Definitions

  • This invention refers to a heatable fabric that uses electrical energy as a heat source as a result of the Joule effect; that is the heat produced depends on the resistance of a conductive coating to the passage of an electrical current.
  • the object of the invention is to achieve a fabric coating with a heatable element for particular application in making clothing and accessories, also applicable to the household textile industry, for example in mattresses, bed linen, carpets, curtains, decorative coverings for floors and walls, etc., being also applicable for heating floors, walls and ceilings, car interiors, etc.
  • a further object of the invention is to achieve a fabric that is heatable by electrical energy and which offers a high level of user safety.
  • the invention therefore lies in the field of the textile industry.
  • this type of device incorporates a circuit comprising a resistance that is suitably distributed over an inner core so that the resistance is adequately insulated electrically, and then covered by textile on both sides of the circuit.
  • these blankets have a very considerable thickness, reduced flexibility and other problems that make them impossible to be used, for example, to make an article of clothing such as a sweater, the inner lining of shoes, etc.
  • the heatable fabric proposed by the invention completely resolves the abovementioned problem and the aspects mentioned.
  • the electrical circuit constituting the heat source is comprised of a coating on the fabric in question.
  • the idea is for the textile article, of any size or shape, to incorporate a couple of electrodes whose function is to transport electricity without loss, while the fabric is coated with a semiconductor resin that connects the said electrodes; this resin being the means to generate heat.
  • the result is a circuit of resistances in series and parallel that generates the heat required for the different applications.
  • the conducting electrodes may be comprised of strips made of copper, silver, etc., whereas the semiconducting resin is formulated with a percentage of graphite, carbon, steel, etc. powder.
  • a perfect union between the conducting strips and the fabric coating of semiconducting resin is assured by sewing the conducting strip to the fabric coated with the semiconducting resin using a special thread and then applying a laminate using temperature and pressure on an thermal adhesive tape placed over the conducting strip, thus preventing any electrical loss due to false contacts.
  • the circuit integrated in the heatable fabric may be connected to a 230-240 volt power supply, etc, with suitable safety insulation.
  • a very low voltage source may also be used, for example 12 volts, thus avoiding, on the one hand, the problem of possible electric shock that could injure the user, providing adequate safety insulation and furthermore this very low voltage, in conjunction with the use of direct current, enables providing power to the fabric using a battery, thus giving the user complete independence when the fabric forms part of an article of clothing or similar.
  • a heatable fabric manufactured in accordance with the object of this invention is a conventional fabric (1) coated with a semiconducting resin on its whole width and length (2), which is inserted into the structure of the fabric, thus conserving its flexibility.
  • the conducting strips (4, 4') form the electrodes located at the edges and will be used for connection to the power supply, not shown.
  • the semiconductor coating (2) specifically with some of them in the case of figure 1 , they incorporate a certain percentage of particles of graphite, carbon, steel, etc.
  • connection between the semiconductor coating (2) and the electrodes (4, 4') is made by means of contact as shown in figure 2 .
  • the plastic insulation (6, 6') is placed on both sides, covering the assembly comprised of the fabric coated with the semiconductor layer together with the two electrodes (5), to ensure they are electrically insulated.
  • this plastic insulation may be comprised of a coating of synthetic resins depending on the voltage, for more or less insulating power, for example for 12 volts the same plastic insulation would not be used as for 230 volts; 12 volt insulation would be possible with the synthetic coating.
