    • The invention concerns a process for manufacturing cellulose moulded bodies in which a suspension of cellulose in an aqueous solution of a tertiary amine oxide is converted to a mouldable solution which is extruded using a shaping tool and introduced into a regeneration bath. The process is characterised by the fact that at least a portion of the materials in the apparatus and pipes used for transporting and processing the solution and in contact with the mouldable solution contains at least one element from the group titanium, zirconium, chromium and nickel in elemental form or in the form of compounds, to a depth of at least 0.5 mu m, preferably more than 1.0 mu m, and in a proportion of at least 90 %; the rest of the composition must not contain any of the elements copper, molybdenum, tungsten or cobalt. By using specific elements and compounds in this way, it is possible to prevent or limit exothermic decomposition reactions in the cellulose solution.
    • 本发明涉及一种用于制备纤维素的成型体,其中,在叔胺氧化物的水溶液中的悬浮液的纤维素被转化成其通过成形工具挤压,并进行到沉淀浴中的可模制溶液的方法。 该方法的特征在于,在设备和管道系统的材料的至少一部分为所述溶液的运输和处理,以至少0.54克的深度(米)m是与所述可模制的溶液,优选地大于1微米的接触 M包括至少至少90%的单质形式选自钛,锆,铬和镍中选择的和/或在化合物形式的元素,与剩余的组合物不含有的元素铜,钼,钨或钴的条件 , 通过本发明的用途的某些元素和化合物的放热分解反应的出现和程度可以忽略保持在纤维素溶液。
