ABSTRACT:
A sizing composition is provided for glass fibers to render the glass fibers more dispersible in aqueous solutions. The sizing composition has present an aqueous dispersion of cationic imidazoline; aliphatic, aromatic and/or polymeric ester; and polyethylene in an amount equivalent to an amount in the range of about 0.1 to about 1.5 weight percent of the aqueous sizing composition based on an approximately 30 percent active aqueous dispersion. The sizing composition may also contain, depending on the use, other components such as starch, lubricant, emulsifying agents, wetting agents, plasticizers, biocides and the like.
