Description

Textile de renfort comprenant un réseau de fils Reinforcement textile comprising a network of threads
L'invention concerne un textile de renfort, deux types de textiles composites comprenant un tel textile de renfort, ainsi qu'un vêtement notamment de protection comprenant de tels textiles composites.The invention relates to a reinforcing textile, two types of composite textiles comprising such a reinforcing textile, as well as in particular protective clothing comprising such composite textiles.
Pour la réalisation de vêtements notamment de protection, il est connu d'utiliser un empilement de couches ayant différentes fonctions de sorte à obtenir les performances globales souhaitées pour lesdits vêtements.For the production of clothing, in particular protective clothing, it is known to use a stack of layers having different functions so as to obtain the overall performance desired for said clothing.
En particulier, dans certaines applications, il peut être nécessaire d'utiliser une couche textile de renfort qui est notamment destinée à améliorer les propriétés de résistance mécanique de l'empilement utilisé, notamment en terme de résistance à l'abrasion, de résistance à la déchirure et de stabilité dimensionnelle lors de l'utilisation ou des différents lavages que le vêtement aura à subir.In particular, in certain applications, it may be necessary to use a reinforcing textile layer which is in particular intended to improve the mechanical resistance properties of the stack used, in particular in terms of abrasion resistance, resistance to tear and dimensional stability during use or different washes that the garment will have to undergo.
En outre, dans le cas de vêtements de protection thermique, tels que ceux utilisés par les pompiers, par les militaires ou dans l'industrie, il peut être également souhaitable que le textile de renfort contribue aux performances thermiques globales du vêtement.In addition, in the case of thermal protective clothing, such as that used by firefighters, by the military or in industry, it may also be desirable for the reinforcing textile to contribute to the overall thermal performance of the garment.
Une des contraintes qui se pose dans le domaine des textiles de renfort concerne l'optimisation de leur masse surfacique par rapport à leurs performances de renforcement.One of the constraints which arises in the field of reinforcement textiles relates to the optimization of their surface mass with respect to their reinforcement performance.
En effet, la couche textile de renfort venant s'ajouter aux autres couches formant l'empilement, il est souhaitable de minimiser sa masse surfacique de sorte à ne pas alourdir le vêtement, et ce en maximisant sa fonction de renforcement.Indeed, the reinforcing textile layer being added to the other layers forming the stack, it is desirable to minimize its surface mass so as not to weigh down the garment, and this by maximizing its reinforcement function.
L'invention vise donc notamment à proposer un textile de renfort qui remplit- de façon avantageuse la contrainte mentionnée ci-dessus. A cet effet, et selon un premier aspect, l'invention propose un textile de renfort comprenant un réseau de fils à haute ténacité, lesdits fils étant formés par l'association de microfibres de titre inférieur ou égal à 1 dtex et présentant un titre total inférieur ou égal à 100 dtex.The invention therefore aims in particular to propose a reinforcing textile which advantageously fulfills the constraint mentioned above. To this end, and according to a first aspect, the invention provides a reinforcing textile comprising a network of high tenacity yarns, said yarns being formed by the association of microfibers of titer less than or equal to 1 dtex and having a total titer less than or equal to 100 dtex.
Selon un deuxième aspect, l'invention propose un textile composite comprenant une couche textile et, associé sur elle, un tel textile de renfort.According to a second aspect, the invention provides a composite textile comprising a textile layer and, associated thereon, such a reinforcing textile.
Selon un troisième aspect, l'invention propose un textile composite comprenant une membrane imper-respirante et, associé sur elle, un tel textile de renfort.According to a third aspect, the invention provides a composite textile comprising a waterproof-breathable membrane and, associated on it, such a reinforcing textile.
Selon un quatrième aspect, l'invention propose un vêtement notamment de protection comprenant un textile composite pourvu d'une couche textile qui est disposée vers l'extérieur dudit vêtement.According to a fourth aspect, the invention provides a garment in particular for protection comprising a composite textile provided with a textile layer which is disposed towards the outside of said garment.
