| Research Abstract |
The removal behavior of model contaminants from poly(ethylene terephthalate), PET, film in aqueous detergent solutions was examined using a microscopic image analysis system. It was found that the detergency increased with increasing sound pressure and temperature. The soil removal was enhanced by the adding of sodium hydroxide. In the presence of sodium dodecyl sulfate, the removal of the oily contaminants increased, whereas that of particulate soils considerably decreased. The detergency of the soiled fabric was enhanced by increasing sound pressure. The experimental results in this study showed that ultrasonic waves can be utilized to textile washing.
