Description

Domaine de l'inventionField of the invention

La présente invention s'inscrit dans le domaine de la confection de vêtement de protection contre les agressions nucléaire, radiologique, biologique et chimique. La présente invention porte plus particulièrement sur l'assemblage par couture du vêtement de protection NRBC. L'invention est notamment applicable aux vêtements de protection intégrant une couche filtrante adsorbante. L'invention est notamment destinée à une application militaire.The present invention falls within the field of making protective clothing against nuclear, radiological, biological and chemical attack. The present invention relates more particularly to the assembly by sewing of the CBRN protective garment. The invention is particularly applicable to protective clothing incorporating an adsorbent filter layer. The invention is in particular intended for a military application.

Etat de la techniqueState of the art

Il existe de nombreux types de vêtements de protection, notamment à usage militaire. Parmi eux, les vêtements de protection contre les risques NRBC (acronyme pour Nucléaire, Radiologique, Biologique et Chimique). Ces vêtements couvrent tout ou partie du corps de l'utilisateur et sont destinés à protéger ledit utilisateur contre les effets d'agents contaminants, qu'ils soient chimiques, biologiques ou autres, notamment en évitant le contact de ces agents contaminants, qu'ils soient sous forme liquide ou gazeuse, avec la peau ou les muqueuses dudit utilisateur. Diverses gammes de vêtements de protection ont été développées, telles que par exemple les vestes, les pantalons, les combinaisons, voir par exemple US4272851 A .There are many types of protective clothing, especially for military use. Among them, protective clothing against CBRN risks (acronym for Nuclear, Radiological, Biological and Chemical). These garments cover all or part of the user's body and are intended to protect said user against the effects of contaminants, whether chemical, biological or other, in particular by avoiding contact with these contaminants, whether they are in liquid or gaseous form, with the skin or mucous membranes of said user. Various ranges of protective clothing have been developed, such as for example jackets, trousers, coveralls, see for example US4272851A .

Généralement, un vêtement de protection contre les risques NRBC se présente sous la forme de deux couches textiles superposées répondant chacune à une fonction spécifique :

  • une couche, dite externe, destinée à garantir la non-pénétration des agents contaminants sous forme liquide,
  • une couche, dite de matériau filtrant, destinée quant à elle à assurer la filtration des agents contaminants sous forme vapeur.
Generally, protective clothing against CBRN risks comes in the form of two superimposed textile layers, each responding to a specific function:
  • a so-called outer layer intended to guarantee the non-penetration of contaminants in liquid form,
  • a layer, called filtering material, intended for its part to ensure the filtration of contaminants in vapor form.

De tes vêtements sont couramment fabriqués à partir de pièces assemblées entre elles, notamment par couture.Your clothes are commonly made from pieces assembled together, in particular by sewing.

Or, il s'avère que ces coutures occasionnent un défaut de protection du vêtement de protection et laisse pénétrer les agents contaminants sous forme liquide au travers des perforations de la couture.However, it turns out that these seams cause a lack of protection of the protective garment and allow contaminants to penetrate in liquid form through the perforations of the seam.

Il existe donc un besoin de garantir une protection des vêtements de protection à usage militaire contre les risques NRBC.There is therefore a need to guarantee protection of protective clothing for military use against CBRN risks.

Exposé de l'inventionDisclosure of Invention

La présente invention a notamment pour but d'apporter une solution efficace permettant de renforcer, notamment au niveau des coutures, le vêtement de protection contre les effets des agents contaminants sous toutes ses formes, que ce soit sous forme liquide ou sous forme vapeur, tout en conservant le confort du vêtement pour l'utilisateur.The object of the present invention is in particular to provide an effective solution making it possible to reinforce, in particular at the level of the seams, the protective clothing against the effects of contaminants in all their forms, whether in liquid form or in vapor form, while maintaining the comfort of the garment for the user.

Des objectifs supplémentaires de l'invention sont que ce vêtement reste simple à confectionner.Additional objectives of the invention are that this garment remains simple to make.

A cet effet, il est proposé par la présente invention un vêtement de protection, notamment à usage militaire, contre les effets d'un agent contaminant.To this end, the present invention provides protective clothing, in particular for military use, against the effects of a contaminating agent.

Par le terme vêtement, on entend tout article couvrant au moins une partie d'un corps d'un utilisateur portant ledit article. A titre d'exemple non limitatif, le vêtement de protection peut être une veste, un pantalon, une combinaison.By the term garment is meant any article covering at least part of a body of a user wearing said article. By way of non-limiting example, the protective clothing can be a jacket, trousers, a combination.

Par agent contaminant, on entend toute substance toxique notamment chimique et/ou biologique, telle que par exemple l'ypérite.By contaminant is meant any toxic substance, in particular chemical and/or biological, such as mustard gas for example.

Le vêtement de protection est destiné notamment à un usage militaire. Il peut également être destiné à un usage civil, par exemple pour la gendarmerie, la police, les hôpitaux, les pompiers.The protective clothing is intended in particular for military use. It can also be intended for civilian use, for example for the gendarmerie, the police, hospitals, firefighters.

Le vêtement de protection comporte dans son épaisseur, d'un environnement extérieur dans lequel évolue l'utilisateur du vêtement vers le corps dudit utilisateur :

  • une couche textile, dite couche externe, configurée pour stopper la phase liquide de l'agent contaminant, présentant une double caractéristique hydrophobe et oléophobe, et perméable à l'air,
  • une couche textile, dite couche de matériau filtrant, configurée pour absorber les vapeurs provenant de l'agent contaminant, et perméable à l'air.
The protective clothing comprises in its thickness, from an external environment in which the user of the clothing moves towards the body of said user:
  • a textile layer, called the outer layer, configured to stop the liquid phase of the contaminant, having a dual hydrophobic and oleophobic characteristic, and permeable to air,
  • a textile layer, called a layer of filtering material, configured to absorb the vapors coming from the contaminant, and permeable to air.

Par couche présentant une caractéristique hydrophobe, on entend au sens de la présente description une couche qui tend à repousser l'eau, que ce soit par nature ou par traitement.By layer having a hydrophobic characteristic is meant within the meaning of the present description a layer which tends to repel water, whether by nature or by treatment.

