Description

.Oppfinnelsen vedrører et flerelags sammensatt material for beskyttelsesbekledning, med minst en ikke antennbar tekstilvevnad som ytre sjikt, og et luftgjennomtrengelig varmeisolerende og samtidig skadestoffadsorberende indre sjikt som eventuelt på den fri overflate er dekket med tekstil-dekk-sj ikt. .The invention relates to a multi-layered composite material for protective clothing, with at least one non-flammable textile fabric as outer layer, and an air-permeable heat-insulating and at the same time harmful substance-adsorbing inner layer which, if necessary, is covered on the free surface with a textile-tyre layer.

Det er kjent som ytre sjikt for varmebeskyttelsesantrekk å anvende metallfolier, som reflekterer varmestråling og således muliggjør opphold av personer i området for en slik stråling, eksempelvis ved brannslukning, ved høyovnavstik-ning eller lignende. It is known as an outer layer for heat protection clothing to use metal foils, which reflect heat radiation and thus make it possible for people to stay in the area of such radiation, for example when extinguishing a fire, when blasting a blast furnace or the like.

Også for militært formål er beskyttelsesbekledningen nød-vendig, som beskyttelse overfor varmestråling som opptrer Also for military purposes, protective clothing is essential, as protection against heat radiation that occurs

i ekstreme høyder, men også bare kort innvirkningstid ved anvendelse av kjernevåpen. at extreme heights, but also only for a short time when nuclear weapons are used.

Riktignok er en beskyttelsesbekledning med reflerende metallisk ytre sjikt meget ubrukelig for militært formål på grunn av kamuflering. Det ville også være mulig å Admittedly, a protective clothing with a reflective metallic outer layer is very useless for military purposes due to camouflage. It would also be possible to

legge det reflekterende metallsjikt i det sammensatte materials indre, slik dette er blitt foreslått ved et kjent kuldebeskyttelsesmaterial (DE-OS 2 553 781), ytre sjikt av de kjente sammensatte material er riktignok antennbare, således at metallsjiktet og ytterligere innen-forliggende sjikt må være utformet således at de beskytter bæreren av en beskyttelsesbekledning også for varmeinnvirk-ning av det avbrennende ytre sjikt. lay the reflective metal layer in the interior of the composite material, as this has been proposed in a known cold protection material (DE-OS 2 553 781), the outer layer of the known composite material is indeed flammable, so that the metal layer and further inner layer must be designed in such a way that they protect the wearer of a protective garment also from the heat of the burning outer layer.

Dessuten ligger en hovedulempe ved de kjente materialer In addition, there is a main disadvantage of the known materials

at metallsjiktet for å by en tilstrekkelig strålingsbeskytt-else må være lukket og således luftugjennomtrengelig. that the metal layer, in order to provide adequate radiation protection, must be closed and thus air-impermeable.

Det er spesielt å fremheve at med beskyttelsesbekledning utrustede tropper under kampbetingelser, dvs. under om-stendigheter for tyngste legemlige påkjenning stadig, dvs. under tiden flere dager må bære beskyttelsesbekledning således at beskyttelsesbekledningen av det kjente luftugjennom-trengelige material praktisk talt ikke er anvendbart da den for huden nødvendige luftutveksling ikke kan opprettholdes. For å unngå disse vanskeligheter foreslås i tyske patenter 2 829 599 og 2 843 974 å utforme tekstilvevnaden som tjener som indre sjikt ikke antennbart, mellom det ytre sjikt og det indre sjikt å anordne et fibersjikt av mineralfibre og å fremstille det indre sjikt av et luftgjennomtrengelig skumstoff, hvis porer er fylt med aktive kullpartikler, It is particularly important to emphasize that troops equipped with protective clothing under combat conditions, i.e. under circumstances of the heaviest physical stress constantly, i.e. during several days, must wear protective clothing so that the protective clothing of the known air-impermeable material is practically not applicable then the air exchange necessary for the skin cannot be maintained. In order to avoid these difficulties, it is proposed in German patents 2 829 599 and 2 843 974 to design the textile fabric which serves as the inner layer to be non-flammable, to arrange between the outer layer and the inner layer a fibrous layer of mineral fibers and to make the inner layer of an air-permeable foam material, the pores of which are filled with activated carbon particles,

idet mellom tekstilvevnad og mineralfibersjikt kan det dessuten være anordnet et luftgjennomtrengelig porøst vannsperre-sj ikt. since between the textile fabric and the mineral fiber layer, an air-permeable porous water barrier layer can also be arranged.

De således utformede flerelags^sammensatte material utmerker seg ved en relativ høy bærekomfort ved virksom bortholding av ekstremt høye korttidige varmebelastninger. The multi-layer composite material designed in this way is distinguished by a relatively high level of wearing comfort by effectively avoiding extremely high short-term heat loads.

Ifølge oppfinnelsen dreier det seg nå om å tilveiebringe According to the invention, it is now about providing

et flerelags sammensatt material, spesielt for beskyttelses-klær som utmerker seg ved en høy materialresistens overfor nukleære varmeblitz. a multi-layer composite material, especially for protective clothing, which is characterized by a high material resistance to nuclear heat flashes.

