    • 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.
    • 公开了用于挤出纤维素纤维的装置。 该装置包括一个固定在一起的第一构件,第二构件和第三构件。 多个喷嘴从第一构件向外延伸,并且每个喷嘴被设计成引导纤维素水溶液通过其中。 当水溶液挤出时,通过流过第一构件和第二构件的加压气体并且通过形成在第三构件中的第一开口从外部挤压出来。 加压气体至少部分地围绕每个喷嘴并遮住从其挤出的熔融长丝。 第三构件还具有穿过其形成的多个第二开口,其也连接到加压气体源。 离开每个第二开口的加压气流用于保持每个熔融长丝不接触相邻的熔融长丝。
