Abstract:
L'invention concerne un procédé de nettoyage de vêtements contaminés. Conformément à l'invention, le nettoyage est réalisé selon un processus de nettoyage à sec, ledit processus incluant au moins deux étapes de traitement, dont une étape de traitement primaire par passage des vêtements dans un premier bain constitué par une première émulsion comportant un solvant de nettoyage additionné d'une faible quantité d'eau et un additif lessiviel décontaminant, suivie d'une étape de traitement secondaire par passage des vêtements traités dans un deuxième bain constitué par une deuxième émulsion, formée de constituants différents de ceux de la première émulsion, et comportant le même solvant de nettoyage additionné d'une faible quantité d'eau, ainsi qu'un additif lessiviel antistatique et antiseptique et au moins un agent détachant, l'eau représentant dans chaque bain un pourcentage en volume par rapport à la quantité de solvant de nettoyage qui est compris entre 0,1% et 10%.
Abstract:
a method for drying lipophilic fluid-containing fabric articles comprises one or more of the following steps: (a) adding a high vapor pressure co-solvent to the lipophilic fluid prior to contacting the fabric articles with the lipophilic fluid, (b) pre-heating the lipophilic fluid prior to contact with the fabric articles, (C) pre-heating
Abstract:
The invention regards a system and method for dry cleaning articles, the system comprising a cleaning basket (10) for receiving the articles, a tank (14, 16) containing a solvent, a pump (12) coupled between the tank (14, 16) and the cleaning basket (10) for introducing solvent into the cleaning basket, either a still for distilling the solvent or a Kleen Rite® cartridge filter system, a fan (32) coupled to the cleaning basket (10) for circulating air past a heater (34) and into the cleaning basket (10) for drying the articles, a condenser (36) coupled to the cleaning basket (10) and producing a condensed mixture of water and solvent; and a separator (28) coupled to the condenser (36) for separating water in the condensed mixture from solvent in the condensed mixture. According to the invention the solvent is a siloxane solvent, the separator (28) separates water in the condensed mixture from siloxane solvent in the condensed mixture via gravity, and at least one coalescent medium (56, 64) is provided that is coupled to or located inside the separator (28).
Abstract:
The invention can provide a detergent composition for dry cleaning which comprises a nonionic surfactant as the component (a), a cyclic polysiloxane as the component (b) and a polyether modified silicone having a HLB value of at most 6 as the component (c), wherein the content of the component (a) is 5 to 70% by weight based on the total weight of the components (a), (b) and (c), the content of the total of the components (b) and (c) is 30 to 95% by weight based on the same, and the ratio by weight of the component (b) to the component (c) {b / c} is 1 / 10 to 20 / 1 and a detergent liquid for dry cleaning using the above detergent composition. The detergent composition and detergent liquid are excellent in detergency, capability of preventing recontamination and solubilizing power in water, which is less prone to cause annular stain on clothes even when a pretreatment agent is used, which imparts favorable flexibility and conformability to an object to be cleaned and which has favorable stability with the lapse of time.
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 (112, 122) 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, pressurzed fluid solvent is pumped from the drum (112, 122). 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 system and method are provided for separating water from solvent during dry cleaning. Included is an inlet (52) capable of receiving a mixture of dry cleaning fluid and water from a basket of a dry cleaning apparatus. The dry cleaning fluid includes a siloxane composition. Also provided is a flow controller (60) for urging flow of the mixture received from the outlet. Coupled to the flow controller (60) is a coalescent media (64) that receives the mixture urged by the flow controller (60). A chamber (68) is coupled to the coalescent media (64) for receiving the mixture from the coalescent media (64) to separate the water and the dry cleaning fluid. Also coupled to the chamber (68) is an outlet (69) to remove the dry cleaning fluid from the chamber (68) in the absence of water.
