Description

La présente invention a pour objet une feuille-­transfert pour procédé de finissage de cuir.The present invention relates to a transfer sheet for a leather finishing process.

On connaît déjà, par exemple par FR-A-2 597 505 au nom de la Demanderesse, un procédé d'obtention de pièces en cuir prêtes à l'usage pour la confection de chaussures, articles de maroquinerie ou autres suivant lequel on effec­tue le finissage de pièces en cuir brut par un processus de transfert conduit dans une machine de moulage/pressage à haute fréquence. Pour la mise en oeuvre de ce procédé un support indépendant du cuir brut, par exemple du papier si­liconé, est garni de couches successives du ou de pro­duit(s) d'apprêt puis du ou de produit(s) de finissage choisis parmi les matières synthétiques ou naturelles propres à être réactivées à chaud et présentant des pertes diélectriques pour former une feuille-transfert.We already know, for example from FR-A-2,597,505 in the name of the Applicant, a process for obtaining ready-to-use leather parts for the manufacture of shoes, leather goods or the like, according to which the finishing of rawhide parts by a transfer process carried out in a high frequency molding / pressing machine. For the implementation of this process, a support independent of the rawhide, for example silicone paper, is lined with successive layers of the finish product (s) and then the finish product (s) chosen from the materials synthetic or natural suitable for being reactivated hot and having dielectric losses to form a transfer sheet.

Les travaux de la Demanderesse poursuivis depuis la mise au point du procédé rappelé ci-dessus ont maintenant montré que, parmi les très nombreux produits susceptibles d'être mis en oeuvre, certains se révélaient particulièrement avantageux, tant par leurs caractéris­tiques propres que par la combinaison de leurs propriétés pour l'obtention d'une feuille-transfert satisfaisante et, étant donné que, les impératifs de coût, de facilité d'exploitation, et d'obtention d'un produit d'aspect et de qualité satisfaisants sont de première importance pour le procédé selon le brevet français mentionné ci-dessus, c'est, d'une façon générale, un but de l'invention de four­nir une telle feuille-transfert perfectionnée.The work of the Applicant continued since the development of the process recalled above has now shown that, among the very many products capable of being used, some were found to be particularly advantageous, both by their own characteristics and by the combination of their properties for obtaining a satisfactory transfer sheet and, given that the requirements of cost, ease of operation, and obtaining a product of satisfactory appearance and quality are of primary importance for the method according to the French patent mentioned above, it is generally an object of the invention to provide such an improved transfer sheet.

C'est, aussi, un but de l'invention de fournir une telle feuille-transfert qui non seulement conduise à de bons résultats lors de sa mise en oeuvre mais qui, en outre, soit d'une conception telle qu'elle peut être fabri­quée à l'aide de machines automatiques, en continu, ce qui non seulement en réduit le coût mais également conduit à un produit de caractéristiques constantes et stables.It is also an object of the invention to provide such a transfer sheet which not only leads to good results during its implementation but which, moreover, is of a design such that it can be manufactured using automatic machines, continuously, which not only reduces the cost but also leads to a product with constant and stable characteristics.

C'est, encore, un but de l'invention de fournir une telle feuille-transfert qui permette d'atteindre les résultats recherchés de façon simple et sûre.It is, again, an object of the invention to provide such a transfer sheet which makes it possible to achieve the desired results in a simple and safe manner.

Une feuille-transfert selon l'invention, pour le finissage de cuir sous forme de peau ou sous forme d'une pièce prête à l'usage pour la confection des chaussures, d'articles de maroquinerie ou analogues, comportant un support garni de couches superposées de produits d'apprêt et/ou de finissage, ainsi que d'une couche adhésive dis­tincte ou incorporée à l'un des produits d'apprêt et/ou de finissage propres à être réactivés à chaud et présentant des pertes diélectiques est caractérisée en ce que le maté­riau de la couche au contact du support et destinée à for­mer le finissage de surface est choisi parmi les produits du type nitrocellulose plastifiée ou polyuréthanne monocom­posant en solution dans des solvants appropriés pour son accrochage sur ledit support, en ce que ladite première couche est revêtue d'une seconde couche assurant la soli­dité du finissage et le coloris dont le matériau est choisi parmi des dispersions aqueuses de polyuréthanne alipha­tique, et de colopymères acryliques ou les polyuréthannes monocomposants de type aromatique en solution organique et en ce qu'à ladite seconde couche est incorporé un adhésif thermoplastique du type copolymère de polyuréthanne/acétate de vinyle, propre à être réactivé aux environ de 100 °C et qui, en variante, est disposé sur ladite seconde couche sous forme d'une troisième couche distincte.A transfer sheet according to the invention, for finishing leather in the form of skin or in the form of a ready-to-use piece for making shoes, leather goods or the like, comprising a support provided with layers superimposed of priming and / or finishing products, as well as a separate adhesive layer or incorporated into one of the priming and / or finishing products suitable for being reactivated when hot and having dielectric losses is characterized in that the material of the layer in contact with the support and intended to form the surface finishing is chosen from products of the plasticized nitrocellulose or single-component polyurethane type dissolved in solvents suitable for its attachment to said support, in that said first layer is coated with a second layer ensuring the solidity of the finish and the color, the material of which is chosen from aqueous dispersions of aliphatic polyurethane and acrylic colopymers es or one-component polyurethanes of aromatic type in organic solution and in that in said second layer is incorporated a thermoplastic adhesive of the polyurethane / vinyl acetate copolymer type, suitable for being reactivated at approximately 100 ° C. and which, as a variant , is arranged on said second layer in the form of a separate third layer.

