Definitions
- the invention relates to a wetting device for installation in a spinning system for producing spun threads from a spinning solution containing water, cellulose and tertiary amine oxide, with a feed line for a treatment medium and a spinning system with such a wetting device.
- the spinning solution is passed through a field of extrusion openings and thereby extruded to the spun threads.
- a gas path usually in the form of an air gap, in which the freshly extruded filaments are drawn, which leads to an alignment of the molecules and a consolidation of the filaments as well as to a desired thread diameter.
- the filaments in the air gap are blown with a gas to cool and solidify their surface, thus reducing the surface stickiness. Due to the reduced surface stickiness, the spun threads no longer tend to clump and the error rate of the spinning process is reduced. The spinning security increases accordingly.
- the extruded spinning solution - already in the form of spun threads - is passed through a treatment medium which precipitates the cellulose, such as water. Under the influence of the treatment medium, the filaments coagulate and harden.
- the treatment medium is received in a spinning bath container through which the spun threads are passed.
- a spinning bath container through which the spun threads are passed.
- Such devices are known for example from WO 96/20300 and DE 100 37 923. If the extrusion openings are arranged on a circular surface or a circular surface, the spin bath containers can also be designed as funnels. be designed as in the devices of WO 94/28218, DE 44 09609 and WO 01/68958.
- the spinning bath containers used in the prior art lead to spinning plants which are easy to handle in terms of process technology, but they decisively limit the economy of the process, which essentially depends on the extrusion speed of the spinning solution and the transport speed of the spinning threads through the treatment medium as well as the spinning density. H. the number of extrusion openings per unit area.
- the problem with the conventional spinning bath containers is, above all, the immersion process of the spun threads in the treatment medium: with increasing spinning speed, turbulence and currents increasingly arise due to the treatment medium entrained with the spinning threads. These lead to a churned surface and thus to a mechanical strain on the filaments when immersed. If the mechanical load is too high, the spun threads can break, which leads to an interruption of the entire manufacturing process.
- the filaments are passed through a funnel which is filled with a treatment medium.
- the spun threads appear through an outlet opening, with part of the treatment medium inevitably flowing out.
- the spinning performance of the spinning funnel systems is also subject to narrow limits: in order to make the spinning process more economical, the number of spinning threads passed through the spinning funnel must be increased. The consequence of this is that the spinning funnel has to be lengthened and the outlet opening has to be enlarged. Due to the elongated spinning funnel, the static pressure in the treatment medium at the outlet opening increases, which leads to high outflow velocities at the outlet opening.
- the spun threads are passed through a film of treatment medium which runs down an inclined surface of a spinning bath container designed as an overflow container.
- an overflow container generates a kind of waterfall from the treatment medium through which the filaments are passed.
- the invention is therefore based on the object of improving the known spinning systems in such a way that the economy of the process is increased by increasing the spinning speed and reducing the need for treatment medium while at the same time improving the control of the precipitation process.
- This object is achieved for a wetting device described at the outset by a wetting area arranged in the installed state of the wetting device between the spinning threads and the feed line on a guide wall and permeable to the treatment medium at least in sections, along which the spinning threads can be guided in the installed state and through which the spinning threads pass the treatment medium are wettable.
- the wetting device according to the invention can also be used as a retrofit kit for existing spinning systems.
- the solution according to the invention consequently consists in guiding the wetting medium through the guide wall to the spun threads.
- This solution which is quite simple in itself, surprisingly results not only in good wetting of the spinning threads with the treatment medium, but also in a considerably reduced friction between the spinning threads and the guide wall compared to the known wetting devices, since the treatment medium is pressed between the spinning threads and the guide wall and forms a friction-reducing sliding layer between the filaments and the guide wall.
- This sliding layer reduces the mechanical stress on the spinning threads and the susceptibility to errors of the spinning process. Due to the reduced friction, the transport speed of the spun threads can be increased without impairing the spinning safety.
- the guide wall can form micro pockets, at least in the wetting area, on which the treatment medium entrained with the spun threads can be stowed during operation between the spun threads and the wetting area, so that the sliding layer becomes thicker.
- These micro pockets can be designed in the form of longitudinal grooves which extend transversely to the transport speed of the spinning threads, or in the form of regularly or irregularly arranged depressions, similar to the surface of a golf ball.
