| Abstract | ||||
| PNew techniques of extraction of natural dyes such as ultrasonic extraction, microwave extraction and utilization of enzyme are these days broadly being investigated for their high effectiveness over the traditional techniques.Ultrasonic or microwave techniques succeeded in accelerating the rate of, extraction at lower temperatures rather than the conventional heating technique. Ultrasonic power or microwave represents promising techniques for assisting extraction processes in comparison with the conventional heating technique. As plant tissues include cellulose, starches, and pectins, economically accessible enzymes such as; cellulase, amylase, and pectinase have been utilized to release the surrounded material prompting to the extraction of colourant particles in reasonable terms. Utilization of ultrasonic and enzyme for textile treatment additionally been examined and it has been announced that consolidated ultrasound and enzyme treatment augmented extraction yield marginally, however it reduced the time and temperature of treatment. | ||||
