| Summary: | The main purpose of this study is to develop a green dyeing process using Corchorus olitorius dye extract. Corchorus olitorius leaves were used as a new dyestuff source that has never been used for cotton fabric dyeing. Dye extraction was performed using a non-conventional clean process containing ethanol in an ultrasound bath. The extracted dye was applied to cotton fabric in a bath exhaustion process. The effect of dyeing parameters on the color strength of dyed fabric was studied. A response surface methodology design was used to optimize the dyeing process. The results showed that pH, dyeing temperature, and dyeing time significantly affect the dyed fabric. The optimum dyeing parameters were found at 90°C in a bath pH of 9 for 90 min. Finally, to improve the color strength, and the color-fastness, three mordanting processes, and three different mordants were used. Results show that pre-mordanted dyed cotton fabric using aluminum potassium sulfate produces the best fastness properties. |
