Description

PROCEDE DE FABRICATION D'UN VETEMENT DE PROTECTION ET LE VETEMENT OBTENU PAR LE PROCEDEMETHOD OF MANUFACTURING A PROTECTIVE GARMENT AND THE GARMENT OBTAINED BY THE METHOD
La présente invention concerne un procédé de fabrication d'un vêtement de protection, tel qu'un gant, tablier, gilet ou autre, ou d'une partie d'un tel vêtement, comprenant une nappe de particules métalliques assemblées entre elles.The present invention relates to a method of manufacturing a protective clothing, such as a glove, apron, vest or other, or part of such a garment, comprising a sheet of metal particles assembled together.
Les vêtements de protection utilisés dans certaines industries (notamment l'industrie de la viande) ou pour la protection des personnes contre les agressions par projectiles (balles, etc.) ou armes blanches, utilisent fréquemment des nappes de particules métalliques appréciées en particulier pour leurs qualités intrinsèques de résistance à la coupure ou à la perforation.Protective clothing used in certain industries (especially the meat industry) or for the protection of persons against projectile attack (bullets, etc.) or knives, frequently uses metal particle sheets which are particularly valued for their use. intrinsic qualities of resistance to cutting or perforation.
Ces nappes de particules métalliques consistent en des tissus de cotte de mailles formés par entrelacement d'anneaux métalliques, ou en un assemblage de plaquettes métalliques au moyen d'anneaux également métalliques. Très généralement, ces particules (anneaux et/ou plaquettes) sont réalisées en acier inoxydable ou en aluminium.These metal particle plies consist of chainmail fabrics formed by interlacing metal rings, or an assembly of metal plates by means of also metal rings. Very generally, these particles (rings and / or platelets) are made of stainless steel or aluminum.
Etant donné la fonction protectrice recherchée, on souhaite obtenir des nappes ayant des caractéristiques de résistance et de sécurité optimales.Given the protective function sought, it is desired to obtain webs having optimum strength and safety characteristics.
Cependant, les techniques de fabrication des nappes, et en particulier les opérations nécessaires de découpe, d'emboutissage, de mise en forme, de cintrage et/ou de soudage des particules métalliques, limitent les possibilités d'utiliser des métaux très durs et très résistants.However, the techniques of manufacture of the sheets, and in particular the necessary operations of cutting, stamping, shaping, bending and / or welding of the metal particles, limit the possibilities of using very hard and very hard metals. resistant.
Ainsi, jusqu'à maintenant, dans le secteur technique concerné, on utilise des aciers (316L, 304L, etc.) ou des alliages d'aluminium (séries 3000 et 5000, par exemple AG 3 (5754)), dont les caractéristiques de résistance et de dureté sont à la limite des possibilités de découpe, de façonnage et de soudage des particules constitutives des nappes précitées.Thus, until now, in the technical sector concerned, use is made of steels (316L, 304L, etc.) or aluminum alloys (3000 and 5000 series, for example AG 3 (5754)), whose characteristics of Resistance and hardness are at the limit of the possibilities of cutting, shaping and welding of the constitutive particles of the aforementioned sheets.
On n'utilise pas de métaux très durs et très résistants qui seraient susceptibles de permettre l'obtention de nappes ayant des propriétés de résistance et de dureté supérieures aux nappes classiques, ou ayant des propriétés similaires mais dont le poids serait inférieur du fait de l'utilisation d'une épaisseur moindre.Very hard and very strong metals are not used which would be able to obtain sheets having properties of resistance and hardness superior to conventional sheets, or having similar properties but whose weight would be lower because of the use of a lesser thickness.
