The relationship between the rates of felting and soil removal was investigated when wool fabrics were washed in domestic washing machines under various conditions of agitation, machine load, and foaming. It was shown that this relationship is a direct one for a particular detergent solution used in the machine. At higher loads, the rates of felting and desoiling are retarded, but the linear relationship is still maintained. Efficient soil removal with less felting can be ob tained by the selection of a suitable detergent.
