Title:

FABRIC FOR NON-COATED AIRBAGS

Document Type and Number:

WIPO Patent Application WO/2013/168730

Kind Code:

A1

Abstract:

The present invention provides a fabric for non-coated airbags, which can also be safely used for pyro inflators. This fabric for non-coated airbags is characterized by comprising synthetic fibers containing at least 90 wt% of nylon 66. The fabric for non-coated airbags is further characterized in that: the crimp rate of the warp of the fabric is 10.0% to 13.0%, and the crimp rate of the weft of the fabric of not more than 6.0%; the sulfuric acid relative viscosity of the nylon 66 constituting the synthetic fibers is 3.15 to 3.7; the synthetic fibers have a phosphorus component of 40 ppm to 200 ppm; and when the dynamic air permeability of the fabric is measured on the basis of ASTM D6476 at a maximum pressure of 80 ± 5 kPa in an environment at 20°C and 65% relative humidity, the biaxial elongation strain hysterisis of the fabric when transitioning from an increased pressure to a reduced pressure at 50 kPa is 0.69% to 1.0%.
