Weavable textile glass strand

Wound, weaveable and twisted textile glass fiber strand that is a unitary bundle of a multiplicity of glass fibers having thereon the heat or solvent cleanable, dried residue of an aqueous nonstarch, forming size composition that is an aqueous dispersion at ambient temperatures followed by subsequent drying without the addition of other chemical compounds, wherein on a weight basis the aqueous nonstarch, forming size composition, comprises:

• at least 45 percent and up to around 90 percent but always as the predominant component of the nonaqueous components of the composition of at least one wax that is a solid at ambient temperatures and is in a solid-in-water dispersion or emulsion and is selected from the group consisting of microcrystalline wax, petroleum wax, and mixtures and blends thereof, and
• a cationic lubricant and a second lubricating material selected from the group consisting of:
• with a molecular weight in the range of 300 to 12,000, polyalkylene polyols, and glycols wherein each of the lubricating materials are present in an amount less than the amount of the wax.
