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.

A water-repellent and oil-resistant agent which has a high bio-based carbon content as the entire water-repellent and oil-resistant agent and furthermore which can impart sufficient water-repellency and oil-resistance to a treatment target is provided. A textile product in which the water-repellent and oil-resistant agent is attached, and a method for producing a textile product with the water-repellent and oil-resistant agent is provided. A water-repellent and oil-resistant agent comprising a non-fluorine compound as a main component and a liquid medium, wherein a bio-based carbon content according to ASTM D6866 is 40% or more. The non-fluorine compound has, for example, a hydrocarbon group having 7 to 40 carbon atom.
