Abstract
Description
La présente invention concerne des matériaux composites stratifiés constitués dessus d'une mince couche de croûte de cuir obtenue par sciage de croûtes d'épaisseur traditionnelle ayant été préalablement finies et / ou teintes sur leurs deux faces liées à un ou plusieurs produits en renfort dessous. The present invention relates to laminated composite materials formed above a thin layer of crust of leather obtained by sawing crusts of traditional thickness having been previously finished and / or dyed on their two faces linked to one or more reinforcing products below.
L'invention concerne également les procédés d'obtention de ces matériaux ainsi que les articles manufacturés composés avec ceux-ci. The invention also relates to the processes for obtaining these materials as well as to the manufactured articles composed with them.
Les progrès constants des tanneries en matière de travail et de finitions des croûtes de cuir traditionnelles augmentent en amont et en aval de ces tanneries l'intérêt économique de ces croûtes, leurs applications mais également leurs prix en raison de leurs limites d'offres sur le marché du cuir. The constant progress of tanneries in terms of work and finishing of traditional leather crusts increases upstream and downstream of these tanneries the economic interest of these crusts, their applications but also their prices because of their supply limits on the market. leather market.
Le travail en tanneries de ces croûtes exige une prise en compte des résistances aux diverses contraintes que peuvent subir ces croûtes pendant leur processus de fabrication ainsi leurs épaisseurs sont toujours égales ou supérieures à l'épaisseur à laquelle leur résistance ne le supporterait pas. The work in tanneries of these crusts requires taking into account the resistances to the various constraints that these crusts can undergo during their manufacturing process so their thicknesses are always equal to or greater than the thickness at which their resistance would not support it.
Les croûtes traditionnelles destinées aux diverses applications en terme d'articles manufacturés comportent toujours des finitions recherchées pour constituer la face apparente de ces articles uniquement sur l'une des faces de ces croûtes. Traditional crusts intended for various applications in terms of manufactured articles always include finishes sought to constitute the visible face of these articles only on one of the faces of these crusts.
Les pratiques de sciage utilisées dans les tannenes engendrent fréquemment des sous produits sous forme de croûtes d'épaisseur et de résistance insuffisantes pour leur faire subir certaines opérations de travail en tanneries.Ces minces couches de croûtes de cuir proviennent de phases antérieures à la teinture des croûtes ou cuirs dont ils sont les sous produits. Les sciages sont opérés à ces stades pour uniformiser les épaisseurs des croûtes afin d'obtenir des teintures uniformes. The sawing practices used in tanning frequently generate by-products in the form of crusts of insufficient thickness and resistance to make them undergo certain working operations in tanneries. These thin layers of crust of leather come from phases prior to dyeing crusts or leathers of which they are the by-products. The sawn timber is operated at these stages to standardize the thickness of the crusts in order to obtain uniform dyes.
Les variétés de sous produits de sciage sous forme de minces couches de croûtes de cuir de part leurs inconvénients de résistance constituent des déchets lorsque le sciage dont ils proviennent est effectué en humide. Lorsque ce sciage est effectué à sec ces croûtes sans résistance suffisante constituent des produits dévalorisés qui servent principalement d'éléments internes de produits composites dont la surface est constituée de matériaux synthétiques imitant le cuir. Varieties of sawing by-products in the form of thin layers of split leather due to their resistance disadvantages constitute waste when the sawing from which they come is carried out in wet conditions. When this sawing is carried out dry, these crusts without sufficient resistance constitute devalued products which serve mainly as internal elements of composite products whose surface is made of synthetic materials imitating leather.
Les autres applications de ces couches consistent à les lier par collage à des renforts compatibles avec des utilisations comparables à celles des croûtes de cuir traditionnelles aussi bien dans leur travail en tannerie que dans leurs utilisations dans les diverses industries produisant des articles manufacturés. The other applications of these layers consist in bonding them by gluing to reinforcements compatible with uses comparable to those of traditional crusts of leather as well in their work in tanning as in their uses in the various industries producing manufactured articles.
