Abstract

The textile material, woven from polymer-coated threads, has some of its warp or weft threads made from brass-covered steel, also polymer coated and with a different color to the basic threads. The wire threads are able to slide relative to the main threads so they can be extracted from the material, and certain of the crossing wires can be welded together or to those in other layers of material.

Description

Domaine techniqueTechnical area

L'invention se rattache au domaine des textiles techniques, et plus précisément aux textiles conducteurs de l'électricité et/ou de renforcement. Elle trouve des applications multiples, et notamment dans la réalisation de bâches de camion, d'éléments de toiture souple, ou encore d'ameublement ou d'aménagement intérieur. Elle concerne plus particulièrement un tissu incorporant des fils métalliques particuliers qui permettent une configuration très aisée du circuit électrique dont ils font partie.The invention relates to the field of technical textiles, and more specifically to electrically conductive and / or reinforcing textiles. It finds multiple applications, and in particular in the realization of truck tarpaulins, flexible roofing elements, or furniture or interior design. It relates more particularly to a fabric incorporating special metallic wires which allow very easy configuration of the electrical circuit of which they are part.

Techniques antérieuresPrevious techniques

De façon générale, les textiles conducteurs comprennent des fils de chaíne et de trame qui sont conducteurs de l'électricité. Ces différents fils de chaíne et de trame sont reliés entre eux par des liaisons électriques, de manière à définir un circuit électrique qui est ensuite connecté à une source d'énergie électrique. La circulation d'un courant à l'intérieur de différents fils de chaíne et de trame permet par effet Joule de libérer une certaine quantité de chaleur.In general, conductive textiles include yarns warp and weft which are conductors of electricity. These different sons chain and weft are connected together by electrical connections, way to define an electrical circuit which is then connected to a source of electrical energy. The flow of a current inside different warp and weft yarn allows by Joule effect to release a certain amount of heat.

Le Demandeur a déposé une demande de brevet français sous le numéro FR 01.02737, non publiée à la date de la présente demande, qui décrit un type particulier de ces tissus conducteurs. Plus précisément, ce tissu comprend par exemple dans un sens chaíne des fils métalliques et dans le sens trame, des fils à base de fibres de carbone. Les fils métalliques présentant des zones de contact avec les fils de carbone qui leurs sont perpendiculaires, ils définissent des zones équipotentielles via lesquelles une tension électrique peut être appliquée sur les fils de carbone. Ce type de tissu présente certains avantages, mais il présente un inconvénient en ce qui concerne la qualité des contacts électriques entre les différents fils conducteurs.The Applicant filed a French patent application under the number FR 01.02737, not published on the date of this request, which describes a particular type of these conductive fabrics. Specifically, this fabric includes for example in a chain direction of the metallic threads and in the weft direction, carbon fiber yarns. Metallic wires having areas of contact with their carbon threads perpendicular, they define equipotential zones via which an electrical voltage can be applied to the carbon wires. This kind of fabric has certain advantages, but it has a disadvantage in that concerns the quality of the electrical contacts between the different wires conductors.

En effet, la qualité du contact électrique entre les fils se croisant est essentiellement fonction de paramètres dimensionnels des fils, et des méthodes de tissage. On conçoit donc qu'en fonction de la variation de chacun des ces paramètres, la qualité du contact évolue, avec pour conséquence l'apparition de zones résistives très localisées, dégradant l'homogénéité du chauffage.Indeed, the quality of the electrical contact between the crossing wires is essentially a function of dimensional parameters of the wires, and weaving methods. We can therefore see that as a function of the variation of each of these parameters, the quality of the contact changes, with for consequence the appearance of very localized resistive zones, degrading homogeneity of heating.

