POLYESTER FIBER AND POLYESTER FABRIC COMPRISING SAME

摘要

The present invention relates to polyester fiber usable for fabric for an airbag, and more particularly, to polyester fiber for an airbag and to a polyester fabric comprising same, in which the polyester fiber has a modulus of 60g/d or less in the elongation range of 2.0 to 3.0%, a modulus of 45 to 70 g/d in the elongation range of 9.0 to 11.0%, and a modulus of 60g/d or more in the elongation range of 12.0 to 14%. When used in fabric for an airbag, the above-described polyester fiber enables the airbag to be easily installed in a vehicle, provides excellent protective performance for a passenger, and effectively prevents the escape of air, and minimizes the impact applied to a passenger so as to safely protect the passenger upon the occurrence of a vehicular crash.
