Definitions

  • the invention relates to a method of air texturizing or air entangling of hybrid filament yarns, a product of the method and a application of the product in accordance with the introductory portion of the independent claims.
  • multifilament yarns In all cases the air techniques are only applied to multifilament yarns of a synthetic or natural man-made fibre. Contrary to monofilament yarns, multifilament yarns consist of a plurality of single endless fibres or filaments. Thereby, air treated multicomponent yarns are built up exclusively from multifilament yarns, because it has been a general believe that a reliable combining of the components, i.e. of the multifilament yarns can be obtained only if each component is opened by the air flow and the individual filaments of all components interlace or entangle.
  • the invention makes reference to a prior art according to the U.S. Pat. No. 4,406,310.
  • a monofilament yarn is processed together with at least one multifilament yarn by a air treatment of the kind mentioned above to a multicomponent yarn.
  • a monofilament yarn of a medium or high weight or denier value, possibly reinforced by a multifilament yarn is air jet texturized as stationary thread together with a multifilament yarn with filaments of a low weight or denier value as fancy thread. Due to the relatively heavy mono-filament-stationary thread a multicomponent yarn of a high strength for a meaving into a carpet base fabric is obtained.
  • the multifilament-fancy thread must, however, include filaments which are as light as possible.
  • a use of the monofilament yarn as fancy thread is not taken into consideration. Instead of that it was a general believe that a sufficient looping and a appealing yarn texturizing in the air flow is possible only by a supplying and opening of the at least one multifilament fancy thread by this method exclusively man-made fibres are air treated.
  • the EP 344 650 discloses a method in which a main fibre bundle with an accompanying fibre bundle are air entangled in such a manner that the main fibre bundle is opened only partly and is penetrated by fibres of the accompanying fibre bundle.
  • a method of producing a glass fibre cable with metal cores for bullet-proof or flame-resistant textile fabrics is disclosed.
  • the glass fibres of least one metal core and possibly synthetic man-made fibres are led together without any overfeed, subjected to a air flow treatment for an opening at low air pressures.
  • a loose compound of filaments with a high total weight of 3000 dtex-96000 dtex is arrived at.
  • the metal portion can vary between 20% and 80%.
  • the metal cores remain to a large extent not influenced by the air flow treatment and serve predominantly for an increase of the tensile strength of the textile fabric cable.
  • the low pressure air treatment zone can be accomplished without a conventional texturizing apparatus and be integrated in the normal winding process between creel and reeling apparatus.
  • the deflection panels used often in the conventional process for a multiple deflecting and improved texturizing of the thread are not present. Such deflection panels are considered rather to be a substantial obstacle for a incorporating metal filaments in air treatment processes.
  • the FR 2 730 507 discloses a similar method. In this, however, the effect yarn is delivered with an overfeed.
  • the invention has as object to provide a simple production method for improved multicomonent yarns, a improved multicomponent yarn and a new application of the multicomponent yarn. This object is met in accordance with the invention by the features of the independent claims.
  • At least one multifilament yarn and at least one monofilament yarn are delivered in a air jet texturizing or air entangling process from at least on filament delivery apparatus to a pressurized air nozzle and are combined thereat by a air jet texturizing or air entangling to a multicomponent yarn, whereby at least a first monofilament yarn of the monofilament yarn is metalliferous and electrically conductive and is air jet texturized or air entangled with the at least one multifilament yarn.
  • a metal or metalliferous monofilament yarn is processed into a multiple component yarn according to a method for a air jet texturizing or air entangling as disclosed for instance in the PE 0 696 331 B1.
  • a reliable bond of the metalliferous monofilament yarn with the multifilament yarn is achieved in that the multifilament yarn is opened by the air flow and the individual filaments interlace with the depending from the overfeed more or less bent and loop forming metal containing monofilament yarn.
  • Such a multifilament-metalmonofilament hybrid yarn has exceptionally large advantages and allows completely new applications.
  • the hybrid yarn possesses due to the intensive, specifically loop forming air treatment a high quality textile structure such as is expected from a texturized textile fibre, such as e.g. larger volume and voluminosity, increased mechanical strength and elasticity, improved moisture absorbing quality and much more.
  • the hybrid yarn and textile fabric product from same can be washed, colored and printed and possess a extraordinary high resistance against rubbing.
  • the main field of application of such textile fabrics is the production of electromagnetic shields with quite favorable attenuation properties and possibly large areas.
  • a further advantage for all applications consists in the low specific weight of the hybrid yarn according to the invention and textile fabrics produced from same. Typical surface area weights are in the range of 150 g/m 2 -450 g/m 2 .
  • the first monofilament yarn is a metal thread and specifically a metal strand.
  • the metal strand has hereby a monofilament character because it is not opened by the air treatment and is rather bent and looped as single filament. Because the metal monofilament yarn is not opened up by the air treatment it is possible to produce from the hybrid yarn lightweight electrically conductive textile fabrics for technical applications, coverings of rooms, garments and similar as a protection against a electrostatic charge and electromagnetic radiation.
  • a further field of application for air flow texturized or air entangled metal monofilament-multifilament hybrid yarns is the production of electrically heatable coating materials, e.g. for motor vehicle seats, furniture or wall heaters.
