Popis: In the past few years, small household devices have appeared on the market for ultrasonic cleaning of textiles. In this study, the focus is on devices that can be immersed in a water tub for cleaning textiles by ultrasonics. These new devices were tested to see if they presented an opportunity to save electrical energy. Cleanliness levels were judged by comparison to conventional programs in household washing machines. The two devices tested demonstrated a higher effect than soaking without ultrasonics but a lower effect than any wash program. To get a better overview of what ultrasonics were capable of, additional experiments were conducted, i.e., in an ultrasonic bath for cleaning metal parts. It had a higher ultrasonic intensity and showed that there was still potential to get a higher cleaning effect for textiles at a low energy consumption level. It is concluded that, as far as household washing is concerned, ultrasonic treatments provide opportunities for the reduction of energy demand in low-temperature washing programs with a small textile load.
