Problems solved by technology

[0007] The disadvantage of the existing method is that a large amount of steam is required to boil the pulp and maintain the temperature of the pulp during the sizing process, the pulping efficiency is low, the sizing efficiency is not high, and the solid content of the pulp is not high and can only be controlled at 8-15%. During drying, a large amount of steam is required to remove moisture, and the amount of steam used is astonishing

Abstract

This invention refers to a warp sizing craftwork to fabric in weave industry. A direct processing warp sizing method used amylum latex includes brewage serosity and warp sizing steps. Its trait is 1) Brewage serosity, (1) the stuff selection, prepare, the stuff include amylum, polypropylene and exterior activator, the polypropylene is 1~10% of amylum dry weight, the exterior activator is 0.1~5% of stuff weight. (2) Serosity brewage. First, immit 3-5 times water of amylum bulk, then immit amylum to the conditioning, beat up enough to suspended latex. 2) Warp sizing. The warp dip the amylum latex of above slash box, the sizing let the amylum grain absorb yarn. The slash box keep the temperature of 20~35oC, the warp after sizing is through cylinder, felt the amylum paste on the fiber, meanwhile, realize sizing. This invention reduces the cost of sizing.

Description

technical field [0001] The invention relates to a sizing process for warp yarns of woven fabrics in the textile industry. Background technique [0002] At present, the sizing process of woven fabrics is mainly divided into the following two steps: figure 1 shown, [0003] Step 1: Prepare the Slurry [0004] According to the production process requirements, put starch, polyvinyl alcohol, polyacrylic acid slurry and other auxiliary sizing aids (such as surfactants) into the sizing barrel in the proportion required by the production process, then add water and stir and heat up to cook the slurry. After gelatinization, keep the temperature at about 95℃ and simmer for 1-1.5h. If the amount of polyvinyl alcohol to be added is large, the polyvinyl alcohol needs to be boiled in the high-pressure pulping kettle first, and then put into the pulping barrel for mixing (this takes 1 to 2 hours). [0005] Step 2: Warp Sizing [0006] After the sizing is boiled, put it into the sizing...
