Abstract
A washing method was developed to import beneficial mechanical effects to sheets of soiled cotton fabric, fabric deformation clash of the fabric against wire gauze and penetration of a liquid flow through the fabric. This method consists in pulsating flows of through the fabric placed between two wire gauzes set in a cylinder.
Detergency was shown by this method to be about two times that possible by a commercial washing machine. The detersive efficiency was correlated to the product, (clash pressure) (frequency). Only half the amount of detergent was necessary to obtain the same degree of detergency as that by a commercial washing machine. Analysis of the experimental data clarified the effects fabric deformation fabric, its clash against the wire gauze and penetration of a liquid flow through the fabric on total detergency.
