Abstract
Description
La présente invention a pour objet un procédé de finition d'articles multicouches incluant au moins une couche de mousse synthétique et en particulier, mais non exclusivement, de tissus collés sur mousse synthétique destinée notamment à la fabrication de housses pour sièges de véhicules automobiles. The subject of the present invention is a method of finishing multilayer articles including at least one layer of synthetic foam and in particular, but not exclusively, of fabrics bonded to synthetic foam intended in particular for the manufacture of seat covers for motor vehicles.
On sait qu'il est connu, pour donner aux tissus collés sur mousse synthétique un aspect confortable de rembourrage ou de matelassure, de réaliser des surpiqures qui provoquent l'écrasement de certaines parties du tissu de manière à former un dessin. En fait, cette technique contient ses propres limites résultant des caractéristiques des machines à surpiquer dont les écartements sont relativement fixes, ce qui conduit à une certaine monotonie. Au demeurant, ces machines ne permettent pas l'exécution de tous les dessins souhaitables. We know that it is known, to give fabrics glued to synthetic foam a comfortable aspect of padding or padding, to make stitching which causes the crushing of certain parts of the fabric so as to form a pattern. In fact, this technique contains its own limits resulting from the characteristics of topstitching machines whose spacings are relatively fixed, which leads to a certain monotony. Moreover, these machines do not allow the execution of all the desirable designs.
On a par ailleurs déjà proposé de mouler la mousse dans le tissu préalablement conformé selon des reliefs déterminés mais ce procédé est d'une mise en oeuvre assez lourde. It has moreover already been proposed to mold the foam in the fabric previously shaped according to determined reliefs, but this method is of quite heavy implementation.
Enfin, il est connu de réaliser des matériaux multicouches notamment en assemblant par collage ou par tout autre procédé et en particulier celui connu sous la désignation anglosaxonne de "foam back", plusieurs couches de mousse. Finally, it is known to produce multilayer materials in particular by assembling by bonding or by any other process and in particular that known under the Anglo-Saxon designation of "foam back", several layers of foam.
La présente invention a pour objet un procédé de finition permettant d'utiliser les caractéristiques physiques de l'une des couches constituant le matériau pour réaliser le décor voulu. The subject of the present invention is a finishing process making it possible to use the physical characteristics of one of the layers constituting the material to produce the desired decoration.
Selon la présente invention, le procédé de finition d'un matériau multicouche comprenant un substrat sur lequel est fixée une couche de mousse est caractérisé en ce que ladite couche de mousse est soumise à une pression et à une élévation de température correlative de manière à réaliser une fusion sélective de ladite couche selon le contour du dessin désiré. According to the present invention, the method of finishing a multilayer material comprising a substrate on which a layer of foam is fixed is characterized in that said layer of foam is subjected to a pressure and to a correlative rise in temperature so as to produce a selective fusion of said layer according to the outline of the desired design.
Ainsi, selon la présente invention, le dessin est formé sur le matériau par fusion de la mousse expansée. Thus, according to the present invention, the pattern is formed on the material by melting the expanded foam.
La présente invention a également pour objet les articles obtenus selon ce procédé. The present invention also relates to the articles obtained by this process.
D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre d'un mode de réalisation particulier, donné à titre d'exemple non limitatif, en regard des figures qui représentent
- les figures 1 à 3, les diverses étapes du procédé;
- la figure 4 une coupe partielle de l'article obtenu;
- la figure 5 le schéma d'un appareil de pose de colle;
- la figure 6 une variante de réalisation.Other characteristics and advantages of the invention will appear during the following description of a particular embodiment, given by way of nonlimiting example, with reference to the figures which represent
- Figures 1 to 3, the various stages of the process;
- Figure 4 a partial section of the article obtained;
- Figure 5 the diagram of an adhesive application device;
- Figure 6 an alternative embodiment.
