Abstract
Description
Le secteur technique de la présente invention est celui des tissus et plus particulièrement des procédés de raccordement de deux lés de tissus.The technical field of the present invention is that of tissues and more particularly methods of connecting two tissue webs.
Pour raccorder deux lés de tissu on peut utiliser divers moyens comme par exemple une couture des deux bords en recouvrement, une couture bord à bord, l'application d'une bande de raccordement appliquée sur les deux lés disposés côte à côte, etc...To connect two fabric webs one can use various means such as for example a stitching of the two overlapping edges, an edge-to-edge sewing, the application of a connecting strip applied to the two strips arranged side by side, etc. .
Lorsque le tissu présente certaines propriétés le mode de raccordement devient important car il peut réduire voir annuler les propriétés intrinsèques de ce tissu. Ainsi, dans le cas d'un tissu présentant des propriétés de protection électromagnétique la continuité électrique du tissu n'est pas assurée par les liaisons classiques évoquées ci-dessus. En effet, ce genre de tissu présente la caractéristique de présenter une structure à trois dimensions et la couture provoque l'arrêt de la continuité électrique et donc la perte des propriétés de protection électromagnétique.When the fabric has certain properties the connection mode becomes important because it can reduce or cancel the intrinsic properties of this fabric. Thus, in the case of a fabric having electromagnetic protection properties, the electrical continuity of the fabric is not ensured by the conventional bonds mentioned above. Indeed, this kind of fabric has the characteristic of having a three-dimensional structure and the seam causes the stop of the electrical continuity and thus the loss of the electromagnetic protection properties.
Le brevet FR-E-95308 décrit un procédé de fabrication d'un tissu comportant plusieurs couches de fils de trame en combinaison avec des fils de chaîne afin de réaliser un tissu multicouches. Dans ce document il est notamment décrit un procédé permettant le raccordement de deux lés de tissus. Pour cela, on arrête le tissage de seize niveaux et on réduit le nombre de niveaux pour obtenir le long d'une bande une épaisseur moindre. Il n'est cependant pas explicitement décrit de mode spécifique de raccordement. De plus ce document ne prévoit pas l'utilisation de fils métalliques à tissage à trois dimensions, ni de moyen permettant d'assurer la continuité électrique.FR-E-95308 discloses a method of manufacturing a fabric having several layers of weft yarns in combination with warp yarns to produce a multilayer fabric. In this document, a method for connecting two fabric webs is described. For this, we stop the weaving of sixteen levels and reduces the number of levels to obtain along a band a lower thickness. However, it is not explicitly described specific connection mode. In addition, this document does not provide for the use of three-dimensional woven wire or means for ensuring electrical continuity.
Le brevet FR-2745690 décrit un vêtement de protection contre le rayonnement électromagnétique. Ce vêtement est réalisé au moyen d'un tissu conducteur électrique disposé entre une enveloppe intérieure et une enveloppe extérieure. Ce vêtement est réalisé de sorte à ce qu'il n'y ait pas d'interruption de conductivité électrique dans les zones de couture ou d'assemblage des différents lés. Cependant le tissu mis en oeuvre dans ce brevet n'est pas un tissu à tissage de fils métalliques selon trois dimensions et il n'est pas décrit clairement dans ce brevet de procédé de raccordement de deux lés de tissu ayant des propriétés de protection électromagnétique.FR-2745690 discloses a protective clothing against electromagnetic radiation. This garment is made by means of an electrically conductive fabric disposed between an inner envelope and an outer envelope. This garment is made so that there is no interruption of electrical conductivity in the sewing or assembly areas of the different strips. However, The fabric used in this patent is not a metal wire weave fabric in three dimensions and it is not clearly described in this method patent for connecting two fabric strips having electromagnetic protection properties.
