Domaine techniqueTechnical area
La présente invention a trait à un nouveau type de matériau complexe à base d'une structure textile, tissu notamment, associé à une couche de matière thermoplastique telle que feuille de polyoléfine, polyéthylène notamment.The present invention relates to a new type of complex material based on a textile structure, in particular fabric, associated with a layer of thermoplastic material such as polyolefin sheet, in particular polyethylene.
De tels articles sont notamment utilisés comme matériaux de revêtement, notamment dans le domaine de l'ameublement, pour le revêtement de sièges de véhicules, le revêtement de parois internes de ces derniers, par exemple des tableaux de bord, parois de portes, pavillons de toitures, bagagerie ... .Such articles are used in particular as coating materials, in particular in the field of furniture, for the coating of vehicle seats, the coating of the internal walls of the latter, for example dashboards, door walls, headlamps. roofs, luggage ...
Techniques antérieuresPrevious techniques
Il a été proposé depuis des décennies, ainsi que cela ressort notamment du brevet US 3 470 055 ou du brevet GB 940 704, de réaliser des structures complexes en associant une structure textile tel que notamment un non-tissé, un tissu, un tricot à un film thermoplastique tel que notamment un film de PVC ou de polyoléfine, polyéthylène notamment.It has been proposed for decades, as is apparent in particular from US patent 3,470,055 or from patent GB 940,704, to produce complex structures by associating a textile structure such as in particular a nonwoven, a fabric, a knitted fabric. a thermoplastic film such as in particular a PVC or polyolefin film, especially polyethylene.
Il a également été proposé, comme cela ressort du FR 2 583 339, de réaliser des structures textiles enduites d'une matière plastique, par association du support textile tel qu'un tissu, tricot, non-tissé, avec un film, l'association étant réalisée en continu par calandrage de ces deux éléments à la sortie de la filière d'extrusion, ce qui présente un grand intérêt en ce qui concerne les cadences de production.It has also been proposed, as is apparent from FR 2,583,339, to produce textile structures coated with a plastic material, by association of the textile support such as a fabric, knitted fabric, non-woven fabric, with a film, the association being carried out continuously by calendering these two elements at the outlet of the extrusion die, which is of great interest with regard to production rates.
D'une manière générale, dans un tel procédé, on utilise une calandre comportant un cylindre revêtu d'une couche de caoutchouc (ou similaire), l'autre cylindre étant, quant à lui, en acier et sa surface étant grainée afin de donner à l'article produit un état de surface qui contribue non seulement à l'aspect esthétique, en imitant par exemple les matériaux naturels tels que le cuir, mais également évite que l'article soit glissant et/ou collant lorsqu'il est utilisé en tant que revêtement de sièges ou de parois, notamment dans le domaine de l'automobile ou de l'ameublement.Generally, in such a method, a calender is used comprising a cylinder coated with a layer of rubber (or the like), the other cylinder being, in turn, made of steel and its surface being grained in order to give at the article produces a surface finish which not only contributes to the aesthetic appearance, for example by imitating natural materials such as leather, but also prevents the article from being slippery and / or sticky when used as as seat or wall covering, in particular in the automotive or furniture sector.
D'une manière générale, et ainsi que cela ressort du document FR 2.583.339, pour réaliser le complexe, on associe le support textile avec un film destiné à constituer l'enduit support superficiel directement à la sortie de l'installation de production d'un tel film. De manière connue, l'association de ces deux éléments est réalisée au moyen d'une calandre comportant un rouleau lisse en acier et un contre rouleau caoutchouté. Selon ce document :In general, and as is apparent from document FR 2,583,339, in order to produce the complex, the textile support is associated with a film intended to constitute the surface support coating directly at the outlet of the production installation d 'such a film. In known manner, the association of these two elements is carried out by means of a calender comprising a smooth steel roller and a rubberized counter roller. According to this document:
- lors de la superposition, le tissu est en contact avec le rouleau lisse en acier alors que le film est en contact avec le rouleau caoutchouté ; - le film est étiré dans la zone comprise entre la sortie de la filière et la ligne de jonction entre les rouleaux de la calandre ; et- during the superposition, the fabric is in contact with the smooth steel roller while the film is in contact with the rubberized roller; - the film is stretched in the area between the outlet of the die and the junction line between the rollers of the calender; and
- lors de la superposition, le film est à une température voisine de sa température en sortie de filière.- during the superposition, the film is at a temperature close to its temperature at the outlet of the die.
