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 yarn, intended in particular for the production of protective clothing against mechanical aggression

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 various fibrous materials of polymeric origin, or inorganic in the family of vitreous or ceramic compounds, or metal, are used for son reinforcement purposes intended for the field of protection against mechanical aggression and / or perforation.

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.These parts of protective equipment must have very good mechanical characteristics, especially at shear stresses, 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, materials used are particular polymers such as polyamides, para-aramids, high molecular weight polyethylenes, LCP (Liquid Crystal Polymer) fibers, polybensimidizoasole, ceramic-filled polyester. These materials have the particular feature of being very crystalline and therefore have a substantial 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, the crystalline and semi-crystalline polymeric materials have hardnesses measured on the Mohs scale of 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 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 par les utilisateurs, un bon confort qui assure que l'équipement sera toujours porté par les personnels exposés.The pure polymer yarns, chosen from the above materials, do not make it possible to obtain Class 5 classifications according to the European standard EN 388, for thin knitwear, ensuring good dexterity as it should be the case in protective gloves. intended for cutting. These personal protective equipment, widely used in the field of sheet metal must allow beyond the good by the users, a good comfort which ensures that the equipment will always be worn by the 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.In order to solve the trade-off that makes it possible to produce both flexible, lightweight 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 cumbersome the threads intended for the realization of the protective gloves against cuts. The Mohs hardness of steel is 5 units, that of glass 6/7 units.

Le document US 5 846 476 décrit un fil de verre guipé par des multifilaments de polymère de différentes natures, dans le but de protéger le multifilament de verre notamment de l'abrasion, tout en profitant de la grande résistance du verre à la coupure.The document US Pat. No. 5,846,476 describes a glass yarn gimped by multifilament polymers of different types, for the purpose of protecting the glass multifilament, in particular from abrasion, while taking advantage of the great resistance of the glass at cutting.

Les produits proposés présentent deux inconvénients majeurs :The proposed products have two major disadvantages:

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.The glass or stainless steel filaments are poorly resistant to creasing and break. The ends liberated, despite assemblies of polymeric filaments intended to cover them by wrapping operations, eventually pass through the layers of the gimped polymeric filaments, the effect of which is to prick the hands of the operators, who generally no longer wear 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 exploited. In this field, the glass filaments are used for their non-fire properties (MO classification). These sunshades are placed inside the buildings in front of the windows and must fulfill in addition to solar filtration, an aesthetic function. For these purposes, the glass filament generally named silionne is coextruded with a polymeric resin flame retarded in the mass and tinted to the desired color. These son are then woven and heat sealed at the crossing son to block the son 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.The object of the invention is to provide a cut resistant wire for the realization of a protective equipment that offers good security for users and has good flexibility, promoting comfort.

A cet effet, le fil qu'elle concerne, comprenant une âme comportant un multifilament de verre E, R, C ou S ou plus généralement de silionne ou de basalte, l'âme étant guipée par des multifilaments composés de fibres de synthèse, caractérisé en ce que l'âme est obtenue par coextrusion du multifilament de verre et d'une gaine de polymère du type thermoplastique, thermodur, élastomère naturel, élastomère synthétique fluoré ou non, et en ce que la partie fibre de verre représente au maximum 60% en masse du composé gaine + filament.For this purpose, the yarn it concerns, comprising a core comprising a glass multifilament E, R, C or S or more generally of silionne or basalt, the core being guiped by multifilaments composed of synthesis, characterized in that the core is obtained by coextrusion of the glass multifilament and a polymer sheath of the thermoplastic, thermoset, natural elastomer or fluorinated synthetic elastomer type, and in that the fiberglass portion represents maximum 60% by weight of the compound sheath + filament.

Avantageusement, l'âme subit un double ou un triple guipage par des multifilaments composés de fibres de synthèse.Advantageously, the core undergoes double or triple wrapping by multifilaments composed of synthetic fibers.

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 portion makes the core wire more flexible than if it were entirely made of glass. In addition, the yarns are completely 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.Knitted products are thus obtained which attain very high resistance to abrasion. Another substantial advantage is the protection of the glass filament against the aggression of chemicals, particularly 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 consisting of the glass filament. The polymers used may be polyvinyl chlorides 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 cut performance level 5 is reached very easily and can be preserved 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 > 5OGpa, 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 one characteristic of this yarn, the multifilament wraps are chosen from the following families: Polyethylene with a high molecular weight, greater than 600,000 g / mol, para-aramid> 5OGpa, high-tenacity polyamide and standard, high-tenacity polyester and Standard, Liquid Crystal Polymer (LCP), Poly Phenylene Benzo Bisoxazole (PBO), Ceramic-laden polyester.

Selon une forme de réalisation, les différents multifilaments de guipage sont constitués de matériaux identiques.According to one embodiment, the various multifilament wraps consist 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 various multifilament wraps consist, at least for some, of different materials.