Le brevet US-6068009 décrit un abri mobile recouvert d'un tissu ayant des propriétés de protection électromagnétique. Ce brevet décrit un procédé de raccordement de deux lés constituant l'habillage de l'abri et ayant des propriétés de protection électromagnétique. Le procédé de raccordement consiste à enrouler l'une dans l'autre les extrémités des deux lés à assembler puis de les coudre ensemble. Un tel procédé ne peut être appliquer à un tissu à tissage selon trois dimensions car il présente l'inconvénient d'engendrer une surépaisseur au niveau du raccord. De plus, il ne permet pas le raccord de deux lés dont la surface extérieure ne serait pas électriquement conductrice.US-6068009 discloses a mobile shelter covered with a fabric having electromagnetic protection properties. This patent describes a method of connecting two strips constituting the covering of the shelter and having electromagnetic protection properties. The connection method is to wind into one another the ends of the two strips to be assembled and sew them together. Such a method can not be applied to a woven fabric in three dimensions because it has the disadvantage of generating an extra thickness at the connection. In addition, it does not allow the connection of two strips whose outer surface is not electrically conductive.
Le but de la présente invention est de fournir un procédé de raccordement de deux lés de tissu assurant la continuité électrique ainsi que l'atténuation électromagnétique.The object of the present invention is to provide a method of connecting two fabric strips providing electrical continuity as well as electromagnetic attenuation.
L'invention a donc pour objet un procédé de raccordement de deux lés de tissu multicouche selon la revendication 1.The invention therefore relates to a method for connecting two multilayer fabric webs according to
Selon une caractéristique de l'invention, le moyen de liaison est une couture simple ou multiple reliant entre eux les voiles des deux lés adjacents.According to one characteristic of the invention, the means of binding is a single or multiple seam connecting the sails of the two adjacent strips.
Selon une autre caractéristique de l'invention, le moyen de liaison est appliqué entre les deux voiles des deux lès.According to another characteristic of the invention, the connecting means is applied between the two webs of both.
Selon encore une autre caractéristique de l'invention, le moyen de liaison est constitué par une fermeture à glissière interposée entre les voiles des deux lés adjacents.According to yet another characteristic of the invention, the connecting means is constituted by a slide fastener interposed between the webs of the two adjacent strips.
Selon encore une autre caractéristique de l'invention, chaque lé peut présenter au niveau du bord libre trois voiles libres à deux dimensions de tissu intercalés entre eux.According to yet another characteristic of the invention, each web may have at the free edge three webs free two-dimensional fabric interposed between them.
Selon encore une autre caractéristique, chaque lé présente deux voiles libres intercalés entre eux dont l'un à deux dimensions et l'autre à trois dimensions.According to yet another characteristic, each lé has two free sails interposed between them one of which has two dimensions and the other three dimensions.
Selon encore une autre caractéristique, chaque lé présente cinq voiles à deux dimensions intercalés entre eux.According to yet another characteristic, each lé has five two-dimensional sails interposed between them.
L'invention concerne également un procédé de protection électromagnétique d'un abri technique mobile ou d'une tente caractérisé en ce qu'on réalise une enveloppe épousant la forme extérieure de l'abri technique ou de la tente au moyen de plusieurs lés en tissu présentant des propriétés de protection électromagnétique en les assemblant ensemble par un procédé de raccordement tel que décrit précédemment.The invention also relates to a method of electromagnetic protection of a mobile technical shelter or a tent, characterized in that an envelope is produced which matches the outer shape of the technical shelter or the tent by means of several fabric webs. having electromagnetic protection properties by assembling them together by a connection method as described above.
Un tout premier avantage du précédé selon l'invention réside dans la possibilité de fabriquer des tissus de longueur quelconque tout en conservant ses propriétés d'atténuation électromagnétique.A first advantage of the above according to the invention lies in the ability to fabricate any length of tissue while maintaining its electromagnetic attenuation properties.
Un autre avantage de l'invention réside dans la conservation des propriétés de résistance du tissu.Another advantage of the invention lies in the preservation of the strength properties of the fabric.
Un autre avantage encore réside dans la simplicité de raccordement des différents lés de tissus en utilisant les machines de tissage existantes, donc sans obligation de modifier ces machines.Yet another advantage lies in the simplicity of connection of the different fabric webs using the existing weaving machines, thus without any obligation to modify these machines.
