Fil résistant à la coupure, destiné notamment à la réalisation de vêtements de protection Cut resistant wire, intended in particular for the production of protective clothing
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 attack
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,It is widely known in the literature, and by US Patents 3,883,898, GB 1,586,890, US 4,777,789, US 4,004,295,
GB 2 01 8 323, DE 1 610 495, EP 0 1 1 8 898, 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.GB 2 01 8 323, DE 1 610 495, EP 0 1 1 8 898, that the combination of different fibrous materials of polymeric or inorganic origin in the family of vitreous or ceramic or metallic compounds are used for the purpose of reinforcement of threads intended for protection 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 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. 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. Les fils en polymères purs, choisis dans les matériaux précédents ne permettent pas d'obtenir des classements en classe 5 selon la norme européenne EN 388, 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.These parts of protective equipment must have very good mechanical characteristics, in particular to shear stresses, without losing the flexibility and lightness necessary for good dexterity. Generally found as materials used particular polymers such as Polyamides, Para-aramides, High molecular weight polyethylenes, LCP fibers (Liquid Crystal Polymer), Polybensimidizoasole, Polyester loaded with ceramic. These materials have in common the characteristic of being very crystalline and consequently of possessing a fairly high intrinsic hardness. Indeed, the hardness of the materials used is very important, and largely governs the cutting or shearing mechanisms to which they are exposed. As an indication, crystalline and semi-crystalline polymeric materials have hardnesses measured on the Mohs scale of between 2 and 3 units. The pure polymer yarns, chosen in the previous materials do not allow obtaining class 5 classifications according to the European standard EN 388, for thin knits, ensuring good dexterity as must be the case in protective gloves. intended for cutting. These personal protective equipment, widely used in the sheet metal industry must allow beyond good grip 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 EN 388, 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. Les produits proposés présentent deux inconvénients majeurs :In order to resolve the compromise which makes it possible to produce both flexible, light and therefore comfortable gloves, while being classified in class 5 according to EN 388, many companies incorporate inorganic filaments, in combination with polymeric filaments. Glass and stainless steel are generally used to reinforce without excessively weighing down the wires intended for the production of protective gloves against cuts. The Mohs hardness of steel is 5 units, that of glass 6/7 units. 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 do not withstand bending well and break. The released ends, despite assemblies of polymeric filaments intended to sheath them by wrapping operations, end up passing through the layers of gimped polymeric filaments, the effect of which is to prick the hands of operators, who generally no longer carry the equipment protection.
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 solve this problem, a glass treatment process, existing in the sun visor industry, has been used. In this area, glass filaments are used for their fire-resistant properties (MO classification). These sun visors are placed inside buildings in front of windows and must fulfill, in addition to solar filtration, an aesthetic function. For these purposes, the glass filament generally called silionne is coextruded with a polymeric flame-retardant resin in the mass and dyed with the desired color. These threads are then woven and heat-welded at the crossing of the threads to block the thread network.
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. 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 silionne 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 guipée par des multifilaments de synthèse. Avantageusement, l'âme subit un double ou un triple guipage par des multifilaments de synthèse.The object of the invention is to provide a wire resistant to cutting allowing the production of protective equipment which provides good security for users and which has good flexibility, promoting comfort. To this end, the wire which it concerns, comprising a core obtained by coextrusion of a glass multifilament E, R, C or S or more generally of silionne or basalt and a sheath of polymer of the thermoplastic, thermoset type , natural elastomer, synthetic elastomer, fluorinated or not, is characterized in that the fiberglass part represents at most 60% by mass of the sheath + filament compound, and in that the core is covered by synthetic multifilaments. Advantageously, the core is subjected to a double or triple wrapping by synthetic multifilaments.
La part de coextrusion rend le fil d'âme plus souple que s'il était entièrement réalisé en verre. En outre, les fils de guipage sont absolument bloqués par le contact du polymère les constituant sur le polymère coextrudé.The coextrusion part makes the core wire more flexible than if it were made entirely of glass. In addition, the covering threads are absolutely blocked by the contact of the polymer constituting them on the coextruded polymer.
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.This produces knitted products which achieve very high abrasion resistance. Another substantial advantage is the protection of the glass filament against the attack of chemicals, in particular hydrofluoric acid, in certain sectors of the chemical or related industry.
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 polyurethanes 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.In terms of cutting performance, level 5 is reached very easily and can be stored even after 10 washes.
Suivant une caractéristique de ce fil, les multifilaments de guipage 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 covering multifilaments are chosen from the following families: High molecular weight polyethylene, greater than 600,000 g / mole, Para-aramid with a module> 50Gpa, high tenacity and standard polyamide, High tenacity polyester and standard, Liquid crystal polymer (LCP), Poly Phenylene Benzo Bisoxazole (PBO), Polyester loaded with ceramic.
Selon une forme de réalisation, les différents multifilaments de guipage sont constitués de matériaux identiques.According to one embodiment, the different covering multifilaments are made of identical materials.
Selon une autre forme de réalisation, les différents multifilaments de guipage sont constitués, au moins pour certains, de matériaux différents.According to another embodiment, the different covering multifilaments are made, at least for some, of different materials.
