Detergency testing using five types of artificially soiled cloth and a Terg-0-Tometer was performed to investigate the influence of the liquor ratio on detergency. The laundry used in this study was sets of five types commercially available artificially soiled cloth (JIS C 9606, and EMPA101, 104, 116, 117) and white cloth of each soiled cloth. Each of these cloths had a certain percentage in the whole laundry. The liquor ratio was changed by adjusting the amount of wash water to the same wash load, or by adjusting wash load to the same amount of wash water. In the both cases, the detergency (Di%) decreased as the liquor ratio became small, and a linear ralationship was obtained by plotting the amount of soils in the wash water to the amount of soils on the all cloths (ZK/S of testing cloths + S K/S of white cloths after washing). The same result was obtained by performing detergency testing varying the number of soiled cloths under the constant liquor ratio, and these results lead to the conclusion that the decrease in the detergency under the low liquor ratio is mainly caused by the increase of the amount of soils carried into the wash water.
