Abstract
Sustainable chemistry is a relatively new field that aims to achieve both economic and environmental goals simultaneously. This paper discusses a cleaner and more sustainable method for dyeing cotton fabric using Direct Violet 09 and Reactive Violet 05 dye. It has been noticed that good color characteristics were obtained when cotton fabric was dyed with 35 mL of microwave-treated Reactive Violet 05 dye solution of 7 pH and 2 g Aluminum sulfate for 30 min at 60 °C. When dyeing cotton fabric with Direct Violet 09 dye, it has been observed that cotton fabric, when microwave treated for 6 min and dyed at 80 °C for 50 min using 35 mL of non-treated dye solution of 7 pH with 2 g Potassium sulfate, produces good results. The colorfastness of the dyed fabrics using ISO standards was also evaluated. Overall, it was found that the use of microwave radiation improves the sustainability of the dyeing process.
