People use variety of methods to wash clothes. Usually after adding soap, they beat the clothes on a stone or beat it with a paddle scrub or agitate the mixture in washing machine. Why is this agitation necessary to get the clean clothes?
It is necessary to agitate to get clean clothes because the soap micelles which entrap oily dirt on the surface of dirty cloth have to be removed from its surface. When the dirty clothes are agitated in soap solution, the oily dirt particles entrapped by soap micelles get dispersed in water and the clothes get cleaned.
