Definitions

  • the invention relates to a system for the continuous production of a spunbonded web of aerodynamically stretched filaments made of thermoplastic material, with a spinnerette donating the filaments, below the spinnerette a continuously movable Ablegesiebband is arranged, on which the filaments can be stored for spunbond and wherein the Ablegesiebband a Suction device is provided for sucking air through the Ablegesiebband.
  • the spinnerette has spinneret holes from which the filaments of thermoplastic material can emerge. It is within the scope of the invention that the filaments are first passed through a cooling chamber into which process air for cooling the filaments can be inserted from an air feed booth. Furthermore, the filaments pass expediently into a drawing unit with a draw-down channel, which is followed by a laying unit, which preferably consists of at least one diffuser. Under the laying unit, the depositing device for filing the filaments to the spunbonded web is provided, wherein part of the depositing device is the above-mentioned continuously movable Ablitissiebband. On this Ablitissiebband the filaments are deposited to spunbond.
  • the reject screen is an endless belt.
  • the filaments are sucked by means of air, which is sucked by the suction device through the wire, as it were sucked onto the Ablegesiebband and deposited there as spunbond or spunbonded web.
  • the Deposition sieve is therefore permeable to air and the air is sucked through the Ablegesiebband to ensure a reliable storage of the spunbonded fabric.
  • a pressure roller or a pressure roller pair for the spunbonded fabric is usually arranged
  • spunbonded nonwovens are produced whose properties do not meet all requirements.
  • the spunbonded nonwovens produced with the known system often exhibit inhomogeneities with respect to their filament density and mesh size. Such inhomogeneities cause undesirable irregularities, in particular with regard to the nonwoven strength, the nonwoven elongation and the permeability of the nonwoven.
  • the known system is in need of improvement for this reason.
  • the invention is the technical problem of specifying a system of the type mentioned above, with the most uniform spunbonded filing and the most uniform arrangement of the filaments can be achieved in the filing.
  • the invention teaches a system of the type mentioned, which is characterized in that in the conveying direction of the Ablegesiebbandes at least two separate suction areas are arranged one behind the other, one of these suction areas is a main suction area assigned to the laying zone and that in the main suction area and in at least one further suction area, the suction rates are independently adjustable.
  • Deposition zone means in the context of the invention, the region of Ablegesiebbandes on which the filaments are deposited primarily or on which the main part of the filaments is stored.

It is therefore within the scope of the invention that the extraction speeds in the first suction area, in the second suction area and in the main suction area are independently controllable and / or controllable. According to the invention, the suction capacities in the three suction areas are independently adjustable or controllable and / or controllable.

  • the invention is based on the finding that in the first suction area, the quantities of air supplied with the discharge screen belt can be discharged with the proviso that the flow vectors are oriented at the boundary to the main suction area, as it were orthogonal to the discharge screen belt surface. This ensures that in the subsequent Hauptabsaug Colour entrained with the filaments to be deposited air can flow as freely as possible. If a portion of filaments is already deposited in the first suction area, the first suction area also fulfills the purpose of a transport lock in which the already deposited filaments are reliably held by the suction of the air on Ablegesiebband. In the main suction area adjoining the first suction area, the actual nonwoven storage or fleece formation takes place.
  • a functionally reliable non-woven storage is achieved in that the suction speed in the Hauptabsaug Scheme is greater than the suction speed in the first suction and also greater than the suction speed in the subsequent second suction.
  • the second suction area essentially serves to secure the transport of the deposited spunbonded fabric until it is solidified.