Le Demandeur a également déposé une autre demande de brevet français sous le numéro FR 01.02908, non publiée à la date de la présente demande. Cette demande de brevet est relative à un tissu réalisé à partir de fils préalablement gainés d'une couche de matériau polymère, et typiquement du polychlorure de vinyle. Ces différents fils constituent des renforts du tissu, et confèrent à ce dernier des propriétés anti-lacération. Certains de ces fils sont également conducteurs de l'électricité, et sont utilisés pour former un circuit électrique dont la coupure est le signe qu'une lacération est intervenue. Cette coupure peut être signalée par un dispositif approprié relié à ce circuit. La réalisation de ce circuit électrique s'obtient par la jonction de différents fils métalliques parallèles, au niveau des lisières du tissu.The Applicant has also filed another patent application French under the number FR 01.02908, not published on the date hereof request. This patent application relates to a fabric made from yarns previously sheathed with a layer of polymeric material, and typically polyvinyl chloride. These different threads constitute fabric reinforcements, and give it anti-laceration properties. Some of these wires are also conductors of electricity, and are used to form an electrical circuit whose breaking is the sign that a laceration occurred. This cut can be signaled by a device appropriate connected to this circuit. The realization of this electrical circuit is obtained by the junction of different parallel metallic wires, at the level of selvedges of the fabric.

Un objectif de l'invention est de fournir un tissu qui intègre des fils métalliques conducteurs pour réaliser des circuits électriques. Un autre objectif est de permettre la configuration très aisée de ce genre de circuit, par des opérations simples, qui puissent être réalisées sans dégrader les autres propriétés du tissu, et notamment l'intégrité des autres fils gainés de matériau polymère.An object of the invention is to provide a fabric which incorporates threads metallic conductors for making electrical circuits. Another objective is to allow very easy configuration of this kind of circuit, by simple operations, which can be carried out without degrading the other properties of the fabric, and in particular the integrity of the other threads covered with polymer material.

Un autre objectif est de permettre la réalisation de ces opérations sur toute forme de tissu, quelles qu'en soient les découpes.Another objective is to allow these operations to be carried out on any form of fabric, whatever the cuts.

Exposé de l'inventionStatement of the invention

L'invention concerne donc un tissu réalisé à partir de fils gainés d'un matériau polymère.The invention therefore relates to a fabric made from threads sheathed with a polymer material.

Conformément à l'invention, certains des fils de chaíne et/ou de trame de ce tissu sont réalisés à partir de fils d'acier laitonnés.According to the invention, some of the warp and / or weft threads of this fabric are made from brass plated steel wires.

Ainsi, pour réaliser les différentes liaisons électriques permettant de relier les fils de chaíne et de trame, il suffit de souder les fils métalliques, aux endroits nécessaires. Le monteur, ou le confectionneur de la pièce de tissu aux formes définitives, peut donc réaliser ces opérations sans difficulté. Il lui suffit alors de réaliser des points de soudure au niveau des croisements des fils devant être reliés électriquement. Cette soudure est possible avec l'emploi d'appareils de soudure qui travaillent à basse température, et dont la source de chaleur ne dégrade pas le matériau polymère des fils avoisinants. On a en effet constaté que les fils d'acier laitonnés présentaient une bonne capacité à être soudés à l'étain, à des températures de l'ordre de 120°C. Cette bonne capacité d'être soudé est également mise à profit pour le raccordement des fils métalliques avec les organes de connexion vis-à-vis du circuit d'alimentation électrique.Thus, to make the various electrical connections allowing connect the warp and weft threads, just weld the metallic threads, where necessary. The fitter, or the maker of the piece fabric with definitive shapes, can therefore perform these operations without difficulty. It then suffices for it to make welding points at the crossing of the wires to be electrically connected. This weld is possible with the use of welding devices that work at low temperature, and the heat source of which does not degrade the material polymer of neighboring yarns. It has indeed been observed that the steel wires with a good capacity to be soldered to tin, to temperatures of the order of 120 ° C. This good ability to be welded is also used for the connection of metallic wires with connection members vis-à-vis the electrical supply circuit.

