Abstract

The invention discloses an environment-friendly textile sizing agent and a preparation method thereof. The environment-friendly textile sizing agent comprises 30-40 parts of modified starch, 0.4-0.6 part of potassium pyrophosphate, 2-8 parts of polyethylene glycol terephthalate, 4-12 parts of polyacrylic acid textile sizing agents, 0.8-2.2 parts of urea, 6-10 parts of calcium chloride, 2-4 parts of bentonite, 1-3 parts of sodium lignin sulfonate, 1-3 parts of defoaming agents and 28-50 parts of deionized water. According to the preparation method, raw materials are heated, firstly mixed, secondly mixed, thirdly mixed, stirred, cooled and packaged to prepare the environment-friendly textile sizing agent. According to the textile sizing agent, the polyacrylic acid textile sizing agents replace conventional PVA (polyvinyl alcohol) sizing agents and are nontoxic, harmless, easily biodegradable and desized and ecological-friendly textile sizing agents, the polyacrylic acid textile sizing agents are matched with modified starch sizing agents, so that the textile sizing agent has high adhesion and wear-resistant effect on fibers such as cotton, polyester cotton, hemp, artificial cotton and natural silk, the sizing agent is good in stability and penetrability and free from laitance and stains, dry yarns and skein yarns are light, secondary hairiness is decreased, and good sized beam rate is increased.

Description

technical field [0001] The invention relates to the field of textile slurry, in particular to an environment-friendly textile slurry and a preparation method thereof. Background technique [0002] China is a big textile and weaving country. Textile yarn sizing is an important part of textile and weaving. The sizing process is complicated, and there are many types of textile sizing materials added, and the cost is high. With the development of the textile industry, textile enterprises have introduced advanced air-jet looms , in order to improve the quality of sizing, especially in the high-grade varieties used a lot of PVA size. PVA size not only has high cost, but also has a strong size film, difficult yarn separation, poor adhesion, low weaving efficiency, and high COD content, which 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 emis...
