Definitions

  • the present invention relates to a system and a method for producing a spunbonded fabric of endless filaments, which consist for example of thermoplastic material. Endless filaments differ because of their quasi-endless length of staple fibers, which have much smaller lengths of, for example, 10 to 60 mm.
  • nonwoven web which is typically produced by depositing the filaments on a storage belt.
  • the tray is usually solidified by means of a thermal calender. This results in nonwovens with good strength and small thickness. Heavier or more voluminous Filamentablagen are more difficult to solidify, since the energy input is limited in the middle of the product in the time available and in particular for heating up to the vicinity of the melting point of the plastic is no longer sufficient. If heavier or more voluminous nonwovens are to be produced, other solidification processes are expedient, in particular mechanical needling and hydraulic needling or thermobonding (preferably by means of hot air).
  • the EP 1408148B2 shows a spunbonding machine, in which the endless filaments are deposited by a spinning tower on a first storage belt. Immediately behind the filing of the endless filaments suction boxes are arranged under the first storage belt, which hold the endless filaments on the first storage belt. A first consolidation takes place by means of heated calender rolls. By means of an evacuated roll, the endless filaments are transferred to a second deposition belt, on which the solidification takes place by means of water jets. At very high transport speeds of the spunbonded fabric of more than 250 m / min, the calender rolls can not transfer sufficient energy into the endless filaments for preconsolidation, since the residence time in the contact area of the rolls is too low. Another disadvantage is the transfer of the filaments from the first to the second storage belt by means of suction roll, as at high speeds undesirable distortions can occur.
  • a disadvantage of this prior art is the low operating speed of the system, since in particular the introduction of heat by calender in the continuous filaments requires a predetermined energy density. With a higher working / transport speed of the continuous filaments, the calenders would have to be heated far above the melting point of the thermoplastic material in order to transfer the energy in the shorter contact time between the rollers. Any smallest disturbance or irregularity at this location would result in undesirable sticking of the continuous filaments, whereby the subsequent hydroentangling would at least partially not achieve the desired effect. In other words, the hydroentanglement would have to be significantly oversized in order to uniformly solidify and structure the nonwoven, which would already be pre-consolidated in places by means of bonding points.
  • Another disadvantage is the introduction of water for pre-moistening, which must be removed from the web in a further complex process step.
  • the object of the invention is the development of a system and a method for producing a spunbonded nonwoven filaments at high speeds.
  • the invention relates to a plant for producing a spunbonded web, comprising a spinnerette with a diffuser for the production of continuous filaments, with a first depositing belt, which is adapted to transport the endless filaments and transfer to a subsequent second depositing belt, wherein at the second Ablageband at least one means for hydroentanglement of the continuous filaments is arranged to a spunbonded, wherein the spunbond is subsequently solidified and / or structured by means of at least one further hydroentanglement.
  • the invention is characterized in that the first storage belt transports the continuous filaments dry and unconsolidated, wherein a roller is arranged at the end of the first storage belt or at the beginning of the second storage belt, so that the endless filaments are guided around the roller with a small angle of wrap.
  • the endless filaments Due to the high transport speed of the endless filaments, in contrast to the prior art, no solidification, compaction or calendering of the continuous filaments takes place on the first deposition belt.
  • the endless filaments are thus transported unconsolidated and dry at a high speed of at least 250 m / min on the first storage belt.
  • the system dries the continuous filaments dry on the first storage belt, ie that the endless filaments are not sprayed or treated with water or another liquid, which can be troublesome for the further treatment or can reduce the Auflagereibung the continuous filaments on the first conveyor belt.
  • a low frictional force is generated on the endless filaments by means of a roller, by wrapping the roller around a small angle.
  • the angle can be up to 45 ° and is generated by immersing the roller with little force in one of the depositing belts. Because the depositing belts yield elastically, the endless filaments are guided around the roller with a small wrap angle, so that an increased friction occurs between the endless filaments and the roller. which withstands a limited tensile load. So much tension can be built up that the endless filaments can be guided over the gusset between the storage belts without sagging.
  • the continuous filaments will be transported on the storage belts at a speed of at least 250 m / min.
  • Very light spunbonded nonwovens can be produced at high speed.
  • the roller is permeable to air and besaugbar.
  • the entrained air entrained at these high speeds can be extracted.
  • the storage belts can be operated at the same speed, or alternatively, the second storage belt can be operated at a slightly higher speed.
  • the roller when the roller is arranged at the beginning of the second storage belt, the roller must be drivable and operated at a slightly higher peripheral speed than the transport speed of the second storage belt.
  • the decisive factor is a slight pull or a wrap around on the Apply endless filaments, so that they can overcome the gusset between the storage belts without significant slack.
  • the continuous filaments can be treated with a positive or negative delay.
