Definitions

  • the invention relates to a metal fabric for the depth filtration of fluids and a method for producing such.
  • the task is regularly to process fiber yarns together or with other materials to a microstructure, for example, to a fabric, mesh, knitted fabric or knit.
  • Fiber yarns are usually present as thread-like products made by capillary fiber spinning.
  • the capillary fibers can be a bundle of extremely long spun fibers; However, they can also be cracked or shortened and processed into a yarn, for example, twisted be.
  • fiber yarns are made of many twisted capillary fibers, and fiber yarns having different properties can be produced by the capillary fiber diameter, the capillary fiber length, and the type of twisting or aftertreatment of the yarn.
  • the fiber yarns are often difficult to process. Due to their multifilament structure made up of a large number of independent capillary fibers, the fiber yarns sometimes have only a small cohesion.
  • the ends of the capillary fibers may protrude from the fiber yarn.
  • the capillary fibers can spread and thereby increase the diameter of the fiber yarn.
  • individual capillary fibers can thereby strip along warp threads or the weaving device and thereby be damaged, resulting in a structural weakening of the fiber yarn.
  • the EP 0 432 439 A2 shows a thread for producing a technical fabric, knitted fabric or the like.
  • This patent application processes staple fibers. These are characterized by the fact that each fiber is relatively short in itself. Also, the patent application emphasizes that the use of continuous fibers is problematic.
  • the EP 0 432 439 A2 therefore uses short fibers as part of its inventive teaching. These are held together by a binding thread to give a workable thread. Without the wrapping thread, the thread will disintegrate at the slightest touch into thousands of short pieces of staple fiber.
  • the Umwindefaden is dissolvable, in particular chemically dissolvable or thermally dissolvable. Once the tissue is made, the EP 0 432 439 A2 in that the wrapping thread is dissolved and thus disappears from the tissue.
  • the DE 31 26 051 A1 suggests a carpet yarn. This should be as fluffy as possible.
  • at least one of two basic threads should consist of endless capillary fibers.
  • the production of the multi-component yarn is carried out in such a way that in one operation of two or more of Endloskapillarmaschinen existing Basic threads of a very high speed of a rotating hollow spindle is supplied and thereby evenly wound by a very thin Umwindefaden and finally wound in this form continuously at high speed.
  • the invention is based on the object to reduce the difficulties described in the processing of polyfilem fiber yarn as far as possible or even to eliminate from the world.
  • the winding thread is preferably a long thread which runs around all capillary fibers of the fiber yarn. Through the winding thread, the capillary fibers are held together so that they retain their cohesion even under different force, but at least under their own weight.
  • the winding thread can even be a bias exert on the capillary fibers, wherein the bias can act both in the radial direction of the fiber yarn or even in its longitudinal direction.
  • the fiber yarn is easier to process. This applies both to the manufacturer of the fiber yarn and to the one who processes the fiber yarn into a microstructure.
  • the wrapping according to the invention with a winding thread brings great advantages in particular when the capillary fibers are intrinsically stiff.
  • Self-stiff capillary fibers are understood as meaning capillary fibers which have a buckling load of at least 0.01 N in a vertical, one-sided restraint with a cantilever length of 1 mm.
  • the degree of inherent rigidity is predominantly determined by the material of the capillary fiber and by its geometry in cross section.
  • Intrinsically stiff fibers can absorb a not inconsiderable buckling load, so that special problems can arise when processing a fiber yarn with a cantilevered inherently stiff capillary fiber. For example, when weaving a fiber yarn having such a projecting capillary fiber end on the weft yarn, the warp yarns may be easily damaged. Under certain circumstances, the weft can even get caught and stuck.
  • Intrinsically stiff capillary fibers can also be held together particularly well with a winding thread according to the invention. This is especially true because the capillary fibers are at least predominantly metallic.
  • a comparable enrichment brings the invention even if the capillary fibers have a diameter of less than 100 microns, preferably less than 30 microns.
