A simple, straightforward method, utilizing the concepts of classical adiabatic calorimetry, for direct measurement of total energy delivery to bench scale clothes washing systems is described. The results of such measurements can be expressed in conventional work units such as calories per unit weight or per unit area of fabric. Using this method, total energy input is measured and related to soil removal in model wash systems using a standard cotton soil cloth. The relationship between energy input and soil removal is considered for a number of situations involving variations in stroke rate, load weight and detergent concentration. Finally, these results are used to develop a modified definition of detergency which places the emphasis on the efficiency of mechanical energy utilization in a soil removal process.
