ABSTRACT:
Aqueous forming size compositions for treating a plurality of glass fibers include an oleophobic starch; a N-vinyl amide polymer; a wax component containing an ester formed from reacting (a) a monocarboxylic acid and (b) a monohydric alcohol; an emulsifying agent for the wax component; and a cationic lubricant different from the wax component. The forming size composition is essentially free of: (1) oleophilic starches; (2) polyolefin emulsions; and (3) preservatives selected from organometallic compounds, formaldehydes, derivatives and mixtures thereof. Glass fibers sized and coated with such compositions can be woven into fabrics.