L'étirage du film entre la filière et la ligne de jonction est obtenu en réglant de manière appropriée la vitesse des rouleaux de la calandre, cet étirage étant réalisé sur une très courte distance, de l'ordre de cinq centimètres, la température du film ne s'abaissant que faiblement sur ce trajet et étant notamment de l'ordre de 200°C au moment de la superposition avec le tissu support. Eventuellement, le tissu support peut également être préchauffé.The stretching of the film between the die and the junction line is obtained by appropriately adjusting the speed of the rollers of the calender, this stretching being carried out over a very short distance, of the order of five centimeters, the temperature of the film only lowering slightly on this path and being in particular of the order of 200 ° C at the time of superposition with the support fabric. Optionally, the support fabric can also be preheated.
Par ailleurs, pour une bonne mise en œuvre de l'invention, le cylindre caoutchouté doit être souple en surface afin de permettre l'enfoncement du tissu et la mise en forme du film lors de la liaison. Après passage entre la calandre et la liaison du tissu et du film, le complexe formé est refroidi puis réceptionné, par exemple sous forme d'un enroulement.Furthermore, for a good implementation of the invention, the rubberized cylinder must be flexible on the surface in order to allow the fabric to sink in and the film to be shaped during bonding. After passing between the calender and the connection of the fabric and the film, the complex formed is cooled and then received, for example in the form of a winding.
Grâce à un tel procédé, on obtient non seulement une liaison parfaite entre le film et le tissu, mais également, de manière automatique, un aspect graine correspondant à l'état de surface du tissu. Il est donc ainsi possible d'obtenir une multitude d'aspects par le simple choix de la contexture du tissu (ou tricot) support.Thanks to such a method, not only a perfect bond is obtained between the film and the fabric, but also, automatically, a seed appearance corresponding to the surface condition of the fabric. It is therefore possible to obtain a multitude of aspects by the simple choice of the texture of the support fabric (or knitted fabric).
Comme film thermoplastique, on peut utiliser tout matériau autre que leAs the thermoplastic film, any material other than
PVC pouvant adhérer sous l'action de la chaleur et de la pression au tissu support. Aussi, il peut être envisagé d'utiliser des films à base de polyuréthanne, polyéthylène, polypropylène, d'acétate de celluloses... . De tels films peuvent être soit colorés dans la masse, soit transparents. Lorsqu'ils sont transparents, il est possible d'utiliser des tissus préalablement décorés, par exemple par impression, qui seront donc visibles après formation du complexe.PVC which can adhere under the action of heat and pressure to the support fabric. Also, it can be envisaged to use films based on polyurethane, polyethylene, polypropylene, cellulose acetate, etc. Such films can be either mass-colored or transparent. When they are transparent, it is possible to use previously decorated fabrics, for example by printing, which will therefore be visible after formation of the complex.
Exposé de l'InventionStatement of the Invention
Or on a trouvé, et c'est ce qui fait l'objet de la présente invention, qu'il était possible, à partir d'une telle technologie, de réaliser un nouveau type de complexe comportant non seulement un textile support de base associé à un revêtement à base de matériau thermoplastique, polyéthylène notamment, mais qui, par ailleurs, comporte, pour réaliser le décor de surface, intégrée audit complexe, une structure textile ajourée intégrée elle-même lors de la production dudit complexe.Now it has been found, and this is what is the subject of the present invention, that it was possible, from such technology, to produce a new type of complex comprising not only an associated base support textile to a coating based on thermoplastic material, in particular polyethylene, but which, moreover, comprises, in order to produce the surface decoration, integrated into said complex, an openwork textile structure itself integrated during the production of said complex.
D'une manière générale, conformément à l'invention, le procédé tel que décrit dans le FR 2 583 339, est adapté et se caractérise en ce que le support textile de base est, dans cette forme de réalisation, associé avec le film destiné à constituer l'enduit superficiel toujours directement à la sortie de l'installation de production d'un tel film, ladite association étant réalisée au moyen d'une calandre comportant un rouleau lisse en acier et un contre rouleau caoutchouté. Dans cette forme de réalisation, le support textile de base continu qui peut être un tissu, un non-tissé ou un tricot fermé, est amené contre les rouleaux de la calandre en étant en contact avec le rouleau caoutchouté.In general, in accordance with the invention, the method as described in FR 2 583 339 is suitable and is characterized in that the basic textile support is, in this embodiment, associated with the film intended to constitute the surface coating always directly at the outlet of the installation for producing such a film, said association being carried out by means of a calender comprising a smooth steel roller and a rubberized counter roller. In this embodiment, the continuous basic textile support which can be a fabric, a nonwoven or a closed knit, is brought against the rollers of the calender while being in contact with the rubberized roller.
