ABSTRACT:
There are provided a rubber-reinforcing glass fiber treatment agent capable of improving properties, in particular the oil resistance, of a rubber product, a rubber-reinforcing cord using the fiber treatment agent, and a rubber product having high oil resistance. The rubber-reinforcing glass fiber treatment agent consists essentially of a resorcin-formaldehyde water-soluble condensate and a butadiene-acrylonitrile copolymer latex; the butadiene-acrylonitrile copolymer latex has an acrylonitrile content of 31 to 55 wt % in terms of the weight of solids in the latex.
