Description

Il existe des vêtements de protection dits NBCF, c'est à-dire destinés à protéger des effets des retombées de poussieres radio-actives après une explosion nucléaire, ainsi que des effets corrosifs, toxiques ou autres des substances biologiques (batte riologiques notamment) et chimiques, et à protéger enfin contre le feu. There are protective clothing known as NBCF, that is to say intended to protect from the effects of fallout of radioactive dust after a nuclear explosion, as well as from the corrosive, toxic or other effects of biological substances (in particular biological bat) and chemical, and finally protect against fire.

La présente invention a pour objet un tel vetement d'une conception nouvelle par la nature des matières qui le constituent. The present invention relates to such a garment of a new design by the nature of the materials which constitute it.

Ce vêtement est caractérisé en ce qu'il comprend une couche extérieure de tissu ignifuge, en fibres mixtes d'un polyamide -imide ininflammable et thermostable et d'une viscose ignifugée, et une couche intérieure formant doublure, fixe ou amovible, en mousse de polyuréthane imprégnée de charbon actif. This garment is characterized in that it comprises an outer layer of flame-retardant fabric, made of mixed fibers of a non-flammable and thermostable polyamide-imide and of a flame-retardant viscose, and an inner layer forming a lining, fixed or removable, of polyurethane impregnated with activated carbon.

le tissu de la couche extérieure peut être un tissu tissé, un tissu tricoté ou un non-tissé. les fibres en polyamideimide ininflammable et thermostable peuvent être les fibres de la marque "Kermel" fabriquées par la Société française Rh8ne-Poulene-
Textile et appartenant à la famille chimique de formule générale

Figure img00010001

ces fibres sont colorées dans la masse. Elles peuvent etre les fibres de la marque ',Nomex" fabriquées par la Société américaine Dupont de Nemours. Les fibres de viscose ignifugée peuvent entre celles de la marque 1,Viscose IF 80" fabriquées par la Societé française Rhône-Poulenc-Textile et à ignifugation permanente par une incorporation pigmentaire dans la masse.Les précédents exem ples ne sont aucunement limitatifs.the fabric of the outer layer may be a woven fabric, a knitted fabric or a nonwoven. the non-flammable and thermostable polyamideimide fibers may be the fibers of the brand "Kermel" manufactured by the French company Rh8ne-Poulene-
Textile and belonging to the chemical family of general formula
Figure img00010001

these fibers are colored in the mass. They can be the fibers of the brand, Nomex "manufactured by the American company Dupont de Nemours. The flame-retardant viscose fibers can between those of brand 1, Viscose IF 80" manufactured by the French company Rhône-Poulenc-Textile and permanent fireproofing by pigmentary incorporation into the mass. The preceding examples are in no way limiting.

Un tissu tout-à-fait convenable pour la couche extérieure est un tissu mixte Eermel-Viscose IF 80 comprenant 50 en poids de chacune des deux fibres; les deux sortes de fibres sont mélangées en bourre au moment de la fabrication du filé. Avec ce filé, on peut réaliser un satin ou une serge de 250 g/m environ ou un chevron sur base de sergé de 205 g/m2. Tous les tissus en Kermel-Viscose IF 80 ont des propriétés spécifiquement NBC et assurent en outre une protection permanente élevée contre la chaleur et contre le feu, étant incombustibles. De plus, ils offrent une antistaticité permanente et une reprise d'humidité élevée assurant un grand confort, du fait de la présence de la viscose, une bonne résistance aux acides concentrés à chaud et une permanence du coloris, les fibres constitutives de ces tissus étant colorées dans la masse.Ces tissus ont aussi les résistances mécaniques élevées, qui caractérisent les fibres de Kermel. A fabric completely suitable for the outer layer is a mixed Eermel-Viscose IF 80 fabric comprising 50 by weight of each of the two fibers; the two kinds of fibers are mixed in fluff when the yarn is made. With this yarn, you can make a satin or twill of around 250 g / m or a chevron on the basis of twill of 205 g / m2. All fabrics in Kermel-Viscose IF 80 have NBC specific properties and also provide high permanent protection against heat and fire, being non-combustible. In addition, they offer a permanent antistaticity and a high humidity recovery ensuring great comfort, due to the presence of viscose, good resistance to hot concentrated acids and permanence of the color, the constituent fibers of these fabrics being colored in the mass. These fabrics also have the high mechanical strengths, which characterize Kermel fibers.

