Definitions

  • WO 97/30223 makes known an air-lay method for producing a composite non-woven fabric, where a plurality of air-lay moulding heads of the type according to EP 0 032 772 are disposed one behind the other and produce a composite non-woven fabric from connecting fibres, then cellulose fibres and again connecting fibres.
  • This type of production has the advantage of higher achievable speed compared to the formation of card non-woven fabric.
  • a calender and a through-ventilation unit are connected and the object of these is to attach the connecting fibres to one another using heat.
  • the object of the invention is to find a method, the fibres from which should make up this type of non-woven fabric for the air-lay method and subsequently to find how this fabric should be strengthened to prevent, amongst other things, delaminating.
  • the multilayered composite non-woven fabric comprises two outer layers, which are formed according to the air-lay method from fusion adhesive fibres, such as more especially double-component fibres or and other fibres, such a high polymer fibres, between which layers is placed another layer of super-absorbent pulp, also produced solely according to the air-lay method, and whereby this composite non-woven fabric, which is produced solely according to the air-lay method, is subsequently strengthened by means of the hydrodynamic needling process.
  • This type of non-woven fabric composition for the surface layers and the type of strengthening by means of the water needling process guarantees a surface which is free of pilling and linting, but which, nevertheless, is porous to liquid and can also cover a stronger, absorbent pulp layer.
  • the two outer layers of this type of non-woven fabric are intensively strengthened by the water needling process and are also bonded to the pulp layer, which is what the dreaded laminating of the fibre types after strengthening prevents.
  • both the layers are preferably treated with the water needling process, that is to say the composite non-woven fabric is needled on both sides.
  • the fusion adhesive fibres should be treated for further bonding on each other and to each other by means of heat.
  • the heat also influences the required surface finish of the non-woven fabric.
  • the double-component fibre is particularly advantageous because it remains preserved as original fibre during the heat treatment, whilst the normal fusion adhesive fibre can fuse and shrink, which is disadvantageous for the forming of the resistant surface.
  • This measure of heating the fusion adhesive fibres is already known through U.S. Pat. No. 5,240,764, however not in conjunction with the double-component fibres.
  • the heat treatment can be effected in the most varied way; the essential point is the fibres bonding well on the surface and transversely through the surface non-woven fabric.
  • a device of the type according to the invention is represented as an example in the drawing. Further inventive details can be explained by way of this example. In which:
  • FIG. 1 is the side view of a continuous system for the production and strengthening of a dry non-woven fabric, which has been laid according to the air-lay method, and
  • FIG. 2 is a system similar to FIG. 1 with no thermo bonding according to the lay method.
  • the non-woven fabric is initially formed from staple fibres and pulp.
  • the staple fibres must be cut short enough for them to be laid according to the air-lay method, i.e. they are from 8 to 10 mm maximum in length.
  • the moulding head 1 is then charged with the staple fibres for the base layer of the non-woven fabric.
  • the staple fibres are such that they can be brought to adhesion under the influence of heat. More especially advantageous here are double-component fibres, which have the advantage that they do not shrink under the influence of heat, but remain preserved as fibre.
  • the non-woven fabric 4 is first pre-strengthened by means of heat in the device 5 .
  • This can be effected by means of hot air (through-ventilation), but also with the application of infrared radiation or with calendering.
  • This pre-strengthening measure has the advantage of obtaining better surface closure of the surface layers, which can prevent a greater loss of pulp during the subsequent needling process.
  • the system shown in FIG. 2 does not have this pre-strengthening under heat. Therefore, depending on the fibre and other conditions, the pre-strengthening measure can be left out.
  • the composite non-woven fabric 4 is then acted upon by the hydrodynamic needling process.
  • a non-woven fabric with surface layers on both sides it is expedient to execute the strengthening process with the water jets on both sides.
  • the needling arrangement is represented in the Figures with two drums 6 and 7 , which is only to indicate that the non-woven fabric is to be conveyed in a meander-shaped manner about the drums so that it can be acted upon on both sides by the water jets.
  • This water jet strengthening process not only influences the surface of the composite non-woven fabric, but also the deeper cohesive strength of the layers such that a subsequent delaminating of the individual non-woven fabric layers no longer occurs.
  • the non-woven fabric After the strengthening of the composite non-woven fabric and also the bonding of the layers with each other by means of the water jets, the non-woven fabric must be dried.
  • a through-ventilation drier 8 such as a sieve drum drier, is advantageously advantageous.
  • the non-woven fabric can be calibrated again by means of the arrangement 9 , as is only represented in the system shown in FIG. 2.
  • This type of composite non-woven fabric is very economical because it can be produced at high speeds, such as, for example, 400-500 m/min.
  • a very absorbent product of 40-100 g/m 2 can be produced, as the pulp layer can be thick.
  • the surface layers should be thin in relation to the pulp layer, for example 10 gm 2 , whilst the pulp layer can be heavy at 60 g/m 2 .
  • the surface is not only essentially free of linting and pilling, but the non-woven fabric is also strengthened through and through and this makes it difficult to separate the layers of the non-woven fabric.
