Patent number: 6755871Abstract: 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.Type: GrantFiled: April 18, 2001Date of Patent: June 29, 2004Assignee: R.R.

Patent number: 6148644Abstract: A system for dry cleaning soils from fabrics comprising densified carbon dioxide and a surfactant in the densified CO.sub.2. The densified carbon dioxide is in a temperature range of about -78.5.degree. C. to about 100.degree. C. and a pressure range of about 14.7 to about 10,000 psi. At least 0.1% by volume of a modifier is preferably present. The surfactant has a polysiloxane, a branched polyalkylene oxide or a halocarbon group which is a functional CO.sub.2 -philic moiety connected to a CO.sub.2 -phobic functional moiety. The surfactant either exhibits an HLB of less than 15 or has a ratio of siloxyl to substituted siloxyl groups of greater than 0.5:1.Type: GrantFiled: May 19, 1998Date of Patent: November 21, 2000Assignee: Lever Brothers Company, division of Conopco, Inc.Inventors: Sharon Harriott Jureller, Judith Lynne Kerschner, Dennis Stephen Murphy
