The core is covered with multi-filament(s) (2) of low melting point material, and the assembly is heat treated to bond the covering to the core and act as a protective sleeve. The heat treatment is applied by an electric oven at a temperature of 150 - 250 [deg]C. The yarn is made from a core filament (1) of a material that ensures a required mechanical strength, fire resistance or resistance to cutting, such as stainless steel or glass fibre, or a combination of the two, either parallel or twisted. The core, which can also incorporate a filament that provides elasticity, is covered with at least one multi-filament (2) of a low melting point material, and the assembly is heat treated to bond the covering to the core and act as a protective sleeve. The heat treatment can be applied by an electric oven at a temperature of 150 - 250 [deg]C. An independent claim is included for a process of manufacturing the reinforced textile yarn.

Description

L'invention concerne un fil textile renforcé afin de résister notammentThe invention relates to a reinforced textile yarn in order to withstand

aux coupures.to cuts.

Ce fil peut avantageusement être utilisé pour la réalisation de 5 vêtements de protection notamment pour la réalisation de gants anticoupures.  This thread may advantageously be used for producing protective clothing, in particular for making cut-out gloves.

Il est parfaitement connu pour un homme du métier que dans le domaine de l'anti-coupure, il est possible d'utiliser des filaments de verre 10 ou d'acier inoxydable afin de constituer un renfort. Les produits tricotés à partir de ce type de fil renforcé, présentent une certaine épaisseur susceptible de nuire par conséquent au confort.  It is well known to a person skilled in the art that in the field of anti-cut, it is possible to use glass filaments 10 or stainless steel to form a reinforcement. The knitted products from this type of reinforced yarn have a certain thickness which may therefore be detrimental to comfort.

On a également proposé d'assurer le renforcement en utilisant une fibre, notamment en KEVLARO ou DYNEEMA O permettant par conséquent de diminuer l'épaisseur du produit obtenu. Toutefois, la résistance n'est pas satisfaisante.  It has also been proposed to reinforce using a fiber, in particular KEVLARO or DYNEEMA O, thereby making it possible to reduce the thickness of the product obtained. However, the resistance is not satisfactory.

On observe également qu'un simple guipage du filament d'acier 20 inoxydable, ne peut pas être considéré comme satisfaisant, étant donné que le filament a tendance à ressortir, avec les inconvénients en résultant.  It is also observed that a simple wrapping of the stainless steel filament can not be considered satisfactory since the filament tends to stand out, with the resulting disadvantages.

On connaît également un fil résistant à la coupure destiné notamment à la réalisation de vêtements de protection pour les agressions mécaniques, comme il ressort de l'enseignement du brevet FR 2.828.894. Ce fil comprend une âme obtenue par coextrusion d'un multifilament de verre et d'une gaine de polymères dans laquelle la partie fibre de verre représente au maximum 60 % en masse du composé gaine + filament, tandis que l'âme est guipée par des multifilaments de synthèse.  Also known is a cut-resistant yarn intended in particular for the production of protective clothing for mechanical aggression, as is clear from the teaching of FR 2,828,894. This wire comprises a core obtained by coextrusion of a glass multifilament and a polymer sheath in which the fiberglass portion represents at most 60% by weight of the sheath + filament compound, while the core is guiped by synthetic multifilaments.

Cette solution ne peut pas être considérée comme satisfaisante. . Le fil est trop gros et trop rigide, ce qui entraîne un manque de dextérité pour le produit final.  This solution can not be considered satisfactory. . The wire is too big and too rigid, resulting in a lack of dexterity for the final product.

L'invention s'est fixée pour but de remédier à ces inconvénients, de manière simple, sûre, efficace et rationnelle.  The object of the invention is to remedy these disadvantages in a simple, safe, effective and rational manner.

Le problème que se propose de résoudre l'invention est de réaliser un fil renforcé fin, performant à la coupure et confortable, en étant apte à présenter une certaine souplesse et élasticité, en ayant pour objectif notamment de pouvoir associer des filaments de verre ou d'acier inoxydable avec une matière permettant d'obtenir une élasticité suffisante.  The problem to be solved by the invention is to produce a thin reinforced wire, efficient at cutting and comfortable, being able to have a certain flexibility and elasticity, with the aim in particular to be able to combine glass or glass filaments. stainless steel with a material to obtain sufficient elasticity.

Pour résoudre un tel problème, il a été conçu et mis au point un procédé de fabrication d'un fil textile renforcé, selon lequel: - on utilise une âme avec un fil sélectionné dans un matériau apte à assurer une résistance à la coupure - on recouvre l'âme d'au moins un multifilament à bas point de fusion; 20 - on soumet l'ensemble à un traitement thermique apte à assurer une liaison des différents composants.  To solve such a problem, it has been designed and developed a method for manufacturing a reinforced textile yarn, according to which: a core is used with a selected yarn in a material capable of ensuring a cut resistance; covers the core of at least one low melting point multifilament; The whole is subjected to a heat treatment capable of ensuring a bonding of the various components.

Compte tenu des caractéristiques à la base de l'invention, d'une manière importante, on combine le fil renforcé obtenu avec d'autres fils aptes à conférer une élasticité ou autres propriétés, telles que le confort, la résistance thermique, l'hydrophobie.  In view of the basic characteristics of the invention, it is important to combine the reinforced yarn obtained with other yarns capable of imparting elasticity or other properties, such as comfort, heat resistance and hydrophobicity. .

2866354 3 Dans une forme de réalisation, on utilise le fil renforcé obtenu en couverture d'une âme du type élasthanne; on recouvre l'ensemble d'un fil de filaments ou d'un filé de fibres.  In one embodiment, the reinforced yarn obtained is used to cover an elastane type core; the whole is covered with a thread of filaments or a yarn of fibers.

