ABSTRACT:
The spinneret according to the invention is especially suitable for spinning cellulose solutions and has a die body which is essentially rotationally symmetrical having an inlet in its centre for cooling gas, an inlet for cellulose solutions, an annular deep-drawn spinning insert of precious metal with spinning holes wherein the spinning insert is designed pan-shaped in cross-section, and a baffle plate to deflect the cooling gas stream through the cellulose filaments which are extruded from the spinning holes, so that the cooling gas stream strikes the extruded cellulose filaments essentially at right angles. The spinning holes in the spinning insert are uniformly spaced from one another.
