Antibacterial Efficiency of Naturally Occurring Dyes and Mordants

Abstract

The popularity of natural dyes is increasing day by day due to their properties such as soothing colors, non carcinogenic, non hazardous and safe for environment. Some natural dyes also have been reported antibacterial properties. In present research work flowers of Butea monosperma and Tagetes erecta were used for dye extraction. Banana pseudostem sap and Punica granatum rind taken as biomordant. High performance thin layer chromatography was conducted for identification of components of Butea monosperma, Tagetes erecta, Banana (Musa sp.) pseudostem sap and Punica granatum rind. Dyeing of two types of cotton fabrics performed at pre-optimized conditions. The antibacterial activity of dyed fabrics was evaluated quantitatively and qualitatively. Research finding supported the usage of Butea monosperma, Tagetes erecta, Banana (Musa sp.) pseudostem sap and Punica granatum rind in textile dyeing process.

“…is on the way. 11,23 However, these colors have some issues such as poor strength and low fastness ratings. 24 Previously, scientists are using conventional methods to improve the colorant strength, and are using chemical mordants to improve fastness ratings.…”
