Description

Oppfinnelsen vedrører et vernedraktsystem som kombinerer høy verneevne mot hudpenetrerende, kjemiske stridsmidler, god vindtetthet og vanntetthet, samtidig som den gir lav fysiologisk belastning på brukeren. The invention relates to a protective suit system that combines high protection against skin-penetrating chemical warfare agents, good windproofness and watertightness, while at the same time providing a low physiological burden on the user.

De nå kjente luftpermeable vernedrakter har en oppbygging som er et kompromiss mellom ulike krav som: Høy verneevne mot hudpenetrerende, kjemiske stridsmidler eller andre hudirriterende stoffer, og kravet om at soldatens evne til fysisk utfoldelse skal opp-rettholdes over et bestemt tidsrom. The currently known air-permeable protective suits have a structure that is a compromise between various requirements such as: High protection against skin-penetrating, chemical warfare agents or other skin-irritating substances, and the requirement that the soldier's ability to perform physically must be maintained over a certain period of time.

En slik drakt er beskrevet i NP 128.694 som tilsvarer US-patent nr. 3.818.507.. Such a suit is described in NP 128,694 which corresponds to US patent no. 3,818,507..

Den kjemiske beskyttelse oppnås i prinsippet ved bruk av to barrierer, én dråpebarriere og én gassbarriere. Draktens ytterlag, dråpebarrieren, fanger opp dråper og hin-drer væske i å trenge videre inn i bekledningssystemet. Dampene, fra dråpene avsatt på ytterlaget vil diffundere inn i drakten og fanges opp i gassbarrieren av et absorp-sjonsmiddel f.eks. bundet aktivkull. De to barrierene er adskilt gjennom et luftlag.• The chemical protection is achieved in principle by using two barriers, one drop barrier and one gas barrier. The suit's outer layer, the drop barrier, catches drops and prevents liquid from penetrating further into the clothing system. The vapours, from the droplets deposited on the outer layer, will diffuse into the suit and be captured in the gas barrier by an absorbent, e.g. bonded activated carbon. The two barriers are separated by an air layer.•

På grunn av at man samtidig ønsker at drakten har stor vanndamp-permeabilitet for å redusere den fysiologiske belastningen på soldaten, kan ikke veven i ytterlaget gjøres så tett atden fullstendig forhindrer at store dråper som. treffer ytterlaget med .-høy hastighet, trenger igjennom dråpebarrieren. Væske vil i slike tilfeller raskt mette adsorpsjonslaget under,og draktens beskyttelse er ødelagt. Due to the fact that you also want the suit to have great water vapor permeability to reduce the physiological stress on the soldier, the fabric in the outer layer cannot be made so tight that it completely prevents large drops like. hits the outer layer at .-high speed, penetrates the droplet barrier. In such cases, liquid will quickly saturate the adsorption layer below, and the suit's protection is destroyed.

Draktene gir kun tilstrekkelig beskyttelse brukt utenpå den normale feltbekledning, og de må erstattes av nye en viss tid etter kontaminering. The suits only provide adequate protection when used outside the normal field clothing, and they must be replaced with new ones some time after contamination.

Denne oppfinnelse beskriver et bekledningssystem som langt på vei løser flere av de problemer dagens luftpermeable This invention describes a cladding system that goes a long way towards solving several of today's air-permeable problems

vernedrakter har.protective suits have.

Drakten består av en dråpebarriere over en gassbarriere adskilt ved et luftlag. The suit consists of a drop barrier over a gas barrier separated by an air layer.

Dråpebarrieren består av en raikroporøs membran som lamine-res til en bærevev med bæreveven som utside. Bæreveven gir ytterlaget slitestyrke og mekanisk stabilitet, og kan be-handles slik at drakten får andre spesielle egenskaper som farve, flammedempning o.l.. Den mikroporøse membranen har porer i én slik størrelsesorden at de slipper vanndamp igjennom, men ikke vann, og gir derfor god vanndamptrans-misjon, slik at soldaten kan ventilere ut overskuddsvarme. Samtidig vil membranen fullstendig forhindre at væske kan trenge igjennom ytterlaget, - også store dråper med høy kollisjonsenergi og dråper som ellers kunne presses gjennom ytterlaget. Gjennom at den mikroporøse membranen hol-der dråpene i ytterlaget, kan ytterveven gis en behandling som sprer dråpen ut over en større del av overflaten. Av-, dampningen til atmosfæren økes, belastningen på det innen-forliggende absorpsjonslag reduseres, og kontaktfaren som den kontaminerte overflaten utgjør, reduseres sterkt. The drop barrier consists of a raicroporous membrane which is laminated to a carrier tissue with the carrier tissue as the outside. The carrier fabric provides the outer layer with wear resistance and mechanical stability, and can be treated so that the suit acquires other special properties such as color, flame retardancy, etc. The microporous membrane has pores of such a size that they let water vapor through, but not water, and therefore provides good water vapor transmission -mission, so that the soldier can ventilate excess heat. At the same time, the membrane will completely prevent liquid from penetrating the outer layer, - also large drops with high collision energy and drops that could otherwise be pushed through the outer layer. Because the microporous membrane holds the droplets in the outer layer, the outer tissue can be given a treatment that spreads the drop over a larger part of the surface. Evaporation to the atmosphere is increased, the load on the underlying absorption layer is reduced, and the contact hazard posed by the contaminated surface is greatly reduced.

