Abstract

The invention relates to a spinning device for the operation of the amine-oxide process under the wet/dry spinning process, consisting of: - a spinning nozzle with spinning holes for extruding the fibers; - a blower in which the extruded fibers are immediately cooled after being ejected from the spinning holes; - a container holding the liquid in the spinning bath; - a coagulation trajectory prepared in the liquid in the spinning bath for the coagulation of the extruded fibers; and - an air vent defined as the distance between the spinning nozzle and the surface of the liquid in the spinning bath. The characteristic is that the coagulation trajectory is fitted at a distance from the spinning nozzle such that the angle alpha formed on the fibers axially relative to the surface of the liquid in the spinning bath does not exceed 45°, and therefore the relationship 0,1 + 0.0051 ≤ 0.7.do.(h⁻¹)—h can occur where do is the distance (mm) between the spinning holes and the adjacent spinning holes on the spinning nozzle, and h is the distance (mm) of the coagulation trajectory. Clustered with the spinning nozzle, and I is the air vent (millimeters). 0.4 mm is less than or equal to do, less than or equal to 2 mm, and 0 mm is less than 1, less than 60 mm.

1. The spinning apparatus for the amine-oxide process of dry/wet spinning consists of: - a spinning nozzle with a spinning hole for extruding the fibers; - a blower in which the extruded fibers may be cooled after being ejected from the spinning hole; - a container holding the liquid in the spinning bath; - a coagulation trajectory prepared in the liquid in the spinning bath for the coagulation of the extruded fibers; and - an air vent defined as the distance of the spinning nozzle to the surface of the liquid in the spinning bath, where: - the coagulation trajectory (2) is fitted at a distance from the spinning nozzle (3) at an angle (alpha) in which the vertical fibers are formed at an angle (1a) to the surface (1a) of the liquid in the spinning bath less than 45°; and - where the relationship 0.1 + 0.0051 is less than or equal to 0.7. do (h-1) — h can be formed where do is the distance (mm) between the spinning hole and the spinning hole. Its adjacent to the said spinneret nozzle (3), h is the distance (mm) of the said spinneret trajectory (2) to the said spinneret nozzle (3), and l is the said air gap (mm). 0.4 mm is less than or equal to do, less than or equal to 2 mm, and 0 mm is less than 1, less than 60 mm. 2. The spinning device under claim 1 is of a unique nature in which the aggregation pathway (2) is designed by means of a deflection pathway (2) on the fibers (4;5) which not only aggregates but also deflects. 3. The spinning device under claim 2 is of a specific nature in which the deflection path (2) is designed so that no rotation occurs when the fibers are deflected (4;5). 4. The spinning equipment as per claims 1 to 3 is of a specific type in which the angle (alpha) does not exceed 20°. 5. The spinning apparatus for the operation of the amine-oxide process under the dry/wet spinning process consists of: - a spinning nozzle with a spinning hole for extruding the fibers; - a blower in which the extruded fibers are immediately cooled after being passed through the spinning hole; - a container holding the liquid in the spinning bath; - a deflection path provided in the liquid in the spinning bath for the agglomeration and deflection of the extruded fibers; and - air channels spaced at intervals between the spinning nozzle and the liquid in the spinning bath, the characteristic feature of which in the aforementioned deflection path (2) is designed so that it does not rotate when the fibers are deflected (4;5). 6. A spinning device as described in any of the claims 1 through 5, in which such spinning nozzle contains: - a uniformly rotating nozzle with its center for supplying the cooling gas; - a supply for the cellulose solution; - an annular spinning insert with spinning holes; and - a bombardment plate to deflect the cooling gas flow directly onto the extruded fibers from the spinning holes, so that the cooling gas stream needs to strike the fibers at the correct angle. 7. Any of the spinning devices under Claims 1 through 6 are of a specific nature in which the spinning fluid container is connected to a lifting device such that the container can be moved toward and toward the spinning nozzle in a vertical direction, thus the distance l is changed and such a clustering trajectory is arranged so that the distance h remains constant despite this movement.
