Definitions
- the invention relates to a device for carrying out a dry / wet spinning process.
- the technique of dry / wet spinning is very generally that spinning mass by a molding tool, e.g. a spinneret, in a medium which does not precipitate for the spinning mass, e.g. Air or an inert gas is extruded, wherein if a spinneret is used, filaments are formed which are stretched in this medium and then passed into a spinning bath liquid (coagulation bath) in which the filaments coagulate.
- a molding tool e.g. a spinneret
- a medium which does not precipitate for the spinning mass e.g. Air or an inert gas
- a method and a device for producing cellulosic fibers is known, according to which a solution of cellulose in a tertiary amine oxide is shaped in the warm state and the shaped solution is introduced into the precipitation bath through a gaseous medium (air) to precipitate the cellulose contained, the warm, shaped solution being cooled before being introduced into the precipitation bath.
- the cooling is carried out immediately after molding and preferably consists of blowing the cellulosic molding horizontally with air.
- the method according to the invention allows the cellulose solution to be spun with a high thread density without the spun threads sticking together after exiting the spinneret.
- DD-A-218 121 also relates to a dry / wet spinning process for producing cellulosic fibers from cellulose solutions in tertiary amine oxides. According to this method, too, the cellulose solution is spun in an air gap, that is the distance between the spinneret and the surface of the spinning bath liquid, and is drawn into an aqueous precipitation bath.
- DD-A-218 121 mentions that the air gap has no adverse consequences for the Spinning security can be shortened if a polyalkylene ether is added to the cellulose solution before spinning. A small air gap is advantageous because the risk of the freshly extruded filaments sticking together is reduced.
- EP-A-0 574 870 describes a dry / wet spinning process for processing solutions of cellulose in tertiary amine oxides and points out the advantage of a small air gap.
- this spinning process it is possible, according to the description in the description of this patent application, to spin with a small air gap and with a high number of spinning bores per unit area.
- the filaments should not stick together during spinning. It is recommended that the spun filaments come into contact with the spinning bath liquid in a spinning funnel. Spinning bath liquid is passed through this spinning funnel in cocurrent with the filaments.
- the axis of the spinning funnel is substantially perpendicular to the plane of the spinneret, and the flow of the spinning bath liquid is directed from top to bottom, the flow generally being caused by the free fall of the spinning bath liquid.
- the warping or stretching of the freshly extruded filaments is achieved in accordance with EP-A-0 574 870 in such a way that the filaments are essentially accelerated to their withdrawal speed by the spinning bath liquid flowing through the spinning funnel.
- This previously known spinning device has the disadvantage that the funnel tube of the spinning funnel, due to its relatively narrow diameter, places an upper limit on the filament bundle to be carried out with regard to its overall cross section, which is additionally set unsatisfactorily low for large-scale implementation of the method. According to the experience of the applicant, this is the case with a diameter of 6 mm, as exemplified in EP-A-0 574 870, is only possible to pass a bundle of filaments consisting of a maximum of 100 filaments through the funnel, since spinning bath liquid must also be transported through the funnel. This in turn means that when using such a spinning funnel, only one spinneret with a maximum of 100 spinning holes can be used.
- the funnel tube must be correspondingly larger, which in turn means that much more spinning bath liquid flows off and has to be circulated. This high throughput of spin bath liquid leads to turbulent flows in the spin bath, which disrupts the dry / wet spinning process.
- GB-A-1,017,855 describes a device for dry / wet spinning of synthetic polymers.
- the use of a spinning funnel is recommended, through which spinning bath liquid is allowed to flow in cocurrent with the extruded fibers.
- the spinneret is about 0.5 cm above the surface of the spin bath.
- the object of the invention is to provide a container for holding spinning bath liquid, which makes it possible to carry out a dry / wet spinning process with high spinning safety without using a spinning funnel, and at the same time:
- the device according to the invention is intended to allow spinnerets of various sizes to be used without the device having to be converted, ie that the device can be easily adapted to the spinneret used in each case.
- the container according to the invention for holding spinning bath liquid for carrying out a dry / wet spinning process, in which process a spinning mass is extruded through a spinneret with a high spinning hole density into a gaseous medium, a family of filaments being formed which is distorted by the gaseous medium are introduced into the spinning bath liquid, characterized in that a deflection member for bundling and deflecting the filaments is provided in the container, which can be pivoted in the vertical plane.
- the filament sheet is therefore not bundled by a spinning funnel, as described in EP-A - 0 574 870, but by a deflecting member.
- the angle of warpage is the angle that the outermost filament or edge filament of a filament array leaving the spinneret forms with the perpendicular to the plane of the spinneret.
- a preferred embodiment of the container according to the invention is that the deflecting member has a substantially cylindrical body which is delimited by two substantially annular flanks, the planes formed by the flanks preferably forming an angle with one another of between 1 ° and 30 °. This embodiment is particularly advantageous for the start of spinning, as will be explained below.