Oppfinnelsen vedrører et flerelags sammensatt material The invention relates to a multi-layer composite material

for beskyttelsesbekledning med minst en ikke antennbar tekstilvevnad som ytre sjikt og et luftgjennomtrengelig varmeisolerende og samtidig skadestoffadsorberende indre sjikt, som eventuelt på den frie overflate er dekket med et tekstil-dekksjikt, idet det mellom det ytre tekstil- for protective clothing with at least one non-flammable textile fabric as an outer layer and an air-permeable heat-insulating and at the same time harmful substance-adsorbing inner layer, which is optionally covered on the free surface with a textile cover layer, as between the outer textile

sjikt og det indre sjikt er anordnet et luftgjennomtrenge- layer and the inner layer is provided with an air-permeable

lig og fleksibelt sperresjikt, idet materialet er karakterisert ved at sperresjiktet er et lysreflekterende appretert, hvitt bleket tekstilsjikt. smooth and flexible barrier layer, as the material is characterized by the fact that the barrier layer is a light-reflecting finished, white bleached textile layer.

Fortrinnsvis er refleksjonssjiktet en hvit, bleket bomullsvevnad som i tillegg på den mot det ytre sjikt vendte side, kan være belagt med et sjikt av f.eks. Preferably, the reflective layer is a white, bleached cotton fabric which, in addition, on the side facing the outer layer, can be coated with a layer of e.g.

sfæriske glassperler eller lignende, som hver har en diameter på minst 0,5 um, og maksimalt 7,0 pm. . Bærekomforten av en av det sammensatte material ifølge oppfinnelsen fremstillet beskyttelsesbekledning, påvirkes ikke på grunn av den luftgjennomtrengelige utforming av tektstil-sjiktet. På den annen side er imidlertid energirefleksjonen overraskende meget høy, idet den i tillegg kan økes ganske betraktelig ved ovennevnte glassperlesjikt. Det sammensatte material ifølge oppfinnelsen egner seg derfor helt spesielt for en militær beskyttelsesbekledning da den formår å holde borte nukleære varmeblitz. spherical glass beads or the like, each having a diameter of at least 0.5 µm and at most 7.0 µm. . The wearing comfort of a protective garment made from the composite material according to the invention is not affected due to the air-permeable design of the tect style layer. On the other hand, however, the energy reflection is surprisingly very high, as it can also be increased quite considerably with the above-mentioned glass bead layer. The composite material according to the invention is therefore particularly suitable for military protective clothing as it manages to keep out nuclear heat flashes.

Tekstilsjiktet ifølge oppfinnelsen tjener fortrinnsvis som erstatning for det i tysk patent 2 829 599 foreslåtte mineralfibersjikt mellom det tekstile ytre sjikt og det luftgjennomtrengelige varmedemmende indre sjikt. Ifølge oppfinnelsen kan imidlertid i tillegg være anordnet det 1 tysk patent 2 829 599 foreslåtte mineralfibersjikt, idet da tekstilsjiktet befinner seg mellom det tekstile ytre sjikt og mineralfibersjiktet. Med hensyn til oppbygning og sammensetning av mineralfibersjiktet henvises det til det som er anført i tysk patent 2 829 599. The textile layer according to the invention preferably serves as a replacement for the mineral fiber layer proposed in German patent 2,829,599 between the textile outer layer and the air-permeable heat-insulating inner layer. According to the invention, however, the mineral fiber layer proposed in German patent 2,829,599 can also be arranged, since the textile layer is located between the textile outer layer and the mineral fiber layer. With regard to the structure and composition of the mineral fiber layer, reference is made to what is stated in German patent 2 829 599.

Videre kan det i tillegg være anordnet et luftgjennomtrengelig porøst vannsperresjikt mellom tekstilsjiktet og mineralfibersjiktet ifølge tysk patent 2 843 974. Med hensyn til vannsperresjiktet refereres til det som er anført i tysk patent 2 843 974. For såvidt er de tyske patenter 2 839 599 og 2 843 974 bestanddeler av foreliggende søknad. Furthermore, an air-permeable porous water barrier layer can additionally be arranged between the textile layer and the mineral fiber layer according to German patent 2 843 974. With regard to the water barrier layer, reference is made to what is stated in German patent 2 843 974. To that extent, the German patents 2 839 599 and 2 843,974 components of the present application.

Vesentlig er at tekstilsjiktet på den til det ytre sjiktet vendte side, er utformet "blendende hvitt" resp. "blendende lyst". Dette kan f.eks. også oppnåes ved at den til yttersjiktet vendte side, utstyres med et sølvlag eller farget sølvaaktig eller også alumineres. Ovennevnte uttrykk "bleket" skal altså bety så meget som "blendende hvitt" resp. "blendende lyst". It is essential that the textile layer on the side facing the outer layer is designed "dazzling white" or "blindingly bright". This can e.g. also achieved by the side facing the outer layer being equipped with a silver layer or colored silver-like or also aluminised. The above-mentioned expression "bleached" should therefore mean as much as "blinding white" or "blindingly bright".

