摘要： The present invention relates to a buffer tank as is substantially used for ensuring a constant supply of the spinning machine with a polymer melt in spinning machines. To this end the buffer tank is provided with a compensation chamber whose volume is variable in response to a pressure prevailing in the polymer melt and to a volume flow variation. The polymer melt flows from a polymer melt entry opening to a polymer melt exit opening through the compensation chamber. It is the object of the present invention to make the flow through the compensation chamber uniform. The residence time of the polymer melt in the compensation chamber shall thereby be prevented from having a wide range, the latter resulting in an irregular quality of the yarns produced by the spinning machine because of the time-dependent, mechanical and chemical properties of the polymer melt. To achieve said object, the compensation chamber is provided for flow optimization with at least to one flow guiding element projecting into the flow of the polymer melt, which is smaller than the flow cross-section of the compensation chamber and by which the velocity profile in the direction of flow through the compensation chamber is made uniform at least in sections.

摘要： The invention relates to a method and a device (1) for the production of a cellulose solution, from which endless moulded bodies (2) can be extruded. First, a cellulose suspension is produced from cellulose (3, 4) and water (6) in a pulper (5). The cellulose suspension is then expressed by a press device (10). After expressing, a tertiary amine oxide, in particular N-methylmorpholine-N-oxide, is fed as a solvent to the cellulose suspension, thus producing a cellulose solution. The efficiency of the method and the device and their environmental compatibility can be improved in that the press water (11) expressed by the press device (10) is at least in part fed back to the pulper (5). In a further development the proportion of the press water (15) in the water (6) is varied depending on the metal content of the cellulose (3, 4) and/or of the cellulose solution.

摘要： The invention relates to a method and a device for producing Lyocell fibers, which are extruded from a spinning mass containing water, cellulose and tertiary amine oxide. The spinning mass is obtained from cellulose in a number of process steps, wherein a treatment medium is added to the cellulose, cellulose suspension and/or cellulose solution. In order to be able to implement a stable and environmentally compatible spinning method irrespective of the type of cellulose used, according to the invention, provision is made that the content of at least one type of metal ion destabilising the cellulose suspension and/or cellulose solution is monitored in the cellulose, cellulose suspension and/or cellulose solution and adjusted below a stability limit. With the device according to the invention, the metal ion content is measured via sensors (23, 23′) and the metal ion content is adjusted using a control device (17).