Par couche présentant une caractéristique oléophobe, on entend au sens de la présente description une couche qui tend à repousser les huiles.By layer having an oleophobic characteristic is meant within the meaning of the present description a layer which tends to repel oils.

La couche externe est réalisée par une pluralité d'empiècements assemblés entre eux, au niveau de zones d'assemblage, par couture.The outer layer is produced by a plurality of yokes assembled together, at assembly zones, by sewing.

Par couture, on entend l'assemblage d'au moins deux pièces entre elles à l'aide d'un fil à coudre, ou fil de couture, passé dans une aiguille.By sewing, we mean the assembly of at least two parts together using a sewing thread, or sewing thread, passed through a needle.

Le vêtement de protection comporte, au niveau d'une zone d'assemblage, une couche textile dite couche de renfort, présentant une double caractéristique hydrophile et oléophile, et assemblée avec deux empiècements de la couche externe par une même couture. En d'autres termes, la couche de renfort est assemblée aux deux empiècements de la couche externe par la couture qui assemble lesdits deux empiècements.The protective garment comprises, at an assembly zone, a textile layer called the reinforcement layer, having a dual hydrophilic and oleophilic characteristic, and assembled with two inserts of the outer layer by the same seam. In other words, the reinforcement layer is joined to the two yokes of the outer layer by the seam which joins said two yokes.

Par couche présentant une caractéristique hydrophile, on entend une couche qui tend à absorber l'eau, que ce soit par nature ou par traitement.By layer having a hydrophilic characteristic is meant a layer which tends to absorb water, whether by nature or by treatment.

Par couche présentant une caractéristique oléophile, on entend une couche qui tend à absorber les huiles, que ce soit par nature ou par traitement.By layer having an oleophilic characteristic is meant a layer which tends to absorb oils, whether by nature or by treatment.

Alors que les solutions actuelles proposées dans l'état de la technique sont focalisées pour empêcher le liquide de l'agent contaminant de traverser la couche externe via les perforations des coutures, l'invention adopte une démarche totalement inverse. En effet, au lieu de chercher à repousser le liquide de l'agent contaminant et à le maintenir à l'extérieur de la couche externe, l'invention accepte que le liquide traverse la couche externe par les perforations des coutures. La couche de renfort étant assemblée par le même fil de couture que celui assemblant deux empiècements de la couche externe, le fil de couture sert alors de chemin préférentiel et guide le liquide de l'agent contaminant vers la couche de renfort qui, par sa double caractéristique hydrophile et oléophile, absorbe l'agent contaminant sous sa forme liquide.While the current solutions proposed in the state of the art are focused on preventing the liquid of the contaminant from passing through the outer layer via the perforations of the seams, the invention adopts a completely opposite approach. Indeed, instead of seeking to repel the liquid from the contaminating agent and to keep it outside the outer layer, the invention allows the liquid to pass through the outer layer through the perforations of the seams. The reinforcement layer being assembled by the same sewing thread as that assembling two yokes of the outer layer, the sewing thread then serves as a preferential path and guides the liquid of the agent contaminant towards the reinforcement layer which, by its dual hydrophilic and oleophilic characteristics, absorbs the contaminant in its liquid form.

De manière inattendue et surprenante, les inventeurs ont constaté que plus aucun liquide d'agent contaminant ne traversait le vêtement de protection.Unexpectedly and surprisingly, the inventors have found that no more contaminant liquid passes through the protective clothing.

L'ajout d'une couche de renfort hydrophile et oléophile au niveau des zones d'assemblage forme ainsi une barrière au liquide et améliore considérablement la protection du vêtement contre les effets d'agents contaminants.The addition of a hydrophilic and oleophilic reinforcement layer at the level of the assembly zones thus forms a barrier to the liquid and considerably improves the protection of the garment against the effects of contaminating agents.

La confection de ce vêtement de protection ne s'en trouve pas non plus complexifiée.The manufacture of this protective clothing is not complicated either.

Selon des modes de mise en œuvre particuliers, l'invention répond en outre aux caractéristiques suivantes, mises en œuvre séparément ou en chacune de leurs combinaisons techniquement opérantes.According to particular embodiments, the invention also responds to the following characteristics, implemented separately or in each of their technically effective combinations.

Dans des modes de réalisation particuliers de l'invention, la couche de renfort est uniquement cousue avec la couche externe.In particular embodiments of the invention, the reinforcement layer is only sewn with the outer layer.

Dans un exemple de réalisation de l'assemblage par couture, la couche de renfort est comprise entre les deux empiècements.In an exemplary embodiment of the assembly by sewing, the reinforcing layer is between the two yokes.

Dans des modes de réalisation particuliers de l'invention, deux empiècements de la couche externe sont assemblés entre eux au niveau d'une zone d'assemblage, uniquement par couture. La couche de renfort est assemblée avec lesdits empiècements par la même couture.In particular embodiments of the invention, two yokes of the outer layer are assembled together at an assembly zone, solely by sewing. The reinforcement layer is assembled with said yokes by the same seam.

Dans des modes de réalisation particuliers de l'invention, le vêtement de protection comporte une pièce additionnelle cousue sur un empiècement de la couche externe. La couche de renfort est alors assemblée à la pièce additionnelle et à l'empiècement de la couche externe par une même couture. En d'autres termes, la couche de renfort est assemblée à la pièce additionnelle et à l'empiècement de la couche externe par la couture qui assemble ladite pièce additionnelle et ledit empiècement de la couche externe.In particular embodiments of the invention, the protective garment comprises an additional piece sewn onto a yoke of the outer layer. The reinforcement layer is then assembled to the additional part and to the yoke of the outer layer by the same seam. In other words, the reinforcement layer is assembled to the additional piece and to the yoke of the outer layer by the seam which assembles said additional piece and said yoke of the outer layer.

Préférentiellement, la pièce additionnelle est une poche ou un renfort.Preferably, the additional part is a pocket or a reinforcement.

Description détaillée d'un mode de réalisation de l'inventionDetailed description of an embodiment of the invention

L'invention sera décrite dans le contexte particulier d'un de ses domaines d'application préférés dans lequel le vêtement de protection est un vêtement de protection NRBC, destiné notamment à un usage militaire ou à un usage civil.The invention will be described in the particular context of one of its preferred fields of application in which the protective clothing is CBRN protective clothing, intended in particular for military use or for civilian use.