la couche intérieure ou doublure, qui est en mousse de polyuréthane imprégnée de charbon actif, isole de la chaleur et du feu et a des propriétés filtrantes; elle résiste à une contamination chimique allant de 6h à plusieurs semaines suivant les conditions d'emploi; le charbon actif absorbe et anéantit les substances toxiques ou corrosives. the inner layer or lining, which is made of polyurethane foam impregnated with activated carbon, insulates from heat and fire and has filtering properties; it resists chemical contamination ranging from 6 hours to several weeks depending on the conditions of use; activated carbon absorbs and destroys toxic or corrosive substances.

la mousse de polyuréthane est de préférence contrecollée sur un tissu à mailles, par exemple un jersey, de préfé rence en coton, mais pouvant aussi être en fibres synthétiques, par exemple en polyamide ou en polyester. Ce jersey, destiné à etre en contact avec la peau de l'utilisateur, rend le vêtement plus confortable. La mousse de polyuréthane et le tissu à mailles ont avantageusement été traités de façon à être ignifuges et auto extinguibles. the polyurethane foam is preferably laminated to a mesh fabric, for example a jersey, preferably cotton, but can also be made of synthetic fibers, for example polyamide or polyester. This jersey, intended to be in contact with the user's skin, makes the garment more comfortable. The polyurethane foam and the mesh fabric have advantageously been treated so as to be flame retardant and self-extinguishing.

Le poids et l'armure du tissu de la couche extérieure ainsi que l'épaisseur de la mousse carbonée de la doublure peuvent varier en fonction des conditions d'utilisation.The weight and weave of the fabric of the outer layer as well as the thickness of the carbon foam of the lining may vary depending on the conditions of use.

le vêtement suivant l'invention, à la fois ignifuge et
NBC, a été conçu pour la protection du personnel soumis à des risques d'agression par la chaleur et le feu ainsi qu'à des ris quesde contaminations nucléaire, biologique et chimique (combattants, pilotes d'avion, équipages d'engins blindés, équipes de sécurité, équipes de secours, pompiers, personnel de l'industrie, etc...).the garment according to the invention, both flame retardant and
NBC, was designed for the protection of personnel subjected to risks of aggression by heat and fire as well as to risks of nuclear, biological and chemical contamination (combatants, airplane pilots, crews of armored vehicles, security teams, rescue teams, firefighters, industry personnel, etc.).

Ce vêtement peut se présenter sous forme d'une combinaison ou sous forme d'un ensemble veste-pantalon. La superposition du tissu extérieur et de la doublure filtrante constitue un complexe perméable à l'air, mais imperméable aux poussières, liquides et vapeurs toxiques et agressifs. le vêtement comporte une cagoule attenante, qui s'adapte sur un masque à gaz. La protection des mains et des pieds est assurée par des gants, sous-gants et chaussettes NBC. This garment can be in the form of a jumpsuit or in the form of a jacket-pants set. The superimposition of the outer fabric and the filter lining constitutes an air-permeable complex, but impermeable to toxic and aggressive dust, liquids and vapors. the garment has an attached hood, which fits over a gas mask. Hand and foot protection is provided by NBC gloves, under-gloves and socks.

En ce qui concerne la protection contre la contamination chimique, il convient de faire observer que le tissu de la couche extérieure a un excellent.pouvoir déperlant, c'est-à-dire un pouvoir de transformation des liquides en gouttelettes qui glissent sur le tissu; autrement dit, les gouttes de liquide toxique ne s'y accrochent pas. De plus, le tissu de la couche extérieure est hermétique aux aérosols; les vapeurs de produits toxiques qui pourraient le traverser sont absorbées par le charbon actif de la mousse de polyuréthane carbonée. With regard to protection against chemical contamination, it should be noted that the fabric of the outer layer has an excellent water repellency, that is to say a power to transform liquids into droplets which slide on the fabric ; in other words, the drops of toxic liquid do not cling to it. In addition, the fabric of the outer layer is airtight; the vapors of toxic products which could pass through it are absorbed by the activated carbon of the carbonated polyurethane foam.

Après une contamination par des substances liquides toxiques, le vêtement doit être nettoyé et la doublure filtrante doit être remplacée. A cet effet, chaque vêtement est fourni avec un jeu de doublures filtrantes. After contamination with toxic liquids, the garment should be cleaned and the filter liner should be replaced. For this purpose, each garment is supplied with a set of filter liners.

Des modifications de détail du domaine des équivalents techniques peuvent etre apportées au vêtement décrit ci-dessus, sans que lson sorte pour cela du cadre de la présente invention.  Modifications of detail in the field of technical equivalents can be made to the garment described above, without this being outside the scope of the present invention.
