The present invention relates to a fabric for an uncoated airbag which is excellent in dynamic low air permeability characteristics and also excellent in internal pressure retention characteristics. The high-density fabric for the airbag is characterized by being formed from synthetic fiber multifilament yarns, having a tensile strength in a twill direction of 400-700N, an average dynamic air permeability (ADAP) of 500 mm/s or less as measured by ASTM D6476, and a dynamic air permeability curve index (Exponent) of 1.5 or less as measured by the specification.
本发明涉及动态低通气特性优异、而且内压保持特性也优异的非涂层安全气囊用织物。本发明的安全气囊用高密度织物,其特征在于,其是由合成纤维复丝纱形成的安全气囊用织物,斜纹方向的拉伸强力为400~700N,基于ASTM D6476测定的平均动态通气度(ADAP)为500mm/s以下,并且基于该规定测定的动态通气度曲线指数(Exponent)为1.5以下。
