Abstract
Description
La présente invention concerne une matelassure comportant un corps en mousse revêtu d'une coiffe perméable en matière textile naturelle ou synthétique dont il est solidaire. The present invention relates to a padding comprising a foam body coated with a permeable cap of natural or synthetic textile material to which it is integral.
il convient de préciser tout d'abord que le mot "matelassure" désigne ici un élément de rembourrage quelconque. I1 peut donc aussi bien désigner un pouf ou un coussin qutune partie de siège à usage domestique ou de siège de véhicule, par exemple une assise, un dossier ou un appuie-tete. it should be noted first of all that the word "padding" here means any padding element. I1 can therefore designate a pouf or a cushion as well as a part of a seat for household use or of a vehicle seat, for example a seat, a backrest or a headrest.
Les matelassures réalisées actuellement avec une coiffe perméable en matière textile qui est solidaire de leur corps ne donnent pas entière satisfraction. C'est par exemple le cas des matelassures obtenues par la mise en oeuvre des procédés de moulage préconisant l'application du vide. Ces procédés exigent en effet que la face interne des eoiffes soit revêtue d'une enduction imperméable, d'une part pour permettre l'utilisation du vide et d'autre part pour éviter que le melange réactionnel donnant naissance à la mousse, qui est coulé à l'état liquide, mouille la coiffe et forme sur celle-ci des taches ou des marques inesthétiques s'accompagnant de durcissements locaux inacceptables. The padding currently made with a permeable textile cap which is integral with their body does not give full satisfaction. This is for example the case of quilting obtained by the implementation of molding processes recommending the application of vacuum. These methods in fact require that the inner face of the hairstyles be coated with an impermeable coating, on the one hand to allow the use of the vacuum and on the other hand to prevent the reaction mixture giving rise to the foam, which is poured in the liquid state, wets the cap and forms unsightly marks or marks thereon accompanied by unacceptable local hardening.
Or, la présence de l'enduction imperméable a lvinconvénient d'empêcher le dégazage de la mousse en cours de formation et de s'opposer à ce que la matelassure puisse "respirer",. ce qui nuit considérablement au confort thermique et hygroscopique de l'usager.However, the presence of the waterproof coating has the disadvantage of preventing the degassing of the foam during formation and of preventing the padding from "breathing". which considerably affects the thermal and hygroscopic comfort of the user.
Pour eviter cet inconvénient résultant de la présence de l'enduction imperméable, certains industriels ont proposé une solution consistant à utiliser un simple moule dépourvu de moyens pour appliquer le vide dans sa cavité, et à couler directement sur la coiffe perméable disposée dans la cavité du moule, un mélange réactionnel se trouvant dans un état de réaction intermédiaire entre son état liquide et son étant d'expansion finale. Les matelassures réali- sees de cette façon offrent effectivement un certain confort thermique et hygroscopique.Cependant, comme il est difficile de déterminer le moment exact où il convient de réaliser la coulée du mélange réactionnel, il arrive fréquemment que celle-ci soit réalisée trop tdt et que le mélange réactionnel mouille la coiffe, ce qui est dommageable pour l'esthétique de la matelassure, ou au contraire qu'elle soit réalisée trop tard et que la mousse ne soit plus apte à adhérer à la coiffe, ce qui se traduit alors par une matelassure de mauvaise qualité. To avoid this drawback resulting from the presence of the waterproof coating, some manufacturers have proposed a solution consisting in using a simple mold devoid of means for applying the vacuum in its cavity, and in pouring directly onto the permeable cap disposed in the cavity of the mold, a reaction mixture being in a state of intermediate reaction between its liquid state and its being of final expansion. Quiltings made in this way do offer some thermal and hygroscopic comfort. However, since it is difficult to determine the exact moment when the reaction mixture should be poured, it often happens that it is carried out too soon. and that the reaction mixture wets the cap, which is harmful to the aesthetics of the padding, or on the contrary that it is carried out too late and that the foam is no longer able to adhere to the cap, which then results by poor quality padding.
La présente invention se propose donc de remédier à tous les inconvénients évoqués ci-dessus et, pour ce faire, elle a pour objet une matelassure en mousse revêtue d'une coiffe perméable solidaire de son corps, qui se carac térise en ce que la coiffe est doublée d'une feuille de mousse synthétique adhérant à sa face interne, et en ce que la mousse du corps résulte de l'expan sion d'un mélange réactionnel fortement catalysé, coulé directement sur la feuille alors qu'il est en cours de réaction mais encore fluide, cette mousse formant une couche superficielle dans ladite feuille sans atteindre la coiffe et sans provoquer de densification locale. The present invention therefore proposes to remedy all the drawbacks mentioned above and, to do this, it relates to a foam padding coated with a permeable cap integral with its body, which is characterized in that the cap is lined with a sheet of synthetic foam adhering to its internal face, and in that the body foam results from the expansion of a highly catalyzed reaction mixture, poured directly onto the sheet while it is being reaction but still fluid, this foam forming a surface layer in said sheet without reaching the cap and without causing local densification.
