Synthesis, Characterization and Dyeing Behaviour of Heterocyclic Acid and Mordent Dyes on Wool and Silk Fabrics

In the field of dye industries, heterocyclic compounds can play the important role to synthesis the various acid and mordent dyes which can give the variety of shades to different fabrics. Here, new heterocyclic acid and mordent acid dyes were synthesized by the coupling of diazonium salt solution of different aromatic amines having acidic groups with derivatives of dihydrobenzofuran and the obtained heterocyclic acid dyes were analyzed by various spectral techniques and the dyeing assessment of all the dyes was evaluated on wool and silk fabrics and the dyeing of chrome pre-treated wool and silk fabrics showed better shades on mordented fabrics due to chrome complex and it shows good shades with excellent depth and level ness and the dyed fabrics showed excellent fastness properties.
