Description
L'invention concerne un procédé de fabrication de feutres végétaux à partir d'étoupes ainsi que le produit obtenu par ce procédé et notamment son utilisation dans l'isolation thermique et/ou phonique ou encore dans le domaine de l'emballage.The invention relates to a method of manufacturing felt pens plants from tows and the product obtained by this process and especially its use in thermal and / or sound insulation or in the field of packaging.
L'utilisation des fibres naturelles, notamment végétales, dans de nombreuses applications remonte aux origines de l'homme. Ces fibres étaient jusqu'au début du XXème siècle les seules fibres utilisées pour la réalisation de vêtements, de cordages, et dans de nombreuses autres réalisations artisanales ou dans l'industrie naissante, telles que l'industrie automobile, le transport aérien, ferroviaire, etc.The use of natural fibers, including plants, in many applications goes back to the origins of man. These fibers were until the early twentieth century the only fiber used to make clothing, rope, and many other craft projects or infant industry such as the automotive, aviation, railway etc.
A la fin du XIX et début du XXème siècle, les sièges et les réservoirs à carburant des premiers avions étaient en fibres naturelles imprégnées d'un peu de polymère, qui jouait le rôle de liant.At the late nineteenth and early twentieth century, the seats and the fuel tanks of the first aircraft were natural fibers impregnated with some polymer, which acted as the binder.
A partir des années 1950, les fibres synthétiques s'imposèrent grâce notamment au bas prix du pétrole et au développement de la pétrochimie. Les fibres d'origine naturelle ne retiennent à nouveau l'attention que depuis les années 1990.From the 1950s, synthetic fibers became essential thanks in particular to the low price of oil and the development of petrochemicals. Natural fibers do not catch the attention again than since the 1990s.
L'utilisation des fibres d'origine naturelle, notamment végétale, au lieu des fibres de verre, permet de réaliser des composites dont la masse volumique est notablement inférieure à celle obtenue avec des fibres de verre pour les mêmes caractéristiques mécaniques.The use of fibers of natural origin, in particular vegetable, instead of glass fibers, it is possible to produce composites whose mass volume is significantly lower than that obtained with glass fibers for the same mechanical characteristics.
Par ailleurs, la cellulose étant le polymère le plus répandu de la biosphère, l'utilisation de cette ressource de matière primaire, renouvelable par culture, permet d'économiser des réserves naturelles utilisées pour la production de certaines fibres synthétiques, comme par exemple le pétrole.Moreover, cellulose being the most widespread polymer of the biosphere, the use of this resource of primary material, renewable by crop, saves natural reserves used for the production of certain synthetic fibers, such as oil.
En outre, l'utilisation des fibres d'origine végétale peut être envisagée dans de nombreux domaines industriels, notamment automobiles.In addition, the use of plant-based fibers may be envisaged in many industrial fields, particularly automobiles.
Toutefois, bien que très répandus, les matériaux obtenus à partir des fibres naturelles présentent de nombreux inconvénients, notamment en ce qui concerne leur composition chimique et leur procédé de fabrication.However, although widespread, the materials obtained from natural fibers have many disadvantages, in particular as regards their chemical composition and manufacturing process.
Actuellement, les matériaux obtenus à partir des fibres naturelles, sont fabriqués soit par aiguillage à partir de fibres courtes faiblement chargées en anas, soit en imprégnant les fibres naturelles d'une matrice thermodurcissable, telle qu'une résine époxy, vinylester ou polyester.Currently, materials obtained from fibers natural products, are made either by switching from short fibers weakly charged in shives, either by impregnating the natural fibers with thermosetting matrix, such as an epoxy, vinylester or polyester resin.
Le but de la présente invention est de proposer un procédé de fabrication de feutres végétaux qui pallie les inconvénients précités, notamment en ce qui concerne le procédé de fabrication.The object of the present invention is to propose a method of manufacture of vegetable felts which overcomes the aforementioned drawbacks, particularly with regard to the manufacturing process.
