Definitions

  • the invention relates to a device for producing a spunbonded nonwoven made of synthetic filaments according to the preamble of claim 1.
  • spunbonded nonwovens For the production of spunbonded nonwovens, it is generally known that a plurality of freshly extruded synthetic filaments after melt spinning and cooling are withdrawn together as a filament curtain, stretched and deposited on a deposition belt to form a nonwoven fabric.
  • the deposited filaments as well as the fiber formation within the spunbonded web produced by the filaments determine the physical properties of the spunbonded web.
  • the individual process steps for spinning, cooling, hiding and depositing the fibers must be particularly matched to one another in order to produce the spunbonded fabric with the desired properties continuously.
  • DE 195 21 466 AI discloses a device in which the filaments between a spinning device and a storage device is guided by a more or less closed shaft system.
  • the cooling device provided underneath the spinning device has a cooling shaft which opens with its end in a process shaft.
  • the process shaft is assigned a diffuser at the end facing a storage belt.
  • a cooling air which is passed to cool the filaments in the cooling shaft, and in the process shaft, a process air, which is used essentially for VerStrecken and for depositing the filaments, is used in the cooling shaft.
  • additional connections are provided in the process shaft to initiate or remove auxiliary air flows as required in the process shaft.
  • such auxiliary air streams basically have the disadvantage that only an air-fiber flow optimized in front of the deposit can be produced. The air-fiber flows generated for cooling the filaments and for stretching the filaments remain unaffected.
  • This object is achieved in that between a filament outlet of the cooling shaft and a filament inlet of the process shaft, a short free path is formed, in which the cooling air is dissipated in an environment.
  • the invention was also not suggested that from WO 2000/065133 an apparatus for producing a spun nonwoven is known in which the stretching device is arranged at a distance below a cooling device.
  • the drawing device has a draw-off nozzle which is operated with a compressed-air flow in order, on the one hand, to generate a suction effect on the inlet side and, on the other hand, to generate an intensive air-fiber flow for drawing off the filaments.
  • a leadership of the filaments with relatively low air flow and low pressure conditions within a shaft system is not possible with the known device.
  • the invention has the particular advantage that the cooling air and the process air can be set independently of each other to the respective filament type.
  • the entrainment of the cooling air from the cooling shaft into the process shaft is advantageously substantially avoided by a short free travel, in which an exchange with the ambient air can take place.
  • It is essential that the cooling air within the cooling Chute is guided as possible in the direction of the filaments, so that a supporting conveying effect in addition to the cooling begins.
  • the filament curtain can be safely introduced into the process shaft, in which the injected process air generates a necessary for the hiding of the filaments Liehe pulling force on the filaments.
  • the process air is supplied separately to the process shaft.
  • the relatively low air velocity within the process shaft also favors the deposition of the fibers, wherein the diffuser of the laying device leads to a widening of the filament curtain and corresponding distribution of the filaments for spunbonding.
  • the development of the device according to the invention is preferably carried out, in which the free path is formed by a distance between the filament outlet of the cooling shaft and the filament inlet of the process shaft.
  • the outlet cross section of the filament outlet and the inlet cross section of the filament inlet can be matched to one another such that an unhindered transition of the filament bundle without the formation of air turbulences is possible.
  • the distance between the filament outlet of the cooling shaft and the filament inlet of the process shaft is designed according to the titre of the filaments and volume flow of the cooling air flow with a size in the range of 10 mm to 500 mm.
  • the avoidance of air turbulence during the transition from the cooling shaft into the free path and from the free path into the process shaft can advantageously be further improved by several adjustable air baffles are provided, which extend laterally along a width of the cooling shaft and / or the process shaft.
  • the cooling shaft is arranged at least with a section facing the spinning device with air-permeable shaft walls between two opposing blowing chambers, through which the cooling air can be injected from both sides in the cooling shaft ,
  • the filaments on both sides of the spinning device can be uniformly cooled by a cooling air flow.
  • the drawing of the filaments can likewise be carried out particularly uniformly in that an inlet region of the process shaft with air-permeable shaft walls extends between two opposite air ducts through which the process air can be injected in the process shaft.
  • the filament curtain can be uniformly stretched within the process shaft.
  • the air flow of the process air during injection into the process shaft can be advantageously further improved by having the process shaft for connecting the air ducts opposite air inlet openings with a plurality of air guide elements.
  • lamellar baffles which are arranged one above the other and have an adjustable design, have proven to be suitable as air-guiding elements.
  • the process air can be blown over the entire width of the process shaft in a predetermined flow direction.
  • the development of the invention is particularly advantageous, in which the air ducts are coupled to a fan which is connected via a suction connection with a suction chamber of the storage device. This allows the process air used for stretching and depositing the filaments to be used continuously.
  • the suction chamber is advantageously arranged with a suction opening below a depositing belt of the depositing device, the suction opening of the suction chamber being associated with a diffuser outlet of the diffuser assigned to the depositing belt opposite the side.
  • the development of the invention is particularly advantageous, in which at least one air inlet slot is formed in a transition region between the process shaft and the diffuser, through which air inlet slot an additional process air the Diffuser can be fed.
  • additional storage effects within the diffuser can be generated independently of the process air.
  • the additional process air could be generated by a suction effect from the environment or actively by a blower.
