Basic Dyes
Cationic dyes (basic dyes) are named because they contain a quaternary ammonium cation in their molecules. Cationic dyes are usually bright in color and have good water solubility. They dissociate into cations in aqueous solution and are special dyes for acrylic fibers. Dyes with cations in their molecules also include basic dyes, which are some older dye varieties. Some of them can also be used to dye acrylic fibers, but the color brightness and dyeing fastness are inferior to cationic dyes. Due to habitual reasons, they are collectively referred to as basic dyes in the Colour Index.
Basic dyes are also known as cationic dyes. The cationic dyes can be combined with the acidic group of the third monomer in the fabric to make the fiber dyed. They are special dyes for acrylic fiber dyeing and have the advantages of high strength, bright color and good light fastness.