Un autre but de la présente invention est de proposer la fabrication de feutres 100 % végétaux.Another object of the present invention is to propose the manufacture of 100% vegetable felts.
D'autres buts et avantages de la présente invention apparaítront au cours de la description qui va suivre qui n'est donnée qu'à titre indicatif et qui n'a pas pour but de la limiter.Other objects and advantages of the present invention will appear in the following description which is given only as a indicative and which is not intended to limit it.
La présente invention concerne un procédé pour la fabrication de feutres végétaux à partir d'étoupes obtenues après séparation de la partie ligneuse de la fibre, caractérisé par le fait que :
- on broie les étoupes pour former un broyat fibreux,
- on brasse le broyat fibreux en milieu liquide,
- on soumet le broyat fibreux brassé à un traitement thermique,
- on moule le broyat fibreux brassé pour former un feutre,
- on sèche le feutre obtenu.
- the tows are ground to form a fibrous ground material,
- the fibrous ground material is stirred in a liquid medium,
- the stirred fibrous ground material is subjected to a heat treatment,
- the stirred fibrous ground material is molded to form a felt,
- the felt obtained is dried.
La présente invention sera mieux comprise à la lecture de la description suivante.The present invention will be better understood on reading the following description.
Les étoupes utilisées dans la présente invention sont obtenues en utilisant des méthodes classiques de séparation de la partie ligneuse de la fibre dans les plantes textiles.The tows used in the present invention are obtained using conventional methods of separating the woody part of the fiber in textile plants.
Les fibres utilisées selon la présente invention sont fortement chargées en anas, ce qui permet de valoriser de nombreux coproduits végétaux plus ou moins ligneux et de respecter les impératifs environnementaux de recyclage.The fibers used according to the present invention are strongly loaded in anas, which allows to value many co-products more or less woody plants and to respect the imperatives environmental recycling.
Ainsi, la présence de poussières pectiques n'est pas un handicap et les étoupes peuvent être utilisées sans nettoyage à la sortie du teillage. Par « teillage », on entend l'opération mécanique qui consiste à séparer les fibres textiles du reste de la tige du végétal.Thus, the presence of pectic dust is not a disability and tows can be used without cleaning at the exit of the stripping. "Scutching" means the mechanical operation that consists of separate the textile fibers from the rest of the plant stem.
Par ailleurs, selon la présente invention, les feutres obtenus sont 100 % végétaux.Furthermore, according to the present invention, the felt obtained are 100% vegetable.
En outre, les fibres utilisées lors du procédé peuvent être blanchies préalablement par traitement chimique sans incidence sur le procédé.In addition, the fibers used in the process can be previously bleached by chemical treatment without affecting the process.
Selon l'invention, dans une première étape, on broie les étoupes pour former un broyat fibreux. Plus précisément, dans cette étape, on broie les étoupes afin de les transformer en flocons cotonneux.According to the invention, in a first step, the tows to form a fibrous ground material. More precisely, in this step, we grind the tows into fluffy flakes.
Cela étant, d'autres coproduits agricoles cellulosiques et/ou lignocellulosiques peuvent éventuellement être incorporés en mélange, et ainsi on broie les étoupes pour former un broyat fibreux éventuellement avec d'autres coproduits cellulosiques et/ou lignocellulosiques.However, other cellulosic agricultural co-products and / or lignocellulosic can optionally be incorporated as a mixture, and thus the tows are ground to form a fibrous grind, possibly with other cellulosic and / or lignocellulosic co-products.
Plus précisément, les étoupes, de lin par exemple, peuvent être substituées en partie, dans des proportions variables pouvant atteindre 95 %, suivant les caractéristiques physico chimiques, hydriques, mécaniques et thermiques souhaitées, par d'autres étoupes, ou plus généralement, par tout autre substance végétale cellulosique et/ou lignocellulosique, voire en mélange, dont notamment les pulpes de betteraves.More specifically, tows, eg linen, can to be partially substituted, in varying proportions that can reach 95%, depending on the physicochemical, hydric and mechanical characteristics and desired thermal, by other tows, or more generally, by any other cellulosic and / or lignocellulosic plant mixture, including beet pulp.
