Cationic dye - Characteristic

Cationic dyes generate colored ions with positive charges in the solution, and form salts with acid-base anions such as chloride ions, acetate roots, phosphate roots, methyl sulfate roots, etc., so as to dye polyacrylonitrile fibers. In practical dyeing, cationic dyes are commonly used to form a specific color. However, cationic dyes are often difficult to dye the same color, resulting in spots and layers. So in the cationic dye production, in addition to expanding the variety and quantity, but also pay attention to the dye variety matching; In order to prevent dyeing flowers, attention should be paid to the development of good levelness, in addition to improve the cationic dyes vapor fastness and fastness to light.
