Detergency is the removal in a liquid of unwanted substances (soils) from a substrate's surface. The effectiveness of soil removal depends on such factors as the type of detergent, the mechanical action during washing, and the type of substrate. Extensive testing determines the optimal detergent formulations and washing machine designs for removing soils from specific fabrics. A broad classification includes natural and artificial soils. The artifical soils are further subdivided into oily soils, fatty soils, particulate soils, and stains. The common methods for identifying and characterizing soils include visual examination, nondestructive analysis (using gravimetric, neutron activation, X-ray fluorescence, microscopy, and radiotracer techniques) and spectroscopy. The goals of detergency research and testing are to development specific methods and formulas for washing specific substrates, such as apparel fabric or carpets. 259 refs.
