ABSTRACT:
What is provided herein is a method of dispersing bundles of glass fibers for making uniform glass fiber mats by the wet-laid process. Well-dispersed glass fiber compositions are prepared herein by agitating chopped bundles of glass fibers in water with a small amount of a surfactant which is a polyethoxylated derivative of the amide condensation product of fatty acids and polyethylenepolyamines. The dispersions are formed at relatively high glass fiber consistencies, and at low surfactant concentrations.
