Natural dyes are environmentally suitable due to their ecology and minimum impact on the environment and pollution. It can be a substitute for chemical dyes, which have some serious concerns about the environmental impact. The objective of this study is to extract natural dyes from mango peel and apply them on three different fabrics (cotton, chief value cotton, and viscose) to compare which fabric is more suitable. Tannin extracted from tea leaves was used as a natural mordanting agent. Both dye and mordant were extracted using a hot aqueous extraction method. Results show that mango peel dye can be an effective and sustainable alternative to synthetic dyes with promising potential for application in textile processing. Moreover, the tannin extracted from tea leaves enhanced the dye's adherence to all three fabric types, which shows good color fastness and durability.
