A new laundering method was presented by the author, which may be named provisionally as "Polymer-coated Laundering Method", and by this method, a higher detergency than ordinal laundering methods, i.e. immersion of soiled fabrics in a solution of detergent, was attained. And this method have projected many interesting problems to the physical chemistry of detergency, and have broken the common and fixed idea about laundery and washing. This laundering method was constructed from the following chief process ; soiled fabrics were coated with a solution of high-polymer or the mixture of high-polymer and surfactant, then dried, and laundered in merely water. There were also many variations, for instance, laundering in a solution of detergent and the omission of the drying. Fundamental conditions for this method, such as the amount of used high-polymer, laundering temperature, laundering time and the effect of surfactant were discussed with the soiled cotton fabrics. The effect of drying and its types was also discussed. Then the effect of this laundering method for hydrophobic fibers was compared with hydrophilic cellulosic fibers. The obtained results of this method have driven off the fixed idea that soiled fabrics and garments must be laundered by the immersion of it in a solution of detergent or organic solvents, and it seems that there might be more variations of laundering method when high-polymers were effectively used.
