Abstract
Laser Induced Fluorescence (LIF) method is one of the fluorescence analysis methods that are very excellent methods as one of the quantitative analysis of the material of a small amount. This paper describes a new evaluation method of adhesion soil in woven fabrics by using LIF Spectroscopy. LIF spectra were measured by a developed measuring system. There are a peculiar absorption peak and luminescence peak in the molecule. In this research, we used artificial sweat and artificial lipid as model soil of sample. Then we used cotton cloth, cupro cloth, rayon cloth as standard cloth of sample. Fluorescence intensity of each sample was measured, and the quantitative evaluation of the model soil was done based on fluorescence intensity. This paper also describes the grasp of the distribution situation of the model soil in two dimensions.
