Definitions

  • the invention relates to a device for manufacturing of a spun-bonded nonwoven made of core-shell structure Bicomponent threads of two different thermoplastic Plastics.
  • the invention has for its object to indicate how a structurally simple device of type mentioned at the beginning.
  • the invention is based on the knowledge that a known two-channel wide slit tool can be and to this via a distributor plate as it were two spinneret plates can be connected, the desired uniform for the nonwoven production Ensure bicomponent thread distribution.
  • the nucleation plate is in a lower recess of the Distribution plate used and by the together with the Distribution plate from below with the wide slot tool screwed spinneret plate held. It also recommends itself, the core formation holes and spinneret holes in to arrange a rectangular grid. Simple and manageable conditions arise when the Outlets of the feed holes for the core Plastic melt in cross rows between two Coring holes are arranged and / or the outlets of the feed bores for the one forming the jackets Plastic melt in transverse rows between the transverse rows the spinneret holes between two in the longitudinal direction adjacent spinneret holes are arranged.
  • the device shown in the figures is used for Manufacture of a spunbonded fabric from a core-shell structure having bicomponent threads of two different thermoplastics.
  • the device initially has a two-channel wide-slit tool 1 on which at its bottom two straight and parallel to each other Channel outlet slots 2, 3 for the two plastic melts having.
  • the wide slot tool 1 is from two extruders (not shown) with the two Plastic melts supplied.
  • At the bottom is the Wide slot tool 1 a distributor plate 4 with feed holes 5, 6 for the two plastic melts superior.
  • the distributor plate 4 is in turn Underside of a nuclear imaging plate 7 set in Longitudinal and transverse direction of the wide slot tool 1 in core formation holes arranged in a uniform grid 8 for the core 9 of the bicomponent threads.
  • the core formation plate 7 in turn is on its underside a spinneret plate 10 in front, which in turn in Grid of the core formation holes 8 arranged in Diameter compared to the core formation holes 8 has enlarged spinneret bores 11.
  • 6 is the Arrangement made as follows:
  • the inlets 12 of the Feed holes 5 for the core forming Plastic melt is in the area of one Channel exit slot 2, while the inlets 13 of the Feed holes 6 for the shells 14 forming Plastic melt in the area of the other channel outlet slot 3 lie.
  • the outlets 15 of the feed bores 5 for the plastic melt forming the cores 9 are in at least one upper distribution space 16 the Nuclear formation plate 7 and the outlets 17 of the Nuclear forming plate 7 through extended feed holes 6 for the plastic melt forming the shells 14 in at least one upper distribution space 18 of the Spinneret plate 10 arranged.
  • a distribution space 16 running in the transverse direction detect.
  • Several such distribution rooms are parallel arranged side by side and can be in at one end Longitudinal direction of the slot tool 1 to one single distribution space 16 to be connected.
  • At the spinneret plate 10 is basically a single one Distribution room 18 because the holes between the other plastic melts are missing.
  • FIG. 1 also shows that the nucleation plate 7 in a lower recess 19 of the distributor plate 4 is used is and by the together with the distribution plate 4 of screwed down with the wide slot tool 1 Spinneret plate 10 is held.
  • 2 and 3 one in turn that the core formation holes 8 and Spinneret bores 11 in a rectangular grid are arranged.
  • the outlets 15 are the Feed holes 5 for the cores 9 forming Plastic melt in transverse rows 20 between two Coring holes 8 are arranged, while the outlets 17th the feed holes 6 for the shells 14 forming Plastic melt in transverse rows 21 between the transverse rows 20 of the spinneret holes 5 between two in In the longitudinal direction adjacent spinneret holes 5 are arranged are.
