Abstract
A fabric for an airbag includes a synthetic fiber woven fabric in which at least one side thereof is coated with a synthetic resin. A range of 0.1 to 10 g/m2 of the synthetic resin is adhered to the synthetic fiber woven fabric having a cover factor of less than 2000 and a FR value of 55% or more. Air permeability of the fabric under a pressure difference of 100 kPa after adhesion is 0.01 to 1.00 L/cm2/min. The synthetic resin can be a polyamide-based resin having a soft segment comprising a polyol with a number average molecular weight of 100 to 5000.