Ønskes beskyttelse mot varmestråling, kan dette oppnås ved at det velges en mikroporøs membran med høyt smeltepunkt og en hvit farve for god varmerefleksjon. If protection against heat radiation is desired, this can be achieved by choosing a microporous membrane with a high melting point and a white color for good heat reflection.

Under ytterlag/mikroporøs membran vil den normale' gassbarrieren komme. Dråpebarriere og gassbarriere kan være to separate bekledningsgjenstander som også kan utskiftes hver for seg. Systemet krever ikke bruk av den regulære feltbekledning for å gi nødvendig beskyttelse. Beneath the outer layer/microporous membrane, the normal gas barrier will come. Drop barrier and gas barrier can be two separate clothing items that can also be replaced separately. The system does not require the use of the regular field clothing to provide the necessary protection.

Fordelene ved denne oppfinnelse overfor de hittil kjente systemer er at den mikroporøse membranen gir drakten stor-, vanndamp-transmisjon og derfor lav fysiologisk belastning på brukeren. The advantages of this invention compared to the previously known systems are that the microporous membrane gives the suit great water vapor transmission and therefore a low physiological burden on the user.

Den gir en drakt som er vindtett og som er vanntett. It provides a suit that is windproof and waterproof.

Den gir meget høy beskyttelse mot kjemiske stridsmidler ved at dråper ikke kan trenge gjennom til adsorpsjonslaget under, også under trykk. Adsorpsjonslaget belastes bare med damper fra væskeavsetningen på ytterlaget. It provides very high protection against chemical warfare agents in that droplets cannot penetrate to the adsorption layer below, even under pressure. The adsorption layer is only loaded with vapors from the liquid deposit on the outer layer.

Den mikroporøse membranen tillater at ytterlaget får en im-pregnering som sprer dråper av kjemiske stridsmidler på draktens utside. Herigjennom oppnår man at avdampningen til atmosfæren øker, noe som reduserer belastningen både totalt og lokalt på gassbarrieren.Adsorpsjonslagets levetid økes. The microporous membrane allows the outer layer to get an impregnation that spreads drops of chemical warfare agents on the outside of the suit. Through this, it is achieved that evaporation to the atmosphere increases, which reduces the load both overall and locally on the gas barrier. The lifetime of the adsorption layer is increased.

Spredningen av dråper på ytterlaget medfører at kontaktfaren som den kontaminerte overflaten til drakten ellers ut-gjør, sterkt reduseres. Dette gir store operative fordeler. The spreading of droplets on the outer layer means that the risk of contact that the contaminated surface of the suit otherwise represents is greatly reduced. This provides major operational advantages.

Gjennomat ytterveven og adsorpsjonslaget er flammedempende impregnert samtidig som den mikroporøse membranen har høyt smeltepunkt og god varmerefleksjon på grunn av hvit farve, oppnås samtidig beskyttelse mot brannvåpen og varmestråling. Through the fact that the outer fabric and the adsorption layer are flame-retardant impregnated while the microporous membrane has a high melting point and good heat reflection due to its white colour, protection against fire weapons and heat radiation is achieved at the same time.

Drakten krever:ikke at den normale feltbekledning bæres under for å gi nødvendig beskyttelse. The suit does not require the normal field clothing to be worn underneath to provide the necessary protection.

Prinsippet med den mikroporøse membran som dråpebarriere over et adsorpsjonsskikt kan også anvendes til å beskytte hender og føtter mot kjemiske stridsmidler og samtidig transportere svette. The principle of the microporous membrane as a drop barrier over an adsorption layer can also be used to protect hands and feet against chemical warfare agents and at the same time transport sweat.

Oppfinnelsen er ikke bare bundet til militært bruk, men kan også brukes som vernedrakter i f.eks. industri og lignende . The invention is not only bound to military use, but can also be used as protective suits in e.g. industry and the like.
