Abstract

The invention relates to a preparation method of an energy-saving and environmental-protection type textile slurry for sizing textile yarns, wherein the energy-saving and environmental-protection typetextile slurry is prepared by mixing and drying the following raw materials by weight: 40-90% of low-viscosity modified starch, 10-60% of a polyacrylic acid slurry added with an ultrafine particle inorganic material, 1-6% of a yarn sizing oil agent, and 0-3% of a defoaming agent. According to the present invention, the production process is simple, the use is simple, the non-environmentally-friendly PVA textile slurry can be completely replaced during the sizing of pure cotton, polyester cotton, hemp cotton, artificial cotton, tencel and other yarns through the matched use of the slurry and the modified starch slurry, the manufacturing requirements of high-grade varieties and low-medium varieties are met, and the sizing cost is reduced.

Description

technical field [0001] The invention relates to the field of textile weaving, in particular to an energy-saving and environment-friendly textile size used for sizing textile yarns. Background technique [0002] China is a big textile and weaving country. Textile yarn sizing is an important part of textile and weaving. [0003] Weaving enterprises have introduced advanced air-jet looms, and used a large amount of PVA size in order to improve the quality of sizing, especially in high-end varieties. PVA size is not only costly, but the size film is strong and difficult to separate yarns, and the adhesion is poor and the weaving efficiency is low. [0004] , and the high COD content is difficult to degrade and is not environmentally friendly. According to the national survey of pollution sources, among 39 industries, the textile industry ranks in the forefront of COD emissions, accounting for 18.53% of the country's total. 55% of them are caused by printing and dyeing desizin...