- the container according to the invention is particularly suitable for dry / wet spinning formable solutions of cellulose in an aqueous tertiary amine oxide.
- the invention further relates to a method for dry / wet spinning by extrusion of a spinning mass through a spinneret with a high spinning hole diameter into a gaseous medium, a family of filaments being formed which are introduced into a spinning bath liquid with delay by the gaseous medium, bundled and over one Guide element are guided, which is characterized in that the guide element is at such a distance from the spinneret that the angle between the outermost filaments of the filament array and the perpendicular to the spinneret does not exceed 20 °.
- the spinning bath liquid is not conducted in cocurrent with the filaments, and the delay is therefore not carried out with the kinetic energy of the spinning bath liquid. o created as detailed below.
- a moldable solution of cellulose in an aqueous tertiary amine oxide is preferably used as the dope.
- FIG. 1 shows a general illustration of the dry / wet spinning process
- FIG. 2 schematically shows a perspective illustration of an embodiment of the container according to the invention
- FIG. 3 shows that shown in FIG Deflector shows.
- 1 denotes a container for holding spinning bath liquid, the surface of the spinning bath liquid being indicated by la.
- spinning mass is extruded through the spinneret 7 and the extruded filaments are drawn off via the air gap LS into the spinning bath liquid in which they coagulate.
- the coagulated filaments are deflected at the deflecting member 2 and drawn off obliquely upwards.
- the distance of the underside of the spinneret 7 from the surface la of the spinning bath liquid is defined as the air gap LS.
- the draft angle defined above is denoted by ⁇ .
- the reference numeral 1 ' denotes a trough-shaped container for holding spinning bath liquid.
- the spinning bath liquid is fed in via line 3 at the lower end of the container 1 'and flows upwards. If the container is filled, spinning bath liquid passes over the overflow edge 5 into the drain collecting cup 6, as a result of which a constantly high liquid level in the container 1 'is maintained.
- the spinning bath liquid that has overflowed into the drain collecting cup 6 speed is discharged via the discharge line 4 and fed back to the container 1 'according to the invention via the line 3 via an external pump system (not shown).
- the discharge line 4 is expediently provided with a sieve in order to filter off any filament residues that may occur.
- a baffle plate 10 is provided in the container 1 'and is fastened parallel to the wall of the container (not shown).
- Reference number 7 denotes a spinneret, the emerging filaments being indicated by dashed lines.
- Reference number 2 ' denotes a deflection element, via which the filament sheet is bundled and drawn off obliquely upwards (not shown).
- the deflection element 2 ' is attached to a rotatable axis 9 via an arm 8.
- the axis 9 is laterally installed in the wall of the container 1 'and is naturally sealed so that no spin bath liquid can escape.
- the deflection element 2 ' can be pivoted in the container. This turning can be accomplished, for example, by means of an electric motor 11.
- FIG. 2 shows the lower end position of the deflection element 2 ', in which the distance from the surface of the spinning bath liquid is greatest.
- the upper end position of the deflecting member 2 ' in which the distance to the surface of the spinning bath liquid is the smallest, is shown in broken lines.
- the maximum angle is pivoted around which the deflection member 65 ".
- the container 1 ' is expediently equipped with a lifting device (not shown) with which the height of the container 1' and thus the width of the air gap LS, that is the distance from the surface of the spin bath liquid to the stationary spinneret 7 ', can be adjusted.
- the container according to the invention allows the draft angle ⁇ to be kept as small as possible regardless of the width of the spinneret 7 '. If a wide spinneret is used, as shown in FIG. 2, the draft angle ⁇ can be reduced by moving the arm 8 downwards and the spinning security can thus be increased. If the spinnerets are less wide, the deflection element 2 'can be positioned closer to the surface of the spinning bath liquid.
- Another advantage of the container according to the invention is that the start of spinning can be carried out more easily.
- the deflection element is brought into the upper end position and the air gap LS is enlarged by moving the entire container downwards.
- the filaments emerging from the spinneret 7 'are immersed in the spinning bath which is relatively distant, are guided over the deflecting element 2' and are bundled and held on the deflecting element by the inclined flanks 2'b and 2'c (see FIG. 3).
- the bundling is facilitated if the deflecting member is set in the upper end position so that the area with the larger flank spacing faces the spinneret 7 '.
- the bundle of filaments is pulled off diagonally upwards.
- the deflection element 2 ' can be lowered immediately into the spinning bath by rotating the axis 9, as a result of which the draft angle is reduced and, at the same time, the bundling of the filament sheet is somewhat increased due to the inclined flanks, since the deflection element 2' is caused by the rotation Spinneret 7 'now turns to an area which has a smaller flank spacing, whereby the bundling is increased.
- the deflected filament bundle is a downstream take-off device (not shown) and set the desired titer by warping in the air gap LS by selecting a certain withdrawal speed.
