Hollow Weave Fabric for an Air Bag and Method of Producing the Same
First Claim
1. A hollow weave fabric for an air bag in which the periphery of a double-layer hollow weave portion is formed with a seam zone, wherein the warp yarn and the weft yarn forming the base fabric are each a poly(hexamethylene adipamide) fiber having a total size of 150 to 500 dtex, the double-layer hollow weave portion has a fabric weight of 120 to 350 g/m2 on one side, and the fabric shows a logarithmic decrement of 0.01 to 0.10.