L'invention est principalement destinée, sans que ce soit limitatif de l'invention, à toute personne pouvant être amenée à utiliser un tel vêtement de protection dans le cadre de son activité professionnelle, tel que par exemple un militaire, un gendarme, un policier, un médecin, un pompier.The invention is mainly intended, without this being limiting of the invention, to any person who may be required to use such protective clothing in the context of his professional activity, such as for example a soldier, a gendarme, a policeman , a doctor, a firefighter.

Un tel vêtement de protection est destiné à protéger l'utilisateur le portant, notamment lorsque ledit utilisateur doit évoluer dans un environnement extérieur vicié par des agents contaminants, tels que par exemple des agents chimiques et/ou biologiques.Such protective clothing is intended to protect the user wearing it, in particular when said user has to move around in an external environment vitiated by contaminating agents, such as for example chemical and/or biological agents.

Dans la suite de la description, on se place dans le cas où le vêtement de protection est une veste 10, comme illustré sur la figure 1. Néanmoins, l'invention peut également s'appliquer à tout vêtement de protection couvrant toute partie du corps de l'utilisateur, tel qu'un pantalon ou une combinaison.In the rest of the description, we consider the case where the protective garment is a jacket 10, as illustrated in the figure 1 . Nevertheless, the invention can also be applied to any protective clothing covering any part of the user's body, such as trousers or overalls.

La veste 10, comporte, dans son épaisseur, d'un environnement extérieur dans lequel évolue le corps de l'utilisateur le portant dans des conditions normales d'utilisation, vers ledit corps :

  • une première couche textile, dite couche externe 20,
  • une deuxième couche textile, dite couche de matériau filtrant 30, destinée à être en contact direct ou indirect avec le corps.
The jacket 10 comprises, in its thickness, from an external environment in which the body of the user wearing it evolves under normal conditions of use, towards said body:
  • a first textile layer, called outer layer 20,
  • a second textile layer, called layer of filtering material 30, intended to be in direct or indirect contact with the body.

Seule la couche externe 20 est visible sur la figure 1. La couche de matériau filtrant 30 est représentée en ligne pointillée sur la figure 2.Only the outer layer 20 is visible on the figure 1 . The layer of filter material 30 is shown in dotted line on the picture 2 .

La couche externe 20 et la couche de matériau filtrant 30 sont superposées et préférentiellement assemblées entre elles, par couture, uniquement sur le pourtour de la veste 10.The outer layer 20 and the layer of filtering material 30 are superimposed and preferably assembled together, by sewing, only around the periphery of the jacket 10.

La couche externe 20 est composée par un textile dont les fonctions principales sont :

  • d'une part, d'assurer la robustesse de la veste 10 par une protection contre les agressions mécaniques externes, notamment résistances à l'abrasion et à la déchirure, et
  • d'autre part de garantir la non-pénétration des agents contaminants sous forme liquide.
The outer layer 20 is composed of a textile whose main functions are:
  • on the one hand, to ensure the robustness of the jacket 10 by protection against external mechanical attack, in particular resistance to abrasion and tearing, and
  • on the other hand to guarantee the non-penetration of contaminating agents in liquid form.

La couche externe 20 présente également une perméabilité à l'air.The outer layer 20 also has air permeability.

La couche externe 20 est par exemple composée d'un textile tissé, non tissé ou tricoté, en fibres naturelles ou en fibres synthétiques.The outer layer 20 is for example composed of a woven, non-woven or knitted textile, in natural fibers or in synthetic fibers.

La couche externe 20 est par exemple constituée d'un tissu fin, par exemple un tissu en polyester, en polyamide, ou un mélange avec des fibres telles que par exemple du coton, de l'aramide ou de la viscose. Préférentiellement, la couche externe est constituée d'un mélange du type coton/polyester ou aramide/viscose.The outer layer 20 is for example made up of a thin fabric, for example a fabric made of polyester, polyamide, or a mixture with fibers such as for example cotton, aramid or viscose. Preferably, the outer layer consists of a mixture of the cotton/polyester or aramid/viscose type.

Pour garantir la non-pénétration des agents contaminants sous forme liquide, la couche externe présente avantageusement une double caractéristique hydrophobe et oléophobe.To guarantee the non-penetration of contaminants in liquid form, the outer layer advantageously has a dual hydrophobic and oleophobic characteristic.

Dans une forme de réalisation, cette double caractéristique hydrophobe et oléophobe est généralement obtenue par l'application, sur une face du textile, dite face externe, située du coté de l'environnement extérieur, d'un traitement hydrophobe et oléophobe, tel que par exemple un traitement à base de résines fluorocarbonées, telles que par exemple le Téflon®.In one embodiment, this dual hydrophobic and oleophobic characteristic is generally obtained by the application, on a face of the textile, called the external face, located on the side of the external environment, with a hydrophobic and oleophobic treatment, such as for example a treatment based on fluorocarbon resins, such as for example Teflon® .

La couche externe 20 présente, par exemple, une masse surfacique comprise entre 400 et 700 g/m2, plus précisément entre 150 et 250 g/m2, encore plus précisément de l'ordre de 200 g/m2.The outer layer 20 has, for example, a basis weight of between 400 and 700 g/m 2 , more precisely between 150 and 250 g/m 2 , even more precisely of the order of 200 g/m 2 .

La couche de matériau filtrant 30 est composée par un textile dont la fonction principale est d'assurer la filtration des agents contaminants sous forme vapeur. Cette filtration est généralement obtenue par un milieu adsorbant qui capture, par un phénomène d'adsorption ou de réaction, les agents contaminants sous forme vapeur.The layer of filtering material 30 is composed of a textile whose main function is to ensure the filtration of contaminants in vapor form. This filtration is generally obtained by an adsorbent medium which captures, by an adsorption or reaction phenomenon, the contaminating agents in vapor form.

Le milieu adsorbant est par exemple composé de charbons actifs, de zéolithes, de catalyseurs. Le milieu adsorbant est préférentiellement intégré dans le textile sous forme de poudre, de bille ou encore de fibres.The adsorbent medium is for example composed of activated carbons, zeolites, catalysts. The adsorbent medium is preferably integrated into the textile in the form of powder, ball or even fibers.

La couche de matériau filtrant 30 présente également une perméabilité à l'air.The layer of filter material 30 also has air permeability.

