    摘要： The present invention addresses the problem of providing: a coated fabric for airbags that is less likely to have yarn slippage after being sewn, and that can also be compactly stored; and an airbag using the coated fabric. As means for achieving this object, a coated fabric for airbags that has a crimp ratio of 12% or more in the warp direction and a crimp ratio of 6% or less in the weft direction is provided.

    摘要： The present invention provides a base fabric for air bag which is excellent in terms of light weight and compactness and which is excellent in terms of an impactor characteristic to pyro-inflator and is particularly suitable for a driver seat and a passenger seat.
    There is disclosed a non-coated base fabric for air bag characterized in that maximum value of inner pressure of a woven fabric in measurement of dynamic air permeability at 50 to 65°C is 70 to 100 kpa and biaxial strain rate of the base fabric at that time is 2.9 to 4.0%. Preferably, a yarn which constitutes the woven fabric is Nylon 66 fiber, content of an oil component remaining in the woven fabric is 0.04 to 0.60% by weight to the woven fabric, main ingredient of the oil component is an olefin type polymer having a melting point of 60°C or lower, and the woven fabric contains 20 to 200 ppm of a phosphorus component.

    摘要： 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%.
