Warp sizing method

Abstract

The invention relates to a warp sizing method which comprises the following steps: step one, blending polysaccharide substances into a slurry at room temperature or medium temperature; step two, stirring and mixing evenly the slurry and polyacrylic acid in a room temperature or medium temperature slurry conditioning barrel to obtain a slurry; and step three, under the condition of room temperature or medium temperature, sizing warps with the slurry by a sizing machine. The method does not adopt PVA (polyvinyl alcohol), reduces the yarn sizing cost, also brings great convenience to next-step printing dyeing desizing, reduces desizing wastewater emissions, reduces a weaving workshop dust problem, allows workshop hygiene to be improved, greatly reduces the worker inhalation of PM2.5, and is conducive to environmental protection and operator body health; the slurry steam consumption is reduced, and energy consumption is reduced; the method completely abandons the status of use of a large number of grain starch in traditional sizing and is conducive to grain supply security; in short, the method has the advantages of energy saving, no use of PVA, reduction of dust falling, and easy desizing.

Description

Technical field [0001] The invention belongs to the technical field of textiles, and specifically relates to a method for sizing warp yarns. Background technique [0002] Warp sizing is an indispensable process in the textile processing process, and it is also an extremely complex and critical process. The purpose of warp sizing is to improve the weaveability of warp yarns, and the quality of sizing directly affects the level of weaving efficiency and product quality. Therefore, warp sizing is the most critical process in weaving production. [0003] At present, the sizing material is usually composed of starch, polyvinyl alcohol and other polymer materials such as gelatin, polyoxyethylene, carboxymethyl cellulose, etc. These materials are used for sintering with water at high temperature and high pressure, then sizing under high temperature conditions, and high pressure cooking. The temperature is 120 degrees, and the sizing temperature of warp yarns is (90-95 degrees). The disad...

Problems solved by technology

[0003] At present, the sizing materials are usually composed of starch, polyvinyl alcohol and other polymer substances such as gelatin, polyoxyethylene, carboxymethyl cellulose, etc., and the pulp is fired at high temperature and high pressure with water, and then sizing is performed under high temperature conditions, and the pulp is boiled under high pressure. The temperature is 120 degrees, and the warp sizing temperature is (90-95 degrees). The disadvantages of the above sizing methods are that it consumes a lot of energy for cooking pulp, takes a long time for cooking pulp, and the high pressure is dangerous. Not allowed, the size molecules are easy to degrade, the viscosity is unstable, and it is not resistant to high temperature fiber deformation (the problem related to the high temperature cooking and sizing method is the energy problem, the slurry water dispersion system is raised from room temperature to high temperature, cooking, heat preservation, sizing, It takes several hours during the period, consumes a lot of energy, and does not meet the current production requirements for energy saving and consumption reduction)