La couche de matériau filtrant 30 présente, par exemple, une masse surfacique comprise entre 60 et 450 g/m2, et plus précisément entre 200 et 350 g/m2.The layer of filtering material 30 has, for example, a surface mass of between 60 and 450 g/m 2 , and more precisely between 200 and 350 g/m 2 .

La couche de matériau filtrant peut être formée d'une seule pièce ou préférentiellement d'une pluralité d'empiècements assemblés par couture.The layer of filtering material can be formed in a single piece or preferably from a plurality of pieces assembled by sewing.

De manière préférentielle, la couche externe 20 de la veste 10 est formée d'une pluralité d'empiècements 21, 22, 23, 24, assemblés entre eux, notamment deux à deux, par couture.Preferably, the outer layer 20 of the jacket 10 is formed of a plurality of yokes 21, 22, 23, 24, assembled together, in particular two by two, by sewing.

La couche externe 20 de la veste 10 de protection comporte, de manière non limitative :

  • une partie ventrale 21, destinée à être disposée à l'avant du corps d'un utilisateur, c'est-à-dire au niveau de son torse,
  • une partie dorsale 22 opposée, destinée à être disposée au niveau du dos dudit utilisateur,
  • deux manches 23, destinées à être disposées chacune au niveau d'un bras de l'utilisateur.
The outer layer 20 of the protective jacket 10 comprises, in a non-limiting manner:
  • a ventral part 21, intended to be arranged at the front of a user's body, that is to say at the level of his torso,
  • an opposite dorsal part 22, intended to be placed at the level of the back of said user,
  • two sleeves 23, each intended to be arranged at the level of one arm of the user.

Elle peut également comporter une capuche 24, destinée à être disposée au niveau de la tête de l'utilisateur, recouvrant la tête hormis le visage, comme illustré sur la figure 1.It may also include a hood 24, intended to be placed at the level of the user's head, covering the head apart from the face, as illustrated in the figure 1 .

La partie ventrale 21 et la partie dorsale 22 sont assemblées entre elles au niveau des zones d'épaules et des flancs de l'utilisateur. Elles sont assemblées également aux deux manches 23 et à la capuche 24, si la veste en comporte une.The ventral part 21 and the dorsal part 22 are assembled together at the level of the user's shoulder zones and flanks. They are also assembled to the two sleeves 23 and to the hood 24, if the jacket has one.

Avantageusement, pour permettre à l'utilisateur d'enfiler et de retirer la veste de protection aisément, la partie ventrale 21 peut être formée de deux parties assemblées entre elles par exemple par une fermeture à glissière.Advantageously, to allow the user to put on and take off the protective jacket easily, the ventral part 21 can be formed of two parts assembled together, for example by a zipper.

Pour compléter la veste, les parties ventrale 21, dorsale 22 manches 23 et ou capuche 24 peuvent comporter chacune, une pièce additionnelle assemblée par couture à la couche externe 20.To complete the jacket, the ventral 21, dorsal 22, sleeve 23 and or hood 24 parts can each include an additional piece assembled by sewing to the outer layer 20.

Par pièces additionnelles, on entend des pièces qui viennent se rajouter sur la veste, telles que par exemple des poches 25 ou des renforts 26. Ces pièces additionnelles sont assemblées à la couche externe, elles ne forment pas en tant que telles la couche externe 20 de la veste.By additional parts, we mean parts that are added to the jacket, such as for example pockets 25 or reinforcements 26. These additional parts are assembled to the outer layer, they do not as such form the outer layer 20 of the jacket.

Dans un exemple de réalisation, les parties ventrale 21, dorsale 22 manches 23 et ou capuche 24 peuvent comporter au moins une poche 25 ou un renfort 26, tel qu'un renfort de coude, assemblés au niveau de la face externe de la couche externe 20. Seuls une poche 25 sur la partie ventrale 21 et un renfort 26 au coude sur une des manches 23 sont représentés sur la figure 1.In an exemplary embodiment, the ventral 21, dorsal 22, sleeve 23 and or hood 24 parts may include at least one pocket 25 or a reinforcement 26, such as an elbow reinforcement, assembled at the level of the external face of the external layer. 20. Only a pocket 25 on the ventral part 21 and a reinforcement 26 at the elbow on one of the sleeves 23 are represented on the figure 1 .

Les empiècements formant la couche externe 20, que ce soient la partie ventrale 21, la partie dorsale 22, les manches 23, la capuche 24, ainsi que les pièces additionnelles, c'est-à-dire poches 25, renforts 26 ou autres, sont assemblés entre eux par couture au niveau de zones dites d'assemblage.The inserts forming the outer layer 20, whether the ventral part 21, the back part 22, the sleeves 23, the hood 24, as well as the additional parts, that is to say pockets 25, reinforcements 26 or others, are assembled together by sewing at so-called assembly zones.

Selon l'assemblage à réaliser, empiècement/empiècement ou empiècement/pièce additionnelle, les coutures peuvent être différentes.Depending on the assembly to be made, yoke/yoke or yoke/additional piece, the seams may be different.

Dans une première forme de réalisation d'une couture, ladite couture est une couture dite d'assemblage.In a first embodiment of a seam, said seam is a so-called assembly seam.

Par couture d'assemblage, on entend une couture adaptée pour l'assemblage d'un empiècement avec un autre empiècement.By assembly seam is meant a seam suitable for the assembly of a yoke with another yoke.

La partie ventrale 21 et la partie dorsale 22 sont ainsi assemblées entre elles par une couture d'assemblage au niveau des zones d'épaules et des flancs de l'utilisateur. Elles sont assemblées séparément aux deux manches 23. Elles sont également assemblées à la capuche 24.The ventral part 21 and the dorsal part 22 are thus assembled together by an assembly seam at the level of the user's shoulder zones and flanks. They are assembled separately to the two sleeves 23. They are also assembled to the hood 24.

La figure 2 illustre des variantes (a) et (b), (h), (i) de couture d'assemblage.The picture 2 illustrates variants (a) and (b), (h), (i) of assembly stitching.

Les variantes (a), (h), (i) représentent une couture de type rabattue double aiguille.Variants (a), (h), (i) represent a double-needle, hemstitch type seam.

La variante (b) représente une couture de type surjet cinq fils.Variation (b) represents a five-thread overlock type seam.

