Abstract
A woven fabric for an airbag includes a synthetic fiber woven fabric having a cover factor of 2000 to 2500 in which at least one side thereof is coated with a synthetic resin. Air permeability of the woven fabric under a pressure difference of 100 kPa is 0.01 to 1.00 L/cm2/min. 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. 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. The synthetic resin can be a polyamide-based resin that includes a polyether compound of a number average molecular weight of 100 to 5000 as a soft segment.
