Natural dyes and mordants are increasing in demand due to growing environmental awareness among people. This study is focused on application of tannins extracted from tea as mordant on cotton fabric and dyed with henna. The extraction of tannins was done using a hydrous extraction process. For the extraction commercially available fresh and used tea leaves were used. Different parameters were studied to optimize the condition of mordanting cotton fabric with tea extract. Concentration, time and temperature were varied and then finalized based on visual evaluation and color fastness properties of these fabrics when dyed with henna. Both pre mordanting and post mordanting methods were used. The results produced with fresh tea tannin were better than fabrics mordanted with used tea tannin. Also the fastness properties of the henna dyed fabrics were found to be average to good.