- a mesh or grid-like surface structure also facilitates the formation of a sliding layer.
- the supply of the treatment medium to the wetting area is structurally simple, in particular, if the guide wall is formed on an essentially hollow cylindrical body through which the treatment medium can feed the wetting area during operation.
- the guide wall is therefore part of the supply line for the treatment medium.
- the hollow cylindrical body can be configured essentially in the form of a roller.
- the wetting device can have at least one bearing, by means of which the body forming the guide wall can be rotatably attached to the spinning system. This configuration can be achieved that the guide wall rotates with the filaments, so that the friction between the filaments and the guide wall is reduced again.
- the guide wall is formed along an essentially rotationally symmetrical body.
- the areas permeable to the treatment medium can extend over the entire circumference or can be divided into individual areas spaced apart in the circumferential direction.
- the wetting device can have a means of rotation by which the rotational movement of the guide wall can be influenced.
- a means of rotation can be, for example, a motor, for example an electric motor, or a brake.
- the guide wall can be driven in the direction of the spun threads or counter to the direction of the spun threads by a motor, so that the wetting device additionally serves as a stretching means by which a tensile force into the spun threads upstream - for example when the guide wall rotates at a greater speed than that Transport speed of the spun threads - or downstream - for example when rotating at a speed lower or opposite to the transport speed of the spun threads - can be introduced into the spun threads.
- Porous materials can be considered as materials for the guide wall, which in further developments are also made up of several layers of materials of different porosity.
- Such porous materials can be sintered materials or materials made up of woven or knitted fabrics or nonwovens.
- the wetting device according to the invention can also be used at the same time as a deflection element, by means of which the direction of transport of the spun threads is changed.
- the wetting surface can be curved, in particular in the transport direction of the spun threads.
- a plurality of wetting devices at least two, can also be designed one behind the other in the transport direction of the spinning threads.
- the wetting devices connected in series can also be supplied in series with the treatment medium.
- wetting device When the wetting device is used simultaneously as a stretching or removal means, in particular a plurality of wetting devices with rotatably mounted bodies that form the guide wall can be arranged one behind the other. In this way, not only a multi-stage precipitation, but also a multi-stage drawing can be achieved.
- a wetting device with a rotatably mounted body and a wetting device with a fixed guide wall can alternate.
- the tension in the spun threads and thus the degree of stretching is generated by the rotational speed of the rotatably mounted body and by the frictional resistance of the spun threads on the stationary guide wall.
- the mechanical properties of the spun threads can be decisively improved in comparison to conventional wetting devices without the spinning speed having to be reduced and the economy of the production of the spun threads thereby suffering.
- the wetting device according to the invention which can be used instead of a spinning bath container, is more versatile and can simultaneously serve as a deflecting member and / or extension means. The advantages according to the invention are also achieved by appropriate process control.
- Figure 1 is a schematic representation of a spinning system with an embodiment of a wetting device according to the invention.
- FIG. 6A and 6B are schematic detailed representations of section VI of FIG. 5 of two further embodiments of the wetting device according to the invention.
- FIG. 7A and 7B are schematic detailed representations of section VII of FIG. 6A of two further embodiments of the wetting device according to the invention.
- FIG. 8 shows a schematic illustration of a spinning system of a further embodiment of a wetting device according to the invention.
- 9 to 11 are schematic representations of possible process procedures using the wetting device according to the invention.
- the spinning threads 6 are produced by the spinning plant 1 in FIG. 1 according to the Lyocell process from a spinning solution containing water, cellulose and tertiary amine oxide.
- the three process steps typical of the Lyocell process are carried out by the spinning plant 1, namely the extrusion of the spinning solution 5 into spun threads 6, the subsequent stretching of the extruded spun threads 6 in a gas section 7 and the wetting of the drawn spun threads 6 with a treatment medium, such as Water to precipitate and solidify the filaments.
- a treatment medium such as Water
- the hiding of the spun threads 6 in the gas path 7 can be carried out in a non-mechanical manner, for example by air flowing axially around the spinning threads, the speed of which is greater than the transport speed T of the spinning threads 6, or in a mechanical manner by a take-off mechanism 10, through which the spinning threads 6 are drawn off become.
