| The present work examines the usage of willow extract as a natural mordanting agent during dyeing of wooden and fiber samples with onion (Allium cepa) shell as a natural dyestuff source under different conditions. The naked willow was cut into small pieces and allowed for 20 days in distilled water. At the end of the period, the solution was filtered and stored at room temperature until usage. The extraction of dyestuff from dried shell of onion was performed using soxhlet apparatus in distilled water. Cotton, wool, feathered-leather and wood samples were dyed using pre-mordanting, together mordanting and last mordanting methods at fix pH value (pH=4,5-5) in the presence of FeSO4.7H2O, AlK(SO4)2.12H2O and CuSO4.5H2O mordants. To investigate the best dyeing conditions, 9 wool, 9 cotton, 9 feathered-leather fibers, and 18 wood samples were dyed according to the methods that mentioned above. Before the dyeing experiments all the samples were first kept into willow extract for 24h and then they put into the Artifical Animal Urine System (AAUS) for 24h. The optimum dyeing conditions were determined and the importance of willow extract as a mordant agent was evaluated in terms of fastness of dyed samples. The results of the present study suggest that the use of willow extract is not only enhance the fastness but also increase the brightness of the dyed samples. |