Grâce à la feuille de mousse, les risques pour que le mélange réactionnel mouille la coiffe sont totalement éliminés. Cette feuille constitue en effet une sorte de barrage s'opposant à la propagation de la mousse dans la coiffe, laquellc est protégée contre les taches et les durcissements locaux et garde donc son aspect noble d'origine. Thanks to the foam sheet, the risks of the reaction mixture wetting the cap are completely eliminated. This sheet in fact constitutes a sort of barrier opposing the propagation of the foam in the cap, which is protected against local stains and hardening and therefore retains its original noble appearance.
Par ailleurs, comme le mélange réactionnel utilisé est fortement catalysé, il peut être coulé pratiquement immédiatement après sa préparation puisque, son expansion commençant très rapidement, il présente un pouvoir mouillant réduit. Furthermore, as the reaction mixture used is highly catalyzed, it can be poured practically immediately after its preparation since, its expansion starting very quickly, it has a reduced wetting power.
Le fait de couler sans tarder le mélange réactionnel a en outre l'avantage de permettre une très bonne adhérence entre la mousse et la coiffe. The fact of immediately pouring the reaction mixture has the additional advantage of allowing very good adhesion between the foam and the cap.
En effet, lors de sa coulée, le mélange réactionnel forme une crème suffisamment fluide pour pénétrer superficiellement dans la feuille de mousse et assurer une solide liaison entre celle-ci et la mousse résultant de son expansion, et ce sans provoquer de densification nuisible au confort.In fact, during its pouring, the reaction mixture forms a cream which is sufficiently fluid to penetrate superficially into the foam sheet and to ensure a solid bond between it and the foam resulting from its expansion, without causing densification which is detrimental to comfort. .
Selon une première variante, la feuille de mousse synthétique est fixée à la coiffe par fusion superficielle. A titre indicatif, on notera que cette fusion superficielle peut par exemple être réalisée en faisant circuler la coiffe et la feuille de mousse de part et d'autre d'une rampe de chauffage au gaz et en les appliquant l'une contre l'autre à leur sortie de la rampe. According to a first variant, the synthetic foam sheet is fixed to the cap by surface fusion. As an indication, it will be noted that this surface fusion can for example be carried out by circulating the cap and the foam sheet on either side of a gas heating rail and applying them one against the other. as they exit the ramp.
Selon une autre variante, la feuille de mousse synthétique peut être fixée à la coiffe-par simple collage. According to another variant, the synthetic foam sheet can be fixed to the cover by simple bonding.
De préférence, la feuille adhérant à la coiffe a une épaisseur de l'ordre de 3 à 5 mm et est formée d'une mousse de polyuréthane, de polyéthylène ou de PVC. La mousse formée à partir du mélange réactionnel est quant à elle une mousse de polyuréthane. Preferably, the sheet adhering to the cap has a thickness of the order of 3 to 5 mm and is formed from a polyurethane, polyethylene or PVC foam. The foam formed from the reaction mixture is in turn a polyurethane foam.
Avantageusement, la mousse du corps de la matelassure résulte de l'expansion d'un mélange réactionnel contenant en parties en poids
- Polyol ..................... 100
- Eau ........................ 2,7 à 3,5
- Triéthylènediamine ......... o,8 à 1
- Organosilicone ............. 0,5 à 1
- Isocyanate ................. 35,5 à 43,3
La triéthylènediamine joue ici le rôle de catalyseur des gaz engendrés pendant la réaction. I1 est à noter que sa concentration est beaucoup plus élevée que dans les mélanges réactionnels habituels qui la contiennent et dans lesquels sa concentration est généralement comprise entre 0,1 et 0,15 partie en poids.Advantageously, the foam of the body of the padding results from the expansion of a reaction mixture containing in parts by weight
- Polyol ..................... 100
- Water ........................ 2.7 to 3.5
- Triethylenediamine ......... o, 8 to 1
- Organosilicone ............. 0.5 to 1
- Isocyanate ................. 35.5 to 43.3
Here, triethylenediamine acts as a catalyst for the gases generated during the reaction. It should be noted that its concentration is much higher than in the usual reaction mixtures which contain it and in which its concentration is generally between 0.1 and 0.15 parts by weight.
L'organosilicone, parfois désigné huile de silicone,-sert quant à lui de stabilisateur. Organosilicone, sometimes called silicone oil, is used as a stabilizer.
Si par ailleurs l'on souhaite augmenter la dureté de la mousse, on peut avantageusement introduire environ 0,5 partie en poids de diéthanolamine dans le mélange réactionnel, la diéthanolamine étant utilisée ici comme agent réticulant. If, moreover, it is desired to increase the hardness of the foam, it is advantageously possible to introduce about 0.5 part by weight of diethanolamine into the reaction mixture, diethanolamine being used here as crosslinking agent.
