MUMBAI, India, Oct. 31 -- Intellectual Property India has published a patent application (202517093959 A) filed by Toyobo Co. Ltd., Osaka, Japan, on Sept. 30, for 'airbag-use polyester base fabric.'
Inventor(s) include Goto, Kota.
The application for the patent was published on Oct. 31, under issue no. 44/2025.
According to the abstract released by the Intellectual Property India: "The present invention addresses the problem of providing an airbag-use polyester base fabric that uses polyester fibers which can reduce carbon dioxide emissions, that makes improvements with regard to deterioration of stowability of the polyester base fabric, and that suppresses deterioration of air permeability after abrasion occurring during stowage and deployment. Provided as a means for solving this problem is an airbag-use polyester base fabric which is formed by applying 5 g/m2-25 g/m2 of a silicone resin to one side of a fabric that includes polyester fibers, and which has an average bending resistance in the warp and weft directions of 15 N or less, wherein: the polyester base fabric is characterized in that the first local maximum point of tearing strength in the warp direction and the weft direction is at least 300 N and, on a stress-strain curve with stress (N) as the vertical axis and strain (%) as the horizontal axis, obtained in tear tests, the average slope from an origin at a point where stress is 300 N in the warp and weft directions is 7.0 or less. The average air permeability in the warp direction and the weft direction after 200 cycles of a scrub test is 0.3 cc/cm2/sec or less."
The patent application was internationally filed on Mar. 27, 2024, under International application No.PCT/JP2024/012495.
