Description
La présente invention porte sur un fil à base de mica, c'est-à-dire un fil constitué d'au moins 50% de mica, et s'étend à un procédé de filature permettant d'obtenir un tel fil.The present invention relates to a wire based mica, i.e. a wire made up of at least 50% of mica, and extends to a spinning process allowing to get such a thread.
L'invention s'étend de manière complémentaire à l'utilisation d'un tel produit pour tous les usages classiques de transformation d'un fil, tels que le tissage, le tressage, etc., en vue d'obtenir essentiellement des produits à finalité industrielle.The invention extends in a complementary manner the use of such a product for all uses conventional yarn transformation, such as weaving, braiding, etc., in order to obtain essentially industrial products.
On sait que le mica relève de la classe des produits non fibreux. La filature étant définie comme l'ensemble des opérations de transformation des fibres textiles en fils, le mica ne se prête donc pas, en principe, aux opérations de filature.We know that mica belongs to the class of non-fibrous products. Spinning being defined as all fiber processing operations yarn textiles, mica is therefore not suitable, principle, to spinning operations.
Un grand nombre de produits techniques proposés actuellement sur le marché, en particulier pour des usages industriels, qui se caractérisent par de bonnes propriétés physico-chimique telles que la résistance au feu ou aux hautes températures, les propriétés isolantes etc., donnent lieu à des critiques pour des raisons de salubrité de par leur composition fibreuse.A large number of technical products currently offered on the market, in particular for industrial uses, which are characterized by good physicochemical properties such as fire resistance or at high temperatures, insulating properties etc., give rise to criticism for health reasons due to their fibrous composition.
Même des produits qui étaient jugés jusqu'à présent inertes et sans danger, par exemple les fibres de verre, les fibres céramiques et également les fibres organiques du type aramide, sont de plus en plus critiqués.Even products that were tried up to present inert and harmless, for example fibers of glass, ceramic fibers and also fibers Aramid-type organics are increasingly criticized.
Actuellement, les fibres de verre dont le diamètre est inférieur à 3 µm et qui sont fibrillisées sont considérées comme suspectes d'être potentiellement dangereuses pour la santé.Currently, glass fibers including diameter is less than 3 µm and which are fibrillated are considered suspicious of being potentially dangerous to health.
Il existe de nombreuses applications industrielles dans lesquelles cependant ces types de produits sont jugés indispensables, et il n'existe a priori actuellement pas de substituts valables pour ces produits sur le marché.There are many applications industries in which however these types of products are considered essential, and there is a priori currently no valid substitutes for these products on the market.
Des particules de mica ont déjà bien sûr été incorporées en très faible proportion dans des produits filamentaires tels que la laine à tricoter. Le but était dans ce cas de créer des effets optiques, esthétiques et décoratifs.Mica particles have of course already been incorporated in very small proportion in products filaments such as knitting wool. The goal was in this case to create optical, aesthetic and decorative.
L'invention vise à fournir un produit nouveau, qui permette d'éviter les inconvénients décrits des produits de l'état de la technique.The invention aims to provide a product new, which avoids the disadvantages described state-of-the-art products.
L'invention porte essentiellement sur un produit à base de mica, et plus spécifiquement à base de papier de mica, sous forme d'un fil. The invention relates essentially to a mica-based product, and more specifically based on mica paper, in the form of a wire.
Le terme "à base de mica" signifie que le produit comporte au moins 40%, et de préférence au moins 50%, en poids de mica.The term "mica-based" means that the product contains at least 40%, and preferably at least 50%, by weight of mica.
Le mica est un aluminosilicate de type phlogopite, muscovite ou synthétique, ou peut être constitué d'un mélange de ces différents composés.Mica is an aluminosilicate type phlogopite, muscovite or synthetic, or may be consisting of a mixture of these different compounds.
Le caractère non fibreux du mica s'opposant à la réalisation directe d'un filage, selon l'invention que le mica est mis en oeuvre avantageusement sous forme d'un "papier de mica". La notion de "papier de mica" est bien connue, et signifie que le mica, qui est un produit naturel ou synthétique est d'abord mis sous forme de paillettes et ensuite transformé par les techniques papetières pour former des feuilles. Il ne s'agit donc pas chimiquement d'un papier à base de cellulose.The non-fibrous nature of mica opposing the direct production of a spinning, according to the invention that the mica is advantageously used in the form of a "mica paper". The notion of "mica paper" is good known, and means that mica, which is a natural product or synthetic is first put in the form of glitter and then transformed by papermaking techniques to form leaves. So it's not chemically cellulose-based paper.
