Coated fabric for air bag is obtained by applying a resin of elastomer on at least one side of a cloth fabric made from synthetic fiber.And method for manufacturing a coated fabric for an air bag.

摘要

The present invention provides a coated fabric for an air bag obtained by applying an elastomer resin onto at least one side of a woven fabric made from synthetic fiber, characterized in that the applied amount of the elastomer resin is 25 to 60 g/m 2 , that an average resin thickness on warp and weft at head top of the woven fabric surface is 8 µm to 45 µm, and that number of foams having diameter of 30 µm or larger is 100 or more/cm 2 on the surface of a resin layer. The coated fabric for an air bag has a high heat resistance to such an extent that it can be used well for a reinforcing fabric for an air bag, has a heat resistance in such a level that it can be used for an inflator attachment port having high thermal load even in an applied amount of 60 g/m 2 or less, and prevents, at the same time, a blocking property caused by contact between the coated surfaces.
