Title:
REINFORCING POLYESTER CORD FOR RUBBERS AND PROCESS FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2006/093182
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a reinforcing polyester cord for rubbers which is remarkably improved in adhesiveness at high temperature as observed either when exposed to high temperature for a long time in a state embedded in a rubber compound or when placed under high-temperature atmosphere and enhanced in flexibility to such a level that the hardness of the cord is practically unproblematic in terms of fatigue resistance and processability of reinforced rubber products in molding and which has high elastic modulus; and a process for the production of the cord. [MEANS FOR SOLVING PROBLEMS] A process for the production of reinforcing polyester cord for rubbers, characterized by treating a polyester fiber material preliminarily activated in adhesion by applying an epoxy compound in either the yarn-making step or the twisted yarn cord step with a treatment fluid containing (A) an aqueous solution of a blocked isocyanate, (B) an epoxy resin dispersion, and (C) a resorcin-formaldehyde-latex (RFL) mixed fluid by a single- or multi-stage treatment process.
