Glass fiber dispersions for making uniform glass fiber mats by the wet-laid process

Claim 1

In the manufacture of uniform glass mats at a high rate of production by the wet-laid process, the improved method which comprises forming an aqueous dispersion of glass fibers by mixing bundles of said fibers of about 1/4 to 3 inches in length in an aqueous medium at a fiber consistency of about 0.001 to 3.0% with about 5-500 ppm of an amine oxide surfactant having the formula: ##STR15## where R 1 , R 2 , and R 3 are selected from the group consisting of aliphatic and aromatic hydrocarbon radicals, substituted or unsubstituted, containing between 1 and 30 carbon atoms, being the same or different, the sum of R 1 , R 2 and R 3 being between about 14 to 40, thereby to substantially disperse said bundles into individual fibers within the aqueous medium, and, passing said dispersion through a mat-forming screen to form the desired uniform glass fiber mat.