Le type de broyage peut être adapté aux matériaux de départ et à la texture souhaitée, produisant des feutres qui peuvent être plus ou moins fins suivant la proportion de fractions ligneuses et le type de broyage.The type of grinding can be adapted to the starting materials and the desired texture, producing felts that can be more or less ends according to the proportion of ligneous fractions and the type of grinding.
Selon un mode particulier de la présente invention, les étoupes sont des étoupes de lin.According to a particular embodiment of the present invention, the tows are tows of flax.
Le lin a l'avantage de présenter de bonnes propriétés
mécaniques parmi d'autres fibres végétales (tableau ci-dessous) et d'être
d'approvisionnement facile en France.
En outre, les étoupes de lin peuvent être utilisées, qu'elles soient issues de lin oléagineux ou de lin fibre, quelles que soient les variétés et quels que soient les traitements subis en culture et le degré de rouissage. Par « rouissage », on entend l'action microbienne ayant pour but d'éliminer le ciment pectique enrobant les fibres cellulosiques de l'écorce des plantes textiles, telles que le lin, et d'isoler ces dernières en vue d'obtenir la filasse.In addition, flax tow can be used, whether oleaginous linseed or flax fiber, whatever the varieties and regardless of the treatments undergone in culture and the degree of retting. By "Retting" means the microbial action intended to eliminate the pectic cement encapsulating cellulosic fibers in the bark of plants textiles, such as flax, and to isolate the latter in order to obtain the tow.
Selon la présente invention, et après la première étape de broyage des étoupes afin d'obtenir un broyat fibreux, dans une deuxième étape on brasse les broyats en milieu liquide.According to the present invention, and after the first step of grinding tows to obtain a fibrous grind, in a second step the bromates are brewed in a liquid medium.
Selon un mode particulier de la présente invention, le brassage est réalisé à froid en milieu aqueux, et peut être réalisé manuellement ou mécaniquement. Le brassage reste très court, de l'ordre de la minute et l'eau est apportée en quantité suffisante pour imbiber totalement la fibre, éliminant de cette façon une partie des molécules hydrosolubles.According to a particular embodiment of the present invention, brewing is carried out cold in an aqueous medium, and can be carried out manually or mechanically. The brewing remains very short, of the order of the minute and the water is provided in sufficient quantity to totally soak the fiber, eliminating in this way a part of the water-soluble molecules.
Selon la présente invention et après la deuxième étape, on soumet le broyat fibreux brassé à un traitement thermique. Plus particulièrement, le traitement thermique auquel le broyat fibreux est soumis est effectué par micro-ondes. Le temps de traitement est adapté à la puissance de l'appareil micro-ondes et à son mode de fonctionnement, à savoir en continu ou discontinu.According to the present invention and after the second step, subject the stirred fibrous ground material to heat treatment. More in particular, the heat treatment to which the fibrous ground material is subjected is carried out by microwaves. The treatment time is adapted to the power of the microwave and its mode of operation, know continuously or discontinuously.
A titre d'exemple, non limitatif, on a obtenu de bons résultats avec une fréquence de 2.450 MHz et une puissance de 900 W, et avec un temps de traitement en discontinu de l'ordre de 1 mn pour 10 g de broyat sec.By way of non-limiting example, good results have been obtained with a frequency of 2.450 MHz and a power of 900 W, and with a batch treatment time of the order of 1 min for 10 g of dry ground matter.
L'échauffement par micro-ondes en milieu humide présente l'avantage de la rapidité, de l'absence d'inertie, car les arrêts et les mises en route sont instantanés, de la facilité d'utilisation avec une régulation de la puissance aisée.Microwave heating in a humid environment the advantage of speed, of lack of inertia, because the stops and the road are instantaneous, ease of use with a regulation of the easy power.
En outre, le transfert de l'énergie est rapide dans toute la masse de broyat sans surchauffe superficielle.In addition, the transfer of energy is fast throughout the ground mass without overheating.
