0002] During weaving, the warp yarn needs to be repeatedly rubbed, stretched, wound and impacted by the movement of the loom. In order to reduce the breakage rate and improve the weaving efficiency, the warp yarn must be sized before weaving. 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, part of the size is infiltrated into the sliver. Inside the yarn, increase the adhesion between fibers and increase the tensile strength of the yarn to adapt to the high tension and mid-beat-up in the weaving process, reduce end breakage and improve efficiency. ...