D'autres objets et avantages de l'invention apparaîtront au cours de la description qui suit en référence aux dessins annexés.Other objects and advantages of the invention will appear during the description which follows with reference to the accompanying drawings.
Les figures 1 à 3 sont des vues schématiques en élévation et à plat de trois réalisations d'un textile de renfort suivant l'invention.Figures 1 to 3 are schematic elevational and flat views of three embodiments of a reinforcing textile according to the invention.
Les figures 4 et 5 sont des vues schématiques en coupe de deux réalisations d'un textile composite suivant l'invention.Figures 4 and 5 are schematic sectional views of two embodiments of a composite textile according to the invention.
La figure 6 est une vue schématique en perspective d'un vêtement selon l'invention.Figure 6 is a schematic perspective view of a garment according to the invention.
En relation avec les figures 1 à 3, on décrit un textile de renfort 1 comprenant un réseau de fils 2 à haute ténacité. Par le terme « haute ténacité » on entend typiquement une ténacité supérieure à 10 cN/dtex, notamment supérieure à 15 cN/dtex. Les fils 2 sont formés par l'association, par exemple par une technique de filature classique, de microfibres de titre typiquement inférieur ou égal à 1 dtex, les fils ainsi obtenus ayant chacun un titre total inférieur ou égal à 100 dtex.In connection with FIGS. 1 to 3, a reinforcing textile 1 is described comprising a network of high tenacity yarns 2. The term “high tenacity” typically means a tenacity greater than 10 cN / dtex, in particular greater than 15 cN / dtex. The yarns 2 are formed by the association, for example by a conventional spinning technique, of microfibers with a titer typically less than or equal to 1 dtex, the yarns thus obtained each having a total titer less than or equal to 100 dtex.
Dans un exemple particulier, le réseau, notamment par sa densité et/ou par le titre des fils 2 qui le forme, présente une masse surfacique comprise entre 15 et 30 g/m2.In a particular example, the network, in particular by its density and / or by the title of the wires 2 which forms it, has a surface mass of between 15 and 30 g / m 2 .
Suivant la réalisation représentée sur la figure 1 , le textile de renfort 1 est réalisé sous la forme d'un tissu dont les fils de trame 2a et de chaîne 2b forment le réseau. En variante, selon les contraintes spécifiques de l'utilisation visée, il peut être prévu que seuls les fils de trame ou de chaîne constituent le réseau, les fils de chaîne respectivement de trame utilisés en combinaison étant de nature différente.According to the embodiment shown in FIG. 1, the reinforcing textile 1 is produced in the form of a fabric whose weft 2a and warp 2b threads form the network. As a variant, depending on the specific constraints of the intended use, it can be provided that only the weft or warp threads constitute the network, the respectively weft warp threads used in combination being of a different nature.
Suivant les réalisations représentées sur les figures 2 et 3, le textile de renfort 1 est réalisé sous la forme d'un tricot 3 dont la fonction principale n'est pas de procurer un renforcement mais plutôt de servir de support au réseau. Ainsi, le tricot 3 peut être réalisé avec des fils de ténacité standard, par exemple en polyester du type 22/1 dtex pour limiter le poids dudit tricot.According to the embodiments shown in Figures 2 and 3, the reinforcing textile 1 is produced in the form of a knitted fabric 3 whose main function is not to provide reinforcement but rather to serve as support for the network. Thus, knitting 3 can be produced with standard tenacity yarns, for example polyester of the 22/1 dtex type to limit the weight of said knitting.
