Definitions

  • the knit of the vertical conductive zone (Fig.1/1- zone B) is constructed so that the conductive yarn is knitted and the base yarn, excluded during the knitting process, is cut (Fig. 2/2 - zone B).
  • Fig. 1/1 zone-C The knst of the zone where the heating takes place (Fig. 1/1 zone-C) is characterised by alternated conductive yarns, while in other zones of conduction the conductive yarn is present in every rank (Fig. 2/2 - zone C).
  • the garments, as per the invention, are fitted with an electrical circuit with conductive yarn for thermal induction supplied by batteries which enable part of the body to be warmed.
  • the fabric of these garments is very thin, very light, close-fitting (with omnidirectional elasticity) almost like a second skin, and pleasing to the touch.
  • the invention consists of the production of garments, as described above, which use an integrated electrical circuit (Fig. 1/1) with a special knit of conductive yarn which are always used together with a base of different yarns; to explain better: the fabric is made with conductive yams which form an electrical circuit in the structure of the garment capable of heating parts of the body.
  • the electricity supply can be provided from the mains circuit using a plug or from batteries; the latter can be recharged using a suitable battery charger or photovoltaic panels.
  • the heat produced can be adjusted as necessary; an electronic circuit will enable different parts of the body to be heated, and can be selected by using a radio-control device.
  • the working current is significantly lower than that which can be felt by the wearer and therefore constitutes no danger for the user.
  • the invention is unique because of the use of an original knit of conductive yarns which are always used together with different, non-conductive base yarn.
  • the electrical circuit is an integral part of the knitted fabric and is made up of different structures for held or excluded stitches with no cutting or stitching, in direct connection, without interruption of any type:
  • Zone A 1 ribbed, horizontal (Fig. 1/1 -A): the knit of the base yarn is alternated in a vertical direction with the conductive yarn (Fig.2/2 - zone A).
  • Zone B which is totally covered by conductive yarn, vertical (Fig.1/1 -B): the conductive yarn is knitted and the base yarn, excluded in the knit, is cut (Fig. 2/2 - zone B).
  • Zone C with alternated conductive yarns (Fig. 1/1-C): this is the zone where the resistance is greatest and is therefore where the heating takes place (conversion of electrical energy into dissipated heat energy).
  • the conductive yarn is only knitted into alternate ranks, for example 1 rank in every 4, while in the other zones the conductive yarn is present in every rank (Fig. 2/2 - zone C).
  • the heating textile fabric works on the base of Joule's effect. That circuit consists of many conductor yarns matched with other non-conductor yarns. The conductor yarns are properly connected in series or parallel, depending on the equivalent section where the current flows, those yarns have function of conductors or resistors. On the base of Joule's principle, an electric current flowing into a conductor material produces thermal energy and the relation between those values depends on the material resistance. The resistance of material depends on a physical characteristic of the material (resistivity).
  • the conductor threads are manufactured by plating a superficial silver layer on a basic polyamide tread.
  • Silver is a metal that has the property to be one of best conductors of heat and electricity. It possible to create some heating zones by arranging a certain number of conductor threads and by connecting them in parallel by means of a proper short circuit at their ends. Each of those threads is similar to a resistor. The number of resistors working in parallel may change depending on the required temperature and the heating surface, tn order to carry the current to the proper heating zones without wasting energy, a low-resistance connection it's required.
  • the section of this conductor layer depends of the current flowing in it.
  • the supply terminals are by means of two metallic clip-buttons fixed on the textile. Those clip-buttons can be plugged to the terminals of an external device which supply the circuit.
  • the supply source consists of one or more batteries, properly connected, which capacity is chosen in function of the required heating time.
  • An electronic circuit allows the control of energy flowing into the different heating zones (fig.3/3-1).
  • This device consists of a microprocessor-based electronic circuit that manages power components like MosFets or Transistors (fig. 3/3-3).
  • the current value is modified by an electronic switch (fig.3/3-4) which could be the same component used for switching the external circuit (fig. 3/3-2). in the block diagram the functions of selection and control are divided but practically those functions could be done by the same electronic component.
  • the value of electric energy supplied to resistors (fig. 3/3-1) could be changed by modifying the conduction-time of the switching device (PWM principle).
  • the timing is managed by the microprocessor (fig. 3/3-3).
  • the switching command could be by means of a push-button (fig.3/3-5) or by means of a remote control (fig. 3/3-7). If the command is given by the push-button, the operation (increase/decrease temperature - switch heating zone) is selected by a proper command sequence depending, for instance, from the pushing time.
  • the electronic controller of the supply source checks also the status of rechargeable batteries (fig. 3/3-8) and manages their charging process.
  • the charge level of batteries is showed by a visual code, like, for instance, the blinking frequency of a
  • the recharge of batteries could be done by using two different sources: an external supply plugged to mains (fig. 3/3-11) that, by means of a proper galvanic isolation, assures the recharge of battery and the safety of operator; a photovoltaic panel (fig. 3/3-12) that assures the recharge of batteries when mains is not available.

Abstract

L'invention concerne des vêtements résistifs représentant un tricot spécial, obtenu à l'aide de machines à tricoter circulaires pourvues dans certaines zones d'un circuit électrique obtenu par tricotage direct de fil conducteur en combinaison avec une base de fil non résistif. Le circuit électrique de ce vêtement résistif est constitué par trois structures de tricotage différentes pour des 'mailles flottées ou exclues' sans coupures ni maillage, en connexion directe, sans interruption d'aucune sorte. Un circuit électronique permet le contrôle de l'énergie s'écoulant dans les différentes zones de chauffage du circuit électrique.
