ABSTRACT:
A method and composition are provided for producing an improved sized glass fiber strand that has a reduced tendency to form gummy deposits on fabrication machinery under high relative humidity conditions. The glass fiber strand is treated with a starch based forming size comprising about 50 to about 65 weight percent of the non-aqueous components of the composition being a starch containing cross-links that has been partially cooked along with a hydrogenated vegetable oil, or fatty triglyceride, cationic wetting agent, emulsifying agent, and water. The forming size composition can also contain a salt of a polyamino functional polyamide resin and a carboxylic acid and a wax and a coupling agent.
