Definitions

  • the invention has for its object to find a method and the associated device, with which this easy endurenverschl angraph is improved and yet a good binding of the pulp fibers in the carrier fabric can be achieved. In addition, care must be taken that the pulp layer applied does not lose or lose a little when effectively bonded to the carrier fleece.
  • the spunbonded nonwoven is calendered prior to coating with the superabsorbent material for preconsolidation, then abandoned the Woodpulp Anlagen with a carded web layer and this together with a hydrodynamic water needling solidified and then dried.
  • Solidification of the calendering of the continuous fiber web prior to further processing not only improves the abrasion resistance of the final product, but also reduces pulp loss in the water kernel in and through the web. It should be noted, however, that this calendering is not too strong. If the solidification is too high, the bonding points are too varied, then a connection of the pulp layer by the water needling with the calendered web is difficult.
  • the fleece at the end of the binding process after drying can be calendered again, whereby a solid involvement of all surface fibers can be achieved.
  • the roller adjacent to the spunbond layer needs to be heated.
  • the pulp layer is hydrodynamically bonded to the web in this manufacturing process, otherwise the product can not be used in practice because of film formation. According to the invention, it is provided that a further preconsolidated carded web is applied to the pulp layer and only the three layers are needled together hydrodynamically. Even then, a final calendering is an advantage.
  • the upper cover fleece 12 should also be pre-consolidated with a calender 11.
  • said water needling takes place, which in this embodiment may also be multi-step from both sides, since the pulp layer is provided on both sides by a pulp layer Fleece is covered.
  • the subsequent drying takes place here with another type of fürbeblcommunungstrockner 9, the screen drum 9 ', the fan is assigned externally.
  • the calender 15, 16 can be run through, but then both rollers 15, 16 are to be heated.
