Definitions

  • the present invention relates to an electrically conductive yarn having a multifilament core comprising a plurality of electrically conductive filaments, and a wrapping arranged around the multifilament core.
  • LED packages are available as surface mounted devices (SMD), which can be attached to the fabric by gluing, snap button connection or stitching.
  • SMD surface mounted devices
  • conductive yarns which may be either woven, knitted or embroidered into the fabrics and/or non-vowen structures.
  • Such conductive yarns may for instance be formed of metal, such as stainless steel, and be twisted with non-metallic yarns and fibers. Weaving and embroidery, however, impose mechanical requirements on the conductive yarns, and for weaving, the best results are usually obtained using textile-like materials, such as polyester or polyamide. Therefore, the conductive yarn may also be formed of a plurality of non-conductive filaments, each coated with a conductive metal layer.
  • Textiles utilized for electronic applications usually comprise a plurality of these conductive yarns, provided across the fabric.
  • the presence of several conductive yarns close to one another might, however, pose a problem. Failing in keeping the conductive yarns separated over time may viz results in short circuiting between adjacent conductive yarns, thus causing the electronic application to malfunction.
  • an electrically conductive yarn having a multifilament core comprising a plurality of electrically conductive filaments, and a wrapping arranged around the multifilament core.
  • the wrapping is arranged to partly expose the multifilament core, thereby reducing an occurrence of short-circuiting between adjacent electrically conductive yarns while enabling electrical connection of electronic components to the multifilament core.
  • the invention likewise concerns a method of manufacturing an electrically conductive yarn of the kind defined above.
  • a method of manufacturing an electrically conductive yarn having a multifilament core comprising a plurality of electrically conductive filaments comprises the step of arranging a wrapping around the multifilament core such that the multifilament core is partly exposed, thereby reducing an occurrence of short-circuiting between adjacent electrically conductive yarns while enabling electrical connection of electronic components to the multifilament core.
  • An electrically conductive yarn may comprise a plurality of conductive filaments, perhaps as many as 50-300. It is however likely that some of the filaments, by for instance tear, are worn off somewhere along the conductive yarn during production or use. These worn off filaments are prone to protrude from the conductive yarn, and as textiles utilized for electronic applications usually comprise a plurality of conductive yarns provided across the fabric, filaments sticking out from a conductive yarn may, as discussed in the foregoing, pose a problem with regards to possible short circuiting with adjacent conductive yarns.
  • the inventors have realized that by preventing the filaments in a conductive yarn from separating, this can be avoided.
  • a wrapping in accordance with the present invention i.e. arranging a wrapping around a multifilament core leaving the multifilament core partly exposed, the risk of short-circuiting between adjacent conductive yarns is reduced.
  • the wrapping which formation preferably is consistent throughout the length of the multifilament core, partly encloses the core, thereby preventing worn off filaments from protruding from the core and getting in contact with adjacent yarns. Since the wrapping leaves the multifilament core partly exposed, electrical connection of electronic components to the multifilament core is, however, yet possible.
  • Electronic components such as LEDs
  • the multifilament core although the wrapping encloses the core.
  • the ability to connect electronic components directly to the core is advantageous, as the core comprises a plurality of conductive filaments, thereby providing good conductivity. Consequently, textiles comprising electrically conductive yarns in accordance with the present invention enable for electronic textile applications to be realized, while short-circuiting between adjacent conductive yarns is prevented.
  • the wrapping partly protects the filaments from wear, as the wrapping limits the effects caused by exposure to air, moisture, chemicals and more importantly abration from rubbing the conductive surfaces against other objects, including other textile yarns, during production, usage and care. That is to say, the wrapping contributes to preventing filaments from being worn off, and the conductive yarn according to the present invention subsequently contributes to avoiding decreased conductivity.
  • envelope surface of the multifilament core is, in the context of this application, to be understood in a broad sense, meaning the surface area of the core in its longitudinal direction.