La figure 1 illustre par exemple la localisation des variantes (a) et (b) de coutures d'assemblage.The figure 1 illustrates for example the location of variants (a) and (b) of assembly seams.

Chaque couture d'assemblage est configurée afin que chaque fil de couture traverse au moins une épaisseur de chaque empiècement de part en part.Each assembly seam is configured so that each sewing thread passes through at least one thickness of each yoke right through.

Dans une deuxième forme de réalisation d'une couture, ladite couture est une couture dite de fixation.In a second embodiment of a seam, said seam is a so-called fastening seam.

Par couture de fixation, on entend une couture adaptée pour l'assemblage d'une pièce additionnelle sur un empiècement.By fastening seam is meant a seam suitable for the assembly of an additional piece on a yoke.

Les poches 25 sont ainsi assemblées soit à la partie ventrale 21, partie dorsale 22, manche 23, ou capuche 24, par une couture de fixation. De même, les renforts 26 sont assemblés soit à la partie ventrale 21, partie dorsale 22, manche 23, ou capuche 24, par une couture de fixation.The pockets 25 are thus assembled either to the ventral part 21, back part 22, sleeve 23, or hood 24, by an attachment seam. Similarly, the reinforcements 26 are assembled either to the ventral part 21, back part 22, sleeve 23, or hood 24, by an attachment seam.

La figure 2 illustre deux variantes (e) et (g) de couture de fixation :

  • La variante (e) est une couture de fixation de type couture à points noués par exemple destinée à la pose de poche ou de renfort,
  • La variante (g) est une couture de fixation de type couture à points noués par exemple destinée au rabat de poche,
  • La figure 2 illustre également une variante (d) qui est une couture de fixation de type couture à points noués renforcée par une bride, par exemple destinée aux coins de poche. Cette bride permet de renforcer une couture de fixation qui est très sollicitée mécaniquement, telle que par exemple les coins de poche, et réduire le risque de casse du fil de couture de manière prématurée.
The picture 2 illustrates two variants (e) and (g) of fastening seam:
  • Variant (e) is a fastening seam of the lockstitch type, for example intended for laying pockets or reinforcements,
  • Variant (g) is a fastening seam of the lockstitch type, for example intended for the pocket flap,
  • The picture 2 also illustrates a variant (d) which is a fastening seam of the lockstitch type reinforced with a flange, for example intended for pocket corners. This flange makes it possible to reinforce a fastening seam which is very stressed mechanically, such as for example the corners of pockets, and to reduce the risk of premature breakage of the sewing thread.

La figure 1 illustre la localisation de ces variantes (d), (e) et (g) de coutures de fixation.The figure 1 illustrates the location of these variants (d), (e) and (g) of fastening seams.

Chaque couture de fixation est configurée afin que chaque fil de couture traverse au moins une épaisseur de la pièce additionnelle et un empiècement de part en part.Each fastening seam is configured so that each sewing thread passes through at least one thickness of the additional part and one yoke right through.

Que ce soit pour la couture d'assemblage ou la couture de fixation, le fil de couture utilisé est un fil de couture classique, ayant ou non subi un traitement hydrophobe et oléophobe.Whether for the assembly seam or the fastening seam, the sewing thread used is a conventional sewing thread, which may or may not have undergone a hydrophobic and oleophobic treatment.

Pour améliorer la protection de la veste contre la pénétration des agents contaminants au niveau des coutures, la veste 10 comporte, au moins au niveau d'une zone d'assemblage, de préférence toutes les zones d'assemblage, une troisième couche textile, dite couche de renfort 40.To improve the protection of the jacket against the penetration of contaminants at the seams, the jacket 10 comprises, at least at the level of an assembly zone, preferably all the assembly zones, a third textile layer, called reinforcement layer 40.

Cette couche de renfort peut soit être disposée uniquement au niveau des zones d'assemblage soit recouvrir l'ensemble de la surface de la veste. Dans ce cas, ladite couche de renfort se superpose à la couche externe et à la couche de matériau filtrant, formant un doublage intégral de la veste.This reinforcement layer can either be placed only at the assembly zones or cover the entire surface of the jacket. In this case, said reinforcement layer is superimposed on the outer layer and on the layer of filtering material, forming an integral lining of the jacket.

La couche de renfort 40 est composée d'un textile présentant une double caractéristique hydrophile et oléophile. La couche de renfort 40 a pour fonction principale d'absorber l'agent contaminant sous forme liquide qui a traversé la couche externe par les perforations de la couture et qui a été guidé par le fil de couture vers la couche de renfort.The reinforcement layer 40 is composed of a textile having a double hydrophilic and oleophilic characteristic. The main function of the reinforcement layer 40 is to absorb the contaminant in liquid form which has passed through the outer layer through the perforations of the seam and which has been guided by the sewing thread towards the reinforcement layer.

La couche de renfort 40 présente également une perméabilité à l'air.The reinforcement layer 40 also has air permeability.

La couche de renfort est composée d'un textile, par exemple un textile tissé, non tissé ou tricoté, en fibres naturelles et/ou en fibres synthétiques.The reinforcing layer is composed of a textile, for example a woven, non-woven or knitted textile, made of natural fibers and/or of synthetic fibers.

La couche de renfort est par exemple constituée d'un tissu fin, par exemple un tissu en polyester, en polyamide, purs ou un mélange avec des fibres telles que par exemple du coton ou de la viscose.The reinforcing layer is for example made up of a fine fabric, for example a fabric made of polyester, of polyamide, pure or a mixture with fibers such as for example cotton or viscose.

La couche de renfort 40 présente avantageusement une double caractéristique hydrophile et oléophile.The reinforcing layer 40 advantageously has a dual hydrophilic and oleophilic characteristic.

Dans une forme de réalisation, cette double caractéristique hydrophile et oléophile est obtenue de part la nature même des fibres composant le textile, qui sont hydrophiles et oléophiles.In one embodiment, this dual hydrophilic and oleophilic characteristic is obtained by the very nature of the fibers making up the textile, which are hydrophilic and oleophilic.

Dans un exemple de réalisation, la couche de renfort est composée d'un mélange polyester/polyamide (70/30).In an exemplary embodiment, the reinforcing layer is composed of a polyester/polyamide (70/30) blend.

