<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a polyester fiber cord for rubber reinforcement having improved heat-resistant adhesion and heat-resistant mechanical strength retention between a polyester fiber and a rubber when exposed to high temperature, which cannot be achieved by a conventional technique, and having fatigue resistance sufficient for practical use. <P>SOLUTION: Provided is a manufacturing method of a polyester fiber cord for rubber reinforcement formed by coating with a first treatment agent containing the three kinds of at least (A) an aliphatic polyepoxide compound having an epoxy equivalent of 100 to 200, (B) a blocked polyisocyanate compound, and (C) a vinylpyridine-styrene-butadiene rubber latex having a glass transition point of -30 to 0°C and by coating a second treatment agent containing a resorcine-formalin-rubber latex (RFL) as its outer layer, where a first bath hot stretch tension is treated at 0.05 to 0.40 cN/dTex. <P>COPYRIGHT: (C)2013,JPO&INPIT |
