MARINE POLYESTER FIBER, AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a marine fiber used in the anchoring of an oil prospecting ship for oil field development in the deep sea and the like, and particularly, to a marine polyester fiber which is a fiber comprising a polyester fiber surface-treated with an oil component and has a certain range of a work recovery or a creep ratio in a cycling test according to an ASTM D885 method of the standards of the American Society for Testing And Materials, and a preparation method thereof. The marine polyester fiber of the present invention can be conveniently used due to a remarkably reduced weight compared with known wire ropes, simultaneously provides excellent mechanical strength, abrasion resistance and shape stability when applied to a marine fiber, and can be used for a long time.
