Definitions

  • the invention relates to a method for producing a in terms of strength and elongation in the longitudinal and transverse directions behaving approximately the same, i. isotropic Nonwoven fabric and a corresponding manufacturing plant.
  • nonwovens because of the fleece forming process, in particular the widespread carding method, a higher one prefers longitudinally orienting fibers Strength and lower elasticity in the laid fiber longitudinal direction own compared to the corresponding ones Values in the direction transverse to the preferred fiber layer.
  • This inequality the strength values in the longitudinal and transverse directions is independent of the type of solidification for all nonwovens So it's not just thermal solidified, but also in mechanically solidified Nonwovens, e.g. So with needle fleeces or at More nonwovens; in the latter case are at least one Side of the nonwoven fabric meshed the fibers.
  • the fibers are substantially transverse to the direction this nonwoven web oriented with the result that the Strength now higher in the transverse direction than in the longitudinal direction that is, non-uniformity - albeit in reverse Form - in principle persists.
  • Another, also in the field of nonwovens lying proposal according to DD 292 489 A5 uses several Fiber layers in nonwoven with differently oriented, parallel or transverse to the web edge running, intersecting fibers. And that is in the mentioned in the publication featured the nonwoven fabric from two separate Layers constructed, one of which is preferably longitudinally oriented fibers and the other preferably has transversely oriented fibers.
  • the different fiber layers are initially produced by separate web formers and are after the union to a common fleece of a mechanical Web stabilization supplied by meshing.
  • With such double-layered nonwovens can be isotropic nonwoven fabrics produce with high standing fiber content.
  • this method requires the requirement of two separate ones Laid former. Due to the required, considerable Investment costs are related to the area unit Cost price of the final product very expensive, so that the u.U. no longer competitive can be offered on the market.
  • the object of the invention is a method and a system for producing a nonwoven fabric, which relates to the longitudinal and the transverse direction is largely isotropic is, with the maximum strength values parallel or transverse be reached to the web page edge, which also at low Investment costs can be produced and which is solidify by any method.
  • a two-ply web of a single web forming device wherein the one Fiber layer mainly longitudinally oriented fibers and the other zig-zag shaped fiber layer predominantly across containing oriented fibers.
  • the zigzag-shaped fiber layer is deflected and combined with the other fiber layer.
  • Nonwovens Although it is in the manufacture of nonwovens for uniformity the local density across the surface of a nonwoven fabric known to unite several flores into a fleece, wherein at least one web forming means with two Fleece or several in line behind each other set up Fleece forming devices are used (see. the cited book publication "Nonwovens", page 157 f over web formation).

  • the invention relates to a system and a method for producing a multilayer isotropic nonwoven fabric, the in any way, preferably by meshing the near-surface Fibers, at least on one flat side mechanically is solidified, wherein at least one layer in the template fleece is provided with transverse oriented fibers.
  • the invention producible at low investment costs Nonwoven should be with respect to the longitudinal and the transverse direction behave largely isotropically, with the maximum strength values reached parallel or transverse to the web page edge become.
  • the multilayer full fleece 4 which is to be solidified into a nonwoven fabric exists from at least one partial web 5 with substantially longitudinally oriented fibers 3 'and another, from a Zig-zag-shaped pile existing cross-fiber part fleece 1 with substantially transverse oriented fibers 3, such as this perspective view in Figure 1 for a two-layer original fleece is shown. It is not of primary importance here whether the transverse oriented part fleece 1 or the longitudinal oriented part fleece 5 above or below in the full fleece 4 lies. This is more a question of the solidification process used and the later intended use of the Nonwoven.
  • the two partial webs in coarse Approximation with each other about the same basis weight. in the concrete case, however, depending on the used Solidification method and later use of the nonwoven fabric, a division of the fiber quantities of Nonwoven fabric on the two part webs 1 and 5 empirically choose.

  • the already mentioned ratio of the deceleration rates or the reciprocal v 2 / v 1 is therefore preferably two, three, four or five.
  • the two non-woven takers 11 and 12 running at different speeds must run at a fixed speed ratio corresponding to one of the stated values.
  • the higher the speed ratio v 2 / v 1 the lower the possible angle ⁇ between the zig-zag partials within the cross-fiber part batt 1, and the sooner the fibers 3 of the exit batt are actually transversely within the cross-fiber batt 1 oriented.
