| Outline of Final Research Achievements |
The detergency of polyethylene terephthalate films and polyester fabrics in an aqueous solution was investigated using a commercial ultrasonic cleaning apparatus operating at 38 or 130 kHz. The model contaminants, carbon black (CB) and oleic acid (OA), were used. It was found that the detergency at 38 kHz was higher than that at 130 kHz for the same electric power. The particles smaller than 0.6μm were easily removed at 130 kHz. The detergency of fabrics was found to enhance in the presence of NaOH and SDS. The effect of the exposure direction of ultrasonic wave and uneven washing was investigated using a self-developed ultrasonic cleaning apparatus operating at 38 kHz. The results showed that the detergency of film and fabric irradiated from bottom of wash bath was slightly high and the uneven washing was related with detergency.
