    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: The invention discloses a novel method for dry cleaning of a fabric material characterized by the use of a unique dry cleaning solvent which is a tris(trimethylsiloxy) silane compound represented by the general formula of RSi(—O—SiMe3)3, in which Me is a methyl group and R is a monovalent hydrocarbon group of 1 to 6 carbon atoms or, preferably, a methyl group, or a mixture thereof with a petroleum-based hydrocarbon solvent in a limited proportion. In addition to the excellent effect of dry cleaning equivalent to that of conventional dry cleaning solvents and little unpleasant smell remaining on the fabric material, the solvent used in the inventive method is little liable for the problems of environmental pollution against public and workers' health and the problem of ozone layer destruction in the aerosphere due to emission of vapors of halogenated hydrocarbon solvents can be solved by the inventive method.

    Abstract: The process of the present invention is directed to a dry cleaning process, comprising the use of volatile cyclic, linear or branched siloxanes in the vapor phase for the cleaning of soiled or stained fabrics. The linear or branched siloxanes have the formula: M2+y+2zDxTyQz wherein M is R13SiO1/2; D is R2R3SiO2/2; T is R4SiO3/2; and Q is SiO4/2 R1, R2, R3 and R4 are each independently a monovalent hydrocarbon radical having from one to forty carbon atoms; and x and y are each integers, wherein 0≦x≦10 and 0≦y≦10 and 0≦z≦10. While the cyclic siloxanes have the formula: wherein R5, R6, R7 and R8 are each independently a monovalent hydrocarbon group having from one to forty carbon atoms; and a and b are each integers wherein 0≦a≦10 and 0≦b≦10, provided that 3≦(a+b)≦10.
