Definitions

  • the invention relates to a method for producing a composite nonwoven Absorption and storage of liquids or the like consisting of a carrier fleece, that for solidification z. B. is hydrodynamically needled, and one on the solidified carrier fleece abandoned cellulose layer such as from wood pulp fibers that is brought into firm contact with the carrier fleece.
  • a method of this kind is going out EP-B-0 540 041.
  • the carrier fleece is essentially not used for consolidation water needled, but to the liquid permeability of the carrier fleece to increase.
  • the superabsorbent is then applied to the needled nonwoven Pulp applied in one layer, both brought into good binding contact and then dried the composite nonwoven.
  • the invention has for its object a method and an implementation this method to develop necessary device with which such Woodpulp loss in the process of effective connection with the carrier fleece can be avoided.
  • the invention provides that solidified carrier fleece a thin intermediate layer made of a microfiber, e.g. B. after the meltblown process, and the layer of cellulose fibers first put on this intermediate layer and everything is connected. This connection then expediently takes place again with the hydrodynamic one Needling.
  • the intermediate layer present in such a product serves furthermore advantageously as a barrier for the liquid to be absorbed by the product. Nevertheless, this barrier layer is not an airtight separating layer, which the would prevent breathability of the product.
  • a fleece made of polyester and / or polypropylene fibers can be used as the carrier fleece.
  • This fleece is to be needled with water first, that is, to be consolidated. Then a thin layer of a microfine fiber, which is less than 1 - 5 ⁇ m thick, is sprayed onto the nonwoven so stable and evenly distributed on the nonwoven.
  • the cooling finest fibers in a layer with a weight of between 1 - 4 gr / m 2 , preferably 2 gr / m 2 combine to form a kind of film and yet do not represent such an absolutely dense layer.
  • the cellulose fibers are then z , B. abandoned with the known airlay method.
  • connection of this superabsorbent pulp layer with the carrier fleece covered by the intermediate layer of microfiber is then produced by means of water needling, the fine cellulose fibers now being no longer or only slightly able to be sponged by the carrier unit, that is to say the use effect of the product is retained.
  • the carrier fleece is made of the polyester fibers and / or the polypropylene fibers manufacture.
  • the carrier fleece serves as a fleece laying device.
  • B. a card 1-4 or a spunbond system, which is not shown here.
  • the card consists of one Box feeder 1 with a shaker chute 2 arranged underneath, which is even Fibers spread out across the width with the well-known scratches Tear rollers 3 passes.
  • the following endless belt 4 passes the laid nonwoven to the endless belt 5, which is initially only shown in principle Water needling device 6 runs for solidification. There is also needling here conceivable on drums, as described in DE-A-197 06 610.
