Description
DESCRIPCIÓNDESCRIPTION
Tejido conductor con elevada versatilidad de utilizaciónConductive fabric with high versatility of use
La presente invención se refiere a un tejido conductor con elevada versatilidad de utilización. Más particularmente, la invención se refiere a un tejido conductor capaz de transportar alimentación eléctrica en su interior. Se conoce un tejido conductor del tipo mencionado por ejemplo a partir del documento EP 1722614 A1.The present invention refers to a conductive fabric with high versatility of use. More particularly, the invention relates to a conductive fabric capable of carrying electrical power within it. A conductive fabric of the type mentioned is known, for example, from the document EP 1722614 A1.
Como es sabido, está ampliamente extendido el uso comercial de géneros conductores, conocidos también como géneros “condutérmicos”, que se obtienen por medio de hilo continuo de cobre (el cual actúa como hilo de trama) y fibra de vidrio (que actúa como urdimbre), con el fin de proporcionar resistores eléctricos equipotenciales de múltiples sectores, que se conectan mutuamente en paralelo usando una banda de cobre plana acoplada al tejido laminado. No obstante, esta solución con una banda plana de cobre presenta algunas desventajas, que se deben en primer lugar al hecho de que la banda de cobre aplicada es extremadamente rígida, lo cual acarrea un problema para aplicaciones particulares en las que el tejido fundamentalmente debe ser flexible.As is well known, the commercial use of conductive fabrics, also known as "conduthermic" fabrics, which are obtained by means of continuous copper wire (which acts as weft thread) and fiberglass (which acts as warp) is widely extended. ), in order to provide electrical equipotential resistors of multiple sectors, which are mutually connected in parallel using a flat copper strip coupled to the laminated fabric. However, this solution with a flat copper band presents some disadvantages, which are due first of all to the fact that the applied copper band is extremely rigid, which entails a problem for particular applications in which the fabric must fundamentally be flexible.
Además, la banda de cobre aplicada puede crear problemas en caso de que sea necesario llevar a cabo un acoplamiento o unión adhesiva con resinas o materiales que deben penetrar en el tejido uniformemente, ya que la banda crearía una barrera a esta penetración.In addition, the applied copper band can create problems in the event that it is necessary to carry out a coupling or adhesive bonding with resins or materials that must penetrate the tissue uniformly, since the band would create a barrier to this penetration.
Además, otro de los inconvenientes se debe a las dilataciones lineales que puede experimentar cada material si el mismo se calienta y que, en el caso de dos materiales diferentes (tejido y banda conductora firme), en caso de encapsulación, podrían provocar roturas o separaciones.In addition, another of the drawbacks is due to the linear expansions that each material can experience if it is heated and that, in the case of two different materials (fabric and firm conductive band), in case of encapsulation, could cause breaks or separations. .
La finalidad de la presente invención es proporcionar un tejido conductor con una alta versatilidad de utilización que permita proporcionar, en un mismo tejido, zonas que tengan características específicas que sean idénticas o diferentes en función de la cantidad de material conductor que esté presente en cada área y cuyo propósito es generar calor.The purpose of the present invention is to provide a conductive fabric with a high versatility of use that makes it possible to provide, in the same fabric, areas that have specific characteristics that are identical or different depending on the amount of conductive material that is present in each area. and whose purpose is to generate heat.
Dentro de esta finalidad, uno de los objetivos de la presente invención es proporcionar un tejido conductor con una alta versatilidad de utilización y que pueda ser flexible.Within this purpose, one of the objectives of the present invention is to provide a conductive fabric with high versatility of use and that can be flexible.
Otro objetivo de la presente invención es proporcionar un tejido conductor que permita transportar tanto energía como señales eléctricas.Another objective of the present invention is to provide a conductive fabric that allows the transport of both energy and electrical signals.
Un objetivo adicional de la presente invención es proporcionar un tejido conductor que se pueda proporcionar directamente con un telar del tipo perpendicular o circular.A further object of the present invention is to provide a conductive fabric that can be directly woven with a loom of the perpendicular or circular type.
Otro objetivo de la presente invención es proporcionar un tejido conductor que se pueda proporcionar en función de la potencia que se va a transportar.Another objective of the present invention is to provide a conductive fabric that can be provided depending on the power to be carried.
Otro objetivo de la presente invención es proporcionar un tejido conductor que sea altamente fiable, relativamente sencillo de obtener y con costes competitivos.Another object of the present invention is to provide a conductive fabric that is highly reliable, relatively easy to obtain, and cost competitive.
Esta finalidad, así como estos y otros objetivos que se pondrán más claramente de manifiesto en lo sucesivo en la presente, se alcanzan por medio de un tejido conductor según la reivindicación 1.This purpose, as well as these and other objectives that will become clearer hereinafter, are achieved by means of a conductive fabric according to claim 1.