Ces fils métalliques d'acier laitonnés sont généralement utilisés à l'intérieur des structures de carcasses de pneumatiques. La couche extérieure de laiton est utilisée pour les opérations de tréfilage, car elle évite l'emploi de lubrifiants qui s'avèreraient gênants pour l'adhésion recherchée avec le caoutchouc des pneumatiques. Il se trouve également que le caoutchouc des pneumatiques possède une capacité d'adhésion sur ce métal.These brass plated steel wires are generally used for inside tire carcass structures. Layer brass exterior is used for wire drawing operations because it avoids the use of lubricants which would prove troublesome for the desired adhesion with the rubber of the tires. It also happens that the rubber tires has an adhesion capacity on this metal.

C'est pour un tout autre effet que les fils métalliques d'acier laitonnés sont utilisés dans la présente invention, et plus précisément pour leur capacité à pouvoir être soudés à l'étain, et donc à faible température. En outre, la bonne résistance à la traction de l'acier confère des propriétés anti-lacération à un tel tissu.It is for a completely different effect than brass plated steel wires are used in the present invention, and more specifically for their ability to be soldered with tin, and therefore at low temperature. In in addition, the good tensile strength of steel gives anti-laceration properties to such a fabric.

Les fils d'acier laitonnés utilisés dans le tissu conforme à l'invention peuvent être soit nus, soit être également gainés d'un matériau polymère. Dans le premier cas, le tissu sera alors incorporé dans un matériau plus complexe pour éviter les risques de chocs électriques. Lorsque les fils d'acier laitonnés sont également gainés, les différents fils du tissu présentent un aspect sensiblement identique. Les soudures sont alors réalisées au niveau des croisements des fils à relier. L'emploi de l'appareillage à souder approprié permet d'éliminer la couche de matériau polymère uniquement où la soudure est nécessaire, sans provoquer de dégradation de ce matériau polymère aux alentours. Ainsi, seuls les points de soudure sont apparents sur les faces du tissu.Brass-plated steel wires used in the fabric according to the invention can be either bare or also be sheathed with a polymer material. In the first case, the fabric will then be incorporated into a more complex to avoid the risk of electric shock. When the sons of brass plated steel are also sheathed, the different threads of the fabric have a substantially identical appearance. The welds are then made at the crossings of the wires to be connected. The use of the appropriate welding equipment eliminates the layer of material polymer only where soldering is required, without causing degradation of this surrounding polymer material. So only the points solder are visible on the sides of the fabric.

Dans le cas où les fils métalliques sont gainés, ils seront avantageusement d'une couleur différente des autres fils avoisinants de manière à pouvoir être repérés lors des opérations de soudure. Le matériau polymère formant sa gaine peut être soit d'une couleur spécifique, différente de toutes celles des autres fils. On peut également disposer ces fils métalliques à des emplacements déterminés dans des motifs réalisés sur le tissu. A titre d'exemple, les fils métalliques peuvent être disposés en bordure d'une rayure formée par des gaines de couleurs différentes.In the case where the metal wires are sheathed, they will be advantageously of a different color from the other neighboring threads of so that they can be identified during welding operations. The material polymer forming its sheath can be either of a specific color, different from all of the other sons. We can also arrange these metal wires at determined locations in patterns made on the fabric. By way of example, the metal wires can be arranged in border of a stripe formed by sheaths of different colors.

En pratique, les fils de chaíne et de trame entourant les fils métalliques sont typiquement des fils à base de polyester gainés de polychlorure de vinyle. Néanmoins, d'autres fils synthétiques, et d'autres matériaux de gainage peuvent être employés, et sans sortir du cadre de l'invention.In practice, the warp and weft threads surrounding the threads metallic are typically polyester-based yarns coated with polyvinyl chloride. However, other synthetic yarns, and others cladding materials can be used, and without going outside the scope of the invention.

