Definitions

  • the invention is based on the object, a method and the associated device to find with which this easy surface wear ability improves is still achievable and good binding of the pulp fibers in the carrier nonwoven. Furthermore Care should be taken to ensure that the pulp layer applied is effective Do not connect or get lost with the carrier fleece.
  • the invention provides the solution of the problem in that the spunbonded nonwoven before coating with the superabsorbent Pre-consolidated material, as needled with air or calendered for preconsolidation is abandoned, then the Woodpulp slaughter and both together with a solidified hydrodynamic water needling and then dried.
  • the Solidification of the calendering of the continuous fiber fleece before further processing not only improves the abrasion resistance of the final product but also reduces it a pulp loss in Wasservernadein in and through the web through. But it is to note that this calendering is not too strong. Is the solidification too high, the binding points are too diverse, then is a compound of the pulp layer made difficult by the water needling with the calendered fleece.
  • the fleece at the end of Binding process after drying can be calendered once again, creating a firm integration of all surface fibers can be achieved.
  • the Spunbond layer is adjacent.
  • FIG. 1 also on a permeable drum according to FIG. 2 can be carried out.
  • the drying process on a screen drum device 8, 9 with aeration follows.
  • the device 8 is the screening drums of the Fan directly assigned to the front.
  • the solidification must be so be intense that a higher, satisfactory abrasion resistance on the final product arises.
  • only the roller 16, with the Spunbondvlies Touch has to be heated.
  • the continuation system according to FIG. 2 corresponds to that of FIG. 1, there is only one second, only slightly pre-consolidated endless fiber fleece 12 produced with the device 10, which of course also presented with a role, not shown, so prefabricated can.
  • This also applies to the carrier fleece according to Fig. 1 with the device 1 - 4. Anyhow the upper cover fleece 12 should also be pre-consolidated with a calender 11 be.
  • the unit 10 would represent a device like it is denoted by the reference numerals 1 '- 4', while in place of the carding a Spunbond observed similar as denoted by the reference numerals 1, 2 arranged is.

Claims (11)

  1. Procédé de fabrication d'un voile composite constitué d'au moins un voile porteur comme un voile non tissé et de, par exemple, une couche de pulpe de bois destinée à la fabrication d'un produit sanitaire et disposée sur ce voile porteur, et caractérisé en ce que, avant l'enduction, le voile non tissé est compressé à sec avec le matériel super-absorbant destiné à la consolidation préalable. La couche de pulpe de bois est ensuite déposée avant que le voile non tissé et la couche de pulpe de bois soient consolidés puis séchés par aiguilletage hydraulique aérodynamique.
  2. Procédé selon la revendication 1, caractérisé en ce que la consolidation et la compression préalables sont réalisées avec de l'air comprimé.
  3. Procédé selon la revendication 1, caractérisé en ce que la consolidation et la compression préalables sont réalisées par calandrage.
  4. Procédé selon les revendications 1 à 3, caractérisé en ce que une couche de revêtement est déposée sur le matériau super-absorbant avant la consolidation par aiguilletage hydraulique sur le voile composite en deux parties.
  5. Procédé selon la revendication 4, caractérisé en ce que un voile non tissé préalablement consolidé et calandré a été prévu comme couche de revêtement.

  7. Procédé selon les revendications 1 à 6, caractérisé en ce que la consolidation préalable et la consolidation par calandrage ont lieu avant l'aiguilletage hydraulique, par simple liaison des fibres du voile porteur.
  8. Procédé selon une des revendications 1 à 7, caractérisé en ce que le voile composite séché est à nouveau calandré mais cette fois avec une énergie plus grande.
  9. Procédé selon une des revendications précédentes, caractérisé en ce que un voile de carde calandré est tout d'abord constitué comme voile porteur, un voile non tissé étant apposé comme couche de revêtement sur le voile de,carde, après la couche de pulpe.
  10. Dispositif de fabrication d'un produit sanitaire à partir d'un voile non tissé et couche de matière super-absorbante pour l'exécution du procédé selon une des revendications 1 à 9, tous deux étant constitués de :
    a) un dispositif de filage ou de cardage (1, 2 ; 10 ; 1'-4'),
    b) un dispositif de consolidation par air ou de calandrage (5, 11),
    e) un dispositif (6) pouvant le cas échéant être connecté directement et destiné à déposer une couche de pulpe de bois sur le voile porteur préalablement consolidé,
    f) un dispositif d'aiguilletage hydraulique (7 ; 13, 14) dont les rayons hydrauliques sont orientés vers la couche de pulpe de bois,
    g) un dispositif de séchage (8, 9) et
    h) le cas échéant un autre dispositif de consolidation et de calandrage (15, 16)
  11. Dispositif selon la revendication 10, caractérisé en ce que un autre dispositif de filage ou de cardage (10) a été commuté devant le dispositif d'aiguilletage hydraulique hydrodynamique (1,2,5) en vue de former une couche de revêtement, le dispositif de filage ou de cardage suivant un dispositif de consolidation et de calandrage (11) lui-même situé devant le dispositif d'aiguilletage hydraulique (13,14).