Dans la nouvelle structure conforme à l'invention, une seconde structure textile destinée à former le décor, structure constituée par un textile ajouré tel qu'un tricot chaîne ou Rachel à mailles jetées, est amenée simultanément au niveau de la calandre en étant quant à lui en contact avec le cylindre lisse.In the new structure according to the invention, a second textile structure intended to form the decoration, structure constituted by an openwork textile such as a warp knitted fabric or Rachel with knitted stitches, is brought simultaneously to the level of the grille while being him in contact with the smooth cylinder.
Comme dans les enseignements des documents antérieurs, lors de la superposition, le film est à une température voisine de sa température en sortie de filière.As in the teachings of the previous documents, during the superposition, the film is at a temperature close to its temperature at the outlet of the die.
De même, l'étirage du film entre la filière et la ligne de jonction est obtenu en réglant de manière appropriée la vitesse des rouleaux de la calandre, cet étirage étant réalisé sur une très courte distance, de l'ordre de cinq centimètres, la température du film ne s'abaissant que faiblement sur ce trajet par rapport à sa température en sortie de l'extrudeuse.Similarly, the stretching of the film between the die and the junction line is obtained by appropriately adjusting the speed of the rollers of the calender, this stretching being carried out over a very short distance, of the order of five centimeters, the temperature of the film decreasing only slightly on this path compared to its temperature at the outlet of the extruder.
Pour la bonne mise en œuvre du procédé, afin d'obtenir un article conforme à l'invention, le textile ajouré qui est destiné à former le décor, est alimenté à une vitesse légèrement inférieure à la vitesse d'appel au travers des cylindres de la calandre.For the proper implementation of the method, in order to obtain an article in accordance with the invention, the openwork textile which is intended to form the decoration, is fed at a speed slightly lower than the speed of call through the cylinders of the grille.
A titre indicatif, cette vitesse est inférieure d'environ 2 à 3 % de la vitesse d'appel de la calandre.As an indication, this speed is approximately 2 to 3% lower than the call speed of the radiator grille.
Par ailleurs, pour obtenir une bonne association des différentes couches entre elles, l'écartement entre les cylindres de la calandre est réglé de manière à ce qu'une pression de l'ordre d'environ cinq bars s'exerce sur toute la largeur du complexe. En procédant d'une telle manière, on obtient donc un nouveau type de complexe, particulièrement adapté pour réaliser des revêtements de sièges, notamment pour automobiles, lequel textile support continu sert de base et est par exemple associé à la couche supérieure de la structure formant le siège, alors que le décor est obtenu par le mariage d'une part du film extrudé, et d'autre part, par le textile ajouré de surface qui est partiellement noyé dans l'épaisseur de ce film.Furthermore, to obtain a good association of the different layers with one another, the spacing between the cylinders of the calender is adjusted so that a pressure of the order of about five bars is exerted over the entire width of the complex. By proceeding in this way, a new type of complex is therefore obtained, particularly suitable for producing seat coverings, in particular for cars, which continuous textile support serves as a base and is for example associated with the upper layer of the structure forming the seat, while the decoration is obtained by the marriage on the one hand of the extruded film, and on the other hand, by the perforated surface textile which is partially embedded in the thickness of this film.
Le textile ajouré confère donc certains effets de relief à l'ensemble qu'il forme avec le film plastique.Openwork textile therefore gives certain relief effects to the assembly which it forms with the plastic film.
Il est donc possible d'obtenir des nouveaux complexes qui combinent et "marient" des effets textiles et les effets obtenus par la matière thermoplastique, notamment à base de polyéthylène ou polypropylène, apportant la richesse des décors de ces deux matériaux.It is therefore possible to obtain new complexes which combine and "marry" textile effects and the effects obtained by the thermoplastic material, in particular based on polyethylene or polypropylene, bringing the richness of the decorations of these two materials.
Description sommaire des dessinsBrief description of the drawings
La figure unique annexée illustre la manière dont est adapté le procédé faisant l'objet du FR 2.583.339 pour obtenir un nouveau type de complexe conforme à l'invention, cette figure étant une vue schématique, en bout, montrant comment est réalisée la succession des différents constituants.The single appended figure illustrates the way in which the process which is the subject of FR 2,583,339 is adapted to obtain a new type of complex in accordance with the invention, this figure being a schematic view, at the end, showing how the succession is carried out of the different constituents.