Des résultats satisfaisants ont été obtenus lorsque l'on soumet l'ensemble à un traitement thermique compris entre 150 C et 250 C environ à une vitesse d'environ 10 m/mn.  Satisfactory results have been obtained when the assembly is subjected to a heat treatment of between about 150 ° C. and 250 ° C. at a speed of about 10 m / min.

Selon d'autres caractéristiques, le multifilament à bas point de fusion 10 est un polypropylène. L'âme est un fil de verre ou d'acier inoxydable.  According to other features, the low melting point multifilament is polypropylene. The soul is a glass or stainless steel wire.

L'invention concerne également un fil renforcé obtenu par le procédé revendiqué en présentant une âme centrale en fil de verre ou d'acier inoxydable, recouvert par une gaine résultant de la fusion d'au moins un multifilament.  The invention also relates to a reinforced yarn obtained by the process claimed by having a central core made of glass wire or stainless steel, covered by a sheath resulting from the melting of at least one multifilament.

Enfin, l'invention concerne l'utilisation du fil renforcé pour la réalisation de vêtements de protection notamment de gants anti-coupures.  Finally, the invention relates to the use of reinforced thread for the production of protective clothing including cut-resistant gloves.

L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés dans lesquels: - la figure 1 est une vue à caractère purement schématique montrant les principales phases du procédé pour l'obtention du fil renforcé selon l'exemple de réalisation; - la figure 2 est une vue à caractère purement schématique montrant l'utilisation du fil renforcé selon l'invention, en association d'autres fils, notamment l'élasthanne, afin d'obtenir une élasticité suffisante; - la figure 3 est un exemple de réalisation d'un fil renforcé obtenu selon les caractéristiques du procédé de l'invention.  The invention is explained below in more detail with the help of the figures of the accompanying drawings, in which: FIG. 1 is a purely schematic view showing the main phases of the process for obtaining the reinforced wire according to FIG. exemplary embodiment; - Figure 2 is a purely schematic view showing the use of the reinforced wire according to the invention, in combination with other son, including elastane, to obtain sufficient elasticity; - Figure 3 is an embodiment of a reinforced wire obtained according to the characteristics of the method of the invention.

Comme le montre la figure 1, on utilise une âme (1) composée d'un fil sélectionné dans un matériau apte à assurer une résistance à la coupure. D'une manière connue, ce fil peut être un filament de verre ou d'acier inoxydable.  As shown in Figure 1, a core (1) is used composed of a selected wire in a material capable of providing a cut resistance. In a known manner, this wire may be a filament of glass or stainless steel.

Le fil (1) est ensuite recouvert, par tout matériau approprié, d'au moins un multifilament (2) à bas point de fusion, du type polypropylène par exemple.  The wire (1) is then covered, by any suitable material, with at least one low melting point multifilament (2), of the polypropylene type, for example.

L'ensemble obtenu (âme (1) + multifilament (2)) est soumis à un traitement thermique (3) apte à assurer une liaison des différents composants. A noter qu'au cours de cette opération, une deuxième couverture (4) peut être utilisée pour améliorer le gainage, le confort et/ou les propriétés du fil.  The assembly obtained (core (1) + multifilament (2)) is subjected to a heat treatment (3) capable of ensuring a connection of the various components. Note that during this operation, a second cover (4) can be used to improve the cladding, comfort and / or properties of the wire.

Pour assurer le traitement thermique, on peut utiliser un four électrique sans contact monté à une température entre 150 C et 250 C environ. Des résultats avantageux ont été obtenus avec une température de 170 C. L'ensemble du fil est soumis à l'action d'organes délivreurs (5) pour être entraîné à une vitesse linéaire d'environ 10m/mn. A la sortie de l'unité de fabrication, le fil renforcé peut être conditionné sur une bobine (6) par exemple.  To ensure the heat treatment, can be used a non-contact electric oven mounted at a temperature between 150 C and 250 C. Advantageous results were obtained with a temperature of 170 C. The whole of the wire is subjected to the action of delivery members (5) to be driven at a linear speed of about 10 m / min. At the output of the manufacturing unit, the reinforced wire can be packaged on a coil (6) for example.

Le fil obtenu selon les caractéristiques de l'invention, peut avantageusement être combiné avec d'autres fils notamment en élasthanne ou toute autre matière permettant d'obtenir une élasticité suffisante ou d'autres propriétés Par exemple, comme le montre la figure 2, on peut utiliser une âme (7) du type élasthanne que l'on recouvre du fil renforcé (6), selon les caractéristiques de l'invention, avec éventuellement une deuxième couverture (8). Cette deuxième couverture (8) peut être un filament ou filé de fibres. Le fil obtenu (9) permet d'atteindre une masse linéique faible, avec un confort amélioré résultant de l'élasticité.  The yarn obtained according to the characteristics of the invention may advantageously be combined with other yarns in particular elastane or any other material which makes it possible to obtain sufficient elasticity or other properties. For example, as shown in FIG. may use a core (7) of the elastane type which is covered with reinforced wire (6), according to the characteristics of the invention, with possibly a second cover (8). This second cover (8) may be a filament or spun fiber. The yarn obtained (9) achieves a low linear density, with improved comfort resulting from the elasticity.

Compte tenu des caractéristiques de l'invention, le fil obtenu peut avantageusement être utilisé pour la réalisation de vêtements de protection, notamment de gants anti-coupures.  Given the characteristics of the invention, the wire obtained can advantageously be used for the production of protective clothing, including cut-resistant gloves.

Les avantages ressortent bien de la description.  The advantages are apparent from the description.
