Abstract

A gastight woven fabric sheet for air bags having no risk of burning a person due to formation of gas-permeable perforations and gas flowing out when the air bag is inflated, a high burst strength due to a reinforcing effect by adhesion, and a satisfactory feel, comprising a woven fabric composed of a plurality of warps and wefts each comprising a polyester multifilament having a yarn thickness of 200 to 550 deniers and a twist multiplier of 3,000 or less, and having a smooth surface formed by a calendering and a non-smoothed opposite surface thereof, the woven fabric having a gas-permeability function (ml/cm2/sec) of 7.874 p to 78.74 p (wherein p is a pressure between 0 to 0.03 kg/cm2G); a radius R1 (mm) of curvature of a smoothed surface side half portion of a cross-sectional profile of a warp or weft yarn located in the smoothed surface portion of the fabric, larger than a radius R2 (mm) of curvature of an opposite side half portion of a cross-sectional profile of the above-mentioned warp or weft yarn and than a radius R3 (mm) of curvature of a non-smoothed surface side half portion of a cross-sectional profile of a warp or weft yarn located in the non-smoothed surface portion of the woven fabric, which R3 is in the range of from 0.5 to 3.5; a difference in average deviation of 0.0005 or more between surface frictional coefficients of the smoothed surface and the non-smoothed surface of the woven fabric; a difference in average deviation of 0.5 µm or more between surface roughnesses of the above-mentioned surfaces;
and a fiber packing of 70 to 85%.
