Document Type and Number:
WIPO Patent Application WO/2004/031472
Kind Code:
A1
Abstract:
The invention relates to a coated base fabric for air bags which exhibits low air permeability and excellent heat resistance and is capable of being stored in a compact state and excellent in the adhesion between fabric and resin coating film; air bags made by using the coated base fabric; and a process for the production of the fabric. Specifically, the invention relates to a coated base fabric for air bags which consists of a fiber fabric coated with a resin on at least one surface, characterized in that at least part of the single yarns constituting the fabric is enclosed with the resin and at least part of the single yarns constituting the fabric is not enclosed with the resin; air bags characterized by being made by the use of the coated base fabric; and a process for the production of a coated base fabric for air bags, characterized by applying a resin solution having a viscosity of 5 to 20 Pa s (5,000 to 20,000cP) to a fiber fabric with a knife coater equipped with an acute-angle doctor knife at a contact pressure between the knife and the fabric of 1 to 15N/cm.