- the take-off mechanism 10 can have motor-driven rollers.
- the spinning threads 6 can be blown in the gas section 7 essentially transversely to the transport direction T of the spinning threads.
- a blowing device 11 is used, which directs a preferably turbulent gas flow onto the filaments 6.
- the stretched spun threads 6 can be wetted with treatment fluid 8 by a wetting device 9 according to the invention, in which a guide wall 12 between a feed line 13, through which the treatment medium 8 is fed to the wetting device 9, and the spun threads 6 is arranged.
- a wetting area 14 is provided, which is shown in FIG.
- the wetting area 14 is at least in sections for the treatment medium. casual, so that the treatment medium 8 brought in through the feed line 13 emerges in the wetting area 14 from the guide wall 12 and wets the spun threads 6 guided along the guide wall.
- the treatment medium 8 is pressed out of the spinning threads 8 by the take-off mechanism 10, so that it drips or flows into a collecting device 15.
- the treatment medium 8 is fed from the collecting device 15 via leads 16 to reprocessing steps, which are not shown in FIG. 1. After reprocessing, the used treatment medium 8 can be fed back to the wetting device 9.
- a wetting device 9 according to the invention shown by way of example in FIG. 1 is used instead of the spinning bath container and completely replaces it.
- the spun threads 6 lie against the guide wall 12 in the wetting area 14, a sliding film of treatment medium 8 preferably being located between the spinning threads and the wetting area 14.
- FIGS. 2 to 5 Further embodiments of the body comprising the guide wall 12 are described with reference to FIGS. 2 to 5.
- the embodiments of Figures 2 to 5 are shown in a cross section along the plane E of FIG. 1.
- the guide wall 12, which forms the wetting region 14 is designed as an essentially flat or / and as a wall that curves slightly perpendicular to the plane of the drawing. A deflection of the transport direction T of the spun threads 6 therefore takes place in the wetting devices 9 of FIGS. 2 and 3 by means of a deflecting element 17 arranged below or by the take-off mechanism 10 known from FIG. 10.
- the body 18 forming the guide wall 12 is designed as an open channel filled with treatment fluid. Only through the static pressure of the treatment medium 8 is it pressed through a region 19 of the wetting region 14 which is permeable to the treatment medium onto the side of the spun threads 6, where these are wetted by the treatment medium.
- the area 19 can comprise the entire wetting area 14 or only parts thereof.
- the body 18 of the wetting device 9 is designed essentially as a hollow cylinder, the treatment medium 8 being conducted inside the hollow cylindrical body 18.
- the treatment medium 8 can be pressurized, so that an amount of treatment medium 8 that can be controlled via the pressure is pressed through the porous region of the wetting region 14.
- the entire wetting region 14 is designed to be permeable to the treatment medium. Since the guide wall 12 in the transport direction T of the spun threads is also substantially straight in the embodiment of FIG. 3, the spun threads must be deflected by a downstream deflecting member 17 or a downstream take-off mechanism 10.
- a downstream deflection element 17 can be dispensed with if the guide wall 12 is curved in the transport direction T of the spun threads 6. Depending on the curvature and length of the guide wall 12, any deflection angle ⁇ can be achieved. The deflection angle ⁇ essentially results from the degree of wrap of the body 18 through the spun threads 6.
- the straight guide wall 12 according to the embodiment of FIG. 3 is replaced by a guide wall 12 curved in the transport direction T.
- a plurality of separate areas 19 that are permeable to the treatment medium are provided in the wetting area 14, preferably at the points at which a high contact pressure of the spun threads against the guide wall 12 due to the deflection of the spun threads 6 by the deflection angle ⁇ prevails. Due to the treatment medium escaping under pressure in these areas, strong friction between the spun threads 6 and the guide wall 12 is avoided in these critical areas in this embodiment.
- a further embodiment of a wetting device 9 according to the invention, which additionally additionally serves as a deflection member, is shown in FIG. 5.
- the body 18 of this embodiment is also hollow cylindrical, in particular in the form of a tube with a wall permeable to the treatment medium at least in the wetting region 14.
- Treatment medium 8 is applied to the interior of tubular body 18. In this embodiment, the treatment medium emerges over the entire circumference of the body 18.
