Reactive dyes are a type of dye capable of forming covalent bonds with fiber molecules, such as cellulose fibers like cotton, linen, and viscose, or protein fibers like wool and silk. They exhibit excellent wet fastness and brilliance.

Acid dyes are a type of water-soluble anionic dyes, featuring a molecular structure containing sulfonic acid groups (-SO₃H) or carboxyl groups (-COOH), and are used for dyeing in acidic or weakly acidic media. They are primarily applied to protein fibers (such as wool and silk) and polyamide fibers (such as polyamide/nylon), and can also be used for dyeing leather, paper, ink, and other materials.
