ABSTRACT:
A simplified aqueous sizing composition utilizing a variety of components achieves improved stability, wettability and strength characteristics. The composition utilizes one or more aqueous, soluble, dispersible or emulsifiable bisphenol A type polyester film forming polymers with an epoxy containing film forming copolymer compatible with and soluble in the matrix polymer. One or more organo-silane coupling agents are also utilized. The sizing composition preferably includes a single nonionic surfactant in conjunction with a cationic amidated polyamine lubricant. One or more anti-static agents, generally cationic organic quaternary ammonium salts having one or more alkoxy moieties, are utilized in an effective anti-static amount. An anti-foaming agent may also be utilized for the prevention or suppression of foam during the mixing process. The improved stability and wettability characteristics of the aqueous sizing composition are preferably achieved through the use of a single epoxidized surfactant. Compositions formed from this surfactant are effective at one-half the surfactant level and retain their static emulsion stability for 48 hours or more. This is accompanied by a 50 percent improvement in dry sliver abrasion with no apparent negative effects on the mechanical properties of the resultant glass fiber.
