THE METHOD OF COATING A FABRIC TO PROVIDE A LAMINATED SURFACE FILM THEREON, TO FORM A PRODUCT OF THE CHARACTER OF LEATHER CLOTH AND THE LIKE, COMPRISING PLASTICIZING A RESIN SELECTED FROM THE GROUP CONSISTING OF POLYVINYLCHLORIDE, COPOLYMERS OF VINYLCHLORIDE AND VINYLACETATE, COPOLYMERS OF VINYLCHLORIDE AND VINYLIDENECHLORIDE, BY MIXING THE SAID RESIN, THE REQUIRED QUANTITY OF POWDERED PIGMENTS AND FILLERS AND A SUFFICIENT QUANTITY OF A LIQUID PLASTICIZER FOR SAID RESIN TO FORM A HOMOGENEOUS PASTE CONSISTING OF SAID RESIN, PLASTICIZER, PIGMENTS AND FILLERS AT NORMAL TEMPERATURE, HEATING SAID PASTE TO A TEMPERATURE IN THE RANGE OF 40 TO 120* C. FOR A PERIOD MERELY SUFFICIENT TO OBTAIN A DRY, FRANGIBLE, SOLID MIXTURE OF THE PLASTICIZED RESIN HOMOGENEOUSLY CONTAINING PIGMENTS AND FILLERS, POWDERING SAID DRY PLASTICIZED MIXTURE, APPLYING SAID POWDERED MIXTURE TO THE SURFACE OF A FABRIC, HEATING SAID POWDER COATED FABRIC UNDER EMBOSSING ROLLS HEATED TO A TEMPERATURE IN THE RANGE OF 100 TO 140* C., AND FINALLY HEATING THE EMBOSSED COATED FABRIC TO A TEMPERATURE IN THE RANGE OF 150 TO 190* C. FOR A PERIOD SUFFICIENT TO CONSOLIDATE SAID COATING.
