PROBLEM TO BE SOLVED: To obtain a coating layer having a preferable adhesive strength for adhesion between a glass fiber cord and rubber, and further, the coating layer maintains an initial strength of adhesion when used for a heat-resistant belt for a long time. And it aims at providing the glass fiber for rubber reinforcement excellent in dimensional stability. SOLUTION: A glass fiber coating coating solution in which an emulsion of an acrylic ester resin, an aqueous solution of a monohydroxybenzene-formaldehyde condensate, and an emulsion of a vinylpyridine-styrene-butadiene copolymer is mixed is applied to a glass fiber cord. A glass fiber for rubber reinforcement characterized by being dried and provided with a coating layer. [Selection figure] None |
