Studies of Sustainable Washing System using Ultrasonic Waves

采用显微图像分析系统研究了洗涤剂水溶液中聚对苯二甲酸乙二醇酯、PET、薄膜中模型污染物的去除行为。结果表明，随着声压和温度的升高，去污力增大。氢氧化钠的加入增强了土壤的去除率。在十二烷基硫酸钠的存在下，油性污染物的去除率增加，而颗粒性土壤的去除率明显降低。提高声压可以提高织物的去污力。实验结果表明，超声波可用于纺织品洗涤。

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.
