Abstract
The current study targets to synthesize some new sulfonamido-hydroxythiophene dyes for dyeing polyester fabrics with estimated antibacterial activity. The structure of sulfonamide dyes was adapted by conducting with sulfadimidine and sulfamethaxole through the coupling reaction. The synthesized derivatives were established by spectroscopic tools (Fourier transform infrared spectroscopy, proton nuclear magnetic resonance). Hydroxy-thiophene-containing sulfonamides were utilized for dyeing polyester fabric. The prepared sulfonamido-hydroxythiophene dyes were applied on polyester fabrics after establishing the optimum dye conditions, and afterward their dyeing properties, light, washing, perspiration, rubbing and sublimation fastness were determined. Meanwhile, the improved dyes demonstrated respectable fastness results and antibacterial properties against some gram-positive and gram-negative bacteria.
