| 摘要 |
The present invention relates to a polyester fiber that can be applied to a fabric for an airbag, and particularly, to a polyester fiber having a crystallinity of 43% to 55%, an amorphous orientation factor (AOF) of 0.2 to 0.8, and a long period of 140 to 180 A, a method of preparing the same, and a fabric for an airbag prepared therefrom. Since the polyester fiber of the present invention remarkably secures high strength and high elongation, it is possible to provide superior packing properties, dimensional stability, and gas barrier effect, and to protect occupants safely by minimizing the impact applied to the occupants, when it is used for the fabric for an airbag. |