Un autre avantage encore réside dans la souplesse de la liaison ainsi réalisée, proche de celle des tissus unitaires.Another advantage lies in the flexibility of the bond thus produced, close to that of the unitary tissues.
D'autres caractéristiques, détails et avantages de l'invention ressortiront plus clairement de la description donnée ci-après à titre indicatif en relation avec des dessins dans lesquels :
- la figure 1 illustre le bord libre de deux lés de tissu après tissage,
- la figure 2 illustre le raccordement des deux lés selon la figure 1,
- les figures 3 à 5 illustrent le bord libre de deux autres lés de tissu.
- FIG. 1 illustrates the free edge of two fabric strips after weaving,
- FIG. 2 illustrates the connection of the two strips according to FIG.
- Figures 3 to 5 illustrate the free edge of two other fabric webs.
Le tissu dont on veut raccorder ensemble plusieurs lés de façon à obtenir une grande largeur est fabriqué sur des machines existantes. La nécessité de raccorder ces lés s'impose dès que l'on souhaite recouvrir de grandes surfaces. La longueur du lé peut être ajustée suivant la demande mais il n'en est pas de même de sa largeur puisqu'elle est fonction de la machine de tissage utilisée. Le mode de liaison s'avère important lorsque le tissu présente des propriétés électromagnétiques puisque celles-ci doivent être conservées pour un tissu quelles que soient ses dimensions. En effet, le tissu constitué de plusieurs lés assemblés entre eux peut constituer une structure ouverte permettant au champ magnétique d'interférer avec les appareils que l'on veut protéger, si la liaison entre les lés n'assure pas la continuité électrique ainsi que l'atténuation électromagnétique. Bien entendu les tissus selon l'invention sont des tissus présentant trois dimensions c'est-à-dire que le tissage est réalisé suivant les trois directions de l'espace pour conférer les propriétés électromagnétiques comme expliqué par le demandeur dans une demande antérieure de brevet.The fabric which is to be joined together several strips so as to obtain a large width is manufactured on existing machines. The need to connect these strips is required as soon as it is desired to cover large areas. The length of the lé can be adjusted according to the demand but it is not the same of its width since it depends on the weaving machine used. The mode of binding is important when the fabric has electromagnetic properties since they must be preserved for a fabric regardless of its size. Indeed, the fabric consisting of several strips assembled together may constitute an open structure allowing the magnetic field to interfere with the devices that we want to protect, if the connection between the strips does not ensure electrical continuity and the electromagnetic attenuation. Of course, the fabrics according to the invention are fabrics having three dimensions, that is to say that the weaving is performed along the three directions of space to confer the electromagnetic properties as explained by the applicant in an earlier patent application. .
C'est pourquoi selon l'invention, on réalise un tissage de chaque lé 1 ou 2 en trois dimensions et on forme comme représenté sur la figure 1 deux voiles. Le lé 1 comporte un premier voile 3 à deux dimensions et un second voile 4 à trois dimensions. De même, le lé 2 comprend le long de son bord libre un voile 5 à deux dimensions et un voile 6 à trois dimensions. Le tissu représenté sur cette figure comporte trois couches tissées ensembles dans une structure à trois dimensions. Ce tissage ne présente aucune difficulté car il suffit d'arrêter le tissage 3D sur une largeur suffisante au voisinage du bord libre pour une couche tout en la poursuivant pour les deux autres couches. Pour mémoire, on notera que le tissage 3D consiste à insérer suivant les trois directions de l'espace au cours du tissage un fil métallique suivant ces trois directions et, ce, sans aucune intervention ultérieure.This is why according to the invention, weaving of each
Bien entendu, le tissu dont on veut augmenter la largeur peut se présenter suivant deux couches, trois couches et plus suivant les impératifs techniques que l'on veut respecter.Of course, the fabric which is to increase the width may be in two layers, three layers and more depending on the technical requirements that we want to meet.
