Definitions

  • the present invention relates to the field of textile yarns and the products in which yarns of this kind are used, in particular in the case of yarns that are electrically conductive and elastically stretchable.
  • Products of this kind are, for example, sheet-type heating elements such as those used for seat heating in the automotive field.
  • Yarns of this type are also used with floor coverings, blankets, heatable clothing or portions thereof and similar, and also shielding textiles to divert electric fields.
  • Textile electrical surfaces are used to adjust the temperature of environments that are in contact with the human body.
  • they are generally joined to other textile layers by stitching or gluing.
  • suitable heating conductors form surfaces comprising heating conductors and their supply lines.
  • the shape and size are adapted to match the applicable conditions of use.
  • metallic wires are very suitable for conducting current, they themselves possess few textile properties and this is a drawback when processing, such as weaving, knitting, etc. These wires are in this regard completely inelastic and do not have a textile handle.
  • a metallic wire is combined with a textile yarn or filament, generally by winding or twisting.
  • the combination comprising wire and elastic thread achieves a certain flexibility due to the elasticity of the textile filament.
  • the two elements already exist as individual filaments before the winding process and have to be manufactured in individual separate preliminary processes and are brought together by the winding process.
  • the metallic handle and the rigidity can only be influenced to a limited extent.
  • WO 2004/097089 A1 is an electrically conductive, elastic composite yarn comprising an elastic element.
  • This elastic element comprises one or more elastic filaments and is covered by at least one, but preferably a plurality of conductive filaments (longitudinal filaments).
  • Each conductive thread surrounding the elastic element has a length that is greater than the drafted length of the elastic element so that all of the elongating stress imposed on the composite yarn is carried by the elastic element.
  • This publication cites US-BS 6,341,504 . This mentions an elastic textile product which has a conductive wire for use in garments. This is intended for indicating physiological body functions.
  • This publication describes an elongated band of elastic material which is stretchable in the longitudinal direction and comprises at least one conductive wire either lying on or provided inside the elastic band.
  • DE 103 42 787 A1 discloses an electrically conductive yarn comprising at least one elastic core filament, at least one electrically conductive filament wound around the core filament and at least one non-conductive filament wound around the core filament which limits the stretch of the whole electrically conductive yarn.
  • a similar composite yarn is disclosed in DE 102 42 785 A1 and WO 2004/027132 A1 .
  • a technical problem (object) of the invention is to provide an electrically conductive, elastically stretchable hybrid yarn which is simple to manufacture and more effective with respect to electric conductivity and elastic stretch than the composite yarns known to date.
  • an electrically conductive, elastically stretchable hybrid yarn with an elastically stretchable core and an electrically conductive element assigned to the core on the circumferential side which permits the elastic stretch of the core, whereby the electrically conductive element comprises a fibre sheath surrounding the core at least partially and at least partially comprising electrically conductive fibres which are bonded with each other.
  • the core comprises at least one filament which is surrounded by the fibre sheath.
  • the at least one filament may comprise textured polyester or Lycra or a similar material.
  • a possible yarn number range is 2000-40 tex (Nm 0.5-25), whereby the fibres can have a fineness of 1.0-3.3 dtex and the fibres can have a cut length of 35-60 mm.
  • Conductive fibres such as carbon fibres, nickel-coated carbon fibres, metal fibres and fibres made of metal-coated polymers have no rigidity as individual fibres and, due to the fine titre, have extensively textile handle features.
  • fusible fibres can be mixed into slubbings or drawing slivers produced in a conventional preliminary spinning stage, preferably in an amount of 5-10%.
  • Thermal after-treatment of the elastic, conductive yarn which can, for example, be combined with a rewinding process or even take place at the same time as the subsequent textile finishing of the finished fabric, causes the fusible fibres to adopt a plastic state and after cooling bond the core filament and sheath fibres which can considerably improve the antislip properties of the hybrid yarn without noticeably reducing the electrical conductivity.
