Polyacrylamide is a general term for acrylamide homopolymer or polymer copolymerized with other monomers, and is one of the most widely used water-soluble polymers. It is a hard glassy solid at room temperature, and its products include glue, latex and white powder, translucent beads and flakes. With the gradual development of the current society, polyacrylamide is more and more widely used in various fields, so what are its applications in the printing and dyeing industry?
1. In the textile industry, polyacrylamide flocculants are used as sizing agents and finishing agents for fabric post-treatment, which can form a soft, anti-wrinkle and anti-mildew protective layer.
2. When used as printing and dyeing auxiliaries, it can make the product have high adhesion fastness and brightness, and can also be used as a non-silicon polymer stabilizer for bleaching.
3. Polyacrylamide as a post-treatment agent can prevent static electricity and flame retardancy of the fabric.
In summary, polyacrylamide can be used as sizing agent, finishing agent, printing and dyeing auxiliary and treating agent in the printing and dyeing textile industry, and has a good purification effect in the wastewater discharge. It can not only be used in printing and dyeing industry, but also widely used in oil exploration, water treatment, textile, paper making, mineral processing, medicine, agriculture and other industries.