Dans une autre forme de réalisation, cette double caractéristique hydrophile et oléophile est généralement obtenue par l'application d'un traitement hydrophile et oléophile.In another embodiment, this dual hydrophilic and oleophilic characteristic is generally obtained by the application of a hydrophilic and oleophilic treatment.

Dans la zone d'assemblage, la couche de renfort 40 est directement assemblée à la couche externe, soit par la couture d'assemblage soit la couture de fixation.In the assembly zone, the reinforcement layer 40 is directly assembled to the outer layer, either by the assembly seam or the fastening seam.

Préférentiellement, la couche de renfort 40 est assemblée uniquement à la couche externe.Preferably, the reinforcement layer 40 is assembled only to the outer layer.

Dans le cas où la couture est une couture d'assemblage, la couche de renfort est insérée de façon telle que chaque fil de couture traverse systématiquement au moins une épaisseur de chaque empiècement de la couche externe et au moins une épaisseur de la couche de renfort de part en part. La couche de renfort est assemblée aux deux empiècements de la couche externe par la couture qui assemble lesdits deux empiècements.In the case where the seam is an assembly seam, the reinforcement layer is inserted in such a way that each sewing thread systematically passes through at least one thickness of each yoke of the outer layer and at least one thickness of the reinforcement layer from side to side. The reinforcement layer is joined to the two yokes of the outer layer by the seam which joins said two yokes.

Dans le cas où la couture est une couture de fixation, la couche de renfort est insérée de façon telle que chaque fil de couture traverse systématiquement au moins une épaisseur de la pièce additionnelle, au moins une épaisseur de l'empiècement de la couche externe et au moins une épaisseur de la couche de renfort de part en part. La couche de renfort est assemblée à la pièce additionnelle et à l'empiècement de la couche externe par la couture qui assemble ladite pièce additionnelle et ledit empiècement de la couche externe.In the case where the seam is a fastening seam, the reinforcement layer is inserted in such a way that each sewing thread systematically passes through at least one thickness of the additional piece, at least one thickness of the yoke of the outer layer and at least one thickness of the reinforcing layer right through. The reinforcement layer is assembled to the additional piece and to the yoke of the outer layer by the seam which assembles said additional piece and said yoke of the outer layer.

Dans un mode de réalisation, quelque soit la forme de réalisation de la couture, la couche de renfort est comprise entre les deux empiècements ou entre un empiècement et une pièce rapportée, comme illustré sur la figure 2 pour les variantes (b), (d).In one embodiment, whatever the embodiment of the seam, the reinforcement layer is between the two yokes or between a yoke and an added piece, as illustrated in the picture 2 for variants (b), (d).

Dans un autre mode de réalisation, pour simplifier les opérations de confection de la couche externe, quelque soit la forme de réalisation de la couture, la couche de renfort est placée contre un seul empiècement, du coté de la couche de matériau filtrant, comme illustré sur la figure 2 pour les variantes (a), (c), (f).In another embodiment, to simplify the operations of making the outer layer, whatever the embodiment of the seam, the reinforcement layer is placed against a single yoke, on the side of the layer of filter material, as shown on the figure 2 for variants (a), (c), (f).

La description ci-avant expose de manière détaillée un vêtement de protection sous la forme d'une veste. Dans une autre forme de réalisation du vêtement de protection, illustrée figure 3, le vêtement de protection est un pantalon 90. La figure 3 illustre la location des variantes (a) à (g) des coutures d'assemblage et de fixation sur ledit pantalon.The above description sets out in detail a protective garment in the form of a jacket. In another embodiment of the protective garment, illustrated picture 3 , the protective clothing is 90 pants. picture 3 illustrates the location of variants (a) to (g) of the assembly and fastening seams on said pants.

Afin d'illustrer les améliorations significatives obtenues par l'ajout de la couche de renfort au vêtement, qu'il soit une veste, un pantalon ou autre, de nombreuses expériences ont été réalisées et sont synthétisées ci-dessous sous la forme de trois exemples non limitatifs.In order to illustrate the significant improvements obtained by adding the reinforcement layer to the garment, whether it is a jacket, pants or other, numerous experiments have been carried out and are summarized below in the form of three examples. not limiting.

Pour toutes les expériences :

  • la couche externe est un tissu en coton/polyester (65%/35%) de 190 g/m2 ayant reçu un traitement fluoro-carboné lui conférant une caractéristique hydrophobe (Niveau 5 selon la norme française NF EN ISO 4920) et oléophobe (Niveau 5 selon la norme NF EN ISO 14419),
  • la couche de matériau filtrant est une mousse polyuréthane imprégnée de 100 g/m2 de charbon actif,
  • aucune couture n'assemble la couche externe et la couche de matériau filtrant.
For all experiments:
  • the outer layer is a 190 g/m 2 cotton/polyester fabric (65%/35%) having received a fluoro-carbon treatment giving it a hydrophobic (Level 5 according to French standard NF EN ISO 4920) and oleophobic ( Level 5 according to standard NF EN ISO 14419),
  • the layer of filtering material is a polyurethane foam impregnated with 100 g/m 2 of activated carbon,
  • no seams join the outer layer and the layer of filter material.

De même, pour toutes les expériences, la caractérisation de la performance d'un vêtement de protection est réalisée par prélèvement d'un échantillon des couches constitutives du vêtement de protection et contamination par dépôt de gouttes d'agents contaminants sur la face externe de la couche externe du vêtement. Chaque essai est d'une durée de 24 heures, durant lesquelles la quantité d'agent contaminant ayant traversé les couches est recueillie, quantifiée puis exprimée en µg/cm2. Plus la quantité d'agent contaminant est élevée, plus la protection apportée est jugée faible.Similarly, for all the experiments, the characterization of the performance of protective clothing is carried out by sampling a sample of the layers that make up the protective clothing and contamination by depositing drops of contaminants on the outer face of the outer layer of the clothing. Each test lasts 24 hours, during which the quantity of contaminant having passed through the layers is collected, quantified and then expressed in µg/cm 2 . The higher the quantity of contaminant, the lower the protection provided.

