Abstract:
1. A method for producing a stretch composite fabric comprising: laminating a sintered expanded porous polytetrafluoroethylene film to a stretch cloth in a non-stretched state to form a laminate, said expanded porous polytetrafluoroethylene film being in a flat state; stretching the laminate in a planar direction so as to increase the area of the laminate to 1.4 times or more; and shrinking the laminate by removing the stretching force, wherein said flat state of said sintered expanded porous polytetrafluoroethylene film is measured by a ratio (L wherein said ratio is 1.2 or less.
