Definitions

  • the invention relates to a device for producing a nonwoven from continuous filaments according to the preamble of claim 1, and the invention also relates to a multilayer nonwoven made from continuous filaments.
  • DE-PS 17 85 158, GB-PS 12 82 176 and GB-PS 12 97 582 devices for producing a nonwoven from continuous filaments are already known.
  • a sheet of threads is drawn off from a melt and from spinnerets with the aid of a gaseous propellant, and the individual threads are deposited on a deposit belt to form the fleece.
  • An important quality feature of the nonwovens is their uniformity and strength, the strength or the ratios of the strengths from the longitudinal direction to the transverse direction being essentially determined by the angle of lay of the individual threads - the direction of lay with respect to the direction of production.
  • a separator being associated with each draw-off tube.
  • the separator fulfills the task of separating the filaments from the accelerating air and simultaneously spreading the thread bundle.
  • the spreading angle is also predetermined by this spreading.
  • curtain process In a further device for producing a nonwoven from continuous filaments, the so-called curtain process has already been used, in which the many exhaust pipes mentioned above are dispensed with and also no spreading device (separators) are used.
  • the sheet of thread forming a flat forehand extends perpendicular to the production direction, ie the preferred laying direction runs parallel to the production direction.
  • the higher speed of the filaments in each case relative to the speed of the depositing belt leads to serpentine movements when the filaments are deposited. Individual filaments are then overlaid in certain areas.
  • a fleece produced with such a device does have a preferred strength in the longitudinal direction, that is, in the production direction, but the strength values in the transverse direction are extremely poor.
  • the invention has for its object to provide a device which allows the production of a nonwoven with a high degree of uniformity, and which allows to achieve predetermined strength and elongation values of the nonwoven in the desired directions.
  • the invention achieves this aim in the device mentioned in the preamble of claim 1 by the features of the characterizing part of patent claim 1.
  • the depositing angles can be set to any value, and a particular advantage is that such an adjustment is possible while the device is in operation.
  • a fleece produced with the device according to the invention can have both isotropic properties and preferred longitudinal strengths. Preferred transverse strengths are also possible without impairing the uniformity of the fleece, depending on the choice of the depositing angle.
  • the invention is also intended to create a multilayer nonwoven fabric made from continuous filaments, which has selectable strength values and a high degree of uniformity. That goal the invention ranges according to the features of claim 7.
  • FIG. 1 shows a spinning station, designated as a whole by the reference number 10, which comprises two spinning beams 12 and 14 arranged at a distance from one another in the transport direction 30 (production direction). A melt is fed to the spinning plates 18 via melt lines 16.
  • Each spinning plate 18 is used to distribute the melt over the production width, that is to say the width of a deposit belt 28.
  • the spinning plates 18 are interchangeably attached in the lowest part of the spinning beams 12, 14.
  • In the spinning plate 18 there is a variable number of holes called spinnerets through which the liquid spinning melt emerges from the spinning plate 18 as a sheet 50 in the manner of a curtain.
  • the thread sheet 50 moves along a blowing wall 20 which forms a stretching zone 22 for stretching the thread sheet.
  • the spinning station 10 further comprises, in each of the two spinning beams 12, 14, a thread take-off device 24 and a depositing device 26, by means of which the threads are spread to achieve high uniformity and are deposited on the depositing belt 28 moved in the transport direction 30 to form a fleece 52.
  • the curtain method used here thus works with a spreading device - comparable to the known separators - in order to achieve a specific direction in which the threads are deposited, namely a 90 ° direction, based on the spinning beam.
  • the threads are thus oscillated back and forth up to 90 ° to the spinning beam.
  • the deposit takes place first with the spinning beam 12, and a second layer is deposited on the first layer formed thereby in the other spinning beam 14, whereby a multi-layer fleece 52 is formed.
  • FIG. 2 shows the top view in Fig. 2 it can be seen that the spinning beams 12, 14 from their parallel, dashed position out in the direction of arrows 56 and 58 are pivotable about their axes of rotation 34, the longitudinal axes 32 of the spinning beams 12, 14 forming an angle 54 here.
  • the individual layers of the fleece 52 thus have the different storage directions or storage angles, which are predetermined by the spinning beams 12 and 14. These different storage directions are shown in Figs. 3-5.
  • FIG. 3 shows the course of the deposit 36 of the one spinning beam 12, while FIG. 4 shows the course of the deposit 38 of the other spinning beam 14.
  • the resulting storage image 40 which results from the multilayer nonwoven 52, which is produced by superimposing the storage profiles 36 and 38, is shown in FIG. 5.
  • the individual filing courses intersect, so that there is a cross filing with variable angles for the multilayer fleece. If the intersecting deposition courses 36 and 38 form an angle of 90 ° at the deposition image 40 at the intersection points, an isotropic fleece 52 is obtained with the same strength values in all directions.
  • FIG. 6 shows the spinning beam 12 in a plan view.
  • the spinning beam 12 is - as well like the spinning beam 14 - arranged on a bogie 42 and held and guided along the circular guide rails 44 by means of the guide rollers 46.
  • the guide rails 44 allow the spinning beam 12 to be rotated about the central axis of rotation 34, so that different angles of rotation 48 can be realized.
  • the guidance and mounting of the spinning beam 12 on the guide rails 44 is also illustrated in the perspective illustration according to FIG. 7, and it should be emphasized that the setting of different angles of rotation 48 is also possible during the operation of the entire spinning station 10. In practice, this represents a considerable advantage because it is not necessary to switch off and shut down the spinning station for setting new desired rotation angles 48 and thus for generating new storage images 40. Overall, the spinning station 10 can therefore be operated variably, because a cross deposit with variable angles can be achieved during the ongoing operation of the spinning station. A desired new nonwoven product can therefore be generated immediately during operation.
