• Cotton garments were coated with small particles. Liquid paraffin, Triolein and Oleic Acid organic soils served as the sources of produced with human wear. The clothing with titanium dioxide was immersed in aceton solutions of these compounds, withdrawn and irradiated with UV from a low pressure Hg lamp. Spectral reflectance was then measured with a spectrograph and found to increase at more than 400 nm. Detergency and reflectance decrease at less than 400 nm were assessed following irradiation at both these wavelengths, and was found, respectively to be positive and negative. Without titanium dioxide, negative detergency was observed. From these results it may be recognized that changes in model soil materials were occurred by photo catalytic action of titanium dioxide.
