Definitions

  • the invention relates to a nonwoven fabric, woven or knitted fabric consisting of metal fibers or filaments, which is to be consolidated or refined.
  • Metal fibers are produced, for example, by the bundle cold-drawing process (US Pat. No. 3,379,000), a machining process (peeling off the rolled edge of a metal foil roll according to US Pat. No. 4,930,199) or directly from the melt, for example by extrusion, as described in U.S. Pat. Patent 5524704.
  • Threads with homogeneous blends can be realized over the thread cross-section, but also the production of multi-thread wrapping yarns with metal fibers in the core and textile fibers in the jacket is practiced.
  • the disadvantage of all the mechanical consolidation processes mentioned is that the metal elements are subjected to high wear and tear, such as e.g. Knitting, knitting, felting needles, etc. They have to be replaced after a short period of use by new strengthening elements, which additionally incurs the costs for the wear material and the downtimes resulting from the replacement of the worn parts increase the manufacturing costs of a consolidated metal fiber nonwoven.
  • the invention is therefore based on the object to provide a nonwoven in which
  • Manufacturing the complicated labor and time-consuming thread forming process can be avoided, at least partially, preferably 100% metal fibers, without any textile carrier fibers, the wear of strengthening elements is reduced or completely eliminated, and thin fabrics with a high pore volume but small pore sizes can be realized.
  • This object is achieved in that a material web consisting at least partially of metal fibers or metal filaments is strengthened and / or refined by means of high-energy water jets into a ready-to-use material or the like.
  • the object is achieved by realizing high impact forces or impulse forces by using working medium pressures> 200 bar
  • a carrier tape or a perforated drum with an open area of 20 to 50%, or a screen covering or 20 to 100 mesh, preferably 60 mesh, for the removal of the solidification medium.
  • a thin, closed or patterned openwork spunlace nonwoven fabric is also made of 100% metal fibers, without the need for textile backing fibers, labor-intensive and time-consuming thread formation, a preparation to avoid static Charges and to ensure good fiber sliding properties between fiber / fiber, fiber / strengthening elements and
  • Fiber / transport organs is required and some wear occurs on the strengthening elements, as a strengthening agent
  • Example 1 The invention is explained in more detail in exemplary embodiments.
  • Example 1 The invention is explained in more detail in exemplary embodiments.
  • Example 1
  • a spunlace system consisting of 100% metal fibers and weighing 300 g / m 2 and aerodynamically formed is fed to the spunlace system.
  • the normal density of the alloy of the metal fibers was found to be 8 g / cm 3 .
  • the 12 ⁇ m thick, rustproof metal fibers are made of a chromium-iron alloy.
  • the metal fiber fleece is consolidated with high-energy water jets.
  • the water emerges from a nozzle plate with nozzles arranged in a row with a diameter of 0.14 mm, with a capillary density of 40 pieces / inch working width and under a process water pressure of 20 bar on the first nozzle bar and 300 bar on the second nozzle bar ,
  • These hardening parameters result in maximum tensile forces of 19 N in the longitudinal direction and 26 N in the transverse direction with a maximum tensile force expansion of 34% in the longitudinal direction and 53% in the transverse direction.
  • the arrangement and type of fleece corresponds to that of Example 1.
  • nozzle plates with nozzles of 0.10 mm in diameter and 40 pcs./inch working width are used.
  • the solidification medium is under a working pressure of 20 or 400 bar.
  • the metal fiber fleece consolidated under these parameters has maximum tensile forces of 24 N in the longitudinal direction and 32 N in the transverse direction with maximum tensile force strains of 31% in the longitudinal direction and 33% in the transverse direction.
  • the arrangement and type of fleece corresponds to that of Example 2.
  • 36 nozzles per inch working width are used.
  • the maximum tensile forces are 42 N in the longitudinal direction and 49 N in the transverse direction with maximum tensile force strains of 37% in the longitudinal direction and 43% in the transverse direction.
  • the spunlace nonwoven fabric of this example has completely identical force-elongation values in the initial and medium stress range for the longitudinal and transverse directions, i.e. it is absolutely isotropic there.
  • the porosity of the metal fiber nonwoven can be adjusted over a wide range by the choice of the consolidation parameters.
  • the pore volume is 97-99%. Depending on the process data, a pore volume of 60 to 99% can also be achieved.
  • Example 3 comes with three nozzle plates in corresponding nozzle bars Working pressure of 20/500/500 bar for use
  • the maximum tensile forces are 89 N in the longitudinal and 78 N in the transverse direction with maximum tensile force expansions of 29% in the longitudinal and 34% in the transverse direction. This example shows that a higher strength can be achieved in the longitudinal direction than in the transverse direction.
  • the arrangement and type of the nonwoven corresponds to that of example 3.
  • the consolidation process by high-energy water jets is followed by a pressing or calibration process.
  • the strength and the porosity of the metal fiber nonwoven can thus be influenced.
  • the metal fiber fleece to be consolidated is subjected to a spunlace treatment using 36 nozzles per inch working width with a diameter of 0.10 mm, a 20 mesh mesh sieve and a working medium pressure of 500 bar, and is perforated according to the pattern for use as a burner surface or the like ,
  • Embodiment 7 is a diagrammatic representation of Embodiment 7:
  • a metal wire mesh positioned between two metal fiber nonwovens with a mesh size of, for example, 10 ⁇ 10 mm is subjected to a spunlace treatment using 36 nozzles per inch working width with a diameter of 0.10 mm, a support screen of 60 mesh and a working medium pressure of 500 bar. This causes the nonwovens to solidify into a smooth surface with small pore openings while at the same time housing the metal mesh.
  • Such metal composites are used in filter tasks where high thermal loads occur. It has solidified Metal fiber fleece to perform the filtering tasks and the metal mesh to perform the function of the reinforcement.
  • nonwovens with a thickness between 1.5 and 3.4 mm were produced.
  • the bulk density was about 8 mm.
  • the density of the spunlace nonwovens was between 0.1 and 0.2 g / cm 3 .
  • the achievable porosity is between 60 to 99%.
  • the described nonwovens can be used, for example, in filter and burner technology, particularly where high thermal loads occur, in the EMC area, to implement explosion protection, etc.

Abstract

L'invention vise à soumettre un non-tissé consistant au moins en partie en fibres métalliques, à un processus de liage par piqûre ou de finissage superficiel, par aiguilletage hydrodynamique. La bande de matériau concernée peut être produite entièrement à partir de fibres métalliques ou à partir d'un mélange de fibres métalliques et de fibres textiles. La pression hydrodynamique de l'eau utilisée lors de l'aiguilletage dépend de la porosité recherchée après liage par piqûre.
