NEW BIOELASTIC TIRE CORD FROM POLYESTER AS A REINFORCING BRACKER LAYER

摘要

The present invention relates to a novel polyester tire cord reinforcement which has bi-elastic tensile properties. The tire cord includes at least two cord plies, and there is a spacing between the cord plies. Such a novel bi-elastic polyester tire cord improves high speed durability and significantly eliminates flatspotting when used as a cap ply in pneumatic radial tires.
