Abstract:
An process for treating or cleaning fabric articles, especially articles of clothing, linen and drapery, wherein the method comprises contacting the fabric articles to be cleaned or treated with a cleaning fluid comprising a lipophilic fluid and removing from the fabric articles a portion of the cleaning fluid.
Abstract:
The present invention relates to a process for treating a lipophilic fluid contained in an emulsion of water and lipophilic fluid. The process includes the steps of pretreating the emulsion, removing lipophilic fluid from the emulsion, and purifying the lipophilic fluid to remove at least a portion of the impurities collected during the use of the emulsion. Method options are provided for each of the aforementioned steps.
Abstract:
Compositions for treating fabric articles, especially articles of clothing, linens and drapery, wherein the compositions provide improved cleaning of soils from and/or care of and/or treatment of fabric articles, especially while providing superior garment care for articles sensitive to water as compared to conventional fabric article treating compositions, are provided.
Abstract:
Fabric article treatment in a domestic appliance using at least a first and a second predominant fluids. Specifically, the first and the second predominat fluids are selected to be different in order to deliver more effective results. The first and the second predominant fluids are independently selected from the group consisting of water, linear or cyclic silicones, hydrocarbons, glycol ethers, and mixtures thereof.
Abstract:
A process for purifying dry cleaning solvents from a mixture containing used dry cleaning solvents and contaminants, such as laundry soils, fabric treating agents.
Abstract:
A washing method for removing oily soil from an object stained therewith by contacting the object with a non-flammable washing agent composition comprising 0.001 to 30 parts of a fluorine-free absorbent which can absorb and capture oily soil and not less than 70 parts of perfluorocarbon liquid to remove the soil from the object.
Abstract:
A method for removing sulfur impurities from petroleum liquids comprising adding to the petroleum liquid a fatty acid, naphthalene, water and a cellulosic container containing a cellulosic material coated with a chromate compound.
Abstract:
Peracids and a water-soluble inorganic polyphosphate salt are used in the treatment of dirty dry cleaning baths to permit longer operation between distillation.
Abstract:
RESIDUAL MOISTURE AND SULFUR AND OTHER RESIDUAL REDUCING AGENT IMPURITIES CONTAINED IN DRYCLEANING SOLVENTS ARE REMOVED BY ADDING TO THE SOLVENTS AN UNSUBSTITUTED AROMATIC HYDROCARBON OR A HALOGEN OR ALKYL SUBSTITUTED AROMATIC HYDROCARBON DRIED CELLULOSIC MATERIAL ON WHICH HAS BEEN PRECIPITATED A FINE DEPOSIT OF LEAD DICHROMATE. THE SAME MATERIALS MAY ALSO BE ADDED TO PETROLEUM PRODUCTS IN ORDER TO REMOVE SULFUR IMPURITIES THEREFROM.
Abstract:
A method of dry cleaning of goods in which the majority of the solvent present in the goods at the conclusion of the actual cleaning is recovered by circulating air, by means of a fan, through the goods in a dry cleaning drum and through a watercooled condenser and a heating element, and then a small remaining amount of solvent is removed from the goods by a deodorizing operation, in which air is passed in a closed circuit through the goods in the dry cleaning drum and over a refrigerated surface on which the solvent is condensed.
