With non-ionic monomer acrylamide copolymer, cationic, high molecular weight, with electric neutralization and strong adsorption bridging effect, so used for polyester, acrylic, polypropylene, cotton, polyester/wool, polyester/cotton and other synthetic fibers in the spinning process of electrostatic removal and dyeing finishing. It can effectively accelerate the speed of charge escape on the fabric, so as to generate less static electricity, and can make the fabric has the antistatic property of multiple times, at the same time, it has a strong effect on the processing and wearing suitability of the fabric.
