SYNTHESIS AND CHARACTERIZATION OF REACTIVE DYES BASED ON 4-AMINO-N-(5-METHYLISOXAZOL-3-YL)-BENZENESULFONAMIDE AND THEIR DYEING APPLICATION ON VARIOUS FIBRES.
(Indian Society For Health And Advanced Research, 2022-11) Umrigar, Nikita H.; Patel, Bhavesh M.; Chauhan, Shital C.; Parmar, Ketan C.
A new series of cold brand reactive dyes (D1 to D12) were synthesized by the coupling of diazotized 4-Amino-N-(5- methylisoxazol-3-yl)-benzenesulfonamide with various cyanurated coupling components in good yield. These reactive dyes were confirmed by 1H NMR analysis and FTIR. The synthesized dyes have been applied to cotton, silk, and wool fibres. They exhibited a variety of color shades with good dept and informality on the fibres. % Exhaustion and % fixation of dyes were determined by using Glauber salt as a fixing agent at various temperature conditions.
