The present invention relates to a polyester fiber having high tenacity and high elongation, which is used for a rope for anchorage, mooring, towage, etc. of a ship. More specifically, the present invention relates to a polyester fiber having the elongation of 6.8% or more at 50% of the maximum load (MBL) measured at room temperature, and a polyester fiber rope comprising the same. The polyester fiber of the present invention can secure excellent shape stability, mechanical properties and abrasion resistance as well as high tenacity and elongation. Thereby, it can be used to prepare the fiber rope which may minimize the yarn breaking even under the changes of external environments such as wild marine, severe ship rolling, etc., remarkably improve the shock absorption performance, maintain the performance as a rope after exposure to the long-term deformation, and thus secure the sufficient safety along with the excellent life time of rope. |
