Abstract: A method for dry-cleaning articles such as fabrics and clothing in carbon dioxide 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, and an organic co-solvent. After the contacting step, the article is separated from the liquid dry cleaning composition. The method is preferably carried out at ambient temperature. 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.

Abstract: A method of treating a substrate comprises contacting a surface of said substrate, with a pressurized fluid comprising carbon dioxide and a surface treatment component, the surface treatment component being entrained in the pressurized fluid and contacting the surface so that the surface treatment component lowers the surface tension of the surface of the substrate and treats the substrate. The contacting step is preferably carried out by immersion, the fluid is preferably a liquid or supercritical fluid, the substrate is preferably a metal or fabric substrate, and the surface treatment component is preferably a fluoroacrylate polymer.

Abstract: A system for the controlled addition of detergent formulations and the like to a carbon dioxide cleaning apparatus comprises: (a) a high pressure wash vessel; (b) an auxiliary vessel; (c) a drain line connecting the auxiliary vessel to the wash vessel; (d) optionally but preferably, a separate vent line connecting the auxiliary vessel to the wash vessel; (e) a detergent reservoir; and (f) a detergent supply line connecting the detergent reservoir to the auxiliary vessel. An advantage of this apparatus is that, because the detergent formulation can be pumped into the auxiliary vessel in a predetermined aliquot or amount, which predetermined aliquot or amount can then be transferred into the wash vessel where it combines with the liquid carbon dioxide cleaning solution, the detergent formulation can be added to the cleaning solution in a more controlled or accurate manner. An alternate embodiment adapted for the addition of aqueous detergent formulations and the like to a carbon dioxide dry cleaning system under turbulent conditions comprises: (a) a high pressure wash vessel; (b) a filter; (c) a carbon dioxide cleaning solution drain line interconnecting the wash vessel to the filter; (d) a carbon dioxide cleaning solution supply line connecting the filter to the wash vessel; (e) a first high pressure pump (i.e., a pump that is capable of pumping liquid solutions comprising liquid carbon dioxide) operably connected to the drain line; (f) a detergent formulation reservoir; (g) a detergent formulation supply line connecting the reservoir to the carbon dioxide cleaning solution supply line; and (h) a second high pressure pump operably connected to the detergent formulation supply line for transferring detergent formulation from the detergent formulation reservoir into the carbon dioxide cleaning solution under turbulent conditions.

Abstract: A wash tank (10) adapted for use with a carbon dioxide cleaning medium has a body member (20) having a front opening (22) formed therein, the body member having side walls (23) and a back wall (24) opposite the front opening. The side walls terminate in a front body member edge portion (25) that defines the front opening. A substantially cylindrical basket (30) is disposed within the body member for rotation about a generally horizontal axis. The basket side wall terminates in a front basket edge portion defining the basket front opening. The said basket edge portion (32) is spaced forward from the body member edge portion (25) when the basket is positioned in the body member, serving to prevent loose garments or materials placed within the basket from becoming caught in the seal and interfering with seal integrity. A drive mechanism (50) is included to rotate the basket about the axis. A door (21) is hingeably (26) connected to the body member, with the door having a front wall and side walls, and with the side walls terminating in an inner edge portion (29) configured to abut said body member edge portion. The door inner edge portion (29) and the body member edge portion (25) comprise a seal for sealing the door and body member to form an enclosed pressure vessel. A plug (65) is connected to the door, the plug having a surface portion configured to abut the basket front opening when the door is closed. Methods and systems employing the tank are also disclosed.

CPC classification number: D06L1/02
Abstract: The present invention provides a dry cleaning process that facilitates distribution of detergent and solvent and (optionally) facilitates recovery of cleaning by-products in conjunction with the cleaning of articles at a dry cleaning facility. The proces comprises the steps of: (a) receiving from a source a dry cleaning solvent at the dry cleaning facility, the solvent consisting essentially of carbon dioxide; (b) receiving a concentrated detergent formulation (preferably a liquid formulation) at the cleaning facility; (c) accepting from customers soiled articles to be cleaned at the cleaning facility; (d) mixing the dry cleaning solvent and the concentrated detergent formulation to provide a dry cleaning formulation comprised of from 30 or 40 to 99 percent by weight of carbon dioxide solvent; (e) cleaning the articles in a cleaning apparatus to produce cleaned articles; (f) at least periodically distilling the dry cleaning formulation to produce a still residue comprising surfactant and soil; and then (g) returning the cleaned articles to the customers. Optionally but preferably, the process further comprises the step of: (h) returning the still residue to a waste collector or reprocessor for suitable disposal.