Sur la figure 1, llarticle multicouches comporte un substrat 1 constitué par exemple dZune couche polyester/ polyuréthanne par exemple obtenue par action de polyesters à grande teneur en hydroxyle ayant réagi sur des isocyanates. In FIG. 1, the multilayer article comprises a substrate 1 consisting for example of a polyester / polyurethane layer, for example obtained by the action of polyesters with a high hydroxyl content which have reacted on isocyanates.
Le substrat 1 est réuni à la couche 2 constituée par de la mousse de polyéthylène par exemple, soit par foaming à une température de l' ordre de 11700, soit par adjonction d'une couche de colle 5.The substrate 1 is joined to the layer 2 constituted by polyethylene foam for example, either by foaming at a temperature of the order of 11700, or by the addition of a layer of glue 5.
De l'autre côté de la couche 2 est fixée également par foaming ou collage une couche 3 de mousse de polyuréthanne à laquelle adhère une couche de tissu 6. On the other side of the layer 2 is also fixed by foaming or gluing a layer 3 of polyurethane foam to which a layer of fabric 6 adheres.
Le matériau est disposé à plat au-dessous d'une presse 7. The material is placed flat below a press 7.
La figure 2 représente schématiquement l'opération de thermocompression selon le procédé. Dans l'exemple représenté, la presse 7 porte un profilé 8 creux définissant les contours du motif à obtenir. La pression appliquée est de l'ordre de 6 bars, la température sur l'empreinte 8 étant de l'ordre de 1500 environ. Au cours de cette opération, les cellules de mousse de la couche 2 sont soudées entre elles ou fondues par la thermocompression sans que la couche de polyuréthanne 1 soit altérée. Au bout d'un temps de l'ordre de 10 secondes, la déformation de la couche d'une mousse de polyéthylène 2 devient permanente et un relief en creux est formé sur le matériau, ce qui donne effectivement l'impression d'une surpiqure. Le résultat obtenu est représenté sur la figure 3 qui est une coupe selon la ligne III-III de la figure 4.On voit sur cette coupe que la thermocompression du contour 8 a créé des rainures creuses 9. FIG. 2 schematically represents the thermocompression operation according to the method. In the example shown, the press 7 carries a hollow profile 8 defining the contours of the pattern to be obtained. The pressure applied is of the order of 6 bars, the temperature on the imprint 8 being of the order of approximately 1500. During this operation, the foam cells of layer 2 are welded together or melted by thermocompression without the polyurethane layer 1 being damaged. After a time of the order of 10 seconds, the deformation of the layer of polyethylene foam 2 becomes permanent and a hollow relief is formed on the material, which effectively gives the impression of an overstitching. . The result obtained is shown in FIG. 3 which is a section along line III-III in FIG. 4. It can be seen in this section that the thermocompression of the contour 8 has created hollow grooves 9.
Sur la figure 4 apparaît un contour 10 d'un motif pouvant être utilisé pour la finition d'une housse de voiture automobile par exemple. Bien entendu, ce motif dépend de la forme de l'empreinte 8. In FIG. 4 there appears an outline 10 of a pattern which can be used for the finishing of a motor vehicle cover, for example. Of course, this pattern depends on the shape of the imprint 8.
Bien entendu, les données qui ont été indiquées cidessus ne constituent qu'un exemple de mise en oeuvre de l'invention et il est évident que ce procédé peut s'appliquer à d'autres types de mousse que celles qui ont été men tonnées et en particulier aux mousses de chlorure de polyvinyle PVC ou d'acrylique0 La densité de la mousse de polyéthylène et l'épaisseur de celle-ci sont fonction de la profondeur du marquage recherché. Dans l'exemple ci-dessus, les mousses utiliséessétaient des mousses dont la densité variait de 27 à 30 mais le procédé est applicable aux mousses de polyéthylène de densité comprise entre 18 et 60 et aux mousses de polyuréthannes de densité comprise entre 22 et 100. Les paramètres de la thermocompression sont bien entendu adaptés à l'épaisseur et la nature du matériau à traiter. Of course, the data which have been indicated above constitute only one example of implementation of the invention and it is obvious that this process can be applied to other types of foam than those which have been mentioned and in particular to polyvinyl chloride PVC or acrylic foams. The density of the polyethylene foam and the thickness thereof depends on the depth of the marking sought. In the example above, the foams used were foams with a density varying from 27 to 30 but the process is applicable to polyethylene foams with a density between 18 and 60 and polyurethane foams with a density between 22 and 100. The parameters of thermocompression are of course adapted to the thickness and the nature of the material to be treated.
