- Example 4 In the same manner as in Example 4, but instead of the polydimethylsiloxane treated with a spinning emulsion containing 30% by weight of mineral oil and 70% by weight of solvent to prepare a polyester yarn by surface treatment on the polyester fiber It was.
- Creep rate was measured by the following method about the polyester yarn manufactured according to the said Examples 1-5 and Comparative Examples 1-2, and the measurement result is shown in following Table 2. Creep Rate Measurement
- Creep rate was measured using a creep tester as shown in FIG. 4.
- Creep Rate (LL 0 ) / Lo X 100
- L is the length deformed after applying the load
- Lo is a yarn length of 1.4 m when the sample is placed in the creep tester.
- the polyester yarns of Examples 1 to 5 and Comparative Examples 1 and 2 were subjected to different stretching processes under measurement conditions as shown in Table 2 below, and creep was measured.
- the polyester yarns of Examples 1 to 5 and Comparative Examples 1 and 2 were loaded with 3.5 g / d and 6.5 g / d at a temperature of 25 ° C. After 5 to 10 cycling tests were performed, the Work returned during Recovery and Total Work done in Extension were measured, and each polyester yarn was measured according to the following Equation 2 from the measured values.

- the polyester yarns of Examples 1 to 5 surface-treated with an oil component containing a high content of a polysiloxane compound according to the present invention, mineral oil or ethylene oxide addition, which is a conventional fiber treatment emulsion It can be seen that the creep rate is much lower by up to about 4.8% compared to the polyester yarns of Comparative Examples 1 to 2 surface-treated with diol esters. In particular, by securing such excellent creep properties, it can be seen that the polyester yarn of the present invention has remarkably excellent properties in strength, strength retention, and the like.

At this time, the strong retention rate is only 55% to 60%, so that the mechanical strength, abrasion resistance, and shape stability of the marine spray can be remarkably reduced, and thus, it may be seen that complete cutting may occur when used for a long time.
- polyester yarns of Examples 1 to 5 have at least 1.5 times better abrasion resistance than the polyester yarns of Comparative Example 1 surface-treated with mineral oil which is a conventional fiber treatment emulsion. Furthermore, in Comparative Example 2 which was surface treated with ethylene oxide addition diol ester In the case of polyester yarns, it can be seen that the surface lubricity is poor and the wear resistance is remarkably inferior.
- the polyester yarn of the present invention is excellent in both high strength, wear resistance and work recovery characteristics, and can be conveniently used as a fiber rope of significantly reduced weight compared to the conventional wire rope when applied as a marine yarn, It can be used for a long time without the occurrence of partial cutting by minimizing the generation of frictional heat or deformation due to the change of external environment.
