Abstract:
The invention concerns a composition for thy-cleaning textile articles, characterised in that it is anhydrous and in that it comprises, as an active cleaning agent: dipropylene glycol monomethyl ether, an amphiphilic solvent A chosen from the group consisting of dipropylene glycol mono-n-propyl ether, dipropylene glycol mono-n-butyl ether, dipropylene glycol mono-tert-butyl ether or the mixtures thereof, and at least one dibasic ester B having a KB index higher than 30 and represented by the following general formula (I): R—O—C(═O)—(CH2)n-C(═O)—O—R′ (I) in which n is a whole number between 1 and 9; R and R′ are identical or different, each separately representing an alkyl group having 1 to 6 carbon atoms, or an alkenyl group having 2 to 6 carbon atoms.
Abstract:
A dry cleaning system arranged for washing articles employing a cleaning solution. The dry cleaning system includes a wash tank (2) for washing an article to be washed with a cleaning solution. The wash tank (2) is arranged for washing the article at an increased pressure compared to atmospheric pressure. The dry cleaning system includes a fluid displacement device (1), such as a pump, connected to the wash tank (2) and is arranged for transferring the cleaning solution through the dry cleaning system in a first operational mode. The fluid displacement device is arranged to reduce the pressure in the wash tank towards atmospheric pressure in a second operational mode.
Abstract:
Dry cleaning and fabric-treatment compositions, methods and articles incorporating the same that are suitable for use in drying machines, such as hot air drying machines found in households, apartments, and laundromats, which are normally adapted to dry wet garments and the like from a washing machine In some embodiments, the composition includes at least one organic solvent, with the at least one organic solvent forming the greatest weight percentage of the active components in the composition. In some embodiments, the composition also may include water and/or at least one surfactant, emulsifier, perfume, and/or application-specific composition. In some embodiments, the article includes a dispenser from which the composition is selectively dispensed onto a dry garment or other object to be cleaned. In some embodiments, the dispenser includes an internal chamber containing the composition, and the composition is dispensed onto objects prior to placing the objects in a drying machine
Abstract:
Textiles are cleaned by first treating soiled areas of the textile with at least one pre-spotter material which is an alcohol polyoxyalkylene derivative or a benzoate ester. The textiles are subsequently dry cleaned in a medium based on liquid C02, typically also including a cleaning additive, particularly a multi-ester. The textile may also be treated with a fabric conditioner, particularly a fatty alcohol or fatty acid branched polyalkoxylate which may be included in the dry cleaning medium or in a subsequent rinse cycle.
Abstract:
A cleaning method and system that utilize an organic cleaning solvent and pressurized fluid solvent is disclosed. The method and system have no conventional evaporative hot air drying cycle. Instead, the method and system utilize 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. Finally, the drum is de-pressurized to atmospheric pressure to evaporate any remaining pressurized fluid solvent, yielding clean, solvent free textiles. The organic solvent is preferably dipropylene glycol n-butyl ether, tripropylene glycol n-butyl ether or tripropylene glycol methyl ether, a mixture thereof, or a similar solvent and the pressurized fluid solvent is preferably densified carbon dioxide.
Abstract:
A fabric cleaning system, especially a system for use in the consumer's home, utilizing down the drain detergent composition for a non-aqueous, lipophilic fluid based washing process and automatic laundry machines useful for this process.
Abstract:
A composition containing a silicone-containing polymer for cleaning fabric articles, especially articles of clothing, linen and drapery, with lipophilic fluid provides improved cleaning of soils while providing excellent garment care, especially for articles sensitive to water.
Abstract:
Compositions and methods for removing and/or reducing incidental soils from fabric articles, especially articles of clothing, linen and drapery, wherein the compositions provide improved cleaning of incidental soils, either with or without a subsequent wash process or other entire fabric care process are provided. The compositions and methods are safe for use on a wide range of fabric articles, even in the home.