Bien que dans l'exemple qui a été décrit précédemment, le substrat soit constitué par la couche de mousse, cette caractéristique n'est pas obligatoire et le substrat peut être rigide. Dans ce cas, une faible épaisseur de mousse à forte densité solidarisée du substrat peut permettre le marquage d'objets et le formage de ceux-ci comme on le fait par exemple avec des cartons dont la pliure a été préalablement marquée
Outre l'aspect décoratif obtenu, les matériaux réalisés selon le procédé présentent des qualités d'étanchéité à l'air et à l'eau et de légèreté qui permet son utilisation dans différents domaines tels que les revêtements muraux, l'isolation, etc.Although in the example which has been described previously, the substrate consists of the foam layer, this characteristic is not compulsory and the substrate can be rigid. In this case, a small thickness of high density foam secured to the substrate can allow the marking of objects and the forming thereof as is done for example with cartons whose fold has been previously marked
In addition to the decorative appearance obtained, the materials produced according to the process have airtightness and water tightness qualities and lightness which allows its use in various fields such as wall coverings, insulation, etc.
Les figures 5 et 6 sont relatives à un autre mode de réalisation de 11 invention. Comme cela apparaît sur la figure 6 le matériau multicouche est constitué dans ce cas de la façon suivante. Il comprend une couche de tissu décor 11 qui peut être foamée c'est-à-dire revêtue d'une couche 12 de mousse polyuréthanne assemblée par chauffage. Sur la couche de mousse 12 est disposé un film de polyéthylène du genre de celui connu dans le commerce sous l'appellation de "xiro".Ce film 13 est recouvert d'une couche d'ouate 14 par exemple d'ouate de polyester destiné à assurer le rembourrage du produit, la couche d'ouate 14 étant elle-même surmontée par une couche de mousse 15 imprégnée d'une poudre thermoplastique ou thermodurcissable et qui peut être par exemple une poudre de polyéthylène et d'acrylique du type connu dans la technique sous la désignation EVA. Figures 5 and 6 relate to another embodiment of the invention. As it appears in FIG. 6, the multilayer material is constituted in this case in the following way. It comprises a layer of decorative fabric 11 which can be foamed, that is to say coated with a layer 12 of polyurethane foam assembled by heating. On the foam layer 12 is disposed a polyethylene film of the kind known in the trade under the name of "xiro". This film 13 is covered with a layer of wadding 14, for example polyester wadding intended ensuring the padding of the product, the wadding layer 14 itself being surmounted by a layer of foam 15 impregnated with a thermoplastic or thermosetting powder and which may for example be a polyethylene and acrylic powder of the type known in the technique under the designation EVA.
L'imprégnation de la mousse 15 par la poudre 16 demande un certain nombre de précautions dans la mesure où il est nécessaire que les particules de poudre pénètrent à l'intérieur des cellules de la mousse. Il est possible d'appliquer la couche de poudre sur la mousse au moyen de brosses douces animées d'un mouvement de rotation avec une légère pression. Toutefois, il est avantageux de procéder de la façon suivante. The impregnation of the foam 15 with the powder 16 requires a certain number of precautions insofar as it is necessary for the powder particles to penetrate inside the cells of the foam. It is possible to apply the powder layer to the foam using soft brushes that rotate with slight pressure. However, it is advantageous to proceed as follows.
