Description

La présente invention a pour objet un fil résistant à la coupure, destiné notamment à la réalisation de vêtements de protection contre les agressions mécaniquesThe present invention relates to a cut resistant wire, intended in particular for the production of protective clothing against mechanical assaults

Il est largement connu dans la littérature, et par les brevets US 3 883 898, GB 1 586 890, US 4 777 789, US 4 004 295, GB 2 018 323, DE 1 610 495, EP 0 118 898, que la combinaison de différents matériaux fibreux d'origine polymérique, ou inorganique dans la famille des composés vitreux ou céramique, ou métalliques, sont employés à des fins de renforcement de fils destinés au domaine de la protection contre les agressions mécaniques et/ou la perforation.It is widely known in the literature, and by patents US 3,883,898, GB 1,586,890, US 4,777,789, US 4,004,295, GB 2 018 323, DE 1 610 495, EP 0 118 898, that the combination of different fibrous materials of polymeric, or inorganic origin in the family of glassy or ceramic or metallic compounds are used for reinforcing wires intended for the protection sector against mechanical attack and / or puncture.

Ces équipements de protection individuelle se présentent le plus souvent sous forme de gants, de manchettes, de tabliers, ou toute partie de vêtement, et sont généralement tricotés ou plus rarement tissés.These personal protective equipment are the most often in the form of gloves, cuffs, aprons, or any part of clothing, and are generally knitted or more rarely woven.

Ces parties d'équipements de protection doivent posséder de très bonnes caractéristiques mécaniques, en particulier aux sollicitations de cisaillement, sans perdre la souplesse et la légèreté nécessaires à une bonne dextérité.These parts of protective equipment must have very good mechanical properties, in particular when stressed shear, without losing the flexibility and lightness necessary for good dexterity.

Généralement on trouve comme matériaux employés des polymères particuliers comme les Polyamides, Para-aramides, Polyéthylènes à haut poids moléculaire, des fibres LCP (Liquid Crystal Polymère), le Polybensimidizoasole, le Polyester chargé de céramique. Ces matériaux ont en commun la particularité d'être très cristallins et par conséquent de posséder une dureté intrinsèque assez importante. En effet, la dureté des matériaux utilisés est très importante, et gouverne largement les mécanismes de tranchage ou de cisaillement auxquels ils sont exposés. A titre indicatif, les matériaux polymériques cristallins et semi-cristallins ont des duretés mesurées sur l'échelle de Mohs comprises entre 2 et 3 unités.Generally found as materials used special polymers such as Polyamides, Para-aramides, High molecular weight polyethylene, LCP (Liquid Crystal) fibers Polymer), Polybensimidizoasole, Polyester loaded with ceramic. These materials have in common the characteristic of being very crystalline and by therefore have a fairly high intrinsic hardness. Indeed, the hardness of the materials used is very important, and largely governs the slicing or shearing mechanisms to which they are exposed. As an indication, crystalline and semi-crystalline polymeric materials have hardnesses measured on the Mohs scale between 2 and 3 units.

Les fils en polymères purs, choisis dans les matériaux précédents ne permettent pas d'obtenir des classements en classe 5 selon la norme européenne EN388, pour des tricots peu épais, assurant une bonne dextérité comme cela doit être le cas dans les gants de protection destinés à la coupure. Ces équipement de protection individuelle, très utilisés dans le domaine de la tôlerie doivent permettre au-delà de la bonne préhension par les utilisateurs, un bon confort qui assure que l'équipement sera toujours porté par les personnels exposés. Pure polymer yarns, chosen from the materials previous do not allow to obtain class 5 classifications according to the European standard EN388, for thin knits, ensuring good dexterity as must be the case in protective gloves intended for cutting. These personal protective equipment, very used in sheet metal work must allow beyond good gripping by users, good comfort which ensures that the equipment will always be worn by exposed personnel.

Afin de résoudre le compromis qui permet de réaliser à la fois des gants souples, légers, donc confortables, tout en étant classés en classe 5 selon EN388, de nombreuses sociétés incorporent des filaments inorganiques, en combinaison avec des filaments polymériques. Le verre et l'acier inoxydable sont généralement utilisés pour renforcer sans trop les alourdir les fils destinés à la réalisation des gants de protection contre les coupures. La dureté Mohs de l'acier est 5 unités, celle du verre 6/7 unités.In order to resolve the compromise that makes it possible to achieve both soft, light, therefore comfortable gloves, while being classified in class 5 according to EN388, many companies incorporate filaments inorganic, in combination with polymeric filaments. Glass and stainless steel is generally used to reinforce without too much weighing down the threads intended for the production of protective gloves against cuts. The Mohs hardness of steel is 5 units, that of glass 6/7 units.

Les produits proposés présentent deux inconvénients majeurs :The products offered have two major drawbacks:

Les filaments de verre ou d'acier inoxydable résistent mal à la pliure et se rompent. Les extrémités libérées, malgré des montages de filaments polymères destinés à les gainer par des opérations de guipage, finissent par traverser les couches des filaments polymères guipés, dont l'effet est de piquer les mains des opérateurs, qui généralement ne portent plus l'équipement de protection.Glass or stainless steel filaments are poorly resistant to kink and break. The ends released, despite mounting of polymeric filaments intended to sheath them by wrapping operations, eventually pass through the layers of gimped polymer filaments, of which the effect is to prick the hands of operators, who generally do not wear plus protective equipment.

