Abstract

The invention discloses a sizing agent formula for medium-temperature sizing of pure cotton warp yarn. The sizing agent is prepared from medium-temperature dissoluble starch and a polyacrylic acid sizing agent. The invention also discloses a sizing method for the medium-temperature sizing of the pure cotton warp yarn. The sizing method comprises the following steps: respectively weighing the medium-temperature dissoluble starch and the polyacrylic acid sizing agent, and adding the medium-temperature dissoluble starch and the polyacrylic acid sizing agent into water in turns, thus preparing a size solution; then inputting the prepared mixed size solution in a size vat of a sizing machine, and starting the sizing machine according to a normal driving program so as to size the warp yarn. The sizing agent disclosed by the invention has the beneficial effects that the sizing agent formula is simple and is just prepared from the medium-temperature dissoluble starch and the polyacrylic acid sizing agent, size mixing is easy, the management is convenient, the warehouse area is effectively saved, and a less-component development trend of the sizing gent formula is accorded. Pure cotton yarn sized by the sizing agent formula and a sizing technology is capable of meeting weaving requirements, and the working environment of workers in a sizing workshop is remarkably improved; the production cost of an enterprise is obviously reduced through medium-temperature sizing, and the market promotion prospect is very good.

Description

technical field [0001] The invention belongs to the technical field of textile warp yarn sizing, and in particular relates to a slurry for medium-temperature sizing of pure cotton warp yarns; the invention also relates to a sizing method for medium-temperature sizing of pure cotton warp yarns. Background technique [0002] During the weaving process of the warp on the loom: first, it must withstand periodic and repeated tensile loads; second, the warp must undergo periodic and repeated friction. Therefore, the warp yarns are all sizing before weaving. Sizing is a composite material formed by the warp yarn and the size between the fibers soaked in the warp yarn and the size coated on the surface of the warp yarn. Only the warp yarns through sizing can be weaved, and weaving can be completed on the loom. Different sizing and warp combinations have different properties such as stretching, buckling, and wear resistance under different temperatures and humidity. [0003] The m...
