Patent ID: 7985702

Claim:
A woven fabric for an airbag comprising a synthetic fiber woven fabric having a cover factor represented by the equation 1 of 2000 to 2500 in which at least one side thereof is coated with a synthetic resin, wherein air permeability of the woven fabric under a pressure difference of 100 kPa is 0.01 to 1.00 L/cm 2 /min, and a resin film is present at an upper part of a single yarn at a thickness of 2 μm or less on a central cross section of a weaving yarn part, while a resin film is present at an upper part of a single yarn at a thickness of 2 to 30 μm on a cross section at a border between weaving yarn parts, wherein the synthetic resin is a polyamide-based resin that includes a polyether compound of a number average molecular weight of 100 to 5000 as a soft segment. Cover factor=[warp density(number/2.54 cm)×√(warp fineness(dtex)×0.9)]+[weft density(number/2.54 cm)×√(weft fineness(dtex)×0.9)] (equation 1)
