Abstract:
PROBLEM TO BE SOLVED: To provide a system and a method for dry-cleaning an article by using a siloxane compound. SOLUTION: This system 5 includes a cleaning basket 10 for receiving the article inside and one or more tanks 14 and 16 for storing the siloxane compound. A pump 12 for soaking the article in the cleaning basket by a siloxane solvent, is connected between the tanks and the cleaning basket. A distiller 24 for distilling the dirty siloxane solvent, is included for recovering a pure siloxane solvent. A condenser 26 is connected to the cleaning basket and/or the distiller for recovering condensed steam. A separator 28 is connected to the condenser for transferring the whole moisture in the siloxane solvent received from the condenser. A fan 32 is connected to the cleaning basket for circulating air to the cleaning basket so as to dry and cool the article by the air passing through a heating coil 34. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
A fabric treatment composition including a sizing agent and a silicone solvent is provided. The sizing agent is a hydrogenated rosin ester. The silicone solvent is a volatile silicone solvent. Optionally, co-solvents and dispersing agents may be included. A method of treating a fabric article and the treated fabric article are provided.
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. 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 selected from terpenes, halohydrocarbons, certain glycol ethers, polyols, ethers, esters of glycol ethers, esters of fatty acids and other long chain carboxylic acids, fatty alcohols and other long-chain alcohols, short-chain alcohols, polar aprotic solvents, siloxanes, hydrofluoroethers, dibasic esters, and aliphatic hydrocarbons solvents or similar solvents or mixtures of such solvents and the pressurized fluid solvent is preferably densified carbon dioxide.

Abstract:
A process for fabric article treatment in a single appliance using a substantially aqueous mediumd comprising a first predominant fluid and a substantially non-aqueous medium comprising a second predominant fluid. Specifically, the first and the second predominant fluids are selected to be different in order to deliver more effective results. The first predominant fluid is water and the second predominant fluid is selected from the group consisting of linear or cyclic silicones, hydrocarbons, glycol ethers, and mixtures thereof.
