AQUEOUS CHEMICAL COMPOSITION FOR GLASS FIBER STRAND YARN TREATMENT AND BULKED GLASS FIBER STRAND YARN MATTER TREATED THEREWITH

摘要

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 processing operations. Also provided is the treated, bulked glass fiber strand yarn with the dried residue of the aqueous treating composition. The aqueous treating composition has a solid, thermoplastic, carboxylated, alkali-soluble polymer; plasticizing 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 glycols, alkoxylated fatty acids, alkyoxylated fatty acid esters and alkyoxylated sorbitan tristerate, and water. The aqueous treating composition is used in any manner known to those skilled in the art for treating bulked glass fiber strand yarn.
