ULTRASONIC DYEING OF COTTON FABRIC WITH AQUEOUS EXTRACT OF TERMINALIA ARJUNA.

Conventionally the dyeing of natural dyes from plant materials was done by boiling which requires longer time, higher temperature and metallic mordant to get good color fastness. Use of metallic mordants for dyeing posed some cruel effect to ecosystem. This study explained a suitable technique for more efficient natural dyeing using suitable mordant to improve the color fastness of natural dyes on cotton fabric. This study demonstrated ultrasonic cleaner as a technique of dyeing the colorant from a Terminalia arjuna was dyed at different ultrasonic volume and time. Results show the highest percentage of dye absorbed to cotton fabric using ultrasonic cleaner was produced at optimum condition of medium sonic volume in 80 minutes time. The utilization of ultrasonic cleaner was found to have significant improvement in the dyeing color of natural dyes to cotton fabric with lower dyeing temperature compared to traditional method.
