  • Patent number: 6558432
    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.

  • Patent number: 6461387
    Abstract: A system for dry cleaning soils from fabrics comprising densified carbon dioxide and a surfactant in the densified CO2. The densified carbon dioxide is in a temperature range of about −78.5° C. to about 100° 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 CO2-philic moiety connected to a CO2-phobic functional moiety. The surfantant either exhibits an HLB of less than 15 or has a ratio of siloxyl to substituted siloxyl groups of greater than 0.5:1.

  • Patent number: 6297206
    Abstract: A method for dry-cleaning garments or fabrics in carbon dioxide comprises contacting a garment or fabric article to be cleaned with a liquid dry cleaning composition for a time sufficient to clean the article, said liquid dry-cleaning composition comprising a mixture of carbon dioxide, water, a first surfactant, and a second surfactant, and then separating the article from the liquid dry cleaning composition. The first surfactant comprises a CO2-philic group covalently joined to a hydrophilic group; and the second surfactant comprising a CO2-philic group covalently joined to a lipophilic group. In the alternative, a single surfactant containing all three of a CO2-philic group, a lipophilic group, and a hydrophilic group covalently joined to one another may also be employed. Systems useful for carrying out the foregoing are also disclosed.

  • Patent number: 6280481
    Abstract: A method for dry-cleaning articles such as fabrics and clothing in carbon dioxide while concurrently applying a sizing agent to the articles comprises contacting an article to be cleaned with a liquid dry cleaning composition for a time sufficient to clean the fabric. The liquid dry-cleaning composition comprises a mixture of carbon dioxide, a surfactant, a sizing agent. An organic co-solvent is preferably included. After the contacting step, the article is separated from the liquid dry cleaning composition. The method is preferably carried out at ambient temperature. Preferred sizing agents are low molecular weight hydrocarbon resins. The surfactant is preferably one that does not contain a CO2-philic group. The organic co-solvent is preferably an alkane and has a flash point above 140° F.
