본 발명은 파이로 인플레이터에 대해서도 문제없이 사용할 수 있는 비코팅(non-coated) 에어백용 직물을 제공하는 것을 과제로 한다. 상기 과제를 해결하기 위해, 본 발명의 비코팅 에어백용 직물은 나일론 66을 90 중량% 이상 포함하는 합성섬유로 이루어지고, 직물의 경사(經絲)의 크림프율이 10.0%~13.0%이며, 직물의 위사(緯絲)의 크림프율이 6.0% 이하인 것, 합성섬유를 구성하는 나일론 66의 황산 상대점도가 3.15 이상 3.7 이하인 것, 합성섬유에 인 성분이 40 ppm 이상 200 ppm 이하 포함되는 것, 및 20℃×65%RH의 환경하에서 ASTM D6476에 기초하여 최고 압력이 80±5 kPa가 되는 조건에서 직물의 동적 통기도를 측정했을 때, 증압에서 감압으로 50 kPa에서 이행할 때의 직물의 이축 신장 변형 히스테리시스가 0.69% 이상 1.0% 이하인 것을 특징으로 한다.

    The present invention provides a non-coated woven fabric for air bag which can be used without problem even for pyro-inflators as well. A non-coated woven fabric for air bag according to the present invention comprises a synthetic fiber containing 90% by weight or more of Nylon 66, characterized in that crimping rate of warp of the fabric is 10.0 to 13.0% while crimping rate of woof of the fabric is 6.0% or less, relative viscosity of Nylon 66 constituting the synthetic fiber in sulfuric acid is 3.15 to 3.7, the synthetic fiber contains 40 ppm to 200 ppm of phosphorus component and, when dynamic air permeability of the fabric is measured at a maximum pressure of 80 ± 5 kPa based on ASTM D 6476 under the environment of 20°C x 65% RH, biaxial elongation strain hysteresis of the fabric during a transition from increased pressure to reduced pressure at 50 kPa is 0.69% to 1.0%.