  • the wrapping angle of the endless filaments can be adjusted around the roller.
  • the system is designed to accommodate a further component between the storage belts, so that, for example, a carded nonwoven fabric can be introduced in order to be connected together on the second storage belt with the endless filaments.
  • the process for producing a spunbonded fabric provides to produce continuous filaments in a spinnerette with a diffuser and to deposit on a first storage belt, the first storage belt transports the endless filaments to a second storage belt and passes to this, wherein the continuous filaments on the second storage belt to a spunbonded fabric solidify by means of hydroentanglement and subsequently solidify by means of at least one further hydroentanglement and / or structure.
  • the inventive method is characterized in that the endless filaments are transported dry and unconsolidated on the first storage belt, wherein the endless filaments at least partially wrap around a roller which is arranged at the end of the first storage belt or at the beginning of the second storage belt to the To reduce sag of Endlosfil noir in the gusset between the first and the second storage belt.
  • the creation of a terminal point facilitates the transition from the first to the second filing belt. Therefore, the detachment of the continuous filaments from the depositing belt at the transition to the depositing belt is promoted by the creation of a clamping point by means of the roller. The replacement of the spunbonded from the storage belt to the suction drum is facilitated by the generation of the terminal point by means of the roller.
  • the transport speed of the continuous filaments is at least 250 m / min, preferably at least 400 m / min.
  • the plant is suitable for light spunbonded nonwovens with a basis weight of 60 g / m 2 .
  • the lighter the spunbond, the higher the transport speed may be, for example, at a basis weight of 15 g / m 2 from 250 m / min to 1000 m / min.
  • FIG. 1 shows in a first embodiment according to the invention a plant 1 for producing a spunbonded fabric, in which a spinnerette with diffuser 2 produces endless filaments 3 and deposits them on a first depositing belt 4.
  • the storage belt 4 is formed as an endless circulating belt that is guided by at least two, in this embodiment by four deflection rollers 4a, 4b, 4c, 4d, and driven by at least one deflection roller.
  • a first sow box 5 is arranged below the storage belt 4, which is assigned to the spinnerette.
  • a further sowing box 6 with which the continuous filaments 3 are held on the storage belt 4 by means of induced draft.
  • the storage belt 4 on a plurality of perforations can be sucked through the air in sufficient quantity.
  • the system 1 drives the endless filaments 3 dry on the first storage belt 4, ie that the endless filaments 3 are not sprayed or treated with water or another liquid.
  • no solidification, compaction or calendering of the endless filaments 3 takes place on the first storage belt 4.
  • the endless filaments 3 are thus unconsolidated and dry at a high speed of at least 250 m / min, preferably at least 400 m / min, transported on the first storage belt 4.
  • the first storage belt 4 is followed in the transport direction by a second storage belt 7, on which the subsequent solidification of the endless filaments 3 to form a spunbonded web 11 takes place.
  • the second storage belt 7 is also formed as an endless circulating belt that is guided by at least two, in this embodiment by four deflection rollers 7a, 7b, 7c, 7d and driven by at least one deflection roller.
  • the storage belt 7 is also formed as a perforated air or water-permeable belt. At the transfer point between the first and the second storage belt 4, 7, the distance between the storage belts 4, 7 is minimized so that an evacuated transfer is not required. Due to the high transport speed of the endless filaments 3, the sag of the endless filaments 3 in the gusset between the deflection rollers 4b and 7a is very small.
  • a roller 8 is arranged in the region of the deflection roller 7a above the depositing belt 7 and exerts a limited pressure on the endless filaments 3. In contrast to a calender, the roller 8 is moved to the storage belt 7 on gap. Characterized in that the storage belt 7 yields elastically, the endless filaments 3 are guided around the roller 8 with a small angle of wrap, so that an increased friction between the continuous filaments 3 and the roller 8 occurs, which withstands a limited tensile load.
  • the storage belt 7 with a slightly higher Speed is operated as the storage belt 4.
  • the speed difference can be up to 0.5%.
  • the roller 8 may be air-permeable or have a smooth closed jacket.
  • the roller 8 may also have a textured surface to increase friction with the continuous filaments 3.
  • the roller 8 may be co-rotating or driven.
  • the roller 8 can be arranged to provide pressure the deflecting roller 7a or with the depositing belt 7 on the endless filaments 3 exerts and this easily (with defined gap) clamped. If the roller 8 is driven, it is possible to set a delay of, for example, 2-5% of the continuous endless filaments 3 with the depositing belt 7 or the deflection roller 7a.
