초음파 세탁의 원리 및 최적 세척 조건 연구

초록

Ultrasound produces cavitation bubbles and microstreams when generated inwater to clean dirty laundry without wrinkling. This study examined the conditions for theeffective 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 temperatureincreased from 2.7 mV to 5.1 mV, and 25 °C to 60 °C, respectively. The detergencyincreased 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 ultrasonicintensity of over 4.3 mV. The detergency also increased with the liquor ratio. Therefore,for effective ultrasonic washing, increasing the ultrasonic intensity is more effectivethan increasing the temperature. Moreover, the washing time should not be too long.
