Abstract: A PROCESS FOR CLEANING SOILED FABRICS WHICH UTILIZES AN APPARENTLY DRY CLEANING MEDIUM COMPRISING A FINELY PARTICULATE CARRIER ADSORBED WITH A CLEANING LIQUID. THE SOILED FABRIC IS PLACED INTO A PLENUM CONTAINING THE CLEANING MEDIUM AND THE MEDIUM IS FLUIDIZED BY DIRECTING AN AIR STREAM THROUGH THE PLENUM. DIFFERENTIAL MOTION IS APPLIED BY TRANSDUCER MEANS TO THE PARTICULATES OF THE MEDIUM WHILE THE FABRIC IS IN THE PLENUM. THE FOREIGN MATERIAL CARRIED BY THE FABRIC IS TRANSFERRED TO THE CLEANING MEDIUM DUE TO THE SOURING ACTION OF THE MEDIUM. THE APPARATUS FOR THE PROCESS COMPRISES AN ENCLOSURE HAVING WITHIN IT THE MENTIONED PLENUM, MEANS FOR RETAINING THE SOILED FABRIC WITHIN THE PLENUM AND MEANS FOR DIRECTING AN AIR STREAM THROUGH THE CLEANING MEDIUM TO FLUIDIZE THE CLEANING MEDIUM AND THEREAFTER T RECIRCULATE THE AIR STREAM. TRANSDUCER MEANS APPLIES A DIFFERENTIAL MOTION TO THE PARTICULATES TO AID IN THE CLEANING ACTION.
