    摘要： This disclosure relates to high strength polyester fiber for industrial application such as a seat belt, webbing and the like, particularly to polyester fiber having elongation of 0.4% or more at stress of 1.0 g/d, elongation of 3.5% or more at stress of 4.0 g/d, and elongation of 6.0% or more at stress of 7.0 g/d, as measured at room temperature, and a method for manufacturing the same. The polyester fiber according to the present invention has high strength, low modulus and high elongation thereby securing excellent mechanical properties, and thus, a seat belt having excellent impact absorption rate, and remarkably improved abrasion resistance and heat resistant breaking strength retention may be manufactured.

    摘要： The present invention relates to a polyester fiber that can be applied to a fabric for airbag, particularly, to a polyester fiber having an elongation of 0.4% or less at the stress of 1.0 g/d, an enlongation of 4.0% or less at the stress of 4.0 g/d, and an enlongation of 7.0% or less at the stress of 7.0 g/d, and an initial modulus of 105 to 130 g/d; a method of preparing the same; and a fabric for airbag prepared therefrom. Since the polyester fiber of the present invention decreases stiffness remarkably and secures superior mechanical properties by having a high strength, high elongation, and high shrinkage, it is possible to provide superior packing property, dimensional stability, and air-tight effect, and to protect passengers safely by minimizing the impact applied to the passengers, when it is used for the fabric for airbag.
