Abstract APPARATUS FOR PRODUCING SYMMETRICAL FLUID ENTANGLED NON-WOVEN FABRICS AND RELATED METHOD An apparatus and related process for entangling a stable fibrous web which employs divergent fluid jets. The web is advanced through an entangling station on a conveying means which supports an entangling member having a symmetrical pattern of fluid pervious void areas. The divergent jet sprays which are disposed above the entangling member direct a continuous curtain of fluid onto the web, coacting with the entangling member to entangle web fibers into a coherent lattice structure. The divergent jet sprays are provided by nozzles having wide orifice diameters which accommodate less complex fluid recirculation and filtration systems than employed in prior art columnar jet processes.
