A DEVICE FOR EXTRUDING SPINNING FILAMENTS FROM A SPINNING SOLUTION AND A LYOCELL METHOD BY WHICH SPINNING FILAMENTS ARE EXTRUDED

摘要

The invention relates to a device (1) for the extrusion of spinning filaments (9) from a spinning solution which contains water, cellulose and tertiary amino oxide, which is the case in said lyocell-method. Said device comprises a first spinning nozzle (6) which comprises a plurality of extrusion openings (8), A first spinning filament chamber (11) which is traversed by the spinning filaments (9) when in operation, connects itself directly to the first spinning nozzle in the opening direction of the extrusion opening. Also, at least one device (21), which is used to produce a forced flow of gas through the spinning filament chamber, is provided. According to the invention, a second spinning nozzle (7) comprising a second spinning filament chamber (12), which is arranged at a distance from the first, is provided adjacent to the first spinning nozzle in order to increase the packing density of the spinning nozzle. Also, the blowing device (21), which is used to produce a forced flow of gas also through the second spinning filament chamber (2), is arranged at least sectionally between the first and the second spinning filament chamber.
