Definitions

  • the invention relates to a method for producing a current-conducting knitted fabric or knitted fabric for heating purposes according to the preamble of claim 1.
  • Such an electroconductive knitted fabric and manufacturing method are known from DE 201 00 915 known and will be after the DE 201 11 067 U1
  • the present applicant incorporated the carbon filaments by knitting into a base fabric or into relatively flat knit constructions. It is known to those skilled in the art that the production of flexible heating elements with the knitting or knitting machine in the surface is a rather complicated and problematic process, with the carbon filaments often undergoing breaks in the stitch forming process.
  • the invention is therefore based on the object to improve the aforementioned method for producing current-conductive knitted or crocheted so that it effectively prevents fractures in the carbon fibers in Strickverwirkesel and beyond a temperature-controlled heating, and an adjustable pressure stiffness with simultaneous thermal and electrical Isolation allows, so that the requirements of different applications can be met.
  • the carbon filaments do not experience any relevant damage in the surface formation, provided that some significant changes are made to the filament guide elements.
  • the latter can be described as follows:
  • the thread guide elements of the machine must be adapted to the low lateral force stability of the carbon threads.
  • the deflection members must therefore have no sharp edges or small deflection radii.
  • the surface quality and thus smoothness must be high or friction minimal.
  • the movement and dynamics of the needles for the meshing of the carbon threads as well as the needle movement of the other the carbon threads connecting threads and the binding technique is adapted to the low lateral force stability with the aim of a very gentle lateral force load of the carbon fibers in the surface formation.
  • the thermal insulation, as well as the electrical insulation can be determined by the length of the spacer threads and thus the trapped Adjust the air and the textile-technical construction of the top and bottom layers particularly well. Advantageous values can be found in the subclaims. Also, the compressive stiffness can be adjusted by the flexural rigidity, angular position and in particular length of the spacer threads, it being clear that larger lengths are less pressure-stable than smaller lengths.
  • the spacer textiles according to the invention can be coated on one side or on both sides. This makes it possible to produce a surface-closed volume of air or liquid that can be tempered via the carbon filaments.
  • the entire structure can be formed from fully flexible to stiff by the type of coating.
  • FIGS. 1 to 3 a knitted or knitted fabric according to the invention, which has been produced on a circular knitting or knitting machine, not shown, is generally designated 10.
  • the latter is designed as a so-called spacer fabric or knitted fabric which has a top and bottom or layers 16 and 18, respectively. These two sides or layers are spaced parallel to each other, wherein the distance forming the clipboard 22 is indicated by the double arrow 20, is formed by the monofilament spacer threads 14 and can be selected in the range of a few tenths of millimeters up to 1 dm. This is the only way to produce the desired versatility of the final products, which are specified in claim 13.
  • the actual consisting of synthetic threads or in mixture with natural fibers as a carrier material knit fabric is not shown for clarity, in which the carbon threads 12 are knitted with the metal conductors.
  • the electrically conductive, relatively high-resistance, flexible resistance material made of carbon threads 12 forms the actual heating conductor, while the metal conductors for the electrical leads, not shown, consist of a low-resistance material, namely a silver-plated so-called standing thread forming contact conductor, e.g. in the form of a high-stretch knit braided hose.
  • the carbon threads or filaments 12 can be arranged differently in the current-conducting knitted fabric 10 according to the invention, namely in the lower layer 18, as shown in FIG. 1, or in the upper layer 16, as shown in FIG. 2. A combination of these two embodiments is also possible.
  • an embodiment is shown in Fig. 3, in which the heating carbon filaments 12 extend not only through the upper and lower layers 16 and 18, but are additionally incorporated into the spacer cavity / intermediate layer 22.
  • the carbon threads 12, despite low lateral force stability have no breaks or broken points, which is ensured in the production process of the knitted fabric 10 according to the invention by adaptation of corresponding mechanical factors.
  • the Not shown deflection members have rounded smooth edges and large deflection radii for the carbon threads 12 with minimal friction. It is also advantageously thought to twist the carbon threads 12 to give them increased stability, especially in bends or deformations for higher-stressed textiles.
  • Twisted carbon threads 12 are also much easier to machine stitches, making the knitting process or process is safer.
  • the twisted carbon threads 12 reduce the electrostatic charge in seat covers in the automobile in addition to the heating function.
  • the spacer structure 10 solves all the problems of the prior art and enables the production of a large number of new products.
