Definitions
- the invention relates to a spinning bath tub according to the preamble of claim 1.
- a spinneret In pure wet spinning, there is a spinneret within a spin bath tub which is filled with a spin bath liquid (precipitation bath).
- the medium to be spun is fed by a pump via a pipe of the fully dipped into the spinning bath liquid spinneret and extruded through the spinneret orifices in the form of filaments directly into the spinning bath liquid.
- the filaments In the spin bath liquid, the filaments coagulate.
- DE-AS 1 102 338, DE-AS 1 112 604 and DE-PS 1 123 795 show spinneret arrangements that lie within a spin bath tub and are completely surrounded by spin bath liquid.
- the geometry of the spinning bath tub is such that the extruded filaments run essentially horizontally and are guided out of the spin bath tub only after being guided by deflection rollers over a distance determined by the necessary coagulation time and the spinning speed.
- the spinneret In dry / wet spinning, the spinneret is positioned above a spin bath liquid. Between the spinning nozzle openings having the underside of the spinneret and the surface of the spinning bath liquid is such an air gap.
- the medium to be spun is then first extruded in a non-precipitable medium - the air gap - and then passes into the precipitation bath, in which the coagulation takes place.
- the filaments run in this type of spinning vertically from top to bottom in the spinning bath and in this to a arranged inside the spin bath tub roller, which they are then directed obliquely upwards again led out of the Wanner. Again, the filaments have to travel a certain distance within the bath, so that the required coagulation sets.
- the invention is thus based on a spin bath tub consisting of a tub for receiving spin bath liquid, at least one roller arranged in the tub for deflecting the spun filaments, as well as an inlet and outlet system for spinning bath liquid.
- Object of the present invention is to improve a generic device.
- the geometry of the spinning bath tub allows an arrangement of a sense nozzle for both wet and dry / wet spinning.
- the spinning bath tub has the deflection rollers or receptacles for such rollers to be provided for carrying out the respective spinning process.
- the rollers are preferably rollers with an associated drive in the form of a watertight tubular drive.
- the geometric design of the Spinnbadwanne takes into account the fact that in the wet / dry spinning process, the filaments run a predetermined distance in the spinning bath and after a first deflection out of the Spinnbadwanne out. Accordingly, the Spinnbadwanne in one area to the required depth and is provided in this area with a receptacle for the deflection roller to be provided there.
- the spinning bath tub has at least one further receptacle for a deflecting roller, specifically above the tub or the liquid level. With this roller are in the wet / dry spinning process from the spinning bath liquid
- This rear roller is used both in the wet-dry spinning process as well as in the pure wet spinning process leading the filaments in the direction of the downstream processing stations.
- the spinning bath tub according to the invention has a front deep area, which serves the filament guide in the wet / dry spinning process. This area is not needed in pure wet spinning - here, the filaments run from a spinneret located in the front area of the Spinnbadwanne below the liquid surface substantially horizontally and first within the Spinnbadnetkeit to the rear guide roller, which deflects the filaments up for further processing.
- this bath area is provided with an intended molding area. piece, shaped body is filled. This reduces the amount of spinning bath liquid present in the tub, so it must also be circulated less liquid per unit time.
- the shaped body is removed and the entire depth is available in the front area of the bath. Since in the operating mode wet / dry spinning process, the rear, flat portion of the Spinnbadwanne is not needed, it can be provided to shut down another molding, through which then the rear Spinnbadwannen Scheme can be stopped.
- the spin bath has in the direction of the spun filaments a front first deep area and a subsequent shallower area.
- the spinning bath tub has in the first deep area on a guide roller for guiding the filaments generated during dry / wet spinning.
- the spinning bath tub has at least one guide roller, which serves the filament guide both dry / wet spinning and wet spinning.
- a shaped body which is used in the not required in the respective spinning process area of Spinnbadwanne
- the guide roller has its own drive.
- the drive is designed as a waterproof tubular motor.
- FIG. 1 shows a spinning bath trough SBW which has a greater depth in a front region B1 in the direction of the running filaments than in the rear region B2.
- the spinning bath tub SBW is filled with a spinning bath liquid SBF, which is controlled via indicated inlets and outlets ZL, AL in the level and the solvent concentration.
- a spinneret SD is arranged, specifically at a distance d from the surface of the spinning bath liquid SBF. The spinneret SD is acted upon by a pump, not shown, as well as a supply line with the solution to be spun.
- the filaments F emerging from the underside of the spinneret SD are extruded in air and, after the air gap d, enter the spinning bath liquid SBF, where the coagulation takes place.
- the filaments F run vertically down into the depth of the front portion B1 of the spinning bath tub SBW and are deflected at a lower deflecting roller UW1 to run obliquely upward from the Spinnbad sometimeskeit out to a second guide roller UW2, from which they to a third, in the rear area of the spin bath tub arranged deflection roller UW3 are passed.
- the filaments are guided to a downstream processing station, in the embodiment shown, the filaments F first run upwards, to then - to be forwarded horizontally - not shown.
- the spinning bath tub SBW has a depth in the front region B1, the design of which is adapted to the dry / wet spinning process to be carried out.
- the spinning bath tub SBW is made flat, the design is adapted here to the wet-spinning process to be carried out, in which the filaments F run substantially horizontally.
- the filament run in the wet spinning process is shown in FIG. 2.
- a spinneret SD is arranged below the surface of the spinning bath liquid SBF and is acted upon by a pump, not shown, and a feed line with the solution to be spun.
- the filaments F are extruded directly into the spinning bath liquid SBF and coagulate and travel upwardly at a flat upward angle to the third deflection roll UW3, from which they are directed upwards as in the previously described dry / wet spinning process and to another processing station, the washing baths become.
- the deflection rolls UW2 and UW3 are not required and, as they are waterproof, can remain in the required position during the dry / wet-spinning process.
- the dry flat / wet spinning process does not require the rear flat region B2 of the spinning bath tub.
- a molded body FKTN can be used, which displaces the spinning bath liquid in this area B2 and thus reduces the volume of the liquid required as well as to be circulated.
- FIG. 4 shows how the spinning bath tub SBW is used in a pure wet spinning process.
- a molded body FKN is used in the front deep region B1 of the spinning bath tub SBW, which part fills the part of the spinning bath tub SBW which is not required for wet spinning and thus reduces the takeup volume of the spin bath tub SBW.