  • the uncovered portion enables electrical components to be connected to the multifilament core, while the covered portion prevents filaments from becoming separated.
  • the formation of the wrapping may differ from one conductive yarn to another, so may the ratio between the covered and uncovered portions of the envelope.
  • the electrically conductive filaments may preferably be provided throughout the core of the electrically conductive yarn, from a center to a perimeter thereof. Arranging the filaments in this manner, they will provide good conductivity and textile characteristics.
  • the electrically conductive filaments may each comprise a non-conductive filament, for instance a polyamide or polyester filament, provided with a conductive coating.
  • the thin conductive layer does not significantly change the thread properties.
  • the conductive coating may preferably be a metal coating, for instance silver, thin enough to be undamaged in the textile processing. The choice of the metal content further determines the conductivity of the filament.
  • the wrapping may comprise a wrapping yarn, which is wound around the multifilament core in a first winding direction to form a single spiral structure.
  • a period of the spiral is greater than twice, and smaller than six times a diameter of the wrapping yarn.
  • the wrapping may comprise a further wrapping yarn wound around the multifilament core in a second winding direction, opposite the first winding direction, thereby forming a double spiral structure.
  • Providing a double spiral structure in this manner enables, for instance, use of a thinner wrapping yarn than is possible for the embodiment utilizing a single spiral wrapping structure.
  • the double spiral structure presents a more homogeneous conductive yarn, i.e. more isotropic, thus easier to weave.
  • a diameter of the wrapping yarn is smaller than a diameter of the multifilament core, preferably smaller than 75% thereof.
  • the wrapping yarn may be a staple yarn, as well as a monofilament or a multifilament yarn.
  • the wrapping of an electrically conductive yarn in accordance with the present invention may be arranged to form a net structure around the multifilament core.
  • the open net structure leaves the multifilament core easily accessible, and the wrapping according to this embodiment likewise enables electrical components to be connected to the multifilament core while protrusion of worn off filaments through the wrapping is prevented.
  • the wrapping is electrically conductive.
  • Utilizing a conductive wrapping facilitates the connection of electrical components, as the possibility of connection is not restricted to the conductive multifilament core, but extended also to include the conductive wrapping.
  • a conductive wrapping further increases the overall conductivity.
  • the wrapping may likewise be non-conductive.
  • a non- conductive wrapping has the advantage that it is robust upon soft forces such as wrinkling, that is to say, the wrapping contributes to avoidance of shortcircuiting between conductive yarns during wrinkling.
  • Connection of electronic components to the multifilament core can be made by pushing the non-conductive wrapping aside at the points where attachment of components is required.
  • the multifilament core is preferably twisted. Twisting further locks the structure, which enhances yarn strength as well as prevents worn off filaments from protruding from the structure. Twisting also increases the contact area between single filaments, which can enhance conductivity.
  • the level of twist should be determined based on desired strength, conductivity, bending rigidity, etc. of the complete yarn structure.
  • arranging the wrapping around the multifilament core may include providing a preformed wrapping around the multifilament core.
  • Providing a preformed wrapping may facilitate the manufacturing process, as the wrapping for instance can be thread upon the multifilament core during production of the conductive yarn.
  • the preformed wrapping may for instance be a knitted, open structured wrapping, adapted for partly enclosing the multifilament core.
  • the conductive yarn according to the present invention may, furthermore, advantageously be comprised in a fabric for connection of electronic components thereto.
  • the fabric according to the present invention may advantageously be comprised in an electronic textile comprising at least one electronic component connected thereto.
  • Fabrics comprising electrically conductive yarns in accordance with the present invention and electronic textiles comprising these fabrics consequently enable for electronic textile applications to be realized, while short-circuiting between adjacent conductive yarns is prevented.
  • fabrics comprising conductive yarns in accordance with the present invention and electronic textiles comprising these fabrics will, due to the wrapping protecting the core filaments from wear, prevent loss of functionality caused by worn off filaments and, subsequently, decreased conductivity.