Pour permettre la filature, on peut renforcer le mica pour former un produit composite. Le renfort peut se présenter sous toute forme physique appropriée, comme :
- fibres : de verre ou aramide, par exemple
- non tissés : feutres ou mats
- fils
- films, de polyester ou de polyéthylène, par exemple
- tissus, de verre ou de céramique
- résines résistant aux hautes températures, par exemple de type aramide ou silicone.
- fibers: glass or aramid, for example
- non-woven: felt or mat
- son
- films, polyester or polyethylene, for example
- fabrics, glass or ceramic
- high temperature resistant resins, for example of the aramid or silicone type.
En vue de former un produit composite constitué par le papier de mica et son support, on peut avoir recours aux diverses techniques classiques telles que la stratification du papier mica sur le support mais également l'incorporation du renfort dans la masse du papier de mica. In order to form a composite product consisting of mica paper and its support, we can use various conventional techniques such as the lamination of the mica paper on the support but also the incorporation of the reinforcement in the mass of the mica paper.
Le produit obtenu peut être découpé sous forme de rubans continus.The product obtained can be cut under form of continuous ribbons.
La quantité de renfort mise en oeuvre peut être fort variable. La solidarisation du papier de mica et du renfort, soit dans le cas d'une incorporation directe de ce renfort dans la masse de mica, soit lors de la stratification, peut être accrue par la présence d'un adhésif ou d'une résine, notamment du type silicone. Vient ensuite l'opération de filage à proprement parler, qui consiste à tordre ce ruban à la valeur de titre voulue afin d'obtenir un fil simple.The amount of reinforcement used can be very variable. The joining of mica paper and reinforcement, either in the case of direct incorporation of this reinforcement in the mass of mica, either during the stratification, can be increased by the presence of a adhesive or a resin, in particular of the silicone type. Comes then the actual spinning operation, which is to twist this ribbon to the desired title value so to get a single wire.
Ce fil simple peut ensuite être transformé par toutes les techniques classiques de l'industrie textile. Il peut par exemple être retordu avec un autre fil d'une autre nature ou être mis en oeuvre directement, soit pour former des tresses (tresses à torons, tresses plates, etc.), soit pour former un tissu ou un produit à mailles, selon les techniques textiles classiques.This single wire can then be transformed by all the classic techniques of the industry textile. It can for example be twisted with another thread of another nature or be implemented directly, either to form braids (strand braids, flat braids, etc.), either to form a fabric or a mesh product, according to classic textile techniques.
Les produits textiles obtenus à partir de ce fil conviennent pour un grand nombre d'usages industriels, permettant de mettre à profit les qualités intrinsèques du mica et en particulier ses propriétés isolantes électriques et thermiques ainsi que sa résistance au feu.Textile products obtained from this wire are suitable for a large number of industrial uses, allowing to take advantage of the intrinsic qualities of mica and in particular its electrical insulating properties and thermal as well as its fire resistance.
La technique de l'invention fournit dont un produit nouveau présentant intrinsèquement de grandes possibilités d'application, en particulier d'application industrielle.The technique of the invention provides a new product with intrinsically large application possibilities, in particular application industrial.
Il est particulièrement surprenant qu'un produit ne se prêtant en principe pas à la transformation par simple filature puisse, dans les conditions de l'invention, être obtenu sous forme d'un fil régulier de titre constant et de bonne résistance mécanique. It is particularly surprising that a product not generally suitable for processing by simple spinning can, under the conditions of the invention, be obtained in the form of a regular wire of constant titer and good mechanical resistance.
Un tel fil se prête aux opérations habituelles telles que l'ensimage et également la teinture à l'aide de colorants ou de pigments. L'invention s'étend donc à toutes les applications du fil obtenu impliquant sa transformation selon les techniques textiles connues de l'homme de l'art.Such a wire lends itself to operations such as sizing and also dyeing using dyes or pigments. The invention extends therefore to all applications of the wire obtained involving its transformation according to textile techniques known from one skilled in the art.
Le mica, étant un produit minéral non fibreux et non nocif, constitue un produit potentiellement moins dangereux pour la salubrité que ceux utilisés généralement selon l'état de la technique, en particulier l'asbeste.Mica, being a non-fibrous mineral product and not harmful, is a potentially less product unsafe for food than those commonly used according to the state of the art, in particular asbestos.
