Abstract
Water or organic solvent soluble impurities are removed from textile materials at a treatment zone by applying to the material a first liquid capable of dissolving the impurities, following which a second liquid immiscible with the first liquid is applied to the material to expel the first liquid and the dissolved impurities. The two liquids are then separated and the material is removed from the treatment zone and dried without further contact with the first liquid.