  • the roller 8 At the high transport speed of the endless filaments 3, it may be advantageous to form the roller 8 as an air-permeable roller and to suck, since this unwanted entrained air currents can be derived. If both storage belts 4, 7 operated at an identical speed, the roller 8 can be operated at a slightly higher speed than the storage belt 7. The peripheral speed can be up to 0.5% greater than the transport speed of the storage belt 7. Thus the endless filaments 3 are pushed onto the depositing belt 7, so that the sag of the endless filaments 3 in the interstice between the depositing belts 4, 7 is reduced.
  • a first solidification of the continuous filaments into a nonwoven fabric 11 After the transfer of the endless filaments 3 to the second storage belt 7 takes place by means of a nozzle beam 9, a first solidification of the continuous filaments into a nonwoven fabric 11.
  • the nozzle beam can be operated with a low pressure of for example 10 - 40 bar, only to achieve a pre-consolidation.
  • a suction box 10 is arranged below the storage belt 7, with which the water of the nozzle beam 9 is sucked through the storage belt 7.
  • the solidification effected by the first nozzle bar 9 can advantageously be very light, so that structuring can take place simultaneously on the following suction drum. If there is no subsequent structuring, the nozzle bar 9 can also be operated at a higher pressure of, for example, 40-400 bar.
  • the nonwoven fabric 11 is conveyed around a first suction drum 12, which is arranged above the storage belt 7.
  • At least one further nozzle bar 13 acts on the fleece 11 at a high pressure of 40-400 bar in order to give the fleece 11 sufficient strength and optionally a structuring.
  • the structuring is generally carried out by means of a patterning of the suction drum 12, via which a shell with a formative pattern can be drawn up.
  • a circulation of about 180 ° about the first suction drum 12 another circulation takes place about a second suction drum 14, on which at least one further nozzle bar 15 also solidifies the nonwoven with a high pressure of 40-400 bar and, if appropriate, restructures it again.
  • a further treatment of the web 11 in a subsequent system for dissection, drying and / or winding is no longer shown in this view, but belongs to the entire system concept.
  • FIG. 2 differs from the previous embodiment only in three points: the roller 8 can be arranged horizontally movable by means of sliding strips. Since the storage belt 7 is vertically yielding after the deflection roller 7a due to its elongation, by a horizontal process of the roller 8 of the guide roller 7a in the direction of suction box 10, the gap between storage belt 7 and roller 8 are varied, which the wrap angle of the endless filaments 3 to the Roller 8 changes and thus the connected friction force.
  • a further nozzle bar 16 is arranged below the suction drum 12 and below the depositing belt 7 in order to achieve a first compaction by the depositing belt 7 and, if necessary, to assist a detachment of the preconsolidated nonwoven 11 from the depositing belt 7.
  • a further improvement of the system 1 can be achieved by at least one deflection roller, in this example the deflection roller 7a, being displaceably arranged in order to reduce the tension on the deposition belt 7 and thus simplify the exchange of the deposition belts.
  • both storage belts 4, 7 can be operated at an identical speed.
  • the roller 8 must be operated at a slightly higher peripheral speed than the storage belt 7.
  • the peripheral speed can be up to 0.5% greater than the transport speed of the storage belt 7.
  • the endless filaments 3 are pushed onto the storage belt 7, so that the sag of the endless filaments 3 in the gusset between the storage belts 4, 7 is reduced.
  • a stretching of the endless filaments 3 can take place when the roller 8 is operated at a greater speed of 2-5%.
  • the roller 8 can be configured as a non-driven revolving roller 8. Alternatively, it may also be driven to act on the continuous filaments 3 with a positive or negative draft of 2-3%.
  • the roller 8 is arranged in the end region of the storage belt 4, if possible so that the roller cooperates with the deflection roller 4b.
  • the roller 8 with the storage belt 4 a gap, whereby a frictional force acts on the continuous filaments 3 due to a small wrap angle, so that in connection with the wrapping of the endless filaments 3 around the suction drums 12, 14 a slight tensile stress acts on the continuous filaments 3, so that they are not in sag the gusset between the storage belts 4 and 7.
  • the roller 8 may be formed here as an air-permeable and evacuated roller to remove the drag air from the plant.
  • the storage belt 7 has been modified and a further deflection roller 7e inserted to create space in the region of the gusset for a further application, for example, a winding 17 for a carded web to combine with the continuous filaments on the second storage belt 7.
  • the deflection roller 7a is arranged at least horizontally displaceable here as well.
  • the speed of the storage belts 4 and 7 may be identical in this embodiment, or the speed of the storage belt 7 may be slightly above the speed of the storage belt 4.
  • the train on the endless filaments 3 is generated either by the wrapping and thus friction with the roller 8, or by the higher speed of the storage belt 7.
  • the roller can not be driven and running running.
  • the roller 8 may be driven to set a positive or negative bias of 2-5% with the deposition belt 4 so that either the roller 8 is driven faster or slower.
