A method is provided for forming a wet-laid nonwoven glass fiber mat comprised of a plurality of bundles of fibers. The method includes the steps of adding chopped fibers to a water slurry containing a sufficient amount of a suitable hydrophobic agent to cause the fibers to form a plurality of bundles. The fibers are then formed into a mat which may be used in a number of reinforcement applications. A method is also provided for modifying the components in the water slurry to produce mats comprising either bundles of fibers or dispersed fibers.

[ What is claimed is:] [1.] In a method for forming a wet-laid glass fiber mat which includes the steps of adding wet-chopped glass fibers to an aqueous mixture containing a surfactant and a viscosity modifier, thereby forming a slurry, agitating the fibers to cause them to disperse, removing water from said fibers to form a web, and applying a binder to said web to form said glass fiber mat, the improvement comprising the step of adding a sufficient amount of a suitable hydrophobic agent, having an HLB value of from about 1 to about 15, to said slurry to cause said chopped fibers to form bundles in said slurry.
