Washing process seems to consist of two factors, pyhsico-chemical action of detergent and mechanical action of washing machine. In this paper, the effect of these factors on detergency was investigated by means of Terg-O-Tometer. Ratios of DC and DM to detergency, p and q, were shown as follows; D=DC+DM DM=DW 4; p= (DC/D) ×100= {(D-DM) /D} ×100= {(D-DW) /D} ×100 q= (DM/D) ×100= (DW/D) ×100 Where, D, DC, DM and DW are detergency, detergencies of physico-chemical action, mechanical action and of washing with water, respectively. It was found that logarithms of mechanical action and washing time were proportional to detergency in the case of washing with detergent soln. In the ordinary washing conditions p values showed 40-50% and q was 60-50%. Therefore, DM contributes to detergency in washing process, nearly as much as DC. Both washing temperature and concentration of detergent gave little influence on p values within litmit of the experimental conditions.
