    The detergency has been evaluated mainly as the detergency against soils on the white cloth so far. However, there have arisen some cases in which the detergency has to be evaluated also against soils on the dyed cloth.
    In the previous report, the authors have devised a gray scale exclusive for the evaluation of detergency conformed to the gray scale for color fastness as one of steps in evaluation of the detergency, tried its use in achromatic specimens and achieved effective results.
    Accordingly, in this report, we have tried to apply that gray scale exclusive for evaluation on detergency as expanded to soils on the dyed cloth and then have deduced a calculated evaluation value ND#.
    This ND* value in conformity with a grade value on the gray scale for color fastness can be converted to percent evaluation value which has been used so far and thus is regarded to be used effectively as a new value of evaluation on detergency well corresponding to one's visual sense.

    The study was performed to make clear the influence of autoxidation of fatty soils on clothes to detergency. Refined lard and soybean oil were used as fatty soils which adhere to clothes during cooking tasks.
    The results obtained were as follows;
    1) Extraction of lard on cloths after autoxidation by aging was done with ethyl ether completely, but it was necessary to extract soybean oil with ethanol followed by ethyl ether.
    2) When aging temperature was 40°C, autoxidation of lard started at the beginning of aging. But that of soybean oil began about 10 days after the beginning of aging. Once autoxidation started, the rate of autoxidation of soybean oil was higher than that of lard.
    3) The detergency of lard on cotton cloths aged for 20 days at 40°C was lower than that without aging, but the reverse tendency was seen on polyester cloths. Soybean oil adhered to cotton and polyester cloths was hardly removed by washing after 20-day aging.
