Question

Describe the process ofWashing machine.

Answer 1

Washing machine works in the following way ,

There are two things going on in a washing machine. First is the chemical action of the soap or detergent. These substances reduce the surface tension of the water which causes it to wet the dirt and to emulsify the oils.

This action is aided and made much more effective by the agitation of the clothing in the washing machine. The agitation flexes the fibers and moves the detergent water into and out of the clothing fibers flushing out the dirt and emulsified oils.

Back in the very old days women would take clothes down to the river or stream rinse them and then beat them against rocks to provide the agitation. The only soaps available were lye soaps made from wood ashes and animal fats. It could be pretty harsh stuff.