Dans une forme de réalisation préférée le support est, de façon en soi connue , du papier siliconé et le matériau constitutif de la première couche au contact dudit papier est en solution dans un mélange de solvants du type méthyléthylcétone et cyclohexane pour permettre une bonne adhésion dudit matériau sur le papier nonobstant les mauvaises caractéristiques d'accrochage sur un tel papier. Dans cette forme de réalisation, également, la deuxième couche est en solution soit dans un mélange de solvants du type méthyléthylécétone et diméthylformamide pour les poly­uréthannes organiques, soit dans l'eau pour les dispersions aqueuses ; la couche adhésive étant, quant à elle, consti­tuée par un adhésif thermoplastique en solution organique.In a preferred embodiment, the support is, per se known, silicone paper and the material constituting the first layer in contact with said paper is in solution in a mixture of solvents of the methyl ethyl ketone and cyclohexane type to allow good adhesion of said material on the paper notwithstanding the bad bonding characteristics on such a paper. In this embodiment, also, the second layer is in solution, either in a mixture of solvents of methylethylecetone and dimethylformamide type for organic polyurethanes, or in water for aqueous dispersions; the adhesive layer being, for its part, constituted by a thermoplastic adhesive in organic solution.

La première couche, au contact du papier sili­coné, et qui est destinée à fournir le finissage de la peau ou de la pièce de cuir peut être teintée ou transparente.The first layer, in contact with the silicone paper, and which is intended to provide the finishing of the skin or the piece of leather can be tinted or transparent.

Dans le premier cas, les teintures mises en oeuvres sont celles utilisées dans l'industrie du cuir, par exemple des pigments peu couvrants organiques et minéraux, dans un liant nitrocellulosique modifié.In the first case, the dyes used are those used in the leather industry, for example little organic and mineral pigments, in a modified nitrocellulosic binder.

Dans le deuxième cas, c'est-à-dire avec une première couche transparente, la couleur ou les couleurs est (sont) donnée(s) par la deuxième couche qui est alors avantageusement une dispersion aqueuse afin d'éviter tout phénomène de réaction avec le matériau constitutif de la première couche.In the second case, that is to say with a first transparent layer, the color or colors is (are) given (s) by the second layer which is then advantageously an aqueous dispersion in order to avoid any reaction phenomenon with the material of the first layer.

Une telle disposition est particulièrement pré­férée lorsque l'on souhaite donner à la peau ou à la pièce de cuir une coloration en deux tons ou deux couleurs, par exemple pour la réalisation de motifs donnant à la peau ou à la pièces de cuir l'aspect d'écailles de serpent, ou analogue.Such an arrangement is particularly preferred when it is desired to give the skin or the piece of leather a coloration in two tones or two colors, for example for producing patterns giving the skin or the pieces of leather the appearance snake scales, or the like.

Compte tenu de la nature des constituants de la feuille-transfert, celle-ci peut être aisément fabriquée sur une machine automatique par un processus continu sui­vant lequel lesdits constituants sont disposés en couches successives sur le support de base.Given the nature of the constituents of the transfer sheet, it can be easily manufactured on an automatic machine by a continuous process according to which said constituents are arranged in successive layers on the base support.

Dans une variante de réalisation, l'adhésif destiné à la fixation de l'ensemble des couches d'apprêt et/ou de finissage sur les croûtes ou fleurs de cuir non finies est incorporé à la seconde couche de la feuille-­transfert, c'est-à-dire celle destinée à donner la solidité du finissage.In an alternative embodiment, the adhesive intended for fixing all the primer and / or finishing layers on the crusts or unfinished leather flowers is incorporated into the second layer of the transfer sheet, ie that is to say that intended to give the solidity of the finishing.

Quel que soit le nombre de couches de la feulle-transfert, le procédé de fabrication tel que défini ci-dessus fournit une épaisseur de film constante, uni­forme, permettant de conserver au cuir sa souplesse natu­relle et procurant en outre une économie importante des produits d'apprêt et/ou de finissage.Regardless of the number of layers of the transfer sheet, the manufacturing process as defined above provides a constant, uniform film thickness, allowing the leather to retain its natural suppleness and also providing a significant saving in finishing and / or finishing products.

Pour la mise en oeuvre de la feuille-transfert ainsi fabriquée cette dernière est d'abord pre-collée sur le cuir par un processus d'application thermique effectué soit à l'aide d'une presse chauffante, soit d'une presse rotative de serrage en continu et cela pour séparer facile­ment le papier siliconé de la couche de finissage , ce pré-­collage étant effectué soit sur des peaux entières, soit sur des morceaux pré-découpés en fonction des pièces en cuir que l'on souhaite utiliser pour la fabrication de chaussures, d'articles de maroquinerie, ou analogues. la peau ou pièce en cuir est alors soumise à une opération finale dans une machine à haute fréquence, comme décrit dans le brevet français pré-cité pour l'obtention d'un grain particulier sur ladite peau ou pièces ou partie de pièce.For the implementation of the transfer sheet thus produced, the latter is first pre-bonded to the leather by a thermal application process carried out either using a heating press or a rotary press. continuous tightening and this to easily separate the silicone paper from the finishing layer, this pre-bonding being carried out either on whole skins, or on pre-cut pieces according to the leather pieces that one wishes to use for the manufacture of shoes, leather goods, or the like. the skin or piece of leather is then subjected to a final operation in a high-frequency machine, as described in the aforementioned French patent for obtaining a particular grain on said skin or pieces or part of a piece.