La présente invention propose de remédier à cet inconvénient en utilisant, à titre de matériau de base, pour la fabrication des particules métalliques, un métal (ou des métaux) à durcissement structural, c'est-à-dire qui, dans un certain état, présente des caractéristiques de résistance et de dureté relativement peu élevées et en tout cas compatibles avec les opérations de découpe et de façonnage des particules métalliques (et éventuellement de mise en forme de la nappe métallique), et qui, après traitement thermique, présente des caractéristiques de résistance beaucoup plus élevées, et en particulier supérieures à celles compatibles avec les opérations de découpage/façonnage (et éventuellement de mise en forme) précitées.The present invention proposes to remedy this disadvantage by using, as a base material, for the manufacture of metal particles, a metal (or metals) with a structural hardening, that is to say which, in a certain state , has characteristics of resistance and hardness relatively low and in any case compatible with the operations of cutting and forming the metal particles (and possibly shaping the metal sheet), and which after heat treatment, has much higher strength characteristics, and in particular greater than those compatible with cutting operations / shaping (and possibly shaping) above.
Le traitement thermique en question est avantageusement réalisé après un façonnage le plus poussé possible des particules métalliques ou de la nappe métallique, en fonction de la structure souhaitée dans le vêtement que l'on désire obtenir au final.The heat treatment in question is advantageously carried out after as far as possible shaping of the metal particles or the metal sheet, depending on the desired structure in the garment that it is desired to obtain in the end.
De manière intéressante, dans le cadre d'une nappe intégralement réalisée en matériau métallique à durcissement structural (par exemple une nappe d'anneaux type cotte de mailles ou plaquettes assemblées par des anneaux de jonction), le traitement thermique est avantageusement mis en œuvre sur ladite nappe finie, après assemblage de ses particules métalliques constitutives.Interestingly, in the context of a ply integrally made of metal material with a structural hardening (for example a layer of rings such as chainmail or platelets assembled by joining rings), the heat treatment is advantageously implemented on said finished web, after assembly of its constituent metal particles.
Dans le cadre de la présente invention, le traitement thermique peut encore être réalisé sur les particules métalliques façonnées et individuelles (en particulier dans le cadre de plaquettes métalliques utilisées pour former la nappe), ces particules étant ensuite seulement assemblées pour former la nappe.In the context of the present invention, the heat treatment can also be performed on shaped and individual metal particles (in particular in the context of metal plates used to form the sheet), these particles then being only assembled to form the sheet.
Eventuellement, la nappe traitée thermiquement peut ne pas se présenter complètement dans la forme qui sera utilisée pour la fabrication du vêtement final. Dans ce cas, la nappe correspondante sera finalisée par toute technique appropriée à la résistance et à la dureté des particules métalliques. Par exemple, si cette finalisation de conformation nécessite la mise en place d'anneaux de solidarisation métalliques, ces anneaux pourront être réalisés en un acier inoxydable classique, ayant des propriétés répondant aux normes en vigueur et apte à être cintré, sans que cela nuise de manière prépondérante à la résistance de l'ensemble de la nappe. De préférence, avant façonnage des particules métalliques ou de la nappe, selon le cas, le métal en question est soumis à une opération mécanique de déformation/allongement, de type corroyage, qui permet d'obtenir un écrouissage dudit métal, adapté pour venir en limite des possibilités de façonnage desdites particules (en fonction des installations et techniques à disposition). Cette particularité permet d'optimiser l'opération ultérieure de traitement thermique pour obtenir des caractéristiques de résistance et de dureté les plus élevées possibles.Optionally, the thermally treated web may not be completely in the form that will be used for the manufacture of the final garment. In this case, the corresponding web will be finalized by any technique appropriate to the strength and hardness of the metal particles. For example, if this conformation finalization requires the establishment of metal fastening rings, these rings can be made of a conventional stainless steel, having properties that meet the standards in force and can be bent without affecting preponderant way to the resistance of the entire web. Preferably, before shaping of the metal particles or of the sheet, as the case may be, the metal in question is subjected to a mechanical deformation / stretching operation, of the wrought type, which makes it possible to obtain a work-hardening of said metal, adapted to come into operation. limit of the possibilities of shaping of said particles (according to the installations and techniques available). This feature makes it possible to optimize the subsequent heat treatment operation to obtain the highest possible resistance and hardness characteristics.