Ovennevnte glassperler er fortrinnsvis påklebet den mot yttersjiktet vendte side av tekstilsjiktet, nemlig således at luftgjennomtrengelighétén bibeholdes praktisk talt fullstendig. Derved anvendes på grunn av den foretrukkede anvendelse av det sammensatte materiale ifølge oppfinnelsen et flammefast klebestoff. The above-mentioned glass beads are preferably glued to the side of the textile layer facing the outer layer, namely in such a way that the air permeability is maintained practically completely. Thereby, due to the preferred use of the composite material according to the invention, a flame-resistant adhesive is used.

Anordningen av tekstilsjiktet mellom det indre sjikt og The arrangement of the textile layer between the inner layer and

det ytre sjikt, kan være løst eller fast. I sistnevnte tilfelle er refleksjonssjiktet påklebet, påsveiset eller påpresset på det indre sjikt. the outer layer can be loose or solid. In the latter case, the reflective layer is glued, welded or pressed onto the inner layer.

Er det indre sjikt på i og for seg kjent måte (tysk patent Is the inner layer in a manner known per se (German patent

1 829 599) et sjikt av luftgjennomtrengelig skumstoff, 1 829 599) a layer of air-permeable foam material,

hvis porer er besatt med aktivkullpartikler, bonderes tekstilsjiktet fortrinnsvis på dette indre sjikt. if the pores are filled with activated carbon particles, the textile layer is preferably bonded to this inner layer.

Ved en porøs anordning av tekstilsjiktet mellom det ytre sjikt og det indre sjikt resp. indre filtersjikt, innsys fortrinnsvis tekstilsjiktet mellom disse to sjikt. In the case of a porous arrangement of the textile layer between the outer layer and the inner layer or inner filter layer, preferably see the textile layer between these two layers.

Med hensyn til oppbygning og sammensetning av det tekstile ytre sjikt og det luftgjennomtrengelige varmeisolerende indre sjikt henvises igjen til tysk patent 2 829 599, som ved hensyn til dette likeledes skal være en bestanddel av foreliggende oppfinnelse. With regard to the structure and composition of the textile outer layer and the air-permeable heat-insulating inner layer, reference is again made to German patent 2 829 599, which, in view of this, shall also be a component of the present invention.

Det er prinsipielt mulig å fremstille beskyttelsesbekled-ningsstykker som f.eks. støvler eller lignende som form-stykker av ovennevnte material. Fortrinnsvis fremstilles imidlertid et banematerial som deretter forarbeides til de ønskede bekledningsstykker. It is in principle possible to produce pieces of protective clothing such as boots or similar as form-pieces of the above-mentioned material. Preferably, however, a web material is produced which is then processed into the desired cladding pieces.

Avsluttende skal det henvises til at det sammensatte material ifølge oppfinnelsen riktignok egner seg spesielt godt for beskyttelsesbekledning, imidlertid ikke begrenset til denne anvendelse. Det er også mulig av dette material å anvende poser, f.eks. til oppbevaring av varmefølsomt material som f.eks. håndradioapparater, sprengkapsler eller lignende. Det er også mulig å anvende dekkduker, soveposer, teltduker og lignende til fremstilling, utrustning av still-inger som skal være beskyttet og for nukleær varmeblitz. Finally, it should be noted that the composite material according to the invention is indeed particularly suitable for protective clothing, but is not limited to this application. It is also possible to use this material for bags, e.g. for storing heat-sensitive material such as e.g. hand-held radios, explosives or the like. It is also possible to use cover cloths, sleeping bags, tent cloths and the like for manufacturing, equipping positions that must be protected and for nuclear heat flash.

Som flammefast klebestoff for påkledning av ovennevnte glassperler på den mot yttersjiktet vendte side av tekstilsjiktet tjener fortrinnsvis en kunststoffkleber som fremstilles ved polyaddisjon av triisocyanter med toverdige alkoholer eller andre hydroksylgruppeholdige forbindelser. Det derved dannede polyuretan oppløses i en keton og blandes i forholdet 9:1 med en egnet handelsvanlig mettet bromoppløs-ning. Ved en times omrøring under luftutelukkelse til-settes langsomt 5 g magnesiumpulver, tørrveiet hver gang på 100 g polyuretan våtveiet. Av denne kunststoffkleber påføres da en mengde på ca. 25 g/m<2> på tekstilsjiktet, A plastic adhesive produced by polyaddition of triisocyanates with dihydric alcohols or other compounds containing hydroxyl groups is preferably used as a flame-resistant adhesive for coating the above-mentioned glass beads on the side of the textile layer facing the outer layer. The polyurethane thus formed is dissolved in a ketone and mixed in a ratio of 9:1 with a suitable commercially available saturated bromine solution. With stirring for one hour under exclusion of air, slowly add 5 g of magnesium powder, weighed dry each time to 100 g polyurethane wet weight. A quantity of approx. 25 g/m<2> on the textile layer,