- the double function as a wetting device and as a deflecting device simplifies the process control and the construction of spinning systems considerably.
- Compared to conventional deflection devices there is the advantage that, due to the treatment medium passed through the guide wall 12, it accumulates between the spun threads and the guide wall 12 or is pressed into this area, so that a sliding layer is formed which reduces the friction of the spun threads. Because of the reduced friction, the deflection of the spun threads according to the invention can take place at an earlier point in time compared to the prior art after the extrusion of the spinning solution, at which the spun threads are not completely coagulated. Larger deflection angles ⁇ can also be achieved.
- FIG. 6A shows the detail VI of FIG. 5 on an enlarged scale.
- the pressurized treatment medium 8 is pressed along the arrows 21 through the areas 18 of the guide wall 12 which are permeable to the treatment medium and into the wetting area 14 between the spun threads 6 and the guide wall 12. Since the spun threads are transported past the guide wall 12 as a dense, flat curtain, they offer great resistance to flow through the treatment medium. Consequently, only a small part of the treatment medium 8 passes through the spun threads 6, the larger part of the spun threads is entrained with the spun threads 6 to form the sliding layer 20.
- the guide wall 12 can also have a multilayer structure.
- the area 19 permeable to the treatment medium can be constructed from a plurality of permeable layers 19 ', 19 ", 19'", .... These individual layers can be constructed differently, for example once as a woven or knitted layer, sometimes as a non-woven layer, and can be provided with different permeabilities. Different sintered layers or a one-piece construction from a sintered guide wall 12 are also possible.
- the formation of the sliding layer 20 can be facilitated by various measures. Examples of such measures are shown in FIGS. 7A and 7B, in which section VII of FIG. 6A is shown enlarged.
- the formation of a sliding layer 20 is facilitated by the fact that the guide wall 12 forms micro pockets 22 in the wetting area, on which the treatment medium 8 entrained by the transport movement T of the spun threads 6 is shown in the areas 23 shown with hatching builds up and thus presses the spun threads deflected as a curtain away from the surface of the guide wall 12.
- Areas in which the surface increases in relation to the surroundings in the direction of transport T are referred to as micro pockets, so that a kind of depression or “pocket” is created in front of this raised area. The pressure in the treatment medium increases at these pockets due to the build-up.
- the micro pockets can be arranged randomly or regularly distributed on the surface of the guide wall 12 and can have heights of the micro pockets between 20 and 150 ⁇ m.
- the micro pockets 22 can also be formed by a net-like surface structure or, as shown in FIG. 7B, by longitudinal grooves which extend essentially transversely to the transport direction T of the spun threads 6.
- FIG. 8 shows a schematic illustration similar to the illustration in FIG. 1, although the wetting device 9 has an essentially roller-shaped or tubular body 18, which also serves as a deflection element 10.
- the body 18 is rotatably held on the spinning system 1 by means of schematically illustrated bearings 24, so that the guide wall 12 can have a rotational speed. If the body 18 can rotate freely, the rotatable bearing can again minimize the friction.
- the body 18 of the embodiment of FIG. 8 can be influenced in its rotation by an optional drive means 25, for example, it can be braked or accelerated in relation to the transport speed of the spinning threads. In this way, a tensile force can be introduced into the spun threads 6 in the area upstream or downstream of the wetting device 9 via the drive means 25.
- the wetting device 9 can also be used as a drafting means in a double function.
- the guide wall 12 in the wetting area 14 is provided with sections 19 which are spaced apart from one another in the circumferential direction and extend axially over the wetting area 14 and which are permeable to the treatment medium 8.

- FIG. 9 shows a spinning installation 1 in which a wetting device 9 according to the invention is driven to rotate in the direction indicated by arrow 26.
- the wetting device 9 serves both for wetting the spun threads and for stretching the spun threads in the gas section 7 immediately after the extrusion.
- the spun threads 6 are deflected by the wetting device 9.
- the spun threads 6 are kept largely free of tension in a region 28 for through-coagulation by a roller unit 27 rotating counter to the transport direction T of the spun threads 6.

- a further wetting device 9 according to the invention is arranged in the region 29, which passively rotates with the spinning threads 6 or is rotatably driven in the direction thereof.
