Abstract
To establish an effective washing method, experiments were conducted on an alternating flow system to bring about the flow through fabric material and the deformation of fabric. Air was introduced into an alternating flow so that less detergent would be required for washing. Examination was made of, concentration of detergent, washing time, and the effect of the amount of air on detergency. By applying the present method to the washing solutions of concentration over c.m.c, it was clearly shown the possibility of decreasing the amount of detergent as much as 50 % with no reduction in detersive efficiency. It was also shown that the detersive efficiency is related to the dynamic surface tension.
