Abstract

The invention discloses a preparing process of a starch textile sizing agent. The sizing agent is prepared from, by weight, 30-40 parts of composite modified starch, 3-6 parts (such as 4 parts, 5 parts or 5.5 parts) of phosphate ester starch, 1-4 parts (such as 2 parts, 3 parts or 3.5 parts) of defoaming agent and 100 parts of deionized water. The process has the advantages that traditional PVA sizing agents are all replaced in the desizing process, the weavability of the product is improved, the sizing cost is reduced, and the subsequent desizing labor and wastewater processing cost are reduced; in addition, through the prepared phosphate ester starch, the color and luster are good, no yellowing phenomenon can easily happen, and certain market value is realized.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a preparation process of starch textile size. Background technique [0002] During weaving, the warp yarns are 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 yarns 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, it can increase the bonding force between fibers and increase the tensile strength of the yarn to adapt to the high tension and medium beating-up in the weaving process, reduce end breakage and improve efficiency. [0003]...