Suivant la réalisation représentée sur la figure 2, le réseau est formé d'une insertion de fils de trame 2a qui sont disposés entre les rangées de mailles du tricot 3, lesdits fils de trame étant maintenus en place sur le tricot par les jetées 4 des fils de tricotage.According to the embodiment shown in FIG. 2, the network is formed by an insertion of weft threads 2a which are arranged between the rows of stitches of knitted fabric 3, said weft threads being held in place on the knitted fabric by the piers 4 of knitting yarn.
Suivant la réalisation représentée sur la figure 3, le réseau comprend en outre une insertion de fils de chaîne 2b qui sont disposés entre les colonnes de mailles du tricot 3, lesdits fils de chaîne étant également maintenus en place sur le tricot par les jetées 4 des fils de tricotage.According to the embodiment shown in FIG. 3, the network further comprises an insertion of warp threads 2b which are arranged between the knitted columns of knitted fabric 3, said warp threads also being held in place on the knitted fabric by the piers 4 of knitting yarn.
La fabrication du textile de renfort 1 suivant les réalisations représentées sur les figures 2 et 3 peut être obtenue par exemple en utilisant un métier de type « RACHEL ». A cet effet, on dépose entre la fronture et la plaque d'abattage les fils 2 à insérer dans le sens chaîne et/ou trame, de sorte qu'une ou plusieurs aiguilles coopèrent avec des barres à passettes pour réaliser le tricot maille 3 en insérant les fils 2 déposés.The manufacture of the reinforcing textile 1 according to the embodiments represented in FIGS. 2 and 3 can be obtained for example by using a loom of the type "RACHEL". To this end, the wires 2 to be inserted in the warp and / or weft direction are deposited between the front and the felling plate, so that one or more needles cooperate with guide bars to produce the knitted fabric 3 in inserting the 2 wires deposited.
Dans un exemple particulier, les microfibres sont réalisées à base d'un matériau choisi dans le groupe comprenant les para aramides, le verre, les polyéthylènes haute ténacité, les polybenzooxazoles, les poly-p- phenylènediamine-terephtalamides (PPTA ou M5).In a particular example, the microfibers are made from a material chosen from the group comprising para-aramids, glass, high-tenacity polyethylenes, polybenzooxazoles, poly-p-phenylenediamine-terephthalamides (PPTA or M5).
Le textile de renfort 1 selon l'invention présente donc, du fait du faible titrage des fils 2 formant le réseau, une masse surfacique faible, et qui est facilement ajustable en jouant sur la densité dudit réseau.The reinforcing textile 1 according to the invention therefore has, due to the low titration of the threads 2 forming the network, a low surface mass, and which is easily adjustable by varying the density of said network.
Le textile de renfort 1 suivant l'invention possède également des performances mécaniques particulièrement avantageuses qui sont obtenues grâce à la combinaison de la haute ténacité des fils 2 utilisés pour le réseau et de la structure ordonnée du réseau, à savoir qui s'étend dans une ou des direction(s) principale(s).The reinforcing textile 1 according to the invention also has particularly advantageous mechanical performances which are obtained thanks to the combination of the high tenacity of the threads 2 used for the network and the ordered structure of the network, namely which extends in a or main directorate (s).
Par ailleurs, la structure dimensionnelle du réseau permet de conserver une certaine élasticité au textile de renfort 1 , notamment dans les sens diagonaux lorsque le réseau s'étend dans les sens trame et chaîne, ce qui permet de conserver un porter agréable pour le vêtement comportant un tel textile de renfort 1.Furthermore, the dimensional structure of the network makes it possible to maintain a certain elasticity in the reinforcing textile 1, in particular in the diagonal directions when the network extends in the weft and warp directions, which makes it possible to maintain a pleasant wear for the garment comprising such a reinforcing textile 1.
En outre, l'utilisation de microfibres permet de donner une certaine pilosité de surface aux fils 2 du réseau, ce qui contribue, notamment lorsque le textile de renfort 1 est soumis à des efforts d'extension, à limiter le glissement des fils 2 dans le réseau.In addition, the use of microfibers makes it possible to give a certain surface hairiness to the threads 2 of the network, which contributes, in particular when the reinforcing textile 1 is subjected to extension forces, to limit the sliding of the threads 2 in the network.