Tout type de métal à durcissement structural peut être utilisé, à partir du moment où ses caractéristiques de résistance et de dureté, avant traitement thermique, permettent la mise en forme des particules métalliques, et à partir du moment où ses caractéristiques de résistance et de dureté sont optimisées après ledit traitement thermique. Ces caractéristiques de résistance et de dureté optimisées permettent au matériau obtenu d'être largement compatible avec les normes agroalimentaires (dont les énergies sont de l'ordre de 5 joules) ; elles peuvent même permettre à ce matériau d'entrer en conformité avec certaines normes relativement sévères, telles que les normes relatives aux vêtements de protection contre les armes blanches (dont les énergies en jeu se situent, suivant les niveaux, entre 25 et 60 joules).Any type of structurally hardened metal may be used, provided that its strength and hardness characteristics, prior to heat treatment, permit the shaping of the metal particles, and from the moment when its strength and hardness characteristics are optimized after said heat treatment. These characteristics of strength and hardness optimized allow the material obtained to be widely compatible with food standards (whose energies are of the order of 5 joules); they can even allow this material to come into compliance with certain relatively strict standards, such as the standards for protective clothing against knives (whose energies are, depending on the level, between 25 and 60 joules) .
A titre d'exemple, on peut utiliser un acier inoxydable à durcissement structural issu de la recherche sur la nanotechnologie, qui utilise le principe des nanoparticules se formant lors du traitement thermique du matériau. Ces nanoparticules extrêmement dures confèrent au matériau à la fois dureté et résistance, deux propriétés normalement opposées en physique.For example, one can use a structural hardening stainless steel from nanotechnology research, which uses the principle of nanoparticles formed during the heat treatment of the material. These extremely hard nanoparticles give the material both hardness and strength, two normally opposite properties in physics.
Ce type d'acier possède aussi d'intéressantes qualités de résistance à l'abrasion et de ductilité avant traitement thermique.This type of steel also has interesting qualities of resistance to abrasion and ductility before heat treatment.
Encore à titre d'exemple on peut utiliser - un acier inoxydable de type Z 8 CNT 17.7 (norme AFNOR), ou - un alliage d'aluminium des séries 2000, 6000 et 7000 (en particulier 7075).Still as an example can be used - a stainless steel type Z 8 CNT 17.7 (AFNOR standard), or - an aluminum alloy series 2000, 6000 and 7000 (in particular 7075).
Le traitement thermique des particules métalliques ou de la nappe de particulesHeat treatment of metal particles or particle web
(ou éventuellement du vêtement semi-fini ou fini) est réalisé dans un four étanche.(or possibly semi-finished or finished garment) is made in a sealed oven.
Après mise en place du produit à traiter dans ce four, on procède à un vide d'air poussé pour éliminer au maximum l'oxygène. Ensuite, soit le traitement thermique est réalisé sous vide d'air, soit il est réalisé après remplacement de l'air par un gaz neutre, ou un mélange de gaz neutre (par exemple Argon ou Argon + Hydrogène).After placing the product to be treated in this oven, a high air vacuum is carried out to eliminate oxygen as much as possible. Then, either the heat treatment is carried out under vacuum, or it is carried out after replacement of the air with a neutral gas, or a mixture of neutral gas (for example Argon or Argon + Hydrogen).
La durée du traitement et la température de traitement seront fonction des caractéristiques du métal utilisé. Par exemple, la montée en température pourra durer une heure ; le temps de traitement pourra être de trois à six heures à une température comprise entre 400 etThe duration of the treatment and the treatment temperature will depend on the characteristics of the metal used. For example, the rise in temperature may last an hour; the treatment time may be from three to six hours at a temperature of between 400 and
6000C (fonction du métal ou des métaux utilisés), suivi d'un refroidissement d'une durée de deux à cinq heures, l'ensemble du traitement, jusqu'au refroidissement, étant réalisé sous vide d'air ou sous gaz neutre. En fonction du métal utilisé, la nappe métallique obtenue peut avoir une résistance et une dureté 1,1 à deux fois supérieure, voire plus, par rapport aux mêmes nappes réalisées avec des aciers ou aluminiums classiques.600 0 C (function of the metal or metals used), followed by cooling for a period of two to five hours, the entire treatment, until cooling, being carried out under vacuum or under neutral gas . Depending on the metal used, the metal sheet obtained can have a strength and hardness of 1.1 to twice as much, or more, compared to the same sheets made with conventional steels or aluminum.
