A METHOD OF MAKING A COATED FABRIC COMPRISING MELTING POLYETHYLENE PLASTIC MATERIAL, EXTRUDING IT AT A TEMPERATURE OF FROM 425* TO 475*F. ONTO ONE SIDE ONLY OF A CONTINUOUSLY RUNNING LENGTH OF CLOSELY WOVEN FABRIC MAINTAINED UNDER TENSION, THE SAID FABRIC BEING MADE OF DIMETHYL TEREPHTHALATE-ETHYLENE GLYCOL CONDENSATION PRODUCT AND HAVING NUMEROUS FREE FILAMENT ENDS AND THREAD LOOPS EXTENDING FROM ITS SURFACE, THE SAID ENDS AND LOOPS BEING WETTED BY THE POLYETHYLENE, COOLING THE SIDE OF THE FABRIC OPPOSITE TO THE AFORESAID SIDE ONTO WHICH THE MOLTEN POLYETHYLENE IS BEING EXTRUDED, WHEREBY THE POLYETHYLENE PENETRATES THE FABRIC ONLY PARTIALLY AND SAID OPPOSITE SIDE OF THE FABRIC REMAINS EXPOSED, AND THEREAFTER COOLING THE ENTIRE RESULTING ASSEMBLY WHEREBY BOTH THE POLYETHYLENE AND THE FABRIC SHRINK AND THE POLYETHYLENE BECOMES FIRMLY MECHANICALLY INTERLOCKED WITH THE FABRIC, THE RESULTING COATED FABRIC BEING RESISTANT TO DELAMINATION UPON EXPOSURE TO 90% HYDROGEN PEROXIDE.
