AN ARTICLE (10) HAVING (A) LAYER OF FABRIC HAVING A FIRST SURFACE (20) AND A SECOND SURFACE (21) MADE OF POLYTETRAFLUOROETHYLENE FIBERS; AND (B) A FIRST COMPOSITE (14) COMPRISING (i) A POROUS PTFE FILM HAVING INTERCONNECTED PASSAGES AND PATHWAYS AND (ii) A FLUOROPOLYMER ADHESIVE, WHEREIN SAID FLUOROPOLYMER ADHESIVE IS AT LEASR PARTIALLY CONTAINED IN SAID PASSAGES AND PATHWAYS OF SAID PTFE FILM, SAID FIRST COMPOSITE (14) DISPOSED ADJACENT TO SAID FIRST SURFACE (20) OF SAID FABRIC, WHEREIN THE ARTICLE (10) PASSES A NEWARK FLEX TEST AFTER 10,000 CYCLES. IN ANOTHER EMBODIMENT, THE INVENTION INCLUDES A SECOND COMPOSITE COMPRISING (i) A POROUS PTFE FILM HAVING INTERCONNECTED PASSAGES AND PATHWAYS AND (ii) A FLUOROPOLYMER ADHESIVE, WHEREIN SAID FLUOROPOLYMER ADHESIVE IS AT LEAST PARTIALLY CONTAINED IN SAID PASSAGES AND PATHWAYS OF SAID PTFE FILM, SAID SECOND COMPOSITE DISPOSED ADJACENT TO SAID SECOND SURFACE (21) OF SAID FABRIC. THE ARTICLE (10) OF THE PRESENT INVENTION IS PREFERABLY WATERPROOF, FIRE RETARDANT, AND FLEXIBLE. IT IS ALSO PREFERABLY AN ARCHITECTURAL FABRIC FOR RETRACTABLE, TEMPORARY, OR PERMANENT STRUCTURES AND IS ADAPTED TO BE JOINED TO ITSELF BY HEAT WELDING.
