A base fabric for non-coated air bags, in which both the warp and the weft or either of them comprise synthetic fiber multifilaments of flattened cross-section monofilaments having a degree of flatness of from 1.5 to 8.0 and having a monofilament fineness of at moat 10 dtex and a total fineness of from 200 to 1000 dtex, and which satisfies all the following (1) to (3): (1) its cover factor falls between 1700 and 2200; (2) its air permeability under low pressure, PL, is at most 0.1 cc/cm2/sec; and (3) its air permeability under high pressure, PH, is at most 20 cc/cm2/sec, has high tenacity and low air permeability necessary for air bags and is compactly foldable to save the housing space for it. |
