Abstract: A cleaning system that utilizes an organic cleaning solvent and pressurized fluid solvent is disclosed. The system has no conventional evaporative hot air drying cycle. Instead, the system utilizes the solubility of the organic solvent in pressurized fluid solvent as well as the physical properties of pressurized fluid solvent. After an organic solvent cleaning cycle, the solvent is extracted from the textiles at high speed in a rotating drum in the same way conventional solvents are extracted from textiles in conventional evaporative hot air dry cleaning machines. Instead of proceeding to a conventional drying cycle, the extracted textiles are then immersed in pressurized fluid solvent to extract the residual organic solvent from the textiles. This is possible because the organic solvent is soluble in pressurized fluid solvent. After the textiles are immersed in pressurized fluid solvent, pressurized fluid solvent is pumped from the drum.

Abstract: Method includes the steps of (1) treating the textile with a predetermined amount of a non-durable sacrificial repellent material before putting the textile in service; (2) cleaning the textile with a mixture of a non-polar solvent and at least one cleaning additive to remove non-polar solvent soluble, insoluble and resistant contaminants from the textile; (3) washing the textile with a mixture of a polar solvent and at least one washing additive to remove polar solvent soluble contaminants from the textile; and (4) maintaining a predetermined amount of a non-durable sacrificial repellent material on the textile. The non-polar solvent may be perchloroethylene or the like, while the cleaning additive is a mixture of a dialkyl ketone, a carboxylic ester and a glycol ether. A second cleaning additive may be used to enhance contaminant removal. The polar solvent used is water, while the washing additive is a blend of surfactants.
