What are the functions of polyacrylamide in the printing and dyeing industry?

Several key functions of polyacrylamide in the printing and dyeing industry: In the textile industry, polyacrylamide flocculants are used as sizing agents and finishing agents for fabric post-treatment, which can produce a soft, wrinkle-resistant, and mildew-resistant protective layer. Flocculant as a post-treatment agent, which can prevent fabric static electricity and flame retardant. When used as a printing and dyeing aid, it can make the product have high adhesion fastness and bright color, and can also be used as a non-silicone polymer stabilizer for bleaching. It can purify the sewage discharge of the printing and dyeing textile industry, which is the most important. The characteristics of printing and dyeing wastewater are also very obvious: The amount of printing and dyeing wastewater is large, and the water consumption per ton of textiles for printing and dyeing processing is 100-200 tons, of which 80-90% is wastewater. Textile printing and dyeing wastewater has the characteristics of large water volume, high content of organic pollutants, high alkalinity and large changes in water quality. It is one of the difficult industrial wastewaters to treat. Wastewater contains dyes, sizing materials, additives, oils, acids and alkalis, fiber impurities, sand substances, inorganic salts, etc. The key to coagulation treatment of printing and dyeing wastewater is to choose the appropriate flocculant. The flocculants commonly used in the treatment of printing and dyeing wastewater mainly include aluminum sulfate, iron sulfate and ferric chloride in the early stage, and cationic polyacrylamide in the later stage. These flocculants have good treatment effects on water-insoluble dye wastewater such as disperse dyes, reducing dyes, and sulfide dyes, and have high removal rates of COD and chromaticity. The main products of flocculant manufacturer Xinhuan Water Treatment are: White polyaluminium chloride (food grade), drinking grade polyaluminium chloride, industrial grade polyaluminium chloride, anionic polyacrylamide, cationic polyacrylamide, nonionic polyacrylamide, petroleum recycling polyacrylamide, oil recovery polyacrylamide, polyacrylamide, polymer flocculant polymer flocculation coagulant, polymeric ferrous sulphate, polymerized iron and aluminium chloride, and other water treatment chemicals.
