혼합洗劑의 洗濯性과 세탁效率에 관한 연구

A Study on the Washing Efficiency and The Detergency of Mixed Detergents

The purpose of this study was to determine oily soil removal from cotton, polyester, cotton/polyester knitted fabrics at a range of wash temperatures and wash cycles with commercial home laundering detergents of similar formulations. Removal of oily soil was determined by measuring the whiteness of solied and washed fabrics. The whiteness has been measured on a color difference meter. Multiple regression analysis was used to estimate the relationships between the measures of oily soil removal. The results were as follows : Oily soil removal of the soiled cotton knitted fabric was influenced by washing temperature rather than by washing time and was occurred at the low temperature of 10℃ and 27℃ without great difficulties. Synthetic oily soil was more difficult to remove from polyester than from any other fabrics. The effect of washing at 49℃ was worse than that of washing at the lower temperatures in terms of energy efficiency of laundry.
