Abstract:
1,2-Octanediol is used to clean soiled fabrics. Thus, cleaning compositions comprising 1,2-octanediol, preferably in combination with solvents, are impregnated into carrier sheets. The sheets are tumbled with soiled fabrics inside of a plastic bag. The resulting home dry cleaning process leaves the fabrics clean and refreshed.
Abstract:
Stable azeotrope-like compositions consisting essentially of dichloropentafluoropropane and a hydrocarbon containing six carbon atoms which are useful in a variety of industrial cleaning applications including cold cleaning and defluxing of printed circuit boards.
Abstract:
Disclosed are formulations for producing chemical solvent admixtures that can be employed to clean a surface for further work; and that can be applied to cloths for the cleaning operation yet alleviate problems with solvent evaporation into the atmosphere to cause many legal and environmental problems, and a method of storing and disposing of cloths soaked with the formulation that alleviates current problems.
Abstract:
The present invention is directed to a novel single, unit-dose drycleaning article in which at least a portion thereof dissolves in a drycleaning solvent during the drycleaning cycle for releasing a premeasured amount of a drycleaning additive contained within the article. The single, unit-dose drycleaning article is generally in the form of a sealed tub formed of a polystyrene. The unit-dose tub preferably dissolves within about one minute after being in contact with the drycleaning solvent to ensure release and adequate mixing of the drycleaning additive with the drycleaning solvent to effect maximum drycleaning results. In an alternative form, the single, unit-dose drycleaning article may be partially formed with a material that dissolves in a drycleaning solvent. In that form, it is preferred to locate the single, unit-dose drycleaning article in a sealable enclosure, such as a sealable bag, net or basket, which is formed of a material that is drycleaning solvent-insoluble, drycleaning solvent-permeable, such as a polyethylene, polypropylene, nylon, polyester, cotton, metal, etc., so that the remaining or non-dissolved portion of the single, unit-dose drycleaning article can be retrieved at the end of the drycleaning cycle.
Abstract:
Process for cleaning clothes at home with the aid of solvent, byA. treating the article of clothing with a cleaning agent comprising at least one organic solvent, and thenB. laying the article of clothing flat on an absorbent sheet, andC. laying the article of clothing+absorbent sheet flat on the interior circular surface of the drum of a washing machine in order to spin it.Operation A can be carried out in two successive stages using a stain-removing agent and a rinsing agent.
Abstract:
The specification discloses a method and apparatus for packaging and dispensing stain removing agents in small, individualized capsules. The stain removing agents are preferably in paste form. The individual capsules are readily deformable and are stored in individual troughs in a receiving plate which, in turn, is covered by a covering sheet.
Abstract:
Synthetic textiles are both degreased and desized by passing the textiles through a bath of an anhydrous solvent containing a dissolved alkaline agent. The textile is then preferably rinsed in a compatible solvent.
