Product reinforcing fabric and two-component weft yarn useful therein

摘要

A reinforcing fabric comprising a web of tire cords maintained in spaced relationship with sheath-core weft yarns having a cotton sheath about a core of spin-oriented polyester filaments. The weft yarns have a high initial modulus and a high break elongation which is substantially retained after heat aging the yarn at 450 DEG or 475 DEG F. The fabric is particularly useful as reinforcement in radial tire constructions.
