IP 2129 VISCOUS DISPERSION FOR FORMING WET-LAID, NON-WOVEN FABRICS Abstract of the Disclosure An improved process for forming a non-woven fabric by wet-laying, on paper making equipment, staple length, synthetic fibers having a length to diameter ratio of about 400 to 3000, and an improved, non-woven fabric produced by the process. The process involves forming a stable, viscous, uniform, air-fiber-water dispersion by: adding the fibers to a high-shear agitated mixture of water and a dispersant to separate the fibers and to com- pletely and uniformly distribute the individual fibers throughout the resulting, high-shear agitated, air, water and fiber mixture; and then slowly adding a thixotropic thickener to the high-shear agitated mixture to form the viscous, air-fiber-water dispersion, containing about 1% to 50% by volume of entrained air and having a nascent vis- cosity of about 10 to 125 cps., when measured at a shear rate of 30.5 sec.-1, and in which the individual fibers are restrained from becoming entangled and from forming knits, bundles, and strings.
