Definitions

  • WO 01/53588 a method for producing a sandwich fleece from at least two cover nonwovens made of man-made fibers and / or natural fibers and a middle intermediate layer of pulp fibers is known.
  • the sandwich fleece runs into a water needling device and then into a dryer.
  • the bottom cover layer formed from continuous fibers passes through a pair of calender rolls to press the fiber layer before the pulp is applied.
  • Sandwich nonwovens manufactured in this way are optimal with regard to a loss-free amount of pulp fiber, but they are flat in the end product, they are not voluminous.
  • the object of the invention is to develop a method with which a voluminous sandwich fleece can also be achieved with this type of hydrodynamic bonding.
  • the invention proposes to increase the volume of the deposited, shaped cover webs, which are in any case produced, before the pulp layer is added.
  • This can be done by compressing, crimping, hydrodynamically treating or shrinking at least parts of the fibers of the cover layer.
  • the volume generated in the fleece must be fixed so that it is retained by the water needling during the final consolidation.
  • FIG. 1 shows a schematic illustration of a discontinuous offline system with a nonwoven pretreatment after the separate spinning unit
  • FIG. 2 shows a discontinuous inline system with a nonwoven pretreatment after the spinning process
  • FIG. 3 shows a spunbonded nonwoven system with water needling.
  • the endless filaments are formed in the unit 1 and placed on an endless belt 2.
  • the fleece 3 formed with a weight of z. B. 8 - 15 g / m 2 is then thermally solidified under pressure by means of a calender 4. Only now can the nonwoven be manipulated and rolled up here.
  • the roll 5 with the spunbond fleece 3 is to be submitted to a separate machine system for producing a sandwich fleece.
  • This system then consists of roll 5 for the ground cover fleece and a unit for increasing the volume of the fleece.
  • this unit is a simple hydrodynamic needling device 6 with a smooth or better structured drum surface 7.
  • a pair of calender rolls with gear meshing rolls or a fleece shrinking device can also be used.
  • the volume of the calendered nonwoven 3 must be increased in order to soften the grip of the end product.
  • the pulp is given a pulp layer, e.g. B. by means of the air-lay device 8.
  • the pulp layer is z. B. 20-60 g / m 2 .
  • the top layer of roll 5 ' has to be given up. B. by another pre-spunlace device 6 '.
  • the three-layer fleece is to be connected to one another in its layer, specifically by means of a hydrodynamic needling device 9 with water needling on both sides.
  • the PLC fleece is to be dried in device 10 and rolled up with device 11.
  • FIG. 2 Another, but ultimately also discontinuous system is shown in FIG. 2.
  • the calendered nonwoven 3 is first increased in volume before rolling up with the unit 5 ".
  • this is done by means of a simple pre-spunlace device 6" is integrated into the spinning system.
  • a structuring pair of rollers or an upsetting device can also be conceivable here.
  • a dryer 14 should follow, or at least a water suction device.
  • the Deckviies now achieved on the roll 5 ' is already increased in volume and soft to the touch. It can now be presented to the sandwich fleece system for both the floor fleece 5 "and for the cover fleece 5 '". In between, the pulp with the unit 8 has to be placed and everything has to be solidified and dry in the device 9 as before.
  • FIG. 3 discloses a spunbonded nonwoven system according to FIG. 2, but in which the pair of rollers 4 with the pre-spunlace device 6 "is replaced by a compacting unit, that is to say with an opposing compacting belt 2 ', both of which are flowed through by the water jets of a nozzle bar 12 After the more compact, the fleece is then increased in volume, which is done by the nozzle bar 13, which is also assigned to the endless belt 2. Finally, the fleece is to be dewatered by suction and / or by drying.

Abstract

On connaît la fabrication d'un non-tissé sandwich à l'aide d'au moins deux non-tissés de couverture en fibres chimiques et/ou naturelles et d'une couche intermédiaire centrale constituée de fibres de pulpe. Après la superposition des couches de non-tissés, l'ensemble obtenu est placé dans un dispositif d'aiguilletage hydrodynamique provoquant l'assemblage et la consolidation des couches. Pour que l'on puisse obtenir un produit non-tissé de ce type qui soit plus volumineux et ainsi plus mou, il faut qu'au moins le volume du non-tissé de couverture inférieur chaque fois déposé et mis en forme soit augmenté avant le dépôt de la couche de pulpe. Cette augmentation de volume est obtenue, selon l'invention, par foulage en largeur d'un non-tissé présentant une certaine largeur ou par calandrage, par exemple au moyen de cylindres du type roue dentée s'engrenant l'un dans l'autre, ou bien par un pré-aiguilletage hydrodynamique additionnel.
