Production method of coating the base fabric for coating base fabric and an air bag for an air bag

摘要

The present invention is coated fabric for airbags which is obtained by applying a silicone resin to at least one surface of woven fabric constituted of synthetic fiber filaments, in an amount of 20 g/m 2 or less. The coated fabric is characterized in that in the uncoated base fabric, the warp crimp ratio is less than the weft crimp ratio, the warp crimp ratio is 4% or less, and the difference between the warp crimp ratio and the weft crimp ratio is 0.8-3.0%, and that the coated fabric has a air permeability, measured at a differential pressure of 100kPa, of 0.02 L/cm 2 /min or less. Although the amount of the resin applied is 20g/m 2 or less, extremely low air permeability is ensured.
