Abstract
To provide a fiber bundling agent containing: a vinyl ester resin (A) having an alkoxy polyoxyalkylene structure, a urethane bond, a (meth)acryloyl group, and an epoxy group; and an aqueous medium, in which the vinyl ester resin (A) has an epoxy equivalent of 3,500 g/eq to 11,000 g/eq. Since the fiber bundling agent is excellent in bundling properties and in interfacial shear strength between fiber resins, the fiber bundling agent is suitably used for production of a fiber material capable of imparting excellent strength to a molded product.
