摘要： In order to produce cellulose fibres, a solution of cellulose in a tertiary amino oxide is hot-shaped into filaments, the filaments are cooled and brought into a precipitation bath in order to precipitate the dissolved cellulose. Before being brought into the precipitation bath, the shaped solution is exposed for cooling to a substantially laminar gas current.

摘要： A process is disclosed for purifying a tertiary aminoxide aqueous solution that contains impurities that are in part dissolved and in part available in a non-dissolved, colloidal form. The process is characterised by the combination of the following steps: (A) the non-dissolved impurities in colloidal form are practically all removed from the aqueous solution; and (B) the aqueous solution obtained after step (A) is brought into contact with an ion exchanger.

摘要： The invention relates to a device for draining or storing viscous materials which are, for example, removed from a process as a result of exothermic events. According to the invention, said device comprises at least one unit (1, 2, 3, 4) which has an inlet (11, 21, 22, 31, 32, 41) for the viscous material and an outlet (10, 20, 41, 42) and which is at least partly filled with a non-flammable liquid which is inert in relation to the viscous material. Said unit can be configured in the shape of a pipe (1, 2, 3) or container (4). Preferably, several pipe-shaped units can be connected to each other or to a container-shaped unit (4). The drained solution can then be transported to the container (4) through the pipes (1, 2, 3).

摘要： The invention concerns a process for transporting a cellulose solution in an aqueous tertiary amine oxide through a component, the cellulose solution flowing in the component at a variable speed. The process is characterized in that, at a point at which the flow speed is comparatively low, the component has an aperture through which some of the cellulose solution flows out of the component.

摘要： The invention relates to a process for producing cellulose shaped bodies, said process comprising the following steps: (A) dissolving cellulose in an aqueous solution of a tertiary amino oxide, in particular N-methylmorpholine-N-oxide (NMMO), to form a cellulose solution which can be shaped; (B) shaping the cellulose solution and guiding the shaped cellulose solution into an aqueous precipitation bath in which the cellulose is precipitated, whereby a shaped body and a used precipitation bath are formed; (C) regenerating the used precipitation bath, a regenerated, aqueous amino oxide solution being formed which is used in step (A) again for dissolving cellulose. The invention is characterized in that in step (A) a regenerated, aqueous amino oxide solution is used which has a pH in a range whose upper and lower limits are defined, as a function of the tertiary amino oxide concentration, by the equation pH = - 0.0015 x A2 + 0.2816 x A + f, A being the tertiary amino oxide concentration in the aqueous solution, expressed in weight % of the aqueous solution, and satisfying the condition: 40 % ≤ A ≤ 86 %, and preferably ≤ 70 % A ≤ 80 %, and f having the value 1.00 for the upper limit and -1.80, and preferably -1.00, for the lower limit.
