Reactive Dyes come from class of highly colored organic substances that find application in tinting of textiles. These work by attaching to substrates through chemical reaction, thus forming covalent bonding between molecule of dye and fiber. This process makes dyes used as part of fiber and has stronger resistance for removal by washing.
Chemical bounding of reactive dyes to textile fibers also highly improve product''s color stability and wash-ability
Finding extensive usage in the dyeing of cotton
Works by forming covalent bonds with substrate that needs to be dyed that allows permanent wash proof bonding with cellulose of cotton fiber
