Abstract
The purpose of the present invention is to provide a fabric for an air bag that, during high-pressure deployment at high speed, maintains low air permeability as an air bag and is capable of maintaining the low air permeability even after exposure to heat. This fabric for an air bag comprises a synthetic fiber and is characterized by the contact angle of a circumscribed circle at intersecting sections in which the warp thread and the weft thread come in contact in the cross section of the fabric is at least 80° in both the warp thread direction and the weft thread direction.
