Patent ID: 8920880

Claim:
A method for producing an air bag base fabric comprising the steps of preliminarily treating at least one surface of a textile fabric composed of a polyamide fiber with (F) an organosilicon compound containing an epoxy group and an alkoxy group bonded to a silicon atom in one molecule to prepare a substrate which is an air bag textile fabric composed of the polyamide fiber and containing 0.01 to 5 parts by weight of the organosilicon compound in relation to 100 parts by weight of the textile fabric before the treatment, coating the at least one treated surface of the substrate with a liquid silicone rubber coating composition having a viscosity at 25° C. of up to 50 Pa·s comprising (A) 100 parts by weight of an organopolysiloxane containing at least 2 alkenyl groups bonded to silicon atoms per molecule, (B) an organohydrogenpolysiloxane containing at least 2 hydrogen atoms bonded to silicon atoms in one molecule at an amount such that the number of the hydrogen atoms bonded to the silicon atoms in this component is 1 to 10 per one alkenyl group bonded to the silicon atom in the component (A), (C) an effective amount of an addition catalyst, (D) 0 to 50 parts by weight of a fine powder silica having a specific surface area of at least 50 m 2 /g, and (E) 0.01 to 5 parts by weight of an organometallic compound selected from titanium compounds and zirconium compounds, but free of component (F), and curing the composition to form a silicone rubber coating layer on at least one surface of the substrate.