Avantageusement en pratique, les fils d'acier laitonnés sont aptes à coulisser à l'intérieur du tissu, de façon à être extractibles. Autrement dit, il est possible de ne conserver dans le tissu que les fils métalliques intégrés dans le circuit électrique. Les autres fils peuvent être éliminés pour éviter les contacts parasites. Dans ce cas, une traction sur les fils métalliques inutiles leur permet de glisser sur les gaines des fils perpendiculaires, et ils peuvent aussi être éliminés du tissu.Advantageously in practice, brass-plated steel wires are capable of slide inside the fabric, so as to be extractable. In other words, it it is possible to keep in the fabric only the integrated metallic threads in the electrical circuit. The other wires can be eliminated to avoid stray contacts. In this case, traction on the metal wires unnecessary allows them to slide over the sheaths of the perpendicular wires, and they can also be removed from the tissue.

En pratique, lorsque le tissu comporte des soudures de certaines de ces fils de chaíne et de trame formant un circuit, il peut être associé avec un dispositif de mesure de la continuité électrique de ce circuit. Un tel dispositif permet ainsi de détecter une coupure de ce circuit, pouvant résulter d'une lacération.In practice, when the fabric has welds of some of these warp and weft threads forming a circuit, it can be associated with a device for measuring the electrical continuity of this circuit. Such device thus makes it possible to detect a break in this circuit, which can result from a laceration.

Un tel tissu peut donc être utilisé en tant que bardage, et plus généralement en tant qu'élément d'architecture, et par exemple de cloisons qui doivent résister à des tentatives de lacération, ou plus précisément signaler de telles tentatives. Le tissu peut être utilisé en association avec d'autres textiles étanches pour la réalisation de bâches de camion ou équivalents.Such a fabric can therefore be used as siding, and more generally as an architectural element, for example of partitions who must resist laceration attempts, or more precisely report such attempts. The fabric can be used in combination with other waterproof textiles for making truck tarpaulins or equivalents.

En association avec une alimentation électrique appropriée, le tissu conforme à l'invention peut être utilisé en tant que moyen de chauffage, et intégré dans des couvertures de sièges de véhicules automobiles. Il peut être également intégré dans des housses indépendantes, qui peuvent être installées sur des sièges existants. De tels tissus peuvent également être utilisés en tant que géotextiles chauffants. Ils sont alors intégrés dans la structure de la route, de manière à dissiper une quantité d'énergie contrôlée, et éviter les dégradations des routes, notamment à cause de phénomènes de gel.In combination with an appropriate power supply, the fabric according to the invention can be used as a heating means, and integrated into motor vehicle seat covers. He can be also integrated in independent covers, which can be installed on existing seats. Such fabrics can also be used as heating geotextiles. They are then integrated into the structure of the road, so as to dissipate a controlled amount of energy, and avoid road degradation, particularly due to phenomena of gel.

En pratique, il est également possible de réaliser un complexe textile en associant deux tissus comme décrits ci-avant. Dans ce cas, les deux nappes textiles présentent des fils d'acier laitonné qui sont perpendiculaires d'une nappe à l'autre. Certains fils d'acier laitonné de la première nappe sont alors soudés à certains fils analogues de l'autre nappe. Cette connexion peut être réalisée en tout point et notamment en périphérie des nappes. Il est ainsi possible d'alimenter électriquement de façon différentiée les deux nappes textiles, tout en améliorant la résistance à la lacération du complexe du fait de sa constitution en deux couches distinctes.In practice, it is also possible to make a textile complex by combining two fabrics as described above. In this case, both textile tablecloths have brass steel wires which are perpendicular from one tablecloth to another. Some brass-plated steel wires from the first layer are then soldered to certain similar wires of the other sheet. This connection can be performed at any point and in particular at the periphery of the layers. It is thus possible to power the two differently textile tablecloths, while improving the laceration resistance of the complex because of its constitution in two distinct layers.

