Dyeing performance and antibacterial properties of four novels synthesized reactive dyes (D1–4) were studied in this paper. The dyeing process was achieved under a variety of conditions, embracing concentrations of the dye (1–9%), soda ash (0–25 g L−1), Glauber salt (0–100 g L−1), dyeing temperature (40–90 °C), dyeing time (30–90 min), and material to dye liquor ratio (1:05–1:80). The maximum color strength (expressed as K/S) values of the dyed cotton fabrics obtained at 3% (based on fabric weight, wof) dye concentration, 20 g L−1 sodium carbonate, 100 g L−1 Glauber's salt, temperature 80 °C (for D1, D2 & D4), and 60 °C (for D3), fixation time 60 min, and material‐to‐liquor ratio (M/L) 1:10. The fastness properties towards washing, perspiration, rubbing, and light were evaluated. All dyed fabrics showed antibacterial potency against both gram positive (S. aureus) and gram negative (E. coli) bacteria. [ABSTRACT FROM AUTHOR] |