Pour éviter les fuites électriques, on insère entre eux suivant l'invention les voiles de chaque lé et sur la figure 2 on voit que l'on a engagé le voile 6 du lé 2 entre les voiles 3 et 4 du lé 1, le voile 5 du lé 2 venant s'appliquer contre le voile 4. Ces voiles sont maintenus ensembles à l'aide de tout moyen. Un premier moyen consiste à réaliser une couture simple ou multiple sur la largeur (d) de raccordement des deux lés 1 et 2. Un autre moyen consisterait à interposer entre le voile 3 et le lé 2 un moyen de liaison amovible 7 du type fermeture à glissière et un moyen du même type 8 entre le voile libre 5 et le lé 1. Ce moyen 7 ou 8 doit bien entendu assurer la continuité électrique du tissu obtenu selon l'invention. A cette fin, cette fermeture doit incorporer un matériau conducteur de l'électricité. L'atténuation électromagnétique est donc obtenue par la réalisation de chicanes entre chaque couche de tissu ainsi liée, permettant à l'onde électromagnétique de se propager de façon non uniforme dans le tissu pour augmenter d'autant l'atténuation.To avoid electric leakage, the sails of each lé are inserted between them according to the invention and in FIG. 2 it is seen that the
Sur la figure 3, on a représenté les deux lés 1 et 2 présentant au niveau de leur bord libre trois voiles à deux dimensions. Le lé 1 est prolongé par les voiles 9, 10 et 11 et le lé 2 par les voiles 12, 13 et 14. Pour constituer la structure 3D on intercale par exemple le voile 14 entre les voiles 10 et 11 et le voile 9 entre les voiles 12 et 13, puis on réalise une couture à l'aide d'un fil conducteur ou non de ces six couches entre elles.In Figure 3, there is shown the two
Sur la figure 4, on a représenté un lé 15 à trois dimensions constitué de quatre couches de tissu dont le bord libre présente deux voiles 16 et 17. Chacun de ces voiles est constitué de deux couches suivant une structure à trois dimensions. Pour réunir deux lés de même configuration, on intercale les voiles entre eux comme expliqué précédemment et on réalise soit en emprisonnant les quatre voiles par une couture soit interposant une fermeture à glissière entre les voiles externes et le lé correspondant.FIG. 4 shows a three-dimensional web consisting of four fabric layers whose free edge has two
Sur la figure 5, on a représenté un lé 18 à trois dimensions, constitué de cinq couches de tissu. Au niveau du bord libre de ce lé les cinq couches sont tissées séparément pour constituer cinq voiles 19-23 à deux dimensions. Pour réunir deux lés adjacents on intercale comme expliqué précédemment les voiles respectifs entre eux, puis on réalise par exemple une couture entre les dix voiles ainsi assemblés.In Figure 5, there is shown a three-
Un tissu de grande dimension obtenu selon la présente invention permet une utilisation tout à fait adéquate pour la réalisation de protections de tout type de structures émettant un rayonnement électromagnétique ou sujet à l'influence du rayonnement électromagnétique. Le tissu permet d'atténuer ce rayonnement quel que soit son sens. A titre d'illustration, on peut recouvrir un abri technique mobile classique à l'aide d'une enveloppe épousant la forme extérieure de l'abri. On peut également à l'inverse tapisser les parois intérieures de l'abri technique à l'aide du tissu selon l'invention. Le tissu selon l'invention peut être également simplement combiné avec un cadre en assemblant plusieurs lés ensembles et protéger ainsi de façon rapide les matériels disposés dans ledit cadre. Le tissu peut être utilisé simplement comme une protection électromagnétique dans une toile de tente.A large-size fabric obtained according to the present invention allows a use quite adequate for the realization of protections of any type of structures emitting electromagnetic radiation or subject to the influence of electromagnetic radiation. The fabric helps to reduce this radiation regardless of its meaning. By way of illustration, a conventional mobile technical shelter can be covered by means of an envelope matching the outer shape of the shelter. It is also possible to reverse the interior walls of the technical shelter with the aid of the fabric according to the invention. The fabric according to the invention can also be simply combined with a frame by assembling several strips together and thus quickly protect the materials arranged in said frame. The fabric can be used simply as an electromagnetic shield in a tent.
