    • [Object] The present invention relates to a polyester cord for reinforcement of rubber where heat-resistant adhesive property when exposed to high temperature for long time in a state of being embedded in a rubber composition or under a high-temperature atmosphere is significantly improved, stiffness of the cord is made soft to such a level which is no problem in terms of practical use in view of anti-fatigue property and also of molding and processing property of the rubber-reinforced product and a high elastic modulus is available; and a method for manufacturing the same.
      [Means to Solve] A method for the manufacture of a polyester cord for reinforcement of rubber, characterized in that , a polyester fiber material where an epoxy compound is previously applied in a stage of non-drawn yarn or drawn yarn or in a stage of twisted yarn cord so that an adhesively activated treatment is conducted is treated with a treating solution containing the three components of (A) an aqueous solution of blocked isocyanate, (B) a dispersion of epoxy resin and (C) resorcinol-formaldehyde-latex (RFL) mixed liquid by a single-stage treatment or a multi-stage treatment of two or more stages whereby adhesive property to rubber is endowed to said polyester fiber material.
    • 本发明涉及一种用于加强橡胶的聚酯帘线,其中在嵌入橡胶组合物或高温气氛中长时间暴露于高温下的耐热粘合性显着提高, 使帘线的刚度变得柔软到在耐疲劳性以及橡胶增强制品的成型加工性能方面没有问题,高弹性模量可用的水平, 及其制造方法。 [解决方案]一种用于制造用于增强橡胶的聚酯帘线的方法,其特征在于,在未拉伸纱线或拉伸纱线的阶段预先施加环氧化合物的聚酯纤维材料或在 (A)封端异氰酸酯水溶液,(B)环氧树脂分散体和(C)间苯二酚 - 甲醛胶乳(C)的三种成分处理溶液进行粘合活化处理, RFL)混合液,通过单阶段处理或多阶段处理两个或多个阶段,由此赋予橡胶粘合性赋予所述聚酯纤维材料。
