PURPOSE: Marine polyester yarns is provided to maximize a lifespan of the yarns by minimizing frictional heat production according to change of external circumstances, and to reduce drastically the weight of the polyester yarns. CONSTITUTION: Marine polyester yarns include a polysiloxaen compound of a chemical formula 1 processed on the surface of the polyester fiber. In the chemical formula 1, R^1, R^2, R^3, R^4, R^5, R^6 and R^7 includes the same components, different hydrogen, alkyl groups of C1~C20, or aryl groups of C1~C20. n is the fixed number of 1~5,000. The viscosity of the polysiloxaen compound is 5 ~ 35,000 cst. The polysiloxaen compound is one or more selected from a group consisting of polydialkylsiloxanes and polyalkylarylsiloxane. The polysiloxaen compound is one or more selected from a group consisting of polydimethylsiloxane, polydi butyl siloxane and polymethylphenylsiloxane. |
