Abstract
Ultrasound produces cavitation bubbles and microstreams when generated in
water to clean dirty laundry without wrinkling. This study examined the conditions for the
effective ultrasonic washing of fabrics. The ultrasonic power, temperature, washing time,
and liquor ratio were varied, and an oily soiled cloth was used to evaluate the detergency.
The detergency of ultrasonic washing increased as the ultrasonic intensity and temperature
increased from 2.7 mV to 5.1 mV, and 25 °C to 60 °C, respectively. The detergency
increased from 10 min to 20 min, but decreased after 40 min. The longer the washing time,
the greater the soil redeposition. The liquor ratio only affected the detergency at an ultrasonic
intensity of over 4.3 mV. The detergency also increased with the liquor ratio. Therefore,
for effective ultrasonic washing, increasing the ultrasonic intensity is more effective
than increasing the temperature. Moreover, the washing time should not be too long.
