  • heat or heating bandages or textiles are known, e.g. from the sports sector, e.g. from Lenz Products, Schwarzach, Germany, with heat conductors being applied to a type of bandage, e.g. in the form of a kidney belt.
  • the conductive threads which at least partially serve to generate heat, are introduced into the base material during its production process.
  • a heating bandage can be provided that can be produced in almost any dimensions, both in terms of length and width.
  • the bandage is easier to manufacture because the bandages are used for heating or heat generation
  • Threads are immediately introduced into the woven or knitted fabric and no additional further steps, such as the following Pulling in or applying and eg gluing or otherwise fixing heating filaments or heating wires is necessary. This also eliminates the risk of failures that can result from loosening the attachment points between the woven or knitted fabric and conductive threads, etc.
  • Base material made of knitwear is to be understood and includes both warp-knitted and knitted base materials. It is particularly preferred if the heating bandage has a length that is dimensioned such that the heating bandage can be placed once around the body area to be heated. Alternatively, however, it is also conceivable to provide a heating bandage that can be placed or wrapped several times around a body region to be heated and fixed there.
  • the width of the heating bandage is preferably 4-30 cm, in particular 4-20 cm and preferably 5-10 cm. A width of 5 cm or 10 cm is particularly preferred.

For this purpose it can be provided that insulated electrically conductive yarns are used or subsequently insulation is applied to the base material of the heating bandage, for example by a
  • the base material of the heating bandage can also be bordered by additional textile layers, e.g. a conventional bandage.
  • the conductive threads serve to generate heat and these are drawn in as weft and/or warp threads.
  • the electrically conductive threads in the case of knitted fabrics, in particular crocheted or knitted fabrics, provision can be made for the electrically conductive threads to be introduced into the knitted fabric as an additional weft thread during its manufacture.
  • the conductive threads only form part of the warp or weft threads.
  • a conductive thread is inserted as a weft, with a spacing being created between each weft insertion of conductive thread and the wefts made of non-conductive threads in between.
  • this additional weft insertion may be guided by hand, but mechanical guidance is preferred.

If the conductive weft thread extends only partially across the width of the base material, it or these threads can preferably be arranged in the middle area of the base material. However, an arrangement in the edge area, ie in the direction of the selvedges running in the longitudinal direction, is also possible. In principle, several conductive weft threads can also be drawn in.

Furthermore, it is particularly preferred to introduce elastic threads and in particular elastic conductive threads into the woven or knitted fabric.

The elasticity can be achieved via elastomeric threads, which can be wrapped with a conductive material in order to provide conductivity, in particular windings made of polyester or enameled copper wire can be provided, the core of which consists in particular of elastane.
  • cotton-elastic threads can also be used, which have been appropriately treated to produce elasticity.
  • the extensibility of The heating bandage is preferably in the range of up to 200%, in particular up to 100% and particularly preferably between 10-20%, provided an elastic design is selected.
  • the stretchability is measured according to DIN EN ISO 13934-1:2013
  • Cotton is particularly preferred as threads for the non-conductive threads, since cotton has good skin compatibility, provided the desired elastic properties of the bandage permit this.
  • Synthetic yarns e.g. from
  • Polyamide or polyester with a silver coating threads made of polyester and enameled copper wire and elastic covered yarns made of elastane with windings made of polyester and enameled copper wire.
  • combinations of the conductive and non-conductive threads mentioned are also possible.
  • conductive threads can be used, in which a textile thread, e.g. a polyester or polyamide thread, has been twisted with a wire.
  • the threads can be insulated or non-insulated yarns, with insulated yarns allowing the bandage to be wrapped several times, even overlapping one another.
  • the threads can also be selected based on their resistance. It can be provided that in the area of heat emission
  • thread is to be understood here synonymously with yarn.
  • thread can also be understood to mean groups of threads or bundles of threads, i.e. threads combined into several, which have the same course as warp or weft threads. These can be designed as twisted yarns or as a sheet of threads running essentially parallel.
  • the heating bandages are preferably designed as narrow textiles.
  • Such narrow textiles can be produced in the form of fabrics, for example, on a shuttle loom or a needle ribbon loom. If production takes place in series, the weft thread, in particular a separate weft thread, can no longer be fed in as a conductive thread manually, but via a weft color control.
  • a jacquard machine can be used as a device. In the case of small series or individual pieces, manual feeding of a conductive weft thread is also conceivable.
  • a gallon crochet machine for example, can be used to produce a narrow textile as a knitted fabric.

  • weft threads for electrical contacting or for providing heat can also be provided, which do not extend over the entire width of the base material.
  • the thread or threads for providing the heat output can also only extend over a central area between the two longitudinal side edges or lateral areas of the bandage. This can be the case in particular with a knitted fabric that is produced on a galloon crochet machine.
  • Conductive threads with a resistance of 3-100 W/m can be used as a suitable resistor, for example for the electrical supply lines or woven electrodes.
  • the resistance can be up to 500 W/m. If yarns with different resistances are used, it can be advantageous to use high-impedance yarns for generating and conducting heat and low-impedance yarns for conducting electricity. The difference in resistance is more important than the actual resistance. This is to ensure that in the areas with lower resistance no heat generation takes place, but only a transmission of the current in order to achieve a heating effect only in the areas with higher resistance.

  • a partial weft insertion is now provided, which does not lead over the entire width, ie from the left to the right edge of the knitted fabric, but instead is only entered in the middle field.
  • the conductive thread 72 runs in the middle third, which makes up about 20 of 60 rows 74 of stitches. In principle, however, entries over the entire width or a smaller width are also possible. In the present case, it runs lengthwise along about 10 stitches before it is inserted again.
  • the thread 72 is enclosed by the connection of the stitches of a wale and integrated in this way into the knitted fabric.
  • FIG. 5 now describes an elastic version of the design from FIG. Active feeding of the warp threads is advantageous when processing elastic yarns.
  • a conductive elastic wrapped yarn is used here as well as a conductive warp yarn 82.
  • the conductive weft yarn 84 in the area of the woven electrodes 16a and 16b is non-elastic.
  • a low-impedance yarn is inserted as weft 84 at the beginning and at the end in order to create woven electrodes 16a,b.
  • a high-impedance yarn 82 is part of the warp and runs longitudinally through the bandage 10.
  • Other non-conductive warp threads are identified by the reference numeral 81.
  • the electronics which are not shown here, are in turn located on a printed circuit board, which is arranged in a housing as in FIG.
  • a feedback loop as described in relation to FIG. 1, enables temperature regulation that is programmed into the program of the microcontroller.
  • the heating bandage 10 can be supplied with power via a power bank, for example.
  • crimp connectors being riveted to the bandage 10, at the other end of which a connecting cable is plugged.
  • a heating bandage 10 is created that offers advantages in production because additional work steps for applying or inserting the conductive threads can be omitted and at the same time enables mobile use.
