  • Polyester base fabric for airbag, polyester airbag, and method of manufacturing polyester base fabric for airbag
    Patent number: 10239481
    Abstract: A polyester base fabric for airbags woven from polyester fiber has an energy absorption amount in a warp direction (EW) when the polyester base fabric is elongated up to a stress of 118 N/cm and subsequently relaxed to a stress of 0 N/cm of 1.0 to 3.0 J/cm2; an energy absorption amount in a weft direction (EF) when the polyester base fabric is elongated up to a stress of 118 N/cm and subsequently relaxed to a stress of 0 N/cm of 1.0 to 3.0 J/cm2; and a ratio (EW/EF) of the energy absorption amount in the warp direction (EW) to the energy absorption amount in the weft direction (EF) of 0.5 to 2.0.
    Type: Grant
