ANSTRACTUltrasonic (US) radiation has a promising effect in textile processing due to its eco-friendly nature, rapid, cost and time effective tool. For the present study, the cellulosic fabric and dye solution were irradiated with ultrasonic (US) radiation for different times (10-60min.). Dyeing was performed using nonradiated and irradiated cellulosic with nonradiated and irradiated Reactive Yellow 145 dye. Different dyeing parameters such as temperature, pH, material to liquor ratio and time were optimized using irradiated dye and irradiated cotton. It is found that US treatment of dye solution for 20minutes gives good color strength by dyeing un-irradiated fabric at 70 degrees C, for 35min using dye bath of pH 9 in the presence of 5g/100mL of salt as exhausting agent keeping 40mL of dye volume. Colorfastness properties of fabrics dyed at optimum condition of various shades show that US treatment has improved the grading of fastness from fair to good. It is found that US irradiation had not only enhanced the strength of dye on irradiated fabric but also improved the dyeing properties. It is also concluded that US treatment has not only reduced the dyeing time, temperature but also reduced the amount of salt and dye volume used, which is the proof that this tool is cost, time and energy effective.
