<p>The present invention relates to a dry cleaning apparatus and method in which a main portion of a dry cleaner comprises three members of tanks for exclusively receiving at least two kinds of solvents which are soluble in each other, one treating tank and a fractionating device for recovering the two or more kinds of solvents by fractional distillation, or three members of the tanks, the treating tank and exclusive filters for the respective solvents, a common filter or a multi-filter device composed of both the filters, or the above-mentioned four all members; the two or more kinds of solvents are mixed with each other in an optional ratio; and washing and drying are carried out. Further, the present invention relates to a dry cleaning method in which in a dry cleaner of using organic solvents such as perchloroethylene, 1,1,1-trichloroethane, turpentine (oil series) and the like, the already used solvent is replaced with another solvent which is soluble therein and has a lower boiling point, for example, Furon R113 or R11, during washing or immediately before drying in order to thereby shorten a drying period of time. According to the present invention, the most proper washing method can be chosen for the greater part of materials, processings and morphologies of clothes, and troubles of clothes due to washing can be reduced remarkably. Further, the above-mentioned apparatus and method of the present invention can advantageously save occupation space, equipment cost, volume of facilities, maintenance cost and the like. In addition thereto, a drying time can be reduced by half.</p> |
