Abstract
A woven fabric useful for air bags capable of smoothly opening in an initial stage of inflation and having a high burst strength and an excellent safety satisfies all the requirement that (A) a stress strain curve of the woven fabric in at least one of the warp and weft directions is a substantially downwardly convex curve, where the elongation .epsilon. is in the range: 1%.ltoreq..epsilon..ltoreq.20%; (B) where the elongation .epsilon. is in the range: .epsilon..ltoreq.10%, the tensile strength S(.epsilon.) of the woven fabric is 10 to 100 kg/3 cm in both the warp and weft directions; and (C) the woven fabric has a tensile toughness of 2,000 to 4,000 kg.%/3 cm in both the warp and weft directions, the tensile toughness being represented by an area of a region, in a graph showing a stress-strain curve of the woven fabric in each of the warp and weft directions, defined by the stress-strain curve and an abscissa corresponding to a stress of zero.
