  Abstract

This study investigates the coloration of bacterial cellulose (BC) using the animalderived natural dye lac with natural mordants such as pomegranate peel and grape seed. The effects of Al pre-treatment, dye concentration, dyeing solution pH, and dyeing temperature on the dyeability of BC were systematically examined. FT-IR analysis confirmed the formation of coordination complexes between lac and Al, demonstrating the presence of chemical bonding between them. FE-SEM images showed that some lac and Al were physically entrapped within the BC nanostructure. The application of bio-mordants was evaluated alongside metal mordants to assess color fastness properties. Samples treated with bio-mordants exhibited excellent fastness performance, with rubbing and dry-cleaning fastness rated between grades 4, 4–5, and 5. These findings demonstrate that the biomordant can be utilized as an environmentally sustainable and effective mordant.