Sur la figure 5 on a représenté un rouleau de mousse polyuréthanne 15 qui est déroulé de manière à ce que la feuille de mousse passe à travers une boîte à poudre 17 entre deux paires de rouleaux 18 et 19 qui assurent un étirement de la feuille lors du passage dans la boite 17. In Figure 5 there is shown a polyurethane foam roller 15 which is unwound so that the foam sheet passes through a powder box 17 between two pairs of rollers 18 and 19 which ensure a stretching of the sheet during the passage in the box 17.
La boîte 17 présente à sa partie supérieure une trémie 20 d'introduction de la poudre alors qu'elle est munie à sa partie inférieure d'ouvertures permettant de récupérer dans un bac 21 la poudre non absorbée par la nappe de mousse, le bac 21 étant relié à la trémie d'introduction 20 un système de transport pneumatique (non représenté) qui permet le recyclage de la poudre non utilisée. Un raclette 22 assure un étalement à peu près uniforme de la couche de poudre introduite par la trémie 20. L'important est de bien faire pénétrer la poudre dans la masse de la mousse et à cet égard il est souhaitable de veiller à ce que la granulométrie de la poudre choisie soit compatible avec la dimension des cellules de la mousse utilisée. La pénétration de la poudre à l'intérieur de la mousse est obtenue par la double action d'étirement et de pression exercée par les jeux de rouleaux 18 et 19. Bien entendu ces actions mécani
ques sont limités par la résistance mécanique de la mousse
choisie.The box 17 has at its upper part a hopper 20 for introducing the powder while it is provided at its lower part with openings making it possible to recover in a container 21 the powder not absorbed by the sheet of foam, the container 21 being connected to the introduction hopper 20 a pneumatic transport system (not shown) which allows the recycling of the unused powder. A squeegee 22 ensures an almost uniform spreading of the layer of powder introduced by the hopper 20. The important thing is to make the powder penetrate well into the mass of the foam and in this regard it is desirable to ensure that the particle size of the chosen powder is compatible with the size of the cells of the foam used. The penetration of the powder inside the foam is obtained by the double action of stretching and pressure exerted by the sets of rollers 18 and 19. Of course these mechanical actions
are limited by the mechanical strength of the foam
chosen.
Après enduction de la couche de mousse 15 par la
colle 16, le complexe constitué par les couches 11 à 15
est introduit dans une presse dont seuls deux éléments ont
été représentés à savoir un plateau chauffant 23 et un
moule 24, le moule 24 étant bien entendu conformé selon
le dessin que l'on cherche à reproduire.After coating the foam layer 15 with the
glue 16, the complex consisting of layers 11 to 15
is introduced into a press of which only two elements have
been represented, namely a heating plate 23 and a
mold 24, the mold 24 being of course shaped according to
the drawing that we are trying to reproduce.
Au cours d'expérience réalisée, il s'est avéré
que les paramètres physiques de la thermocompression n'étaient
pas très critiques et des résultats très satisfaisants ont
été obtenus avec une température d'un plateau chauffant comprise entre 180 et 2200, le plateau étant appliqué sur le
complexe pendant un temps de 70 secondes environ avec une
pression de 2 bars.During the experiment carried out, it turned out
that the physical parameters of the thermocompression were
not very critical and very satisfactory results have
obtained with a temperature of a heating plate between 180 and 2200, the plate being applied to the
complex for about 70 seconds with a
pressure of 2 bars.
Il va de soi que des modifications peuvent etre
apportées au mode de réalisation qui vient d'être décrit
notamment par substitution de moyens techniques équivalents,
sans sortir pour celà du cadre de la présente invention. It goes without saying that modifications can be
brought to the embodiment which has just been described
in particular by substitution of equivalent technical means,
without departing from the scope of the present invention.
