<p>More flexible bundles of high modulus, low elongation fibers are produced by the impregnated bundles and process of the present invention. The flexible bundle of fibers comprise a plurality of fibers having a first treatment of a moisture-reduced residue of an aqeuous chemical composition and a second teatment of a moisture-reduced, partially cured impregnant of an aqueous chemical coating composition. The individual fibers in the impregnated bundle were first treated with an aqueous sizing composition having at least a fiber protectorant and optionally an antistatic agent and/or coupling agent. The impregnating composition has one or more water soluble, dispersible or emulsifiable elastomeric polymers that are essentially free of hydrocarbon diene and chlorine functionalities, and one or more crosslinking materials that are water soluble, emulsifiable or dispersible lubricants, plasticizers, polymeric materials, waxes, diene-containing latices and flame retardants. The flexible impregnated bundles of glass fibers are useful in producing woven and nonwoven fabrics where the fabrics can be coated with polymeric films.</p> |
