摘要： A polyester filamentary yarn having a novel internal microstructure, a polyester tire cord produced from the yarn and a process for production thereof are provided. The polyester yarn of the present invention comprising at least 90 mol % polyethylene terephthalate and having a fineness of 3 to 5 denier per filament, wherein said yarn satisfies the following i) SIMILAR iii) characteristics, after it has been treated for 3 minutes at temperature of 240 DEG C, tension of 0.1 g/d, said yarn satisfies the following iv) SIMILAR vii) variations of microstructural physical properties: i) a density of 1.38 SIMILAR 1.39 g/cm , ii) a birefringence index in amorphous portions of 0.06 SIMILAR 0.09, iii) tan delta peak temperature of 140 DEG C and below, iv) the increment of a percent crystallinity ( DELTA Xc) of 10 SIMILAR 20 wt.%, v) the decrement of an amorphous orientation coefficient ( DELTA Fa) of at least 0.05, vi) the increment of a long period value ( DELTA LP) of at least 10 ANGSTROM , and vii) the decrement of tan delta peak temperature ( DELTA tan delta peak) of at least 5 DEG C. The filamentary yarn is dipped in a rubber solution to produce a tire cord which exhibits excellent dimensional stability and fatigue resistance when it has been incorporated in a rubber matrix of a tire.
