Definitions

  • the invention relates to a wetting device for installation in a spinning plant for the production of spun yarns, for example for spun yarns from a spinning solution containing water, cellulose and tertiary amine oxide, with a supply line for a treatment medium, with a built-in state between the spun yarns and the supply line to a Guide wall arranged for the treatment medium at least partially permeable wetting area along which the filaments in the installed state feasible and through which the filaments are wetted with the treatment medium
  • the spinning solution is passed through a field of extrusion orifices and extruded into the filaments.
  • a gas line usually in the form of an air gap, in which the freshly extruded filaments are drawn, which leads to alignment of the molecules and solidification of the filaments and to a desired filament diameter.
  • the filaments in the air gap are blown with a gas to cool and solidify their surface to reduce surface tackiness. Due to the reduced surface tackiness, the spun yarns no longer tend to form clumps and the susceptibility to failure of the spinning process is reduced. Accordingly, the spinning security increases.
  • the extruded spinning solution - already in the form of filaments - passed through a cellulose precipitating treatment medium such as water. Under the action of the treatment medium, the filaments coagulate and harden.
  • the treatment medium is accommodated in a spinning bath container through which the spun yarns pass be directed.
  • a spinning bath container through which the spun yarns pass be directed.
  • Such devices are for example from the WO 96/20300 and the DE 100 37 923 known. If the extrusion openings are arranged on a circular ring surface or a circular surface, then the spin bath containers can also be used as funnels be designed as the devices of the WO 94/28218 , of the DE 44 09 609 and the WO 01/68958 ,
  • the filaments are passed through a funnel filled with a treatment medium.
  • the filaments come through an outlet opening, wherein inevitably a part of the treatment medium flows out with.
  • the spinning performance is also narrow limits: To make the spinning process more economical, the number of spun yarns passed through the spinning funnel must be increased. This has the consequence that the spinning funnel extended and the outlet opening must be increased. Due to the extended spin funnel, the static pressure in the treatment medium at the outlet opening increases, which leads to high outflow rates at the outlet opening. Due to the additionally enlarged diameter of the outlet opening disproportionately more treatment medium flows out, the turbulence in the spinning cone becomes stronger and more treatment medium has to be circulated.
  • the filaments are passed through a film of treatment medium, which runs down along an inclined surface of a spin bath container formed as an overflow container.
  • a spinning guide in which a liquid flows out of peripheral discharge openings.
  • the spin guide serves to deflect a gel fiber.
  • the liquid passes between the gel fiber and the surface of the spinning guide, so that each filament is carried by the flow from the openings.
  • the spinline is completely immersed in a precipitation bath.
  • the invention is therefore based on the object to improve the known spinning plants so that the efficiency of the process is increased by increasing the spinning speed and a reduced need for treatment medium while improving the control of the precipitation process.
  • This object is achieved for a wetting device described above in that the wetting area is made of a porous material.
  • the wetting device according to the invention can also be used as a retrofit kit of existing spinning plants.
  • the solution according to the invention is therefore to guide the wetting medium through the guide wall to the filaments.
  • This solution which is quite simple in itself, surprisingly results in not only a good wetting of the filaments with the treatment medium, but also a considerably reduced friction between the filaments and the guide wall compared with the known wetting devices, since the treatment medium is pressed between the filaments and the guide wall and a friction-reducing effect Slip layer between the spun threads and the guide wall is formed. This sliding layer reduces the mechanical stress on the filaments and the susceptibility to failure of the spinning process. Due to the reduced friction, the transport speed of the spun yarns can be increased without affecting the spinning safety.
  • Suitable materials for the guide wall porous materials can be considered, which are constructed in developments of several layers of materials of different porosity.
  • Such porous materials may be sintered materials or materials constructed of woven or knitted or nonwoven fabrics.
  • the guide wall at least in the wetting region micro-pockets form, where the entrained with the spun yarns treatment medium is aufstaubar in operation between the spun yarns and the wetting area, so that the sliding layer gets thicker.
  • micro-pockets may be configured in the form of longitudinal grooves which extend transversely to the transport speed of the spun threads, or in the form of regularly or irregularly arranged recesses, similar to the surface of a golf ball.
  • a mesh or lattice-like surface structure also facilitates the formation of a sliding layer.
  • the supply of the treatment medium to the wetting area is particularly simple in construction if the guide wall is formed on a substantially hollow cylindrical body, through which the treatment medium can be supplied to the wetting area during operation.
  • the guide wall is thus part of the supply line of the treatment medium in this advantageous embodiment.
  • the hollow cylindrical body can be configured essentially cylindrical.
  • the wetting device can have at least one bearing, by means of which the body forming the guide wall can be attached rotatably to the spinning system.
  • the guide wall is formed along a substantially rotationally symmetrical body.
  • the permeable areas for the treatment medium may extend over the entire circumference or be divided into individual, circumferentially spaced areas.
  • the wetting device may have a rotation means by which the rotational movement of the guide wall can be influenced.
  • a rotation means may for example be a motor, for example an electric motor, or a brake.
