Summary, etc. <p style="text-align: justify;">Woven cotton and silk fabric samples have been dyed with <em>Racinus communis</em> extract at optimized conditions of extract concentration, temperature, material - to - liquor ratio (MLR), alum concentration and treatment time, and then evaluated for their fastness properties following ISO standards, antimicrobial activity quantitatively against <em>Staphylococcus aureus</em> and <em>Pseudomonas aeruginosa</em> bacterial strains and wash durability. Central composite design and single-factor design have been used in the optimization process, and based on the lowest number of colony-forming units per milliliter, optimized values are selected. The results indicate that optimized extract concentration of 39%, dyeing temperature of 70ºC, alum concentration of 3g/L, MLR of 1:30 (silk) and 1:40 (cotton), and treatment time of 30min (silk) and 40min (cotton) lead to 99.84% and 99.78% bacterial count reduction against <em>Staphylococcus aureus</em> and <em>Pseudomonas aeruginosa</em> respectively for dyed cotton fabrics. However, for dyed silk fabrics, a more improved percentage reduction in the bacterial count of 99.88% and 99.83% respectively is realized against both bacterial strains. Retention of the antimicrobial activity of dyed fabrics is found to be more significant even after 5 washes. The fastness properties of rubbing, washing, light, and perspiration for both fabrics range from moderate to excellent.</p><p style="text-align: justify;"> </p>
