Abstract

<p>The detergency of polyethylene terephthalate (PET) films in an aqueous solution was investigated using a commercial ultrasonic cleaning apparatus operating at 38 or 130 kHz. Carbon black (CB) or colored oleic acid (OA) were deposited onto the PET film. The PET film was ultrasonically cleaned in an aqueous sodium chloride (NaCl) solution with or without sodium hydroxide (NaOH) or sodium dodecyl sulfate (SDS). The detergency was calculated using the microscopic image analysis system. It was found that CB detergency at 38 kHz was higher than that at 130 kHz for the same electric power. Ultrasonic washing was also carried out using PET fabrics and the detergency was evaluated by the surface reflectance method. The detergency was found to enhance in the presence of NaOH and SDS. The effect of the exposure direction of the ultrasonic wave on the fabric detergency and uneven washing was investigated using a self-developed ultrasonic cleaning apparatus operating at 38 kHz.</p>
