Abstract
The present invention contemplates a rinse process which can be used with any wash cycle, but which has particular utility following a wash cycle have a highly concentrated detergent solution. The method of rinsing fabric provided by the present invention is useful in a washer having a wash chamber rotatable about a horizontal axis. The steps undertaken in the method begin with loading fabric to be washed into the wash chamber of the washer. The fabric is then washed in a detergent solution while rotating the wash chamber about its horizontal axis for a first period of time. Next the detergent solution is drained from the wash chamber. The fabric is then rinsed by adding water to the wash chamber while spinning the wash chamber at a speed to effect less than a one gravity centrifugal force on the fabric such that the fabric will tumble within the wash chamber as it spins. Finally, the wash chamber is drained of the rinse water.
