ABSTRACT:
Chemically treated glass fibers of the present invention perform well as wet chopped strands of glass fibers and are useful in producing glass fiber paper. In one aspect the chopped strands of glass fibers have an aqueous chemical treatment comprised of at least one water soluble, ungelled polymer having an effective viscosity, an effective film-forming capability and an effective molecular weight. In another aspect the chemically treated glass fibers have a chemical treating composition having a polyoxyethylene polymer as the water soluble and ungelled polymer with an effective film forming molecular weight along with water soluble, dispersible or emulsifiable aldehyde-condensate-reactable, polymeric agent, cationic lubricant or lubricating surfactant, aldehyde-condensate-reactable organo silane coupling agents and a carrier like water. The amount of the reactable polymeric agent is an effective white water compatible amount, where this agent is a polymer like either polyacrylamide or polyamide or a mixture of these. The aldehyde-condensate-reactable organo silane coupling agent can be an alkoxylated gamma aminoalkyltrialkoxy silane, a polyamino organo silane, mercapto functional organo silane or a ureido functional organo silane or a mixture thereof.