Les expériences sont réalisées avec un banc d'essai, adapté et configuré à des tels tests, et dont la limite basse de détection d'agent contaminant est de 0.08 µg/cm2. On peut ainsi considérer que toute pénétration d'agent contaminant inférieure à cette limite basse de détection correspond à une protection totale.The experiments are carried out with a test bench, adapted and configured for such tests, and whose low detection limit for contaminating agent is 0.08 µg/cm 2 . It can thus be considered that any contaminant penetration below this low detection limit corresponds to total protection.

L'évaluation des performances du vêtement de protection a été réalisée selon un protocole de contamination avec un agent contaminant de type Ypérite, déposé sous forme de goutte de 1 µl jusqu'à obtention d'un niveau de contamination de 10 g/m2. Une aspiration d'air au travers de l'échantillon à un débit de 100 ml/min est ensuite réalisée afin de garantir la collecte des vapeurs d'Ypérite ayant traversé les différentes couches de l'échantillon. Le taux de pénétration d'Ypérite est exprimé après 24 heures en µg/cm2.The performance evaluation of the protective clothing was carried out according to a contamination protocol with a contaminant of Yperite type, deposited in the form of a 1 μl drop until a contamination level of 10 g/m 2 was obtained. Air suction through the sample at a flow rate of 100 ml/min is then carried out in order to guarantee the collection of mustard gas vapors having passed through the different layers of the sample. Mustard penetration rate is expressed after 24 hours in µg/cm 2 .

Exemple 1Example 1

Dans ce premier exemple, des essais ont été réalisés sur trois types d'échantillons ne comportant pas de couche de renfort, c'est-à-dire uniquement un empilement couche externe et couche de matériau filtrant (représentatif des vêtements de protection existants) :

  • un premier échantillon non pourvu de coutures,
  • un deuxième échantillon pourvu d'une couture d'assemblage dans la couche externe, de type rabattue double aiguille, comme illustré sur la figure 4, avec un fil polyester non traité, le fil présentant un poids de 0,45 g/ml (gramme par mètre linéaire),
  • un troisième échantillon pourvu d'une couture d'assemblage dans la couche externe, également de type rabattue double aiguille, avec un fil ayant reçu un traitement fluoro-carboné lui conférant une double caractéristique hydrophobe et oléophobe, le fil présentant un poids de 0,52 g/ml.
In this first example, tests were carried out on three types of samples with no reinforcement layer, i.e. only a stack of outer layer and layer of filtering material (representative of existing protective clothing):
  • a first sample without seams,
  • a second sample provided with a joining seam in the outer layer, of the double-needle turn-down type, as illustrated in the figure 4 , with an untreated polyester yarn, the yarn having a weight of 0.45 g/ml (gram per linear meter),
  • a third sample provided with an assembly seam in the outer layer, also of the double-needle folded type, with a yarn having received a fluoro-carbon treatment giving it a dual hydrophobic and oleophobic characteristic, the yarn having a weight of 0.52 g/ml.

Les résultats sont résumés dans le tableau ci-dessous : Sans couture Couture avec un fil non traité Couture avec un fil fluoro-carboné Pénétration en µg/cm2 <0.08 ±0.00 3.55±3.40 4.46±5.88 The results are summarized in the table below: Seamless Sewing with untreated thread Sewing with a fluoro-carbon thread Penetration in µg/cm 2 <0.08 ±0.00 3.55±3.40 4.46±5.88

On constate effectivement le phénomène de vulnérabilité aux coutures.There is indeed the phenomenon of vulnerability at the seams.

Une pénétration d'agent contaminant inférieure à la limite basse de détection est obtenue dans le premier échantillon. Par contre, une pénétration d'agent contaminant supérieure à la limite basse de détection est obtenue pour les deuxième et troisième échantillons, ceux pourvus d'une couture.A contaminant penetration below the lower detection limit is obtained in the first sample. On the other hand, a contaminant penetration greater than the lower detection limit is obtained for the second and third samples, those provided with a seam.

L'emploi d'un fil traité fluoro-carboné n'apporte aucunement d'amélioration de la protection du vêtement de protection contre les agents contaminants.The use of a fluoro-carbon treated yarn does not provide any improvement in the protection of the protective clothing against contaminants.

Exemple 2Example 2

Dans ce deuxième exemple, des essais ont été réalisé sur deux types d'échantillons pourvus d'une couture dans la couche externe :

  • un premier échantillon :
    • o avec une couche de renfort sous la forme d'un non-tissé composé d'un mélange polyamide/polyester (70/30) d'un grammage de 60 g/m2 lui conférant par nature une double caractéristique hydrophile et oléophile, ci-après dénommée couche de renfort A, et
    • ∘ pourvu d'une couture dans la couche externe, de type rabattue double aiguille, comme illustré sur la figure 4, avec un fil polyester non traité, le fil présentant un poids de 0,45 g/ml,
    • ∘ la couche de renfort a été insérée dans la couture, comme illustré sur la variante (a) de la figure 2, permettant à tous les fils de couture de traverser systématiquement les deux épaisseurs de chaque empiècement de la couche externe et la couche de renfort,
  • un deuxième échantillon :
    • ∘ avec une couche de renfort sous la forme d'un non-tissé composé d'un mélange polyamide/polyester (70/30) d'un grammage de 60 g/m2 ayant reçu un traitement fluoro-carboné lui conférant ainsi une caractéristique hydrophobe (Niveau 5 selon la norme française NF EN ISO 4920) et oléophobe (Niveau 5 selon la norme NF EN ISO 14419), ci-après dénommée couche de renfort B,
    • ∘ pourvu d'une couture dans la couche externe, de type rabattue double aiguille, comme illustré sur la figure 4, avec un fil polyester non traité, le fil présentant un poids de 0,45 g/ml,
    • ∘ la couche de renfort a été insérée dans la couture, comme illustré sur la variante (a) de la figure 2, permettant à tous les fils de couture de traverser systématiquement les deux empiècements de la couche externe et la couche de renfort.
In this second example, tests were carried out on two types of samples provided with a seam in the outer layer:
  • a first sample:
    • o with a reinforcing layer in the form of a nonwoven composed of a polyamide/polyester (70/30) mixture with a weight of 60 g/m 2 giving it by nature a dual hydrophilic and oleophilic characteristic, ci - after referred to as reinforcing layer A, and
    • ∘ provided with a seam in the outer layer, double-needle turn-down type, as illustrated in the figure 4 , with an untreated polyester yarn, the yarn having a weight of 0.45 g/ml,
    • ∘ the reinforcement layer has been inserted into the seam, as shown in variant (a) of the picture 2 , allowing all the sewing threads to systematically cross the two thicknesses of each yoke of the outer layer and the reinforcement layer,
  • a second sample:
    • ∘ with a reinforcement layer in the form of a non-woven made up of a polyamide/polyester (70/30) blend with a weight of 60 g/m 2 having received a fluoro-carbon treatment thus giving it a hydrophobic (Level 5 according to French standard NF EN ISO 4920) and oleophobic (Level 5 according to standard NF EN ISO 14419), hereinafter referred to as reinforcement layer B,
    • ∘ provided with a seam in the outer layer, double-needle turn-down type, as illustrated in the figure 4 , with an untreated polyester yarn, the yarn having a weight of 0.45 g/ml,
    • ∘ the reinforcement layer has been inserted into the seam, as shown in variant (a) of the picture 2 , allowing all the sewing threads to systematically pass through the two yokes of the outer layer and the reinforcement layer.

