ABSTRACT OF THE INVENTION An aqueous treating composition is provided for use with bulked glass fiber strand yarn to lock in the bulkiness of the yarn and to reduce any tendency of the yarn to produce lint and fly during subsequent process- ing operation. Also provided is the treated, bulked glass fiber strand yarn with the fried residue of the aqueous treating composition. The aqueous treating composition has a solid, thermoplastic, carboxylated, alkali-soluble polymer; elasticizing material, such as external internal or polymer plasticizers and an especially useful plasticizer being a liquid, thermoplastic, carboxylated, alkali-soluble low molecular weight polymer: alkali material including ammonia, amines, alkali metal, and alkaline earth metal hydroxides: and viscous lubricating material including polyoxyalkylene polyols, polyalkylene zlycole, alkoxylated fatty acids, alkyoxylated fatty acid esters and alkyoxylated sorbitan tristerate, and water. The aqueous treating composition is used in any manner know to those skilled in the art for treating bulked glass fiber strand yarn.
