Definitions

  • the invention relates to a method for producing a conductive connection between Thread material made of a conductive core, preferably a carbon fiber core, and an insulating Sheath layer, as well as the production of a thermally conductive fabric from one endless thread product with a conductive core and an insulating jacket layer, preferably a continuous material produced in warp and weft arrangement and the use of this fabric.
  • the object of the invention is therefore a method for producing a conductive connection between thread material from a conductive core, preferably a carbon fiber core, and to create an insulating cladding layer, which in particular for further processing in a fabric created from the thread material is suitable and the known disadvantages avoids conventional connections.
  • the insulating jacket layers are opened with a solvent.
  • the cladding layers are opened as well the pressing of the conductive cores by simultaneous application of pressure and heat in the Contact area of the thread material to be connected.
  • the cladding layers opened by the action of heat and high pressure and thus a conductive contact made between the conductive cores.
  • An insulating layer is preferably sprayed on. This creates a smooth finish and a similar surface.
  • the material opened under heat and pressure closes after the heat supply has ended completely by itself.
  • the invention also relates to the production of a thermally conductive fabric from an endless Thread product with a conductive core and an insulating jacket layer.
  • the object of the invention is to create tissue which avoids these disadvantages and allows a controlled heat distribution.
  • the invention solves the problem in that the outline of the fabric by a self-contained Line shorting is defined by making further line shortings line clusters arise within the chosen outline, and that the tissue outside the defined short circuit is separated from the continuous material.
  • the piece of fabric which can be freely selected in terms of its shape is thus removed from the material web for the time being Establishing a closed line connection that corresponds to the circumference of the piece of tissue separated from the dressing and then mechanically applied.
  • the mechanical Disconnection takes place outside of this in order not to violate the line short.
  • the invention provides in a further development that the The lines are marked using a grid.
  • the grid corresponds an optically generated computer grid.
  • the line connection can be easily established along this path thus drawn.
  • the invention provides that the tissue separated from the continuous material is connected to a controllable power source via further line closures and that in addition to already specified line areas, cross-connections for the arbitrary arrangement of conductive areas with individually selectable expansion take place by selective supply of pressure and heat.
  • the invention further provides the use of a fabric made in accordance with the invention by introducing the conductive fabric into material webs for the production of clothing, Accessories, therapeutic materials, healing aids and materials for first aid in front.
  • thermoplastic as continuous filament material 3 in section.
  • the material thickness of the thermoplastic used as the insulating cladding layer 2 is between 2 and 5 ⁇ m. With this layer thickness, the continuous thread material is not too stiff to be further processed to be able to. The fiber accumulates during coating, which is simultaneous is advantageous.
  • a conductive core preferably a carbon fiber core, and an insulating Sheath layer of existing thread material, which is in the form of yarns, beds, ribbons or wires can be conductively connected with another equivalent thread material, the method steps shown in Fig. 2 are necessary.
  • the thread material 3a, 3b is arranged crossed over. Then takes place in the intersection area 4 the simultaneous opening of the cladding layers 2a, 2b of both threads 3a, 3b.
  • this step is carried out by the punctual application of a suitable one Solvent 5.
  • a suitable one Solvent 5 As a result, the sheath layer on both threads is detached and the Fiber cores 1a, 1b can touch each other.
  • the two cores are then pressed.
  • the cores are pressed, as shown in FIG. 2c, with the help of a plunger 6.
  • the wires to be pressed are at least in their Crossing point on a base 7 that supports the pressing.
  • 2c shows an embodiment in which the additional insulating material is fed through an opening 8 in the plunger 6.
  • the insulating material Due to the heat and high pressure, the insulating material is pressed open in the crossing area and thus there can still be a conductive contact between the units to be connected be made easier.
  • a variant of the variant described above results when using a special property comprising material for the insulating cladding layer.
  • This material flows apart when pressure and heat are applied and gives the crossing area so free.
  • the line nodes produced in this way are used in particular in the manufacture a thermally conductive fabric. This is made from filaments and preferably too a mat or an endless material.
  • This fabric should now be embedded in material webs, preferably made of natural or synthetic fibers for the production of clothing, therapeutic bandages or corsages etc, as well First aid materials find their use.
  • the purpose of the application is to heat the tissue in all cases.
  • the material 9 to be processed is removed from the mat 10 in accordance with its shape (Fig. 4a). A self-contained line connection is established along the outline. Outside of this, the material is mechanically separated.
  • the separation can also be carried out by applying pressure and heat by a cutting roller, here a cutting edge 11 and a pressure roller 12, (Fig.4b) this both steps take place simultaneously.
  • a cutting roller here a cutting edge 11 and a pressure roller 12, (Fig.4b) this both steps take place simultaneously.
  • Line clusters can also be created within the selected forms.
  • FIG. 4c one works with templates 13.
  • these templates 13 are produced with the aid of a computer and applied to the material to be processed, for example by means of light.
  • a coordinate system 14 is used here.
  • the halftone dots can be just as good from the computer's memory to a tool are directed, which exactly generates the given clusters.
  • heat patterns can be created produce. Short distances result in low temperatures, high distances result in high temperatures.
  • the external and controllable power source is also connected using the method for Connection between the thread material.
  • the conductive core is a carbon fiber, copper or silver core. That is just for elasticity significant.
  • connection points The use of a soldered connection would - at least the advantages of the heatable tissue at the connection points - destroy. Because just the extra and excess Material accumulation at the connection points would be especially in clothing, but also very annoying with heat compresses and bandages of a general kind.
  • 6 a, b shows an annular insert in an elastic bandage 15, for example warming tissue is sewn into it.
  • the transition 16a, 16b takes place in the edge zones on a fine insulated silver band 17, which leads to the battery holder 18.
  • the battery can For example, be attached to the waistband.
  • the zones to be heated can be precisely aligned.
  • a fabric designed in this way also requires only low energy consumption.
  • Tissue with a carbon core can also be processed afterwards. you can therefore also be used for the piece that has already been manufactured - or already in use standing - add additional heat patterns.
  • the tissue is primarily used in the therapeutic field.
  • the material is also used for emergency blankets, especially for mountain rescue.
  • the ceiling can already be used with the external battery for a known purpose be preheated to a specified temperature in good time.
