Title: Improvements in or relating to the preparation of viscose
IPC: D01F2/08
Filed: 1945-07-02
Abstract: In the production of viscose, the alkali cellulose is placed in a vacuum xanthate kneader and the stages of xanthation and dissolution are divided into several sub-stages in each of which the speed of the mixing arms is adjusted to the most appropriate value for the operation which is to be performed.  Variable or continuous change-speed gear, hydraulic gearing, or bi- or poly-polar motors, may be employed.  The process may be divided into the following steps, all carried out in the same apparatus: preliminary cooling of the alkali-cellulose, admission of carbon bisulphide and water, xanthation reaction, impasting the cellulose xanthate with strong caustic soda solution, diluting with dilute caustic soda or with water.  In an example, matured alkali cellulose is placed in the xanthate kneader and cooled to 22-24 DEG  C. for an hour.  Carbon bisulphide is then added during a period of 15 minutes.  Water is added, and the xanthation is allowed to proceed, this reaction taking about an hour.  Impasting with strong caustic soda takes another hour, and dilution takes a further 55 minutes.  During the first stage of the process, the mixing arms are rotated at 18 r.p.m. and the grinding arms at 12 r.p.m.  During xanthation, the speeds are 9 and 6 r.p.m.  During the impasting they are 20 and 13 r.p.m., and during dilution they are 30 and 20 r.p.m.  Specifications 234,039, 273,280, [both in Class 2 (ii)], and 350,397 are referred to.
