REINFORCING PLY FOR ARTICLES MADE OF AN ELASTOMERIC MATERIAL, PREFERABLY FOR PNEUMATIC VEHICLE TIRES AND PNEUMATIC VEHICLE TIRES

摘要

A rubberized reinforcing ply for articles made of an elastomeric material, specifically vehicle tires, which have a plurality of parallel tire cords spaced apart from one another and the tire cords are hybrid cords of at least two multifilament yarns twisted together. The first multifilament yarn is a viscose multifilament yarn and the other multifilament yarn is a non-metallic multifilament yarn made of a material that is not identical to the first multifilament yarn. The viscose multifilament yarn is conditioned in a standard atmosphere according to DIN EN ISO 139-1:2005 and after conditioning has a yarn titer<1100 dtex and a tensile strength≧45 cN/tex. The hybrid cord has a core titer≦3000 dtex.

主权项

1. A rubberized reinforcement ply for articles made of an elastomeric material, the reinforcement ply comprising:
a multiplicity of mutually spaced-apart strength members in a parallel arrangement, wherein the strength members are hybrid cords composed of at least two multifilament yarns twisted with one another, the first multifilament yarn being a viscose multifilament yarn and the further multifilament yarn being a nonmetallic multifilament yarn which is composed of a material not identical with the first multifilament yarn, wherein the viscose multifilament yarn after conditioning in a DIN EN ISO 139-1:2005 standard atmosphere has a yarn linear density<1100 dtex and a tenacity of ≧45 cN/tex, and wherein the hybrid cord has a cord linear density≦3000 dtex.
