Definitions

  • the invention relates to a device for producing a web of material solidified by water jet treatment and / or structured, consisting of a nonwoven or knitted fabric of synthetic staple fibers, natural fibers, continuous fibers or mixtures of said fibers.
  • the object of the present invention is to develop a device which can be used both for structuring a material web and for solidifying it.
  • This task can be solved by different shrink sieves, which are shrunk as an endless tube on a perforated drum.
  • shrink sieves two completely different functions of the device according to the invention can be fulfilled namely, a structuring of the web and, on the other hand, its consolidation.
  • the invention therefore relates to an apparatus for producing a fabric web which is solidified by water jet treatment and / or structured, consisting of a nonwoven or a knitted fabric of synthetic fibers, natural fibers, continuous fibers or mixtures of said fibers, in which a coarse lower wire 2 is provided on a perforated drum 1 and above a finer shrink sieve 3 are arranged and the shrink sieve consists of a sieve belt, which is shrunk in an endless tube.
  • coarse shrink sieves are used which have about 5 wires / cm (warp and weft).
  • a previously solidified nonwoven fabric is provided with a textile structure in such a way that the structures run in the direction of travel and at right angles to it. This is achieved by a coarse shrink sieve whose shrinkable warp threads are orthogonal around the drum and whose non-shrinking weft threads are arranged axially parallel to the drum.
  • the structuring thus carried out can also with heavy goods, which has more than 100 g / m 2 , be worked because a rebound effect of the water jets used in the needling does not occur and is not required, since heavy nonwovens for the high-energy water jets a barrier represent and thus prevent a "shooting through”. A solidification of the web is not achieved in the structuring thus carried out, so that the web must have previously received its strength.
  • the shrink screen used for structuring is used as the last belt in the system, since after structuring no further needling can be used more. Any further needling would destroy the structure created again.
  • a Endabsaugschlitz is provided, the best way dewatering the wet web to drive the goods with a defined residual moisture in the subsequent drying process or other follow-up processes.
  • a further possible application of the device according to the invention is that a shrinkage screen applied to the perforated drum can also be replaced as a substitute for the microporous shell previously used for solidifying a light nonwoven (basis weight less than 100 g / m 2 ).
  • the hole drum When using an MPS, the hole drum must be manufactured with tight tolerances, since the MPS must be pushed onto the drum with little play so that it is not damaged by increased flexing during operation. For example, if it were possible to replace the MPS with a shrink sieve, the load bearing punch drum could be made to greater tolerances since a shrink wire can accommodate larger diameter differences in the drum.
  • a shrink screen requires significantly less investment cost than an MPS and a damaged or worn shrink screen can be relatively easily replaced, whereas a new MPS due to the tolerance field is supplied with a different diameter and most likely will not fit as well on the drum as before used MPS:
  • the kinetic energy of the water jets is now used to change the position of the individual fibers and thus to increase the strength of the previously loose fiber structure.
  • This is according to the invention light nonwovens achieved in that on the drum 3, a very fine shrinkage screen is mounted and the fine structure, a homogeneous surface can be achieved at which a water jet rebounds again.
  • the water jets hitting the fleece at high speed pass through this, then hit the shrink sieve 3 and from there are thrown back against the fleece.
  • the occurring rebound effect causes the fleece is now also needled from the bottom and thus significantly higher strengths are achieved.
  • the shrinkable screen belts In the screen belts used in the device according to the invention, open surfaces are provided for discharging the liquid sprayed from the many outlet openings of a nozzle beam at high pressure.
  • the shrinkable screen belts contain warp and weft threads, which may consist of thermoplastic homo- or copolymers. However, it is particularly advantageous if the shrinkable screen belt contains weft threads, which consist of metal wire.
  • a device may be particularly advantageous in which a further sieve is inserted between the coarse lower sieve 2 and the shrink sieve 3 so that a total of three sieves are superimposed on the perforated drum 1. This is particularly advisable for large differences in the mesh size and / or the wire thickness of the bottom wire and the shrink screen.
  • a strength of 93 N in the machine direction and a strength of 20 N in the transverse direction is achieved with a nonwoven thickness of 0.72 mm.
  • FIG. 1 shows schematically the structure of the drum.
  • the lowermost layer forms the perforated drum 1.
  • the layer structure is closed at the top by the shrink sieve 3.
