    • A process for producing cellulosic shaped objects includes extruding and coagulating a solution of chemical wood pulp in a tertiary amine oxide, and possibly a liquid that does not dissolve wood pulp and is miscible with the tertiary amine oxide, the solution capable of being shaped into objects, the process of producing the shapeable solution employing a first wood pulp with a higher degree of polymerization and a second wood pulp with a lower degree of polymerization, and whereby initially a solution of the first wood pulp with a higher degree of polymerization in the tertiary amine oxide and possibly non-dissolving liquid, and a composition containing the second wood pulp with a lower degree of polymerization, tertiary amine oxide, and possibly non-dissolving liquid, are prepared separately, and the solution and composition are subsequently at least mixed to obtain the shapeable solution.
    • 用于生产纤维素形物体的方法包括将化学木浆的溶液挤出和凝结在叔胺氧化物中,并且可能的是不溶解木浆的液体,并且可与叔胺氧化物混溶,该溶液能够成形为物体 使用具有较高聚合度的第一木浆和具有较低聚合度的第二木浆生产可成形溶液的方法,并且由此最初在第三级中具有较高聚合度的第一木浆的溶液 氧化胺和可能不溶解的液体,并且分别制备含有聚合度较低的第二木浆,叔胺氧化物和可能不溶解的液体的组合物,然后将溶液和组合物至少混合 获得可塑的解决方案。
