Reactive dyes represent the most versatile and widely used class of colorants for cellulosic fibers like cotton, viscose, and linen. Unlike dyes that rely on physical entrapment or weak intermolecular forces, reactive dyes contain a highly reactive functional group (such as vinyl sulfone or chlorotriazine) that forms a permanent, covalent chemical bond with the hydroxyl groups of the cellulose molecule under alkaline conditions.
This chemical integration into the fiber polymer matrix gives reactive dyes exceptional washfastness and good lightfastness, ensuring that the colors do not easily bleed or fade during laundering. They are applied in a multi-stage process involving exhaustion with salt, followed by fixation using an alkali like soda ash. Reactive dyes provide bright, clean shades and excellent leveling, though a thorough “soaping off” wash sequence is mandatory to completely remove any hydrolyzed, unbonded dye from the fabric surface.
