ABSTRACT:
There are disclosed a dry cleaning method and apparatus using organic solvents in which two types of solvents melted to each other, one of which is a solvent (for example, perchloroethylene or 1.1.1 trichloroethane) having large washing power and the other of which is a solvent (for example, fleon R113 or terpene) having high safety for clothes can be simultaneously possessed and mixed to a predetermined mixture ratio in the range in which the respective characteristics of both the solvents do not interfere with each other by a fractionating device of the solvents, whereby almost all materials for clothes can be cleaned.
With the structure, a single dry cleaner can clean almost all material for clothes and can increase the generality greatly as compared with the prior art cleaner.
