Aqueous Component Patents (Class 510/291)
  • Patent number: 9138660
    Abstract: A method for efficiently reducing water content of an object to be treated that contains water without requiring a high-temperature environment such as one exceeding the boiling point of water, and a method for efficiently extracting an oil-soluble substance from an object to be treated that contains water and the oil-soluble substance. A method for reducing water content of an object to be treated and/or extracting an oil-soluble substance in the object to be treated into oil is performed by mixing the object to be treated containing water or water and the oil-soluble substance with an oil at a temperature that is lower than the boiling point of water, at which temperature the oil is a liquid.

  • Patent number: 8470053
    Abstract: The present invention relates to compositions and methods for wet-cleaning, in professional or household washing machine equipment, and subsequent drying in a tumbler dryer, of garments made of protein-fibers (animal based fibers) such as wool, cashmere, silk and other sensitive fibers. Using water and certain additives instead of organic solvents, these compositions enable the cleaning, including oil stains removal, and subsequent drying without incurring dimensional changes, shrinkage, surface damages, dye or color loss of dry clean only labeled garments or other delicate garments labeled for special care.

  • Patent number: 6755871
    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: 6200352
    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.

  • Patent number: 6190420
    Abstract: The invention is directed to a dry-cleaning article suitable for use in the home. The article is characterized by a sheet that is permeated with a composition including 51-98% by weight of organic solvent such as paraffins, olefins, acetylenes or mixtures thereof, 1-35% by weight of water, and 1-14% by weight of emulsifier to allow the water to be uniformly mixed into the solvent. The composition can also include 1-5% by weight of perfume for scenting clothing, and 1-5% by weight of nonionic and/or anionic surfactant to provide additional stain removal capability of the composition. The invented composition is thus organic-solvent-based and is particularly effective to remove body or cosmetic oil stains from garments. The invention is also directed to the composition and methods for using the sheet in a drying machine.

  • Patent number: 6184193
    Abstract: A shrinkage prevention agent for water washing of clothing that would conventionally have been dry cleaned. The shrinkage prevention agent is compromised of a steam or vacuum dry-distilled liquid of two or more plants selected from sagebrush, beefsteak plant, tea, plantaginales, aloe, chrysanthemum, pine, cedar, cypress. The shrinkage prevention agent is used in a wet cleaning system that includes water washing.

  • Patent number: 6148644
    Abstract: 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.