Les résultats sont résumés dans le tableau ci-après : Couture avec couche de renfort A Couture avec couche de renfort B Pénétration en µg/cm2 <0.08±0.00 11.12±4.00 The results are summarized in the table below: Seam with reinforcement layer A Seam with reinforcement layer B Penetration in µg/cm 2 <0.08±0.00 11.12±4.00

On constate qu'une pénétration d'agent contaminant supérieure à la limite basse de détection est obtenue pour le deuxième échantillon. Contrairement aux enseignements donnés dans l'état de l'art qui conduiraient à employer préférentiellement un couche de renfort présentant une double caractéristique hydrophobe et oléophobe pour consolider la protection contre la pénétration des agents contaminants sous forme liquide, l'utilisation de la couche de renfort B provoque une nette augmentation de la pénétration des agents contaminants. La couche de renfort B semble favoriser le transfert vers la couche de matériau filtrant, probablement par répulsion de la phase liquide de l'agent contaminant ayant pénétré par le fil de couture vers la couche de matériau filtrant.It can be seen that a contaminant penetration greater than the lower detection limit is obtained for the second sample. Contrary to the teachings given in the state of the art which would lead to the preferential use of a reinforcing layer having a dual hydrophobic and oleophobic characteristic to consolidate the protection against the penetration of contaminants in liquid form, the use of the reinforcing layer B causes a marked increase in the penetration of contaminants. The reinforcement layer B seems to favor the transfer towards the layer of filtering material, probably by repulsion of the liquid phase of the contaminant having penetrated by the sewing thread towards the layer of filtering material.

Au contraire, et de manière surprenante, aucune pénétration d'agent contaminant n'est décelée dans le premier échantillon. La couche de renfort A absorbe et localise l'agent contaminant dans la couche externe et lui interdit l'accès à la couche de matériau filtrant.On the contrary, and surprisingly, no contaminant penetration is detected in the first sample. The reinforcement layer A absorbs and localizes the contaminant in the outer layer and prevents it from accessing the layer of filtering material.

Exemple 3Example 3

Dans ce troisième exemple, des essais ont été réalisés avec différentes variantes de couture dans la couche externe, au total sept variantes de couture. Ces essais ont été réalisés avec une couche de renfort A, et avec un fil polyester non traité, le fil présentant un poids de 0,45 g/ml.In this third example, tests were carried out with different seam variants in the outer layer, a total of seven seam variants. These tests were carried out with a reinforcing layer A, and with an untreated polyester yarn, the yarn having a weight of 0.45 g/ml.

Les sept variantes de couture testées représentent l'intégralité des assemblages par couture d'un vêtement de protection NRBC existant. Chaque assemblage a été adapté afin que chaque fil de couture traversant la couche externe de part en part traverse également une couche de renfort, et sans traverser la couche de matériau filtrant.The seven seam variants tested represent all of the seam assemblies of an existing CBRN protective garment. Each assembly has been adapted so that each sewing thread crossing the outer layer right through also crosses a reinforcement layer, and without crossing the layer of filtering material.

Les essais ont été réalisés avec les 7 variantes (a) à (g) illustrées sur la figure 2.The tests were carried out with the 7 variants (a) to (g) illustrated on the picture 2 .

Pour rappel, les coutures (a), (b), (c), sont destinées aux coutures d'assemblage, et les coutures (d), (e), (f) et 'g) sont destinées aux coutures de fixation. Plus particulièrement, les coutures (e), (f) sont destinées à la pose de renforts ou de poches, la couture (g) au rabat de poches et la couture (d) aux brides de renfort.As a reminder, seams (a), (b), (c), are intended for assembly seams, and seams (d), (e), (f) and 'g) are intended for attachment seams. More specifically, the seams (e), (f) are intended for laying reinforcements or pockets, the seam (g) to the pocket flap and the seam (d) to the reinforcement straps.

Les résultats sont résumés dans le tableau ci-dessous : Type de couture (a) (b) (c) (d) (e) (f) (g) Pénétration en µg/cm2 <0.08 <0.08 <0.08 <0.08 <0.08 <0.08 <0.08 The results are summarized in the table below: type of seam (has) (b) (vs) (d) (e) (g) (g) Penetration in µg/cm 2 <0.08 <0.08 <0.08 <0.08 <0.08 <0.08 <0.08

On constate que, quelque soit la variante de couture testée, les essais sont tous concluants et qu'aucune pénétration d'agent contaminant n'est décelée.It can be seen that, whatever the seam variant tested, the tests are all conclusive and that no penetration of contaminant is detected.

La description ci-avant illustre clairement que par ses différentes caractéristiques et leurs avantages, la présente invention atteint les objectifs qu'elle s'était fixés. En particulier, elle fournit un vêtement de protection qui permet de renforcer, notamment au niveau des coutures, le vêtement de protection contre les effets des agents contaminants sous toutes ses formes, que ce soit sous forme liquide ou sous forme vapeur, tout en conservant le confort du vêtement pour l'utilisateur.The above description clearly illustrates that through its various characteristics and their advantages, the present invention achieves the objectives it had set itself. In particular, it provides protective clothing which makes it possible to reinforce, in particular at the seams, the protective clothing against the effects of contaminants in all their forms, whether in liquid form or in vapor form, while retaining the wearer comfort.