Manière de réaliser l'inventionWay of realizing the invention
En se reportant à la figure annexée, le nouveau complexe conforme à l'invention est donc réalisé sur une installation qui comporte une tête d'extrusion (1) conventionnelle, permettant de former un film par exemple à base d'une composition de matière plastique du type TPO. En dessous de cette tête d'extrusion (1), est disposée une calandre désignée par la référence générale (3), calandre constituée de deux cylindres (4,5), entraînés en rotation à une vitesse déterminée et maintenus avec un léger écart l'un par rapport à l'autre, tout en maintenant une pression contre les matériaux amenés entre les cylindres de cette calandre. Le cylindre (4) est un cylindre en acier à surface lisse. En revanche, le cylindre (5) est un cylindre revêtu d'une couche de caoutchouc (6) souple, elle-même siliconée. Par rapport aux enseignements du document FR 2.583.338, le support textile (7), constitué par un tissu ou tricot, est amené entre les cylindres (4,5) de manière à être en contact avec le cylindre caoutchouté (5).Referring to the appended figure, the new complex according to the invention is therefore produced on an installation which comprises a conventional extrusion head (1), making it possible to form a film, for example based on a plastic composition. of the TPO type. Below this extrusion head (1), is arranged a calender designated by the general reference (3), calender consisting of two cylinders (4,5), driven in rotation at a determined speed and maintained with a slight difference l relative to each other, while maintaining pressure against the materials brought between the cylinders of this calender. The cylinder (4) is a smooth surface steel cylinder. On the other hand, the cylinder (5) is a cylinder coated with a layer of flexible rubber (6), itself silicone. Compared to the teachings of document FR 2.583.338, the textile support (7), constituted by a fabric or knitted fabric, is brought between the cylinders (4,5) so as to be in contact with the rubberized cylinder (5).
Une seconde structure textile constituée par un matériau ajouré, tel que notamment une structure du type filet réalisée sur un métier à mailles jetées, notamment de type Rachel, est, quant à elle, amenée au niveau du cylindre lisse en acier (4). Cette seconde structure textile (10) est délivrée par l'intermédiaire de cylindres (11) à une vitesse légèrement inférieure à la vitesse périphérique des rouleaux de la calandre (4,5), l'écart de vitesse étant en général de l'ordre de 2 à 3 %.A second textile structure constituted by an openwork material, such as in particular a structure of the net type produced on a loom, in particular of the Rachel type, is, in turn, brought to the level of the smooth steel cylinder (4). This second textile structure (10) is delivered by means of cylinders (11) at a speed slightly lower than the peripheral speed of the rollers of the calender (4,5), the speed difference being generally of the order from 2 to 3%.
D'une manière similaire aux enseignements du brevet précité, la distance comprise entre la sortie (8) de l'extrudeuse (1) et la ligne de pincement (9) entre les trois constituants support textile (7), film (2) et textile ajouré de décor (10), est telle que le film ne subisse qu'un faible refroidissement dans cette zone. Une distance de l'ordre de cinq centimètres entre cette sortie convient et permet de conserver au film une température voisine de 200°C au moment de la jonction dans le cas de l'extrusion d'un film à base de polyoléfine. Bien entendu, comme dans le document précité, des moyens additionnels de chauffage pourraient être prévus pour maintenir cette température dans l'hypothèse où la tête d'extrusion serait plus éloignée des cylindres de la calandre.In a similar manner to the teachings of the aforementioned patent, the distance between the outlet (8) of the extruder (1) and the pinch line (9) between the three constituents of the textile support (7), film (2) and openwork textile decoration (10), is such that the film undergoes only a slight cooling in this area. A distance of the order of five centimeters between this outlet is suitable and allows the film to be kept at a temperature in the region of 200 ° C at the time of joining in the case of the extrusion of a polyolefin-based film. Of course, as in the aforementioned document, additional heating means could be provided to maintain this temperature in the event that the extrusion head is further from the cylinders of the calender.
