STEEL CORD FOR REINFORCING RUBBER ARTICLE

Title:

STEEL CORD FOR REINFORCING RUBBER ARTICLE

Document Type and Number:

WIPO Patent Application WO/2016/017654

Kind Code:

A1

Abstract:

Provided is a steel cord for reinforcing a rubber article. The steel cord achieves higher cord strength and rubber penetration characteristics (anti-rusting characteristics) as well as higher shear resistance. The steel cord for reinforcing a rubber article comprises one core strand (11) having a layered twisted structure formed by twisting together a plurality of steel filaments (1), and also comprises a plurality of sheath strands (12) having a layered twisted structure formed by twisting together a plurality of steel filaments (2), the sheath strands being twisted together around the core strand. The average value (Lc) for the amount of space between outermost-layer sheath filaments that constitute the outermost-layer sheath of the core strand is 0.073-0.130 mm, and the number of outermost-layer sheath filaments is 7-10.
