Airbag Fabric
Fabric for an airbag, comprising warp threads and weft threads, in particular using multifilaments, characterized by a weave density greater than the 95% Professor Walz standard. It can also have a permeability (LD) of less than 3 l/dm 2 /min (at 500 Pa differential pressure) pursuant to ISO 9237, and can be characterized by a warp/weft insertion ratio greater than 1.