Par ailleurs, conformément aux enseignements de l'état de la technique, la vitesse de rotation des cylindres (4) ou (5) est telle que l'on étire fortement le film entre la zone de sortie (8) de l'extrudeuse et la zone de pincement. A titre indicatif, si le film est à base de polyoléfine et a une épaisseur de 0,8 mm en sortie de filière, l'étirage permet de ramener cette épaisseur à environ 0,350 à 0,400 mm au moment de la superposition. ExempleFurthermore, in accordance with the teachings of the state of the art, the speed of rotation of the cylinders (4) or (5) is such that the film is stretched strongly between the exit zone (8) of the extruder and the pinch area. As an indication, if the film is based on polyolefin and has a thickness of 0.8 mm at the outlet of the die, stretching makes it possible to reduce this thickness to approximately 0.350 to 0.400 mm at the time of the superposition. Example
On réalise une structure complexe conforme à l'invention dans les conditions suivantes :A complex structure is produced in accordance with the invention under the following conditions:
• Textile support de base (7) constitué par un tissu chaîne et trame de coloris marron.• Base support fabric (7) consisting of a warp and weft fabric in brown color.
Ce tissu chaîne et trame est à base de coton et comporteThis warp and weft fabric is cotton-based and has
24 fils/centimètre en chaîne et 13 fils/centimètre en trame.24 threads / centimeter in warp and 13 threads / centimeter in weft.
La masse surfacique de ce tissu textile de base (7) est de 1850 g/m ,The surface mass of this basic textile fabric (7) is 1850 g / m,
• Le film (2) est quant à lui un film de polyoléfine extrudé à une vitesse de 4 m/min, ayant une épaisseur de 0,8 mm en sortie de l'extrudeuse.• The film (2) is a polyolefin film extruded at a speed of 4 m / min, having a thickness of 0.8 mm at the outlet of the extruder.
Ce film est étiré de 2 fois à la sortie de l'extrudeuse et après étirage, au moment de l'association avec le textile support de base (7), pèse 350 g/m2' Ce film est teinté, par exemple dans un coloris alu métal.This film is stretched 2 times at the outlet of the extruder and after stretching, at the time of association with the base support textile (7), weighs 350 g / m 2 '. This film is tinted, for example in a aluminum metal color.
Conformément à l'invention, simultanément à l'opération d'extrusion et d'association avec le textile support de base, on amène sur le cylindre en acier lisse (4) un textile ajouré (10), constitué par un tricotage chaîne à base de polyester, constitué de fils ayant un titre de 100 dtex et formant des jours de forme hexagonale, dont chaque côté a une longueur de 1 mm environ.In accordance with the invention, simultaneously with the extrusion and association operation with the base support textile, an openwork textile (10) is formed on the smooth steel cylinder (4), constituted by a warp knitting based on of polyester, consisting of threads having a count of 100 dtex and forming days of hexagonal shape, each side of which has a length of approximately 1 mm.
Ce textile ajouré est délivré par deux cylindres d'appel (11) tournant à une vitesse légèrement inférieure à la vitesse périphérique des cylindres (4,5) et, dans le cas présent, à une vitesse de 3,92 m/min.This openwork fabric is delivered by two call cylinders (11) rotating at a speed slightly lower than the peripheral speed of the cylinders (4,5) and, in this case, at a speed of 3.92 m / min.
La vitesse d'appel du complexe formé (12) par la calandre (4,5) est quant à elle de l'ordre de 4 m/min, permettant donc un étirage du film.The call speed of the complex formed (12) by the calender (4.5) is in the order of 4 m / min, thus allowing stretching of the film.
Par ailleurs, les rouleaux (4,5) sont réglés de manière à exercer une pression de cinq bars sur toute la largeur du complexe selon la zone de pincement. En sortie de la calandre, on obtient une structure complexe comportant un textile support de base constitué par le tissu (7) recouvert par une face d'aspect constituée par la combinaison du film de polyoléfine extrudé (2) et du textile ajouré (10) qui est noyé en surface de cedit film tout en restant apparent.Furthermore, the rollers (4,5) are adjusted so as to exert a pressure of five bars over the entire width of the complex according to the nipping area. At the outlet of the grille, a complex structure is obtained comprising a basic support textile constituted by the fabric (7) covered by an aspect face. constituted by the combination of the extruded polyolefin film (2) and the openwork fabric (10) which is embedded on the surface of said film while remaining visible.
Un tel matériau complexe peut être utilisé notamment comme revêtement de sièges, est très résistant, présente un aspect original combinant à la fois l'aspect textile donné par le textile ajouré (10) et l'aspect coloré donné par le film extrudé (2).Such a complex material can be used in particular as a seat covering, is very resistant, has an original appearance combining both the textile appearance given by the openwork fabric (10) and the colored appearance given by the extruded film (2). .
Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation décrit précédemment, mais elle en couvre toutes les variantes réalisées dans le même esprit. Of course, the invention is not limited to the embodiment described above, but it covers all the variants produced in the same spirit.
