    • The invention relates to a film tube (10) based on cellulose which is produced by extruding an aqueous cellulose-N-methyl-morpholine-N-oxide (NMMO) solution through a ring nozzle (21) onto a lining (3). The film tube (10) is manufactured by means of a vertically descending spinning in a spinning vat (12) in which a spinning bath (11) is located. The film tube (10) which is submerged in the spinning bath (11) passes through an air gap (9) between the underside of a nozzle block (7) and the upper surface of the spinning bath (11) and, internally, is pressurized, supported and slightly stretched in a transversal manner by compressed air. The film tube (10) is filled with an inner bath solution (31) via a supply tube (18). An idle roller (13) is situated near the bottom of the spinning vat (12) in order to guide the film tube (10) around and, afterwards, out of the spinning vat (12) in an upward sloping manner. The film tube is laid flat along a contact section (27) of the idle roller (13).
    • 本发明涉及一种基于纤维素的薄膜管(10),其通过将环形喷嘴(21)挤出纤维素-N-甲基吗啉-N-氧化物(NMMO)溶液到衬里(3)而制备。 薄膜管(10)通过在其中设置有纺丝浴(11)的纺丝槽(12)中通过垂直下降的纺丝制造。 浸没在纺丝浴(11)中的薄膜管(10)穿过喷嘴块(7)的下侧和纺丝浴(11)的上表面之间的气隙(9),内部是 通过压缩空气以横向加压,支撑和稍微拉伸。 膜管(10)通过供给管(18)填充有内浴溶液(31)。 空转辊(13)位于纺丝槽(12)的底部附近,以便以向上倾斜的方式将胶片管(10)引导到纺丝槽(12)周围。 薄膜管沿空转辊(13)的接触部分(27)平放。

    • A shaped article, especially a tubing, is disclosed which comprises a plasticized cellulose hydrate composition of high mechanical strength which is obtained by reacting a plasticized cellulose composition obtained by treating cellulose hydrate with a plasticity-enhancing amount of at least one plasticizing alkyl derivative which comprises an alkyl containing from about 8 to about 24 carbon atoms and which is selected from the group consisting of alkylamido-bis-dimethylene-triazinone-tetramethylol, alkylamino-bis-dimethylene-triazinone-tetramethylol, a substantially water insoluble ester of an aliphatic monocarboxylic acid containing from about 9 to about 25 carbon atoms, and a polyalcohol, such as glycerol or polyethylene glycol with a cyclic dimethylolurea derivative, and water and/or a plasticizer.Such shaped articles can be prepared by mixing a viscose solution with a liquid containing the plasticizing alkyl derivative, introducing the resulting mixture into a precipitating bath, washing the precipitated shaped body in the gel state, treating it with an acidic solution of the cyclic urea compound and drying it in the heat. Tube-shaped articles are especially suited as sausage casings.