Afin de résoudre ce problème, un procédé de traitement du verre, existant dans l'industrie des pare-soleil a été mis à profit. Dans ce domaine, les filaments de verre sont utilisés pour leurs propriétés non feu (classement MO). Ces pare-soleil sont placés à l'intérieur des bâtiments devant les fenêtres et doivent remplir en plus de la filtration solaire, une fonction esthétique. A ces fins, le filament de verre généralement nommé silionne est coextrudé avec une résine polymérique ignifugée dans la masse et teintée au coloris souhaité. Ces fils sont ensuite tissés et thermosoudés au croisement des fils pour bloquer le réseau de fils.In order to resolve this problem, a method of processing the glass, existing in the sun visor industry has been taken advantage of. In this field, glass filaments are used for their flame retardant properties (MO classification). These sun visors are placed inside buildings in front of the windows and must fill in addition to solar filtration, a aesthetic function. For these purposes, the glass filament generally named silionne is coextruded with a bulk flame retardant polymer resin and tinted to the desired color. These threads are then woven and heat sealed at the crossing of the wires to block the network of wires.

Le but de l'invention est de fournir un fil résistant à la coupure permettant la réalisation d'un équipement de protection qui offre une bonne sécurité pour les utilisateurs et qui possède une bonne souplesse, favorisant le confort.The object of the invention is to provide a wire resistant to cutting allowing the realization of a protective equipment which offers a good security for users and which has good flexibility, promoting comfort.

A cet effet, le fil qu'elle concerne, comprenant une âme obtenue par coextrusion d'un multifilament de verre E, R, C ou S ou plus généralement de silione ou de basalte et d'une gaine de polymère du type thermoplastique, thermodur, élastomère naturel, élastomère synthétique fluoré ou non, est caractérisé en ce que la partie fibre de verre représente au maximum 60% en masse du composé gaine + filament, et en ce que l'âme est assemblée ou retordue avec des filés de fibres composés de fibres de synthèse. To this end, the wire which it relates, comprising a core obtained by coextrusion of a glass multifilament E, R, C or S or more generally silione or basalt and a polymer sheath of the type thermoplastic, thermoset, natural elastomer, synthetic elastomer fluorinated or not, is characterized in that the fiberglass part represents maximum 60% by mass of the sheath + filament compound, and in that the core is assembled or twisted with yarns of fibers composed of synthetic fibers.

L'âme et les filés de fibres composés de fibres de synthèse sont soit assemblés soit retordus ensemble en sens "S" ou "Z".The core and yarns of fibers composed of synthetic fibers are either assembled or twisted together in "S" or "Z" directions.

La part de coextrusion rend le fil d'âme plus souple que s'il était entièrement réalisé en verre. En outre, les filés de fibres sont absolument bloqués par le contact du polymère les constituant sur le polymère coextrudé.The coextrusion part makes the core thread more flexible than if it were entirely made of glass. In addition, fiber yarns are absolutely blocked by the contact of the polymer constituting them on the polymer coextruded.

On obtient ainsi des produits tricotés qui atteignent de très fortes résistances à l'abrasion. Un autre avantage substantiel est la protection du filament de verre contre l'agression de produits chimiques en particulier l'acide fluorhydrique, dans certains secteurs de l'industrie chimique ou connexe.We thus obtain knitted products which reach very high abrasion resistance. Another substantial advantage is the protection of the glass filament against the aggression of chemicals in particularly hydrofluoric acid, in certain sectors of industry chemical or related.

La gaine extrudée de polymère crée une étanchéité parfaite pour le composant axial constitué par le filament de verre. Les polymères utilisés peuvent être des polychlorures de vinyle ou polyuréthanes ou tout autre polymère inerte chimiquement.The extruded polymer sheath creates a perfect seal for the axial component constituted by the glass filament. The polymers used can be polyvinyl chloride or polyurethane or any other chemically inert polymer.

Au niveau de la performance coupure, le niveau 5 est atteint très facilement et se conserve même après 10 lavages.At cutoff performance level 5 is reached very easily and keeps even after 10 washes.

Suivant une caractéristique de ce fil, les filés de fibres sont choisis parmi les familles suivantes : Polyéthylène à haut poids moléculaire, supérieur à 600 000 g/mole, Para-aramide de module > 50Gpa, polyamide haute ténacité et standard, Polyester haute ténacité et standard, Polymère cristal liquide (LCP), Poly Phénylène Benzo Bisoxazole (PBO), Polyester chargé de céramique.According to a characteristic of this yarn, the fiber yarns are chosen from the following families: High molecular weight polyethylene, greater than 600,000 g / mole, Para-aramid with a module> 50Gpa, polyamide high tenacity and standard, High tenacity and standard polyester, Polymer liquid crystal (LCP), Poly Phenylene Benzo Bisoxazole (PBO), Polyester loaded with ceramic.

Selon une forme de réalisation, les filés de fibres sont constitués de matériaux identiques.According to one embodiment, the fiber yarns are made of identical materials.

Selon une autre forme de réalisation, les filés de fibres sont constitués, au moins pour certains, de matériaux différents.According to another embodiment, the fiber yarns are made, at least for some, of different materials.

Suivant une possibilité, les filés de fibres comprennent de plus des fibres appartenant au règne végétal ou animal.According to one possibility, the fiber yarns further comprise fibers belonging to the vegetable or animal kingdom.
