| Abstract: | Ecru denim swatches were dyed with onion extract using potassium alum in combination with natural mordants harda and tartaric acid. Potassium alum-harda combination was found to be better than potassium alum-tartaric acid combination. Among the three mordanting methods, the meta-mordanting produced the best results for both the mordant combinations. Synergistic effect of mordants was observed while using the binary combinations of mordants. There was an overall improvement in performance properties of the samples dyed with various combinations over that of the single-mordanted and the control samples. The samples post-mordanted with potassium alum-tartaric acid (5:5) after dyeing showed the best fastness properties among all the substrates. |
