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.
Abstract:
Fabric article treatment in a domestic appliance having at least one detergency step, products therefor, and kits which combine treatment products for more effective results. The treatment products are suitable for washing or refreshing fabrics and are used in the presence of a lipophilic cleaning fluid.
Abstract:
A dry cleaning system and method comprises dry cleaning machinery used in conjunction with a cyclic siloxane solvent. In order to enhance the cleaning capabilities of the cyclic-siloxane-based solvent, such solvent is modified with a chemical that is selected from the group of chemicals including 2-ethylhexyl acetate, esters, alchohols, and ethers.
Abstract:
A dry cleaning system and method comprises specially designed or modified machinery used in conjunction with a cyclic siloxane solvent. In a preferred embodiment, the method comprises the steps of loading articles into a cleaning basket; agitating the articles and the siloxane composition in which they are immersed; removing most of the siloxane composition; centrifuging the articles; subjecting the articles to a partial vacuum pressure and elevated temperature; and removing the articles from the basket after cooling the articles and returning the pressure to ambient.
Abstract:
The present invention relates to a process for cleaning goods comprising the following steps: a) placing the goods to be cleaned in a pressure-resistant cleaning vessel, b) introducing a cleaning solvent into the cleaning vessel, c) removing the residues carrying solvent from the container, d) separating the residues from the solvent, characterised in that, step b and step c are carried out at least twice, therefore leading at least to a first and second cleaning bath, using a halogenated and/or hydrocarbons containing solvent in one cleaning bath, and using a pressurised fluid containing solvent in another cleaning bath. Furthermore, the present invention relates to a process of the kind mentioned above, characterised in that, step b and step c are carried out at least once, therefore leading at least to one cleaning bath, using a halogenated and/or hydrocarbons containing solvent in combination with a pressurised fluid containing solvent in at least one cleaning bath.
Abstract:
A fabric article treatment appliance capable of washing and drying fabric articles, moreover, the appliances is capable of providing and using a first and a second predominant fluid in the washing step, wherein the first and the second predominant fluids are different.
Abstract:
A detergent composition for dry cleaning which comprises (a) a nonionic surfactant, (b) a cyclic polysiloxane and (c) a polyether−modified silicone having a HLB value of 6 or less, in amounts satisfying that, relative to the total amount of the components (a), (b) and (c), the component (a) accounts for 5 to 70 wt %, the sum of the weights of components (b) and (c) is 30 to 95 wt %, and the weight ratio of the components (b) to (c), (b)/(c), is 1/10 to 20/1; and a cleaning solution for dry cleaning using the detergent composition. The detergent composition is excellent in detergency, the capability of preventing re−soiling, and the capability of solubilizing water, is less susceptible to the occurrence of a ring strain in a cloth when a pretreatment agent is used, can impart good softness to a material to be cleaned, and exhibits good stability for a long time.

Abstract:
A system and method are provided for dry cleaning articles utilizing a siloxane solvent. The system (5) includes a cleaning basket (10) for receiving articles therein and one or more tanks (14, 16) for containing a siloxane solvent. Coupled between the tank and the cleaning basket is a pump (12) for immersing the articles in the cleaning basket with the siloxane solvent. Also included is a still (24) for distilling the dirty siloxane solvent to recover the pure siloxane solvent. A condenser (26) is coupled to the cleaning basket and/or the still for recovering condensed vapors. For decanting any water in the siloxane solvent received from the condenser, a separator (28) is coupled to the condenser. A fan (32) is coupled to the cleaning basket for circulating air past the condenser, then the heater coils (34) and into the cleaning basket for drying and cooling the articles.