Otras características y ventajas de la invención se pondrán más claramente de manifiesto a partir de la descripción de formas de realización preferidas, aunque no limitativas, del tejido conductor según la invención, ilustrado a título de ejemplo no limitativo en los dibujos adjuntos, en los que:Other features and advantages of the invention will become clearer from the description of preferred, though non-limiting, embodiments of the conductive fabric according to the invention, illustrated by way of non-limiting example in the attached drawings, in which :
la figura 1 es una vista de una primera forma de realización del tejido según la presente invención;Figure 1 is a view of a first embodiment of the fabric according to the present invention;
la figura 2 es una vista de un tejido fuera del alcance de las reivindicaciones independientes;Figure 2 is a view of a fabric outside the scope of the independent claims;
la figura 3 es una vista de una segunda forma de realización del tejido según la presente invención.Figure 3 is a view of a second embodiment of the fabric according to the present invention.
En referencia a las figuras, en las que los números de referencia iguales se corresponden con elementos idénticos, el tejido conductor según la invención, designado en general con el número de referencia 1, comprende una pluralidad de hilos de urdimbre 2, comprendiendo los hilos de urdimbre por lo menos dos hilos de urdimbre 3 conductores y aislados que están adaptados para transportar alimentación eléctrica dentro del propio tejido 1, como si fueran un cable de línea que transporta alimentación y/o señales.Referring to the figures, in which the same reference numerals correspond to identical elements, the conductive fabric according to the invention, generally designated with the reference numeral 1, comprises a plurality of warp threads 2, the warp threads comprising warp at least two insulated 3-conductor warp threads that are adapted to carry electrical power within the fabric 1 itself, as if they were a line cable that carries power and/or signals.
En este caso, el hilo de trama 4 es un hilo continuo conductor y aislado, por ejemplo, realizado con cobre, que interseca los hilos de suministro de alimentación 3, extrayendo alimentación de ellos. In this case, the weft wire 4 is a continuous conductive and insulated wire, for example made of copper, which intersects the power supply wires 3, drawing power from them.
Más particularmente, el hilo de trama 4 es un hilo de cobre que va de un lado a otro, entrelazándose con los hilos de urdimbre que están realizados convenientemente, por ejemplo, con fibra de vidrio. El hilo continuo permite proporcionar un tejido resistivo con emisiones electromagnéticas prácticamente nulas. Esto es debido al hecho de que el hilo continuo que al tejerse entra, en cada retorno discurre prácticamente en contacto con la pasada directa; a continuación, el telar llevar a cabo el batido deseado y seguidamente otra pasada directa y de retorno en contacto. Con esta arquitectura del tejido, el campo electromagnético generado por un cable eléctrico al que atraviesa una corriente que se mueve en una dirección es cancelado por el campo electromagnético opuesto generado por el cable sucesivo (en contacto) al que atraviesa la misma corriente, pero en el sentido opuesto. El hilo de trama 4 “se conecta” al hilo de urdimbre conductor 3 por medio de unas soldaduras 5 que se pueden proporcionar mediante soldadura por puntos, soldadura con estaño, pasta para soldar, ultrasonidos o cualquier otro procedimiento conocido para proporcionar sectores eléctricos que son alimentados por los hilos de urdimbre conductores 3. More particularly, the weft thread 4 is a copper thread that runs from one side to the other, intertwining with the warp threads that are conveniently made, for example, of fiberglass. The continuous thread makes it possible to provide a resistive fabric with practically zero electromagnetic emissions. This is due to the fact that the continuous thread that enters when woven, in each return runs practically in contact with the direct course; then the loom performs the desired beating followed by another direct and return pass in contact. With this architecture of the fabric, the electromagnetic field generated by an electric cable that is crossed by a current moving in one direction is canceled by the opposite electromagnetic field generated by the successive cable (in contact) that is crossed by the same current, but in the opposite sense. The weft thread 4 is "connected" to the conductive warp thread 3 by means of welds 5 which can be provided by spot welding, soldering, soldering paste, ultrasonics or any other known procedure for providing electrical sectors that are powered by the conductive warp threads 3.
Convenientemente, para evitar la deformación del tejido durante cualquier proceso de colaminación y calandrado, es posible prever la inserción en la trama, la urdimbre, o en ambas direcciones, durante el tejido, de un microfilamento 8 realizado con vidrio, el cual se suelda en caliente sobre el hilo conductor aislado, o sobre el hilo 2 realizado con material aislante, generando una malla que posibilita el aumento de la resistencia al estiramiento del tejido en las diversas direcciones, incluida la oblicua.Conveniently, in order to avoid deformation of the fabric during any collaging and calendering process, it is possible to provide for the insertion in the weft, the warp, or in both directions, during weaving, of a microfilament 8 made of glass, which is welded in heat on the insulated conductive wire, or on the wire 2 made of insulating material, generating a mesh that makes it possible to increase the resistance to stretching of the fabric in various directions, including the oblique one.
