Polyethyleneterephthalate Yarn Method for Manufacturing The Same and Tire Cord Manufactured Using The Same

摘要

Disclosed is a polyethylene terephthalate yarn having a higher strength than a conventional polyethylene terephthalate yarn for tire cords without deteriorating the shape stability of the tire cord, a manufacturing method thereof, and a tire cord manufactured using the same. The polyethylene terephthalate yarn of the present invention comprises 300 to 1,000 filaments each having a fineness of 1 to 3 denier, strength of 8.2 g/d or more, elongation of 7% or less (elongation at 6.75 kgf load), and amorphous of 0.74 or more Has an orientation index (AOF).
