摘要
The present invention relates to a poly(ethyleneterephthalate) drawn fiber, which is able to provide a poly(ethylene terephthalate) tire-cord showing superior strength and dimensional stability without a PCI process after tire vulcanization, a poly(ethylene terephthalate) tire-cord and a manufacturing method thereof. The poly(ethyleneterephthalate) drawn fiber has a predetermined L/S value of 2.0 kg/% or more after heat treatment at a temperature of 180°C under an initial load of 0.02 g/d for 2 minutes.