Manières de réaliser l'inventionWays to realize the invention

Les fils utilisés pour réaliser le tissu conforme à l'invention sont principalement de deux types, à savoir des fils synthétiques, et des fils métalliques. Les fils synthétiques peuvent avantageusement être des fils en polyester, d'un titre variant de 550 à 1100 dtex. Ces fils de polyester sont gainés d'une couche de matériau polymère, et typiquement du polychlorure de vinyl. Cette couche présente une épaisseur de l'ordre de 0,2 mm.The threads used to make the fabric according to the invention are mainly of two types, namely synthetic yarns, and yarns metal. The synthetic yarns can advantageously be yarns made of polyester, of a title varying from 550 to 1100 dtex. These polyester yarns are sheathed with a layer of polymer material, and typically polychloride vinyl. This layer has a thickness of the order of 0.2 mm.

Les fils métalliques utilisés sont des fils en acier laitonnés.The metal wires used are brass-plated steel wires.

On a obtenu de bons résultats en utilisant des fils d'acier au carbone, réalisés par le câblage de trois brins chacun. Le fil métallique ainsi obtenu présente un diamètre de 0,52 mm, pour des brins unitaires d'un diamètre voisin de 0,15 mm.Good results have been obtained using carbon steel wires, made by wiring three strands each. The metal wire thus obtained has a diameter of 0.52 mm, for individual strands with a diameter about 0.15 mm.

On a également obtenu de bons résultats en utilisant des fils métalliques comportant sept brins câblés, chaque brin possédant un diamètre de l'ordre de 0,2 mm.Good results have also been obtained using wires metal with seven strands wired, each strand having a diameter of the order of 0.2 mm.

Les aciers utilisés présentent une résistance mécanique de l'ordre de 200 à 350 kilogrammes par m2. Cette résistance peut être inférieure lorsqu'il n'est pas nécessaire que le tissu possède une résistance mécanique importante. C'est par exemple le cas lorsqu'il est uniquement souhaitable de signaler une lacération, sans alourdir trop fortement le tissu.The steels used have a mechanical strength of the order of 200 to 350 kilograms per m 2 . This resistance can be lower when it is not necessary for the fabric to have a high mechanical resistance. This is for example the case when it is only desirable to report a laceration, without weighing down the tissue too much.

Le revêtement de laiton présent sur les fils métalliques représente une épaisseur de quelques micromètres à quelques dizaines de micromètres. Ce laiton est avantageusement formulé pour sa bonne capacité à être soudé à l'étain.The brass coating on the metal wires represents a thickness from a few micrometers to a few tens of micrometers. This brass is advantageously formulated for its good ability to be welded to tin.

Les fils métalliques sont disposés à intervalles réguliers, par exemple tous les 5 cm, cette distance correspondant sensiblement aux dimensions d'une main. On permet ainsi la détection de toute lacération qui aurait pour objectif de laisser passer la main ou le bras. The metal wires are arranged at regular intervals, for example every 5 cm, this distance corresponding substantially to the dimensions with one hand. This allows the detection of any laceration that would have aim to let your hand or arm pass.

Il ressort de ce qui précède que le tissu conforme à l'invention présente de multiples avantages, et notamment celui de pouvoir être configuré à souhait en ce qui concerne le circuit électrique que forment les fils métalliques d'acier laitonnés caractéristiques qu'il inclut. L'emploi de ce matériau permet de réaliser les soudures entre les fils de chaíne et de trame à relier, en utilisant une soudure à l'étain qui expose les gaines de matériau polymère à des températures insuffisantes pour en provoquer la destruction.It appears from the above that the fabric according to the invention has multiple advantages, including being able to be configured to suit the electrical circuit formed by characteristic brass plated steel wire it includes. The use of this material allows the welds to be made between the chain wires and weft to be connected, using a tin solder which exposes the sheaths of polymeric material at temperatures insufficient to cause it to destruction.

Un tel tissu présente de multiples applications, notamment en tant que tissu chauffant et en tant que tissu anti-lacération.Such a fabric has multiple applications, in particular as heating cloth and as an anti-laceration cloth.
