Cationic dyes,also known as basic dyes,are water-soluble dyes characterized by their positively charged molecular structure.This unique property allows them to form strong electrostatic bonds with negatively charged fibers. Cationic dyes are particularly suitable for dyeing and printing polyacrylonitrile fibers (Acrylic),and can also be applied to modified polyester,cationic dyeable polyester(CDP),paper and leather etc.
