Synthesis of Reactive Dyes Containing Acrylamido Group and Their Application to Cotton Fabric

Three reactive dyes, viz yellow dye, red dye and orange dye containing acrylamido group were synthesiz ed and they were analyzed and characterized by HPLC, mass spectrometry and elemental analysis. These dyes were applied to cotton by exhaust dyeing process. Maximum performance of these dyes was observed using 20 g/l soda ash at 70 – 95 o C for 60 - 120 min. These synthesized reactive dyes showed good colour fastness properties indicating stable bond formation between acrylamido group and cotton fabric.
