  • Patent number: 8303888
    Abstract: A process is disclosed of forming cellulose fibers. The process includes extruding an aqueous solution of cellulose and a solvent through a first member to form filaments. The first member has multiple rows of first and second openings with a nozzle positioned in each of the first openings. At least one of the nozzles in one row is staggered from at least one of the nozzles in an adjacent row. At least a portion of each of the filaments is shrouded in a pressurized gas emitted through each of the first openings. Each of the filaments is contacted with a liquid to remove some of the solvent and transform each of the filaments into a continuous solid fiber. The continuous solid fibers are then collected on a moving surface to form a non-woven cellulose web.

  • Patent number: 8029260
    Abstract: An apparatus is disclosed for extruding cellulose fibers. The apparatus includes a first member, a second member and a third member all secured together. Multiple nozzles extend outward from the first member and each is designed to direct an aqueous cellulose solution therethrough. As the aqueous solution is extruded, it is accentuated and accelerated by pressurized gas flowing through the first member and the second member and out through first openings formed in the third member. The pressurized gas at least partially surrounds each nozzle and shelters the molten filaments extruded therefrom. The third member also has multiple second openings formed therethrough which are also connected to a source of pressurized gas. The pressurized gas streams exiting each of the second openings function to keep each of the molten filaments from contacting an adjacent molten filament.

  • Patent number: 8029259
    Abstract: An array of nozzles is disclosed for forming multiple cellulose fibers. Each nozzle has a longitudinal central axis and includes a tube with a cross-section having a diameter through which an aqueous solution of cellulose and a solvent can be extruded into a molten filament. A first opening is present which surrounds each of the tubes. The first opening has a cross-section with a diameter, and each of the first openings is capable of emitting a pressurized gas which surrounds one of the extruded molten filaments. At least three second openings are spaced away from each of the first openings. Each of the second openings is capable of emitting a pressurized gas stream essentially parallel to the longitudinal central axis of each of the nozzles, and each of the pressurized gas streams functions to shroud one of the extruded molten filaments.