Un mode d'exécution de la présente invention sera décrit ci-après à titre d'exemple en référence au dessin annexé dans lequel la figure unique est une vue en coupe schématique partielle d'une matelassure conforme à l'invention. An embodiment of the present invention will be described below by way of example with reference to the accompanying drawing in which the single figure is a partial schematic sectional view of a padding according to the invention.
Comme on peut le voir sur le dessin, la matelassure comporte un corps en mousse 1 adherant d une feuille de mousse synthétique 2 fixée sur la face interne d'une coiffe en tissu 3. Les mousses constituant le corps 1 et la feuille 2 sont de préférence des mousses de polyuréthane. As can be seen in the drawing, the padding comprises a foam body 1 adhering to a sheet of synthetic foam 2 fixed to the internal face of a fabric cover 3. The foams constituting the body 1 and the sheet 2 are of preferably polyurethane foams.
Pour fabriquer cette matelassure, on procède de la manière suivante. To make this padding, we proceed as follows.
Tout d'abord, on fixe la feuille 2 sur la coiffe 3, par exemple en faisant circuler ces deux éléments de part et d'autre d'une rampe de chauffage au gaz et en les appliquant l'un contre l'autre lorsqu'il arrivent en aval de la rampe. On applique ensuite l'ensemble obtenu contre la surface interne de la cavité d'un moule, la feuille 2 étant tournée vers l'extérieur.First of all, the sheet 2 is fixed on the cover 3, for example by circulating these two elements on either side of a gas heating rail and applying them one against the other when they arrive downstream from the ramp. The assembly obtained is then applied against the internal surface of the cavity of a mold, the sheet 2 being turned outwards.
Lorsque cette opération est terminée, on déverse alors sur la feuille 2 un mélange réactionnel contenant par exemple les constituants ci-dessous dont les concentrations sont données en parties en poids
- Polyol .............................................. 100
(Commercialisé sous la dénomination Niax 32/32
et ayant un poids moléeulaire de 5.000)
- Eau .......................................... 3
- Triéthylènediamine ...................................... 0,9
(Commercialisée sous la dénomination Dabco)
- Huile de silicone ....................................... 0,7
(Commercialisée sous la dénomination Y6932)
- Diéthanolamine ........................................ 0,5
- Isocyanate ........................................ 40
(Commercialisé sous la dénomination 44VT et
résultant d'un mélange de diisocyanate de toluène avec
du diisocyanate de méthyldiphényle dans le rapport 60/40)
entant donné que ce mélange est fortement catalysé, il se transforme rapidement en une crème muuillantpeu la feuille 2Jqui ne pénètre que superficiellement dans celle-ci et qui de ce fait ne provoque pas de densification nuisible au confort.When this operation is complete, a reaction mixture is then poured onto sheet 2, containing for example the constituents below, the concentrations of which are given in parts by weight
- Polyol .............................................. 100
(Marketed under the name Niax 32/32
and having a molecular weight of 5,000)
- Water .......................................... 3
- Triethylenediamine ...................................... 0.9
(Marketed under the name Dabco)
- Silicone oil ....................................... 0.7
(Marketed under the name Y6932)
- Diethanolamine ........................................ 0.5
- Isocyanate ........................................ 40
(Marketed under the name 44VT and
resulting from a mixture of toluene diisocyanate with
methyldiphenyl diisocyanate in the 60/40 ratio)
given that this mixture is highly catalyzed, it rapidly transforms into a wetting cream for the sheet 2J which only penetrates superficially therein and which therefore does not cause densification which is detrimental to comfort.
Puis l'on ferme le moule pour permettre l'expansion du mélange réactionnel. Lorsque le moule est fermé, la mousse en cours de formation créé une pression interne intense qui contraint toutes les parties du tissu 1 à venir intimement contre la surface interne de la cavité de moulage et donc à se conformer fidèlement aux formes et dessins de cette surface. Par ailleurs, comme la feuille 2 et la coiffe 3 sônt perméables, les gaz de réaction peuvent aisément les traverser et par conséquent s'échapper de la mousse en cours de formation, ce qui évite la formation de bulles qui risqueraient de nuire à leur tour au confort. Then the mold is closed to allow the expansion of the reaction mixture. When the mold is closed, the foam being formed creates an intense internal pressure which forces all the parts of the fabric 1 to come intimately against the internal surface of the mold cavity and therefore to conform faithfully to the shapes and drawings of this surface. . Furthermore, as the sheet 2 and the cap 3 are permeable, the reaction gases can easily pass through them and consequently escape from the foam during formation, which avoids the formation of bubbles which could in turn harm comfort.
On procède enfin au démoulage lorsque la mousse a cessé de s'expanser. Finally, the mold is removed from the mold when the foam has ceased to expand.
A ce moment la, la couche superficielle que celle-ci a formée dans la feuille est en effet devenue suffisamment dure pour assurer une bonne liaison entre elle et cette feuille. At this time, the surface layer that the latter has formed in the sheet has indeed become sufficiently hard to ensure a good bond between it and this sheet.
