Through using special construction spinneret and choosing two kinds of seawater repellent functional oil, the high abrasion, high tenacity and low elongation polyester industrial yarns for the ocean mooring ropes were spun. The spinning processes by which the amount of oil could be effectively reduced and the abrasive resistance of products could be improved were explored, and the abrasive resistance of high tenacity and low elongation polyester industrial yarns for ocean mooring ropes was evaluated by a set of wet friction tester with different load which was independently developed and designed.
