Abstract
A coating composition substantially prevents fraying of glass fiber yarn packages. The composition is composed of an aqueous solution of a resin formed of the hydrolysis product of a copolymer of vinyl aromatic monomer and maleic anhydride, an organo silane glass fiber anchoring agent and an effective amount of a water-soluble pyrrolidone-containing polymer sufficient to form a protective film over the glass fiber.
