PROBLEM TO BE SOLVED: To provide a non-coated base fabric for an air bag coping with elevation of temperature of inflator gas.SOLUTION: There is provided a woven fabric for an air bag in which the single fiber fineness of a synthetic fiber is 1 dtex and more and 4 dtex or less, the crimp ratio of warp of the woven fabric is 10.0-13.0%, the crimp ratio of weft of the woven fabric is 6.0% or less, nylon 66 constituting the synthetic fiber has a sulfuric acid relative viscosity of 3.15 or more and 3.3 or less, the synthetic fiber contains a phosphorus component in an amount of 10 ppm or more and 60 ppm or less, and when dynamic air permeability of the woven fabric is determined in an environment of 20°C and 65%RH under a condition that the maximum pressure is 80±5 kPa based on ASTM D6476, the biaxial extension strain hysteresis of the woven fabric is 0.69% or more and 1.0% or less at 50 kPa in a transition from a state of increasing pressure to a state of decreasing pressure. |
