Reactive Dyes
Reactive Dyes are the most versatile and popular class of Organic Dyes for importing color on cellulosic fibres. As the name suggests, these dyes chemically react with cellulose to form a covalent bond between dye molecule and cellulose. Reactive site on dye reacts with functional group on the fibre to bind dye covalently under influence of heat and proper pH. Reactive dyes are unique as they are the only class of dyes that actually form a chemical bond with the textile fiber and this bond gives them their excellent wash fastness properties. Reactive dyes are used to cotton Rayon wool silk & Nylon.