  • the hybrid filament is preferably produced using the so-called friction spinning method with which the fibres can be bonded with the core.
  • This friction spinning method was developed by the company Dr Fehrer Linz AG, the Dref2/Dref2000 System, which is familiar to a person skilled in the art.
  • the object is also achieved by a method for manufacturing a hybrid yarn by:
  • the heating can take place as thermal after-treatment of the elastic, conductive hybrid yarn, which can, for example, be combined with a rewinding process, or even during the subsequent textile finishing of the finished fabric.
  • the fusible fibres adopt a plastic state and after cooling bond the core filament and sheath fibres, which considerably improves the antislip properties of the hybrid yarn without noticeably reducing the electrical conductivity.
  • the object is also achieved by a textile product containing the aforementioned hybrid yarn.
  • Fig. 1 is a perspective view of a part of a hybrid yarn 3 in which a portion of the hybrid yarn in perspective view only shows the core filament 1, which here comprises a plurality of single filaments 4 which are bundled into a total core filament.
  • the core filament can also be embodied as a single filament.
  • This core filament is surrounded by a fibre sheath 2 comprising a plurality of short individual fibres 5.
  • the core filament 1 is an elastically stretchable filament which can, for example, comprise textured polyester or Lycra which is spun with conductive fibres.
  • the total yarn has, for example, a yarn count range of 2000-40 tex (Nm 0.5-25).
  • the fibre sheath is, for example, made of fibres with a fineness of 1.0-3.3 dtex and a cut length of 35-60 mm. To form the sheath, the fibres form a bond but this does not impair the elastic stretch of the core filament. This is even more applicable if, in a mixing process, fusible fibres are mixed into the sheath fibres, which are electrically conductive, for example in an amount of 5-10%. This serves to improve the bond between the elastic core filament and the conductive sheath fibres. These fusible fibres are, for example, mixed into the slubbings or drawing slivers produced in a normal preliminary spinning stage.
  • the sheath fibres can be conductive polyester fibres, high-grade steel fibres or metal and preferably silver or copper-coated polymers plus carbon fibres or nickel-plated carbon fibres.
  • the invention is based on the idea of spinning an elastic, textile filament such as, for example, textured polyester or Lycra with conductive fibres.
  • the elastic filament forms the heart or the core of the yarn and the conductive fibres, not as yet a finished filament, are themselves bonded with the core filament by means of a special spinning process.
  • a device such as that shown in Fig. 2.
  • the reference number 6 indicates the slubbings introduced, which are broken down into individual fibres by means of an opening cylinder 7.
  • Reference number 8 designates a guide roll for introducing the core filament and reference number 9 a drawing-off disc for removing the finished yarn in the region of a rinsing unit 10 with a dirt extractor 11 provided on its side.
  • the hybrid yarn 3 shown in Fig. 1 is manufactured with a device of this kind. It is possible to use the so-called friction spinning method developed by the company Dr Fehrer Linz AG, the Dref2/Dref2000 System, which is known to every person skilled in the art.
  • the slubbings are broken down into individual fibres and laid at right angles around the continuous core filament and friction-bonded therewith. This produces a homogeneous yarn with a high degree of elasticity, which in overall elasticity extensively corresponds to the elasticity of the elastic core filament.
  • the conductive fibres such as carbon fibres, nickel-coated carbon fibres, metal fibres or fibres made of metal with coated polymers have no rigidity as individual fibres and, due to their fine titre, have extensively textile handle features.
  • fusible fibres may be mixed into the slubbings or drawing slivers, which are produced in a conventional preliminary stage, in an amount of 5-10%.
  • Thermal after-treatment of the elastic, conductive yarn which can, for example, be combined with a rewinding process or even takes place at the same time as the subsequent textile finishing of the finished fabric, causes the fusible fibres to adopt a plastic state and, after cooling, bond the core filament and sheath fibres, which improves the antislip properties of the hybrid yarn without noticeably reducing the electrical conductivity.