Le textile de renfort 1 suivant l'invention permet donc d'obtenir un bon compromis entre les contraintes de masse surfacique et de propriété de renforcement, et ce de façon particulièrement modulable en fonction de l'application spécifique visée.The reinforcing textile 1 according to the invention therefore makes it possible to obtain a good compromise between the constraints of areal mass and of property of reinforcement, and this in a particularly flexible way depending on the specific application targeted.
Par ailleurs, la disposition des fils de renfort 2 sous la forme d'un réseau permet, contrairement à l'utilisation d'une maille, d'éviter la formation de nœuds qui conduirait à une fragilisation du textile de renfort 1. En effet, certains fils à haute ténacité 2 sont connus pour être relativement fragiles et donc à avoir tendance à se casser lorsqu'ils sont sollicités mécaniquement dans une direction transversale.Furthermore, the arrangement of the reinforcing threads 2 in the form of a network makes it possible, unlike the use of a mesh, to avoid the formation of knots which would lead to weakening of the reinforcing textile 1. In fact, certain high tenacity yarns 2 are known to be relatively fragile and therefore to have a tendency to break when they are mechanically stressed in a transverse direction.
Le textile de renfort 1 selon l'invention est particulièrement destiné à être associé à au moins une autre couche 5, 6 de sorte à renforcer le textile composite 7 ainsi obtenu.The reinforcing textile 1 according to the invention is particularly intended to be associated with at least one other layer 5, 6 so as to reinforce the composite textile 7 thus obtained.
Selon les réalisations schématisées sur la figure 4, le textile composite 7 comprend deux couches, à savoir une couche de textile de renfort 1 et une couche textile 5 ou une couche formée d'une membrane imper-respirante 6 - c'est-à-dire imperméable à l'eau liquide et au vent mais perméable à la vapeur d'eau, notamment à la sueur -.According to the embodiments shown diagrammatically in FIG. 4, the composite textile 7 comprises two layers, namely a layer of reinforcing textile 1 and a textile layer 5 or a layer formed of a waterproof-breathable membrane 6 - that is to say to say impermeable to liquid water and wind but permeable to water vapor, in particular to sweat -.
Dans deux exemples particuliers de réalisation, la membrane 6 peut être microporeuse et/ou hydrophilique et formée d'un matériau à base de polyuréthane ou à base de polytétrafluoroéthylène. Par ailleurs, la couche textile 5 peut être de tous types utilisés pour la réalisation d'un vêtement, par exemple sous la forme d'un tissu, d'un tricot ou d'un non-tissé.In two particular embodiments, the membrane 6 can be microporous and / or hydrophilic and formed from a material based on polyurethane or based on polytetrafluoroethylene. Furthermore, the textile layer 5 can be of all types used for the production of a garment, for example in the form of a fabric, a knitted fabric or a nonwoven.
L'association des deux couches peut être réalisée au moyen d'une couche d'adhésif, par exemple discontinue 8 qui est placée entre lesdites couches notamment par enduction sérigraphie de points adhésifs.The association of the two layers can be achieved by means of an adhesive layer, for example discontinuous 8 which is placed between said layers, in particular by screen printing coating of adhesive dots.
En variante de la réalisation dans laquelle la deuxième couche est textile, une enduction de mousse imper-respirante peut être disposée de façon connue sur le textile de renfort 1. En variante de la réalisation dans laquelle la deuxième couche est une membrane 6, une troisième couche formée d'un textile 5 peut être associée sur la membrane 6, par exemple au moyen d'une deuxième couche d'adhésif discontinue 8 (voir figure 5).As a variant of the embodiment in which the second layer is textile, a coating of waterproof-breathable foam can be placed in known manner on the reinforcing textile 1. As a variant of the embodiment in which the second layer is a membrane 6, a third layer formed of a textile 5 can be associated on the membrane 6, for example by means of a second discontinuous layer of adhesive 8 (see FIG. 5 ).
