Abstract: A filter composite comprises a first layer of glass fibers having random orientation, and synthetic resinous fibers extending in close association with the glass fibers, the glass fibers having: i) diameters between 1 and 16 microns ii) lengths between about ¼ and 1½ inches the synthetic fibers having denier between 1.6 and 40, and length between ¼ and 2 inches.

Abstract: A machine and method of forming fiberglass mats. Chopped glass fibers are mixed with water in a slurry and a movable screen is passed, generally upwardly, through a slurry. As the screen is moved, its surface is uniformly coated with the glass fibers in a uniformly increasing depth, dependent upon the length of travel of the screen through the slurry. Longitudinally oriented and randomly oriented continuous strands are projected onto the fibers captured on the screen at different locations in order to provide the resultant mat with tear strength in all directions. The screen passes over a vacuum for removal of most of the water from the workpiece; subsequently, a binder is added to the workpiece and the continuous mat is passed through an oven for curing of the binder. The mat is then wound upon a spool for later transport to a location in which the mat can be processed into a final product.
