| Popis: | The present study involves the aqueous extraction of dyes, optimization of dyeing conditions (Extract concentration and dyeing temperature), application of extracted dyes onto cotton fabrics using optimized conditions, SEM analysis of treated fabrics, assessment of their antibacterial activity, and wash durability. Using Central Composite Design (CCD), the optimized dyeing conditions were selected as 39.14 percent and 700C based on the lowest bacterial count demonstrated by the dyed cotton fabric samples. Results of Analysis of Variance (ANOVA) confirmed that extract concentration has a more significant statistical influence compared to dyeing temperature. Treated cotton fabrics at optimized conditions together with alum as a cross-linking agent exhibited a 98.54 and 97.96 percent reduction in the bacterial count against Staphylococcus Aureus and Pseudomonas Aeruginosa bacterial strains respectively. The retention of the antimicrobial activity of treated fabrics was found to be more significant even after 5 washes thus confirming that Galinsoga Parviflora extract is a potential source of finishes capable of improving antibacterial resistance of cotton fabrics for a longer period. |