Ces types de produits sont compris de l'état des techniques actuelles, mais ne trouvent dans la réalité que peu d'existence pour deux causes principales:
- leurs coûts élevés correspondant aux coûts de la mince couche de croûte de cuir plus son renfort ainsi que de l'application de ce renfort et des diverses opérations nécessaires à son travail en tanneries.These types of products are understood from the state of the art, but in reality find little existence for two main causes:
- their high costs corresponding to the costs of the thin layer of split leather plus its reinforcement as well as the application of this reinforcement and the various operations necessary for its work in tanneries.
- l'incompatibilité de ces produits composites avec un nombre important d'opérations en tanneries dans lesquelles les matériels sont conçus pour les traitements de cuirs ou de croûtes dont les propriétés physiques different largement de ces produits composites. - the incompatibility of these composite products with a large number of tanneries operations in which the materials are designed for the treatment of hides or crusts whose physical properties differ widely from these composite products.
Au contraire de tous ces produits et processus connus, la présente invention consiste en une division par sciage au moins par deux de croûtes d'épaisseur traditionnelle ayant été préparées, finies et / ou teintes sur leurs deux faces pour constituer à partir de ces deux faces ou plus les faces externes des produits composites pour lesquels elles sont destinées. Unlike all these known products and processes, the present invention consists in dividing by sawing at least by two crusts of traditional thickness having been prepared, finished and / or dyed on their two faces to form from these two faces. or more the external faces of the composite products for which they are intended.
La présente invention permet la création à coût avantageux de matériaux pouvant remplacer les croûtes de cuir traditionnelles. The present invention allows the creation, at an advantageous cost, of materials which can replace traditional leather crusts.
L'invention présente a pour avantage entre autres de permettre l'obtention d'articles composites de même nature de surface, indifféremment que cette surfàce provienne du dessus ou du dessous de la croûte préparée préalablement au sciage sur ses deux faces car les natures des surfaces externes des croûtes présentent des caractéristiques très proches. L'exploitation sous cette forme n'entraîne pas de contraintes économiques engendrées par une exploitation des deux faces avec deux différents aspects qui impliquent une commercialisation distincte. The present invention has the advantage, among other things, of making it possible to obtain composite articles of the same type of surface, regardless of whether this surface originates from above or from below the crust prepared before sawing on its two faces because the natures of the surfaces external crusts have very similar characteristics. Exploitation in this form does not entail economic constraints generated by an exploitation of the two sides with two different aspects which imply a separate marketing.
L'invention présente peut être utilisée dans toutes les industries du cuir et notamment les tanneries, mégisseries, industries de la chaussure, de la maroquinerie, de l'ameublement, de l'habillement, de la sellerie ainsi que dans toutes autres industries intéressées. The present invention can be used in all leather industries and in particular tanneries, tanning, footwear, leather goods, furniture, clothing, saddlery as well as in all other interested industries.
La présente invention s'applique à toutes croûtes provenant d'origine animale et notamment de bovins, équidés, ovins, caprins, reptiles et poissons. The present invention applies to all crusts originating from animal origin and in particular from cattle, equines, sheep, goats, reptiles and fish.
La présente invention comprend tous les types de finitions sans limitation et notamment en lisse, imprimé, velours, vernis, crispé, frippé, froissé, nappa, pigmenté, nubbuck, polyuréthanne, grainé. Toutes les finitions peuvent être appliquées avant ou après sciage. The present invention includes all types of finishes without limitation and in particular in smooth, printed, velvet, varnish, crisp, frizzy, crumpled, nappa, pigmented, nubbuck, polyurethane, grained. All finishes can be applied before or after sawing.
Le renfort des produits composites issu de la présente invention peut être constitué d'une ou plusieurs couches de produits. La liaison de ou des supports à la mince couche de croûte de cuir constituant le dessus peut être effectuée par collage et / ou couture. Cette liaison peut comprendre l'ensemble des surfaces ou bien une partie afin d'obtention d'effet de relieS matelas sage, gauffrage, etc.. The reinforcement of the composite products resulting from the present invention can consist of one or more layers of products. The bonding of the support (s) to the thin layer of crust of leather constituting the top can be carried out by gluing and / or sewing. This connection may include all of the surfaces or else a part in order to obtain the effect of connecting mattresses, embossing, etc.
L'invention ne se limite pas aux seuls modes de mise en oeuvre décrits ci-dessus. Ces modes sont donnés à titre d'exemples non limitatifs. The invention is not limited to only the modes of implementation described above. These modes are given by way of nonlimiting examples.