El tejido descrito anteriormente, se proporciona mediante tejido continuo sobre un telar, y también es posible decidir las dimensiones en relación con la potencia a transportar.The fabric described above is provided by continuous weaving on a loom, and it is also possible to decide the dimensions in relation to the power to be transported.
El tejido antes descrito permite proporcionar en su interior zonas que tienen características específicas mutuamente idénticas o diferentes en función de la cantidad de material conductor que está presente en cada sector (longitud y sección transversal del hilo, resistencia específica).The fabric described above makes it possible to provide within it zones having mutually identical or different specific characteristics depending on the amount of conductive material that is present in each sector (length and cross section of the wire, specific resistance).
Por lo tanto, considerando que el tejido se usa como resistor eléctrico para producir calor, es posible obtener artículos con zonas que tienen una resistencia variable las cuales, por lo tanto, son capaces de entregar diferentes niveles de potencia y/o de alimentarse con diferentes voltajes de suministro de alimentación.Therefore, considering that the fabric is used as an electrical resistor to produce heat, it is possible to obtain articles with zones that have a variable resistance which, therefore, are capable of delivering different power levels and/or being fed with different power supply voltages.
El tejido se puede calandrar o acoplar con materiales aislantes, tales como siliconas, EPDM, resinas de otro tipo y gomas en general.The fabric can be calendered or coupled with insulating materials, such as silicones, EPDM, other types of resins and rubber in general.
Como ejemplo fuera del alcance de la presente invención, el tejido, en lugar de con una trama continua, se puede realizar con una trama realizada con hilo, por ejemplo, hilo de cobre, la cual es simple, en este caso indicada con el número de referencia 10.As an example outside the scope of the present invention, the fabric, instead of with a continuous weft, can be made with a weft made with wire, for example, copper wire, which is simple, in this case indicated with the number reference 10.
Los dos hilos de urdimbre de suministro de alimentación 3 cruzan el hilo de trama simple 10 y dicho hilo de trama 10 se suelda por la intersección del hilo de urdimbre de suministro de alimentación 3 con las soldaduras 5 y con un hilo metálico de conexión 9 que tiene el propósito de cerrar el circuito.The two power supply warp threads 3 cross the single weft thread 10 and said weft thread 10 is welded by the intersection of the power supply warp thread 3 with the welds 5 and with a connecting wire 9 which It is intended to close the circuit.
De modo similar, en una segunda forma de realización, es posible hacer uso del principio en el que se basa la presente invención incluso en un tejido de “malla” que normalmente se obtiene por medio de una tricotosa por trama circular. En este caso, figura 3, el tejido 1 comprende una pluralidad de hilos de trama que alternativamente pueden ser del tipo aislante o del tipo conductor aislado 3. Se usarán por lo menos dos de estos últimos para suministrar alimentación al circuito compuesto por el hilo conductor aislado 4 que actuará como resistor (por ejemplo, hilo de cobre) y otros hilos no conductores 2 (por ejemplo, hilo de vidrio o poliéster).Similarly, in a second embodiment, it is possible to make use of the principle on which the present invention is based even on a "mesh" fabric that is normally obtained by means of a circular weft knitting machine. In this case, figure 3, the fabric 1 comprises a plurality of weft threads that can alternatively be of the insulating type or of the insulated conductor type 3. At least two of the latter will be used to supply power to the circuit made up of the conductive thread insulated 4 that will act as a resistor (for example, copper wire) and other non-conductive wires 2 (for example, glass or polyester wire).
Ventajosamente, los hilos de urdimbre del tipo conductor se pueden proporcionar por medio de una cinta plana realizada con metal, por ejemplo, realizada con cobre, que sea muy delgada, tal como para no comprometer la flexibilidad del tejido, y que se pueda usar fácilmente en lugar de un hilo de urdimbre.Advantageously, the warp threads of the conductive type can be provided by means of a flat tape made of metal, for example made of copper, which is very thin, such as not to compromise the flexibility of the fabric, and which can be easily used. instead of a warp thread.
En la práctica, se ha observado que el tejido según la invención alcanza en su totalidad la finalidad y objetivos pretendidos, pudiendo proporcionar un tejido que puede ser suministrado con energía eléctrica, con unas zonas que tienen resistencias diferentes en función de los requisitos.In practice, it has been observed that the fabric according to the invention fully achieves the intended purpose and objectives, being able to provide a fabric that can be supplied with electrical energy, with areas that have different resistances depending on the requirements.
El tejido así concebido es susceptible de numerosas modificaciones y variaciones dentro del alcance de las reivindicaciones adjuntas.The fabric thus conceived is susceptible to numerous modifications and variations within the scope of the appended claims.
En la práctica, los materiales usados, así como las eventuales formas, pueden ser cualesquiera de acuerdo con los requisitos y el estado de la técnica.In practice, the materials used, as well as the possible shapes, can be any according to the requirements and the state of the art.
