Abstract: Today’s consumer is looking for both physical and emotional well-being. In recent years, enhancement of performance properties and imparting special properties to fabrics has become essential. One such smart technology for textiles is introduction of anti-microbial finishes which impart feeling of freshness and cleanliness to wearer. The micro-organisms that grow and thrive in warm, moist recesses of our clothing cause foul smell and morbidity. To make the garments suitable for intimate apparel and children’s clothing, it is important to make them antimicrobial by applying dyes or selected finishes. Some common natural dyes have been found to exhibit antimicrobial property due to presence of large amounts of tannins. Tannins have the property to bind the microbial proteins, thus inhibiting their growth. As naturally coloured brown cotton has tannin derivatives and heavy metal ions as an integral part of its structure, it was considered imperative to explore and compare the antimicrobial property of coloured cotton with conventional white cotton. The present study was an endeavour in this direction where effort was made to explore the inherent antimicrobial property of naturally coloured cotton. The antimicrobial property of conventional white and naturally coloured cotton was assessed through Optical density and Standard Plate Count Test. The analysis of variance (ANOVA) highlighted that naturally coloured cotton significantly resisted the growth of microbes S. aureus, B. subtilis, E. coli and C. albicans. Amongst the coloured cottons, brown sample gave higher resistance due to the presence of catechin and other derivatives. The conidia and hyphae of fungus was hydrolysed due to catechin attack on the cell membrane. It also resisted bacterial growth by damaging the bacterial membrane. Gram positive bacteria exhibited better resistance because of the bactericidal effect of tannins present in naturally coloured cottons.
