Abstract
An improved method of laundering clothes and textiles comprises: providing a washing machine having a tub furnished with a fixed outer shell 11 and an inner cylinder 12 that is provided within the outer shell 11, that is rotatably supported on a horizontal rotating shaft 13 and that has a plurality of orifices in the outer peripheral wall through which a washing solution can pass; putting the clothes and textiles into the inner cylinder 12; charging the outer shell 11 with a washing solution Q having a polyelectrolyte containing detergent dissolved therein; and laundering the clothes and textiles with ozone gas from an ozonizer 21 being introduced from an ozone gas supply port 24a directly into the washing solution Q at a temperature of from about 40.degree. C. to less than 50.degree. C., preferably from about 40.degree. C. to about 45.degree. C. between the outer shell 11 and inner cylinder 12. The method has such a great laundering power that severe soiling of the collar and yellowing can be removed in a regular washing cycle without employing any preliminary or post treatments. In addition, the method can be implemented with existing commercial washing machines with ozone being readily introduced into washing solutions even if no special means is employed to mix them with ozone gas.