  • the guide wall can be driven in the direction of the spun yarns or against the direction of the spun yarns, so that the wetting device additionally serves as a drawing means, through which a tensile force in the spun yarns upstream - for example, with a rotation of the guide wall at a speed greater than that Transport speed of the filaments - or downstream - for example, in a rotation at a speed less than or opposite to the transport speed of the filaments - in the filaments can be introduced.
  • the wetting device according to the invention can also be used simultaneously as a deflecting member, by means of which the transport direction of the filaments is changed.
  • the wetting surface can be designed to be curved, in particular in the transport direction of the filaments.
  • a plurality of wetting devices, at least two, in the transport direction of the spun yarns can be designed one behind the other.
  • each treatment device By connecting several wetting stages in series, a targeted and gentle coagulation of the filaments can be achieved over several stages.
  • This partial precipitation at each treatment device can be positively influenced once again by the fact that each wetting device is supplied with a different treatment medium, for example treatment media having different concentrations.
  • the successive wetting devices can be supplied in an advantageous development in series with the treatment medium.
  • a plurality of wetting devices with rotatably mounted bodies forming the guide wall can be arranged one behind the other. In this way, not only a multi-stage precipitation, but also a multi-stage stretching can be achieved.
  • a wetting device with a rotatably mounted body and a wetting device with a fixed guide wall can alternate.
  • the tensile stress in the spun yarns 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 yarns on the stationary guide wall.
  • the mechanical properties of the filaments can be decisively improved in this way compared to conventional wetting devices, without the spinning speed having to be reduced and thus the cost-effectiveness of producing the filaments suffers.
  • the wetting device according to the invention which can be used instead of a spinning bath container, can be used in a more versatile manner and at the same time can serve as a deflecting element and / or drawing agent.
  • the filaments 6 are produced by 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, namely the extrusion of spinning solution 5 into filaments 6, the subsequent stretching of the extruded filaments 6 in a gas line 7 and the wetting of the drawn filaments 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 yarns 6 in the gas line 7 can be done in a non-mechanical manner, for example, by the air flowing axially through the spun yarns whose speed is greater than the transport speed T of the spun yarns 6, or mechanically by a deduction mechanism 10, through which the spun yarns 6 deducted become.
  • the take-off unit 10 may have motor-driven rollers.
  • a blowing of the filaments 6 take place substantially transversely to the transport direction T of the filaments.
  • a blowing device 11 is used which directs a preferably turbulent gas flow onto the spun yarns 6.
  • the wetting of the drawn filaments 6 with treatment fluid 8 can, as shown in FIG. 1, be effected by a wetting device 9 according to the invention, in which a guide wall 12 between a supply line 13, through which the treatment medium 8 is fed to the wetting device 9, and the filaments 6 is arranged.
  • a wetting region 14 is provided, which is shown in Fig. 1 with a double-dot chain line.
  • the wetting area 14 is at least partially permeable to the treatment medium, such that the treatment medium 8 led through the supply line 13 emerges from the guide wall 12 in the wetting area 14 and wets the spun yarns 6 conducted along the guide wall.
  • the treatment medium 8 is pressed from the filaments 8, so that it drips or flows into a collecting device 15.
  • the treatment medium 8 is supplied via discharges 16 reprocessing steps, which are not shown in Fig. 1. After the reprocessing, the spent treatment medium 8 can be returned to the wetting device 9.
  • the embodiment of 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 yarns 6 are in the wetting region 14 on the guide wall 12, preferably between the spun yarns and the wetting region 14 is a sliding film of treatment medium 8.
  • FIGS. 2 to 5 further embodiments of the guide wall 12 comprising the body will be described.
  • the embodiments of FIGS. 2 to 5 are shown in a cross section along the plane E of FIG. 1.
  • the guide wall 12 forming the wetting area 14 is formed as a substantially planar and / or as a wall slightly curving perpendicular to the plane of the drawing. A deflection of the transport direction T of the spun yarns 6 therefore takes place in the wetting devices 9 of FIGS. 2 and 3 by means of a subsequently arranged deflecting member 17 or by the take-off mechanism 10 known from FIG.
  • the guide wall 12 forming body 18 is formed as a filled with treatment fluid, open channel. Solely by the static pressure of the treatment medium 8, this is pressed by a permeable for the treatment medium portion 19 of the wetting region 14 on the side of the filaments 6, where they are wetted by the treatment medium.
  • the region 19 may comprise the entire wetting region 14 or only parts thereof.
  • the body 18 of the wetting device 9 is configured substantially hollow-cylindrical, wherein the treatment medium 8 is guided in the interior of the hollow cylindrical body 18.

  • the entire wetting region 14 is designed to be permeable to the treatment medium. Since in the exemplary embodiment of FIG. 3 the guide wall 12 is also essentially straight in the transport direction T of the spun yarns, a deflection of the spun yarns must be effected by a downstream deflecting element 17 or a downstream take-off unit 10.
  • a downstream deflection member 17 can be omitted if the guide wall 12 is curved in the transport direction T of the spun yarns 6.
  • any desired deflection angle ⁇ can be achieved.
  • the deflection angle ⁇ results essentially from the degree of wrap of the body 18 through the filaments 6.

Due to the treatment medium emerging under pressure in these areas, a strong friction between the spun yarns 6 and the guide wall 12 is avoided in these embodiments in these critical areas.
  • FIG. 1 A further embodiment of a wetting device 9 according to the invention, which additionally serves as a deflecting element at the same time, is shown in FIG.
  • the body 18 of this embodiment is also hollow cylindrical, in particular as a tube formed with at least in the wetting area 14 throughout for the treatment medium permeable wall.
  • the interior of the tubular body 18 is acted upon with treatment medium 8.
  • the treatment medium emerges over the entire circumference of the body 18.
