Abstract
Described herein is a solution for use in cleaning articles comprising, a dry cleaning agent, wherein the dry cleaning agent comprises a siloxane solvent, a hydrocarbon solvent or a combination thereof, and an enhancer, which raises a KBV value of the solution. The enhancer can be soluble in the dry cleaning agent and water. Also described herein is a dry cleaning system that utilizes the solution, as well as a purification system for purifying the solution.
Claims22
A solution for use in cleaning articles comprising:
- a dry cleaning agent, wherein the dry cleaning agent comprises a siloxane solvent, a hydrocarbon solvent or a combination thereof;
- and
- an enhancer.
A system adapted for dry cleaning articles using a solution which includes a dry cleaning agent comprising a siloxane solvent, a hydrocarbon solvent, or a combination thereof, and an enhancer which is miscible in water and in the dry cleaning agent, the system comprising:
- a container for the articles;
- a vessel for the solution;
- a filter for separating the solution from impurities during and after cleaning;
- and
- a pump coupled to the container, the pump adapted to deliver a quantity of the solution from the container to the filter.
A purification system for the purification of a used dry cleaning solution, the solution including (i) water;
- (ii) a first cleaning component comprising a siloxane solvent, a hydrocarbon solvent, or a mixture thereof;
- (iii) a second cleaning component which is an enhancer which is soluble into both water and the first cleaning component, the purification system comprising:
- a distilling system adapted to remove water from the used dry cleaning solution at ambient atmospheric conditions and divert the water for one of reuse, storage, and disposal;
- and
- a vacuum administrating system used in distilling the first and second cleaning components from the used dry cleaning solution in a vacuum and diverting the first and second cleaning components for one of reuse and storage.