  • a fiber yarn composed of capillary fibers of such fineness often has flaws because such fine capillary fibers are very vulnerable. In particular, they can be rapidly cracked or otherwise severed so that the described problems can easily occur in conventional fiber yarn processing.
  • the winding thread has a different structure than the capillary fibers.
  • structure is understood to mean, in particular, the material, but also the thickness of the winding thread or its cross-sectional shape can be designed differently. For example, when processing a fiber yarn with very high-quality capillary fibers, a cost-effective winding thread can also be used under many circumstances.
  • winding thread In general, it is desirable in most cases that the most cost-effective, safely processed winding thread is used. This can be ensured, for example, that the winding thread is monofilament. A monofilament thread can be processed very reliably.
  • the winding thread is metal.
  • it may consist of two twisted metal fibers or of a metal wire.
  • the winding thread has a lower physical and / or chemical resistance than the capillary fibers. This makes it possible in particular to remove the winding thread after introduction of the fiber yarn into the structure.
  • the winding thread may be made of plastic, while the capillary fibers are made of metal; then the winding thread can be melted away or etched away after insertion.
  • the capillary fibers and / or the winding thread made of stainless steel.
  • the winding thread can advantageously have a rise height between 7 mm and 1000 mm.
  • Extensive experiments with a wide variety of capillary fibers have shown that most fiber yarns solve the underlying task to a particularly high degree when they are so wound.
  • the fiber yarn has a second winding thread, which preferably rotates the fiber yarn in opposite directions to the first winding thread.
  • a high strength of the capillary fibers can be achieved not only with a high rise height of the winding thread or the winding threads. Rather, the reliability is also significantly increased because the fiber yarn does not or only partially loses its strength even when tearing a winding thread.
  • even more than two outgoing number of winding threads implement the basic idea of the invention.
  • this can be used, for example, plastic winding threads, which are thermally or chemically released from the structure.
  • Another possibility is, for example, that grasped and / or held on both sides of the structure of the winding thread and torn by applying a tensile force.
  • grasped and / or held on both sides of the structure of the winding thread and torn by applying a tensile force Especially with a large rise height of the winding thread, it even offers to take the winding thread on one side of the structure and simply pull out. The removal of the winding thread can take place at any time between the introduction of the respective fiber yarn and the completion of the structure.
  • This proposed method achieves a particularly great advantage when the structure to be produced is a woven fabric and the fiber yarn is introduced as a weft thread.
  • the fiber yarn can be protected thereby introduced into the tissue and ideally has no kinks that can partially compress the yarn excessively.
  • the wound fiber yarn forms a relatively smooth surface that facilitates the weaving process.
  • the fiber yarn 1 in the figure consists in its basic structure of a plurality of capillary fibers with a very small diameter (represented in the figure as a plurality of bundles and exemplified by 2a, 2b, 2c).
  • the number of capillary fibers 2a, 2b, 2c is over 500, each capillary fiber 2a, 2b, 2c has a diameter of less than 20 microns.
  • the capillary fibers 2a, 2b, 2c are arranged along the fiber yarn 1 at only a slight angle to each other and spun together, but have only a smaller cohesion, especially in edge regions and in some areas tend to spread, especially at a bend of the fiber yarn 1.
  • the clockwise metal wire 3 and the left-handed metal wire 4 are wound around the capillary fibers 2a, 2b, 2c.
  • the two metal wires 3, 4 have the same structure: their diameter is 0.03 mm and they rotate the capillary fibers 2a, 2b, 2c with approximately 70 turns per running meter of the fiber yarn 1 along a yarn direction 5.
  • the left-hand metal wire 4 thereby orbits both the Kapillarmaschinen 2a, 2b, 2c and the right-hand metal wire 3. At crossings (exemplified by 6) is therefore the left-hand metal wire 4 outside on the clockwise metal wire 3.
