| Abstract | ||||
| In recent years, the textile industry proceeds towards creation of new technologies to reduce the energy and water consumption. The use of ultrasonic in textile wet processing is one way to achieve that purpose. The present work investigates the effects of ultrasonic energy on dyeing of silk fabrics with Chlorophyll as a natural dye. Silk fabrics were dyed with Chlorophyll dye in an ultrasonic bath by the conventional exhaustion method. The parameters that affect the dyeing process, such as dye concentration, dye bath pH, salt concentration, and temperature, time and power energy ultrasonic values have been explored. Concentration of tannic acid was also studied as a mordant in the dyeing process. The results show that the color strength as well as fastness properties of the dyed silk fabrics were enhanced on using the ultrasonic technique compared with the conventional method in presence of 5% tannic acid. | ||||