De façon générale, le textile de renfort 1 peut être utilisé dans d'autres types de textiles composites comprenant plusieurs couches, ledit textile de renfort étant inséré entre deux couches adjacentes de sorte à remplir sa fonction sans alourdir de façon notable le textile composite ainsi obtenu.In general, the reinforcing textile 1 can be used in other types of composite textiles comprising several layers, said reinforcing textile being inserted between two adjacent layers so as to fulfill its function without significantly weighing down the composite textile thus obtained. .
En outre, lorsque le textile de renfort 1 est réalisé sous la forme d'un tricot 3 tel que représenté sur les figures 2 ou 3, il est possible d'associer ledit tricot sur la couche 5, 6 par son coté sur lequel est disposé le réseau de sorte à améliorer le toucher et à ass rer une protection mécanique dudit réseau.In addition, when the reinforcing textile 1 is produced in the form of a knitted fabric 3 as shown in FIGS. 2 or 3, it is possible to associate said knitted fabric on the layer 5, 6 by its side on which is placed. the network so as to improve the feel and provide mechanical protection of said network.
Les textiles composites 7 peuvent être utilisés pour la réalisation de vêtements de protection, notamment de vêtements pour militaire, pour pompier ou utilisés dans l'industrie.The composite textiles 7 can be used for the production of protective clothing, in particular clothing for the military, for firefighters or used in industry.
Dans la réalisation représentée sur la figure 6, la couche textile 5 est disposée vers l'extérieur du vêtement, en l'occurrence une veste 9, de sorte que le textile de renfort 1 soit disposé vers le corps de l'utilisateur. Ainsi, en utilisant des fils de renfort 2 hydrophobes, on limite l'effet dit de mèche qui correspond au pompage de la transpiration par le textile composite 7. Par ailleurs, dans les cas où cela est souhaité, l'utilisation d'un réseau suffisamment ouvert permet d'étanchéifier efficacement les coutures du vêtement par disposition sur le textile de renfort 1 d'une bande de matériau thermoplastique et fusion partielle de ladite bande. En effet, la bande peut alors être associée efficacement au textile composite 7 en passant au travers du textile de renfort 1.In the embodiment shown in Figure 6, the textile layer 5 is disposed towards the outside of the garment, in this case a jacket 9, so that the reinforcing textile 1 is disposed towards the body of the user. Thus, by using hydrophobic reinforcing threads 2, the so-called wicking effect which corresponds to the pumping of perspiration by the composite textile 7 is limited. Furthermore, in the cases where this is desired, the use of a network sufficiently open makes it possible to effectively seal the seams of the garment by placing a strip of thermoplastic material on the reinforcing textile 1 and partial melting of said strip. Indeed, the strip can then be effectively associated with the composite textile 7 by passing through the reinforcing textile 1.
En outre, l'impression ou la teinture du textile de renfort 1 aux couleurs du textile composite 2 n'est alors pas nécessaire, ce qui est particulièrement avantageux du fait que les fils à haute ténacité 2 sont connus pour être très contraignants dans ce domaine. De plus, le textile de renfort 1 n'est pas exposé directement à la lumière, ce qui, notamment en cas d'utilisation de microfibres en para aramide, est particulièrement avantageux du fait de la sensibilité mécanique de ce matériau aux ultraviolets.In addition, the printing or dyeing of the reinforcing textile 1 in the colors of the composite textile 2 is then not necessary, which is particularly advantageous because the high tenacity yarns 2 are known to be very restrictive in this area. In addition, the reinforcing textile 1 is not exposed to direct light, which, in particular when using para-aramid microfibers, is particularly advantageous due to the mechanical sensitivity of this material to ultraviolet light.
