Provided is a woven fabric for a bag-woven airbag, the woven fabric being suitable for an airbag having excellent storability and excellent cut resistance when the airbag is deployed while satisfying internal pressure retention and wear resistance characteristics required for the airbag. The woven fabric for a bag-woven airbag according to the present invention is characterized in that the value of a dynamic tear characteristic P, which is represented by the following formulae: Px = {E/(Tx * Fx)} * 1000, Py = {E/(Ty * Fy)} * 1000, and P = Px + Py, in at least a partial region of a double-layer bag-woven structure is 1.5 or more. (In the formula, E is the kinetic energy (J) of the block and the cutter in the dynamic tear test (performance level 3) described in JIS T 8050, Tx and Ty are respectively the average value (mm) of the tear lengths in the warp and weft directions in the dynamic tear test (performance level 3) described in JIS T 8050, and Fx and Fy are respectively the fineness (dtex) of the warp and weft constituting the double-layer pouch weave.

    提供一种袋织气囊用机织物,其适合于满足对气囊要求的内压保持性、耐磨耗特性,同时收纳性优异且气囊展开时的耐割伤性也优异的气囊。本发明所述的袋织气囊用机织物的特征在于,双层袋织组织的至少一部分区域的用下式:Px={E/(Tx×Fx)}×1000、Py={E/(Ty×Fy)}×1000、P=Px+Py表示的动态撕裂特性P的值为1.5以上。{式中,E为JIS T 8050中记载的动态撕裂试验(性能水准级别3)中的块体和刀具的动能(J),Tx和Ty分别为JIS T 8050中记载的动态撕裂试验(性能水准级别3)中的经纱和纬纱方向的撕裂长度的平均值(mm),Fx和Fy分别为构成该双层袋织组织的经纱和纬纱的纤度(dtex)}。
