Fluorescence Analysis of Detergency Mechanisms of Olive Oil on Single Cotton Fibers

In this article, the detergency mechanisms at the single fiber level were examined from the microscopic perspective. Unlike the previous research, we improved the traditional method to investigate washing mechanism. The washing situation of cotton fiber soiled by olive oil was observed by Inverted Fluorescence Microscope, and the effects of the surfactant LAS (0.5 g/L) and Lipase (0.5 g/L) were discussed. The results indicated that the oil was rolled up from the fiber after washing with surfactant LAS, and the oil was broken down into soluble substances in water by hydrolysis after lipase washing.
