Anionic polyacrylamide is a water-soluble high molecular polymer, which is mainly used for flocculation and sedimentation of various industrial wastewaters and precipitation clarification treatment.
Generally, anionic polyacrylamide is selected in the textile industry. The role of anionic polyacrylamide in the textile industry can be sizing agents, binders, lubricants, textile auxiliaries, dye leveling agents, textile wastewater treatment flocculants, and the like.
1, dyeing leveling agent
When anionic polyacrylamide is used as a printing and dyeing auxiliary, the adhesion of the product is high and the vividness is high. It can effectively improve the quality of dyed fabrics, and is used for the finishing of yarn-dyed products instead of latent water-soluble resins to improve the stiffness and elasticity.

2, textile sizing agent
In the textile industry, anionic polyacrylamide acts as a sizing agent and finishing agent to form a protective layer that is compliant, wrinkle-resistant and mold-resistant. It has the characteristics of strong hygroscopicity, which can reduce the breaking rate when spinning the spun yarn. The anionic polyacrylamide can be used as a post-treatment agent to prevent static electricity and flame retardant of the fabric.
3, stabilizer
Anionic polyacrylamides are also useful as bleached non-silicon polymeric stabilizers.
4, textile auxiliaries
Some other chemicals are added to make a chemical slurry for sizing of textiles, which improves the adhesion, permeability and desizing properties. The role of anionic polyacrylamide is to thicken, bond and lubricate. The textile has anti-static, reduces the sizing rate, reduces the smashing spot, and the machine breaks the rate and falls off. Can significantly improve the quality of the product.
Anionic polyacrylamide is used as a sizing agent for woven fabrics, a finishing agent, and a protective layer that produces a compliant, wrinkle-free, mold-resistant coating. With its high hygroscopicity, it can reduce the breaking rate when spinning the spun yarn. Polyacrylamide as a post-treatment agent prevents static and flame retardant of the fabric. When used as a printing and dyeing auxiliary, polyacrylamide can make the product have strong adhesion fastness and high vividness, and can also be used as a non-silicon polymer stabilizer for bleaching.