Comme indiqué ci-avant, on peut soit mettre à profit ces caractéristiques de dureté/résistance optimales, soit développer des nappes ayant des caractéristiques de résistance et de dureté voisines de celles de l'état de la technique, mais d'un poids inférieur par unité de surface (caractéristique particulièrement importante dans le domaine du vêtement de protection).As indicated above, it is possible either to take advantage of these optimum hardness / strength characteristics, or to develop plies having strength and hardness characteristics close to those of the state of the art, but of a weight lower per unit area (a particularly important feature in the field of protective clothing).
La nappe métallique selon l'invention peut être une cotte de mailles, obtenue à partir d'un fil métallique à durcissement structural, type acier inoxydable ou alliage d'aluminium, pour réaliser le façonnage de gants de protection (avec ou sans manchette), de tabliers, par exemple pour l'industrie de la viande, ou de gilets de protection.The metal sheet according to the invention can be a coat of mesh, obtained from a wire with a structural hardening, stainless steel or aluminum alloy type, to form the shaping of protective gloves (with or without a cuff), aprons, for example for the meat industry, or protective vests.
Ces gilets peuvent être des gilets pare-balles ou pare-armes blanches dans lesquels la cotte de mailles constituera l'une des couches de protection, en association éventuelle avec une ou plusieurs épaisseurs de textile technique et/ou autre matériau classique. Cette couche de cotte de mailles sera intégrée par tout moyen approprié au sein du gilet ; elle pourra être fixée par exemple par des moyens de solidarisation amovibles type bande(s) auto-agrippante(s) ou bouton(s) pression(s).These vests may be bullet-proof vests or white-armor vests in which the chainmail will be one of the protective layers, possibly in combination with one or more thicknesses of technical textile and / or other conventional material. This coat of mail coat will be integrated by any appropriate means within the vest; it may be fixed for example by removable fastening means type tape (s) self-gripping (s) or button (s) pressure (s).
La nappe selon l'invention peut aussi être constituée de plaquettes métalliques (de forme générale rectangulaire, circulaire ou autre) assemblées entre elles par des anneaux de jonction (ou autre moyen de jonction), pour former des tabliers de protection, notamment mais non-exclusivement pour l'industrie de la viande. Dans ce cas les plaquettes et le fil de jonction peuvent tous deux être réalisés en métal à durcissement structural, notamment de l'acier inoxydable ou un alliage d'aluminium (dans ce cas, le traitement thermique est avantageusement réalisée une fois la nappe assemblée).The sheet according to the invention may also consist of metal plates (generally rectangular, circular or other) assembled together by connecting rings (or other means of joining), to form protective aprons, including but not exclusively for the meat industry. In this case the wafers and the connecting wire may both be made of structurally hardened metal, in particular stainless steel or an aluminum alloy (in this case, the heat treatment is advantageously carried out once the layer has been assembled) .
Il est aussi envisageable d'utiliser des plaquettes en métal à durcissement structural (acier inoxydable ou alliage d'aluminium) auxquelles on fait subir le traitement thermique avant leur assemblage entre elles au moyen d'anneaux métalliques standards (ou autre moyen), notamment en acier inoxydable classique. It is also conceivable to use structurally hardened metal plates (stainless steel or aluminum alloy) to which the heat treatment is subjected before they are assembled together by means of standard metal rings (or other means), in particular classic stainless steel.
