| Abstract | ||
| The current study presents a straightforward and effective method for synthesizing a new yellowish-brown dye derived from a rhodanine compound. Various factors were examined in detail, including the influence of dyeing temperatures, dyeing durations, the pH of the dye solution, certain additives, and concentrations, as well as the fastness properties of the dyed samples. The effectiveness of these dyes in dyeing silk, wool, and nylon fabrics was demonstrated. Fourier Transform Infrared Spectroscopy (FT-IR) analyses were conducted on both undyed and dyed fabrics. Additionally, the antibacterial activity of the dyed materials was evaluated against Gram-positive bacteria (Staphylococcus aureus), Gram-negative bacteria (Escherichia coli), and the pathogenic yeast (Candida albicans). The dyed wool and nylon fabrics exhibited good antimicrobial activity against all tested microorganisms, with effectiveness percentages ranging from 48% to 93% in optical density. Notably, the dyed fabrics showed the highest antimicrobial activity against Candida albicans. Among the materials tested, the wool fabric demonstrated superior antibacterial properties compared to both nylon and silk fabrics. | ||
