초음파 세탁과 가정 세탁의 세척성과 직물변형 비교

초록

In this study, the efficacy of ultrasonic washing in cotton and wool fabrics was compared and evaluatedagainst conventional washing in terms of cleaning properties and fabric deformation. Factors such as washing tem-perature, time, liquid ratio, and detergent concentration were kept varied, and the cleaning properties of sebum-soiledfabrics were assessed using different detergents such as alcohol ethoxylate, linear alkylbenzenesulfonate, and IEC60456 Reference Detergent A*. In addition, the effects and emulsification power of enzymes and oxygen bleach wereexamined. To compare the cleaning properties with general washing, a launder-O-meter was used. To investigate fabricdeformation during the washing process, the loosening test cloth, shrinkage test cloth, and mechanical strength testcloth were compared between ultrasonic washing machines and household drum washing machines. The results indi-cate that ultrasonic washing exhibits superior cleaning properties than launder-O-meter when the temperature is lowand the washing time is short. Furthermore, there is less deformation and damage during the washing process. It wasalso observed that the activity of the detergent increases when ultrasonic waves are applied to the washing process. Considering the increasing tendency to pursue convenience and simplicity in clothing management as well as the antic-ipated commercialization of smart clothing with built-in electric circuits, ultrasonic laundry could serve as a new alter-native to existing laundry methods.
