ABSTRACT:
A load of garments or other textile material to be washed is presoaked in organic solvent, e.g. in a rotating drum, and is then immersed within the same vessel in a water bath while still permeated by a substantial quantity of solvent. During this immersion, the vessel is gradually heated to the boiling point of the solvent, or of the azeotropic water/solvent mixture, which is below the boiling point of water so that only a part of the wash liquor is vaporized. The evaporation can be accelerated by placing the vessel under a partial vacuum. The evaporation rate of the solvent is measured and the washing cycle is halted as soon as that rate drops to zero or below a predetermined limit, with subsequent drying of the load by, for example, centrifugation.
