    • The present invention discloses a high strength low shrinkage polyester drawn yarn used as industrial yarns and a process or producing the same. The strength low shrinkage polyester drawn yarn has a thermal relaxation stress change ratio of 5 to 100% and a thermal relaxation stress area ratio of 50 to 140% on a thermal relaxation and shrinkage stress curve with a final temperature set to 170% C. The process for producing a high strength low shrinkage polyester drawn yam by a direct spin draw (DSD) process in which a quenching delay region I is mounted, wherein the high strength low shrinkage polyester drawn yarn is produced in such methods that a spinning oil is attached to the yarn being spun with an oiling apparatus 8 mounted at the position 500 to 1,500 mm below from the lower bottom surface of the insulating board 3, the relaxation stress of the yarn is controlled with one or tow tension guides 9 mounted between Godet rollers of a relaxation region III, or both oiling apparatus 8 and tension guides 9 are mounted.
    • 本发明公开了一种用作工业纱线的高强度低收缩聚酯拉伸丝及其制造方法。 强度低收缩聚酯拉伸丝的热松弛应力变化率为5〜100%,热松弛应力面积率为50〜140%,最终温度设定为170%。热松弛应力面积率为50〜140%。 通过直接旋转拉伸(DSD)工艺生产高强度低收缩聚酯拉丝纱线的方法,其中安装淬火延迟区域I,其中高强度低收缩聚酯拉伸纱线以纺丝油附着的方式制备 对于从绝缘板3的下底面安装在500〜1500mm以下位置的上油装置8的纱线,通过一个或多个牵引张力导向装置9来控制纱线的松驰应力, 松弛区域III,或两个涂油装置8和张紧导向装置9。
