PURPOSE:To obtain high-tenacity woven fabric having low air permeability having excellent storing properties and high tenacity without causing fraying and loosening in cutting and processing. CONSTITUTION:This woven fabric having low air permeability is high-density woven fabric comprising multifilament yarn of synthetic fiber having 25-450 denier fineness and g 6.5 g/d tenacity, subjected to calendering processing and stuck with a resin on the surface or in the interior and has $ 0.3 mm thickness, >=0.04 overlapping ratio (Wo/Wf) as a ratio of width (Wo) of a zone in which adjoining multifilaments are superimposed and width (Wf) of multifilaments, <=75mm bending resistance of both warp and weft and <=0.3cm<3>/cm<2>/sec air permeability at 0.5 inch pressure difference. |
