  Abstract

In pursuit of improving dyeability and incorporating antimicrobial attributes into polyamide fabric, a series of mono-azo acid dyes (SN1–SN5) were synthesized. Sulfathiazole was employed as an intermediate in the synthesis process of the dyestuff. The resultant dyes were characterized by employing various analytical techniques. The antimicrobial efficiency of these colorant was established through testing against Aspergillus fumigatus, Staphylococcus aureus, and Escherichia coli, displaying a spectrum of mild to strong antibacterial activity. Dye SN5 exhibited the highest potency, showing growth inhibition of 90% and 95% against both bacterial strains, respectively. Since the acid dyes are the prime contenders for utilization in food, pharmaceuticals, and cosmetics, an assessment was conducted on BJ Human Fibroblast Cells to evaluate any plausible adverse impacts. The results revealed that all the dyes exhibited no cytotoxicity. The dyeing properties of these colorants, including color representation, build-up, exhaustion, and fixation, were thoroughly examined following their application on the fabrics. The fastness properties were found to be considerably good to excellent. The influence of acidic and alkaline conditions on the absorption maxima was also explored. The dye SN3 showed a substantial bathochromic shift with increase in the solution's acidity in comparison to other dyes.