Par ailleurs, l'agitation moléculaire au sein du mélange suffit pour enchevêtrer les fibres pendant qu'une fraction de l'eau s'élimine par évaporation, ce qui favorise le séchage postérieur du produit. Moreover, the molecular agitation within the mixture is sufficient to entangle the fibers while a fraction of the water is removed by evaporation, which favors the posterior drying of the product.
Selon une quatrième étape, on moule le broyat fibreux brassé pour former un feutre . Plus précisément, après le traitement micro-ondes, le mélange fibreux humide est coulé à chaud dans un moule et notamment pressé pour éliminer la plus grande partie de l'eau. Avec le pressage, l'échantillon de fibres est ramené à environ la moitié de son volume initial et un compactage plus ou moins important peut être appliqué suivant la texture souhaitée.In a fourth step, the stirred fibrous ground material is molded to form a felt. More precisely, after the microwave treatment, the wet fibrous mixture is cast in a hot mold and in particular pressed to remove most of the water. With the pressing, the fiber sample is reduced to about half of its original volume and a more or less compactness can be applied according to the texture desired.
Selon une cinquième étape, on sèche le feutre obtenu. Plus précisément, et selon un exemple, le séchage des fibres peut être réalisé en deux étapes, une première étape de séchage avec les fibres dans le moule, et une deuxième étape avec les fibres démoulées. Dans d'autres modes de réalisation, le séchage pourra être effectué par hyperfréquence ou par infrarouge ou tout traitement adapté.According to a fifth step, the felt obtained is dried. More precisely, and according to one example, the drying of the fibers can be carried out in two steps, a first drying step with the fibers in the mold, and a second step with the demolded fibers. In other modes of realization, the drying can be carried out by microwave or by infrared or any suitable treatment.
On a obtenu de bons résultats en réalisant le séchage dans une enceinte ventilée, à une température de l'ordre de 70 °, pendant 24 heures et avec les fibres dans le moule. Les fibres ont été ensuite démoulées et le séchage se poursuit jusqu'à masse constante. Le temps de séchage peut s'adapter en fonction de la taille de l'échantillon de fibres.Good results have been obtained by carrying out the drying in a ventilated enclosure, at a temperature of about 70 °, for 24 hours and with the fibers in the mold. The fibers were then removed from the mold and the drying continues until constant mass. The drying time can adapt according to the size of the fiber sample.
Un autre but de la présente invention concerne le produit obtenu par le procédé objet de ce brevet.Another object of the present invention relates to the product obtained by the process object of this patent.
Ce produit, à savoir un feutre 100 % végétal, présente l'avantage d'être compatible avec des matériaux minéraux, de pouvoir être façonné à volonté lors du procédé et de conserver sa forme après séchage.This product, namely a 100% vegetable felt, presents the advantage of being compatible with mineral materials, of being able to shaped at will during the process and retain its shape after drying.
En outre, les feutres sont totalement recyclables en circuit fermé pour la production de nouveaux feutres ou pour la production de compost, dans le cas de feutres en fin de vie.In addition, the felts are completely recyclable in circuit closed for the production of new felts or for the production of compost, in the case of end-of-life markers.
Par ailleurs, les feutres obtenus par le présent procédé peuvent être rendus ininflammables.Moreover, the felts obtained by the present process can be made non-flammable.
Selon la présente invention, le produit obtenu selon le procédé décrit dans la présente invention est utilisé dans l'isolation thermique et/ou phonique, ainsi que dans divers accessoires d'ameublement, dans l'industrie automobile, industries du jouet et de la décoration, de l'emballage, de l'horticulture, etc.According to the present invention, the product obtained according to the process described in the present invention is used in thermal insulation and / or soundproofing, as well as in various furnishing accessories, in the automotive industry, toy and decoration industries, packaging, horticulture, etc.
Naturellement, d'autres modes de réalisation de la présente invention, à la portée de l'homme de l'art, auraient pu être envisagés sans pour autant sortir du cadre de l'invention.Of course, other embodiments of this invention, within the reach of those skilled in the art, could have been envisaged without as far out of the scope of the invention.
