An object of the present invention is to provide an airbag base fabric which is lightweight and thin and has low air permeability while retaining mechanical properties required of an airbag base fabric. An airbag base fabric satisfying the following characteristics of A to D:
(A) the cross-sectional deformation (WR), calculated by a formula (1), of multifilament warp threads constituting a textile is 4.0 to 6.0, WR = Major axis of warp thread cross section in textile / Minor axis of warp thread cross section in textile
(B) the cross-sectional deformation (FR), calculated by a formula (2), of multifilament weft threads constituting the textile is 2.4 to 4.0, and FR = Major axis of weft thread cross section in textile / Minor axis of weft thread cross section in textile
(C) the single fiber cross-sectional shape of the multifilament threads constituting the textile is substantially circular.
(D) The multifilament threads constituting the textile have total fineness of 145 to 720 dtex, single fiber fineness of 2 to 7 dtex, and tensile strength of 6.5 to 8.5 cN/dtex. |