Par ailleurs, l'utilisation d'une couche de textile de renfort 1 distincte de la couche textile 5 permet de simplifier la réalisation du textile composite 7 et de ne pas altérer l'aspect extérieur de ladite couche textile.Furthermore, the use of a reinforcing textile layer 1 distinct from the textile layer 5 makes it possible to simplify the production of the composite textile 7 and not to alter the external appearance of said textile layer.
Dans une application particulière, le textile composite 7 est destiné à la réalisation de vêtement de pompier qui doit présenter notamment des propriétés anti-feu.In a particular application, the composite textile 7 is intended for the production of firefighter clothing which must in particular have fire-fighting properties.
A cet effet, le réseau est réalisé à base d'un matériau anti-feu, tel que les meta aramides ou les polyamide-imides, la membrane 6 ou la mousse imper- respirante est ininflammable, les microfibres sont thermostables et réalisées à base d'un matériau ininflammable.For this purpose, the network is made from a fire-resistant material, such as meta aramides or polyamide-imides, the membrane 6 or the breathable foam is non-flammable, the microfibers are thermostable and made from '' a non-flammable material.
Dans le mode de réalisation où le support de renfort 1 comprend un tricot 3, ledit tricot est par exemple réalisé en polyester ignifugé de type TREVIRA CS.In the embodiment where the reinforcement support 1 comprises a knitted fabric 3, said knitted fabric is for example made of flame retardant polyester of the TREVIRA CS type.
Dans cette application particulière, le textile de renfort 1 permet en outre d'améliorer les propriétés thermiques du textile composite 7 lorsque le vêtement est soumis à une flamme ou à une source de chaleur importante.In this particular application, the reinforcing textile 1 also makes it possible to improve the thermal properties of the composite textile 7 when the garment is subjected to a flame or to a significant heat source.
En effet, dans le cas où le textile composite 7 est en partie détruit par l'exposition à la chaleur, le textile de renfort 1 garde sa structure dimensionnelle de sorte à améliorer la caractéristique dite de « break open » ou « d'éclatement à la chaleur » du vêtement. Il en résulte donc une moindre exposition de l'utilisateur à la chaleur. A titre d'exemple, on peut citer un textile composite 7 comprenant un couche textile formée d'un tissu en polyester de masse surfacique 170 g/m2, une membrane microporeuse en polyuréthanne de masse surfacique 20 g/m2 et un textile de renfort 1 sous la forme d'une grille tissée en para aramide de masse surfacique 20 g/m2. Ce tel textile composite 7 suivant l'invention présente une masse surfacique total de 210 g/m2 et une résistance à la déchirure comprise entre 12 et 15 daN.In fact, in the case where the composite textile 7 is partially destroyed by exposure to heat, the reinforcing textile 1 retains its dimensional structure so as to improve the characteristic known as “break open” or “bursting at the heat ”of the garment. This therefore results in less exposure of the user to heat. By way of example, there may be mentioned a composite textile 7 comprising a textile layer formed of a polyester fabric with a surface mass of 170 g / m 2 , a microporous polyurethane membrane with a surface mass of 20 g / m 2 and a textile of reinforcement 1 in the form of a woven grid of para aramid with a surface mass of 20 g / m 2 . This such composite textile 7 according to the invention has a total surface mass of 210 g / m 2 and a tear strength of between 12 and 15 daN.
A titre d'exemple comparatif, un textile composite comprenant les mêmes deux premières couches et un textile de renfort sous la forme d'un tricot maille en polyester de masse surfacique 70 g/m2, présente une masse surfacique total de 260 g/m2 et une résistance à la déchirure de l'ordre de 5 daN. By way of comparative example, a composite textile comprising the same first two layers and a reinforcing textile in the form of a polyester knitted fabric with a surface mass of 70 g / m 2 has a total surface mass of 260 g / m 2 and a tear strength of the order of 5 daN.
