The technical FIELD TO WHICH the INVENTION RELATES.

The present invention relates to products comprising a cloth (fabric), resins and films (film layers), which can provide protection from harmful influences, life threatening, such as radiation, chemicals, biological agents, metal missiles and fire. In some embodiments, the implementation of the paintings and films of the present invention is used for the manufacture of clothing with protection from multiple harmful effects and has good heat dissipating properties.

The LEVEL of TECHNOLOGY

Currently there are many types of harmful effects that can cause serious damage or even death. So the e harmful effects include radiation, corrosive or toxic chemicals, infectious biological agents, metal projectiles, such as bullets or shrapnel, and fire. Because many of these harmful effects have been known for many years, it becomes more necessary and more difficult to defend against them in light of the recent terrorist acts, including terrorist attacks of 11 September 2001 on the World Trade Center.

Many of the harmful effects that we face today, is usually considered as localized in places such as nuclear power plants, reprocessing plants, nuclear fuel, nuclear waste disposal, x-ray scanners, refineries and biological laboratories. However, the rise of terrorism has expanded the scope of such harmful effects to almost any location. In the case of nuclear radiation, blast portable nuclear bombs, such as a "dirty nuclear bomb", which includes the waste materials in the nuclear industry, can spread deadly radiation over the entire area of a large city (the suburbs). Similarly, the release of infectious biological agents are no longer limited to biological research laboratories, can occur anywhere where the terrorists decide to release such infectious biological AG the options.

In addition to the need for protection from life-threatening harmful effects acting on large areas, there is also a need to simultaneously protect against many types of harmful effects. For example, although one can clearly foresee the danger of radioactive contamination from the nuclear power plant, the occurrence of terrorism means that currently there is a probability that a deadly biological agents or chemicals may be released within the same nuclear power plant. Similarly, despite the fact that trying to protect against leakage of deadly biological agents from biological research laboratories, the explosion of a terrorist "dirty nuclear bomb" near the laboratory can cause serious radiation hazard. Therefore, there is no possibility of effective enforcement, just given the most anticipated types of harmful effects.

What is now needed is a method effective and economical protection against many types of harmful effects. In the past, for example, clothing was designed to protect against specific threats. In the case of radiation have been made some attempts to suppress the harmful effects of the adjali by developing service, impervious to radiation. Usually such clothing, impervious to radiation, consists of a rigid material, such as rubber with a filler in the form of lead or any other heavy metal, which is able to delay radiation. Examples impervious to radiation service, impregnated with lead, can be found in Holland, U.S. patent No. 3052799, Whittaker, U.S. patent No. 3883749, Leguillon, U.S. patent No. 3045121, Via, U.S. patent No. 3569713, and Still, U.S. patent No. 5038047. In other cases, opaque to radiation materials incorporated in the polymer fiber as the Shah, U.S. patent No. 5245195, and Lagace, U.S. patent No. 6153666.

Also features clothing designed to protect against metal projectiles, such as bullets or shrapnel. For example, Borgese, U.S. patent No. 4989266, and Stone, U.S. patent No. 5331683, reveal two types of bulletproof vests.

Additionally, developed blade to provide resistance to corrosive and toxic substances. Examples of such chemical protective cloths can be found online. Such chemical protective cloth includes plastic canvas, such as DuPont's Tyvek®polypropylene fabric, such as Kimberly-Clark's Kleenguard®or Kappler''s Proshield®, plastic laminate fabric such as DuPont's TyChem®or Kimberly-Clark's HazardGard I®and paintings based on microporous film, so is e as DuPont's NexGen ®or Kappler''s Proshield 2®. Such chemical protective cloth also provide protection from biological agents.

Along with the fact that these canvases, connections, and clothing prior art offer protection against certain types of threats, against which they are designed, they have several drawbacks. For example, despite the fact that clothing prior art impregnated with lead, provides a good measure of protection from the destructive effects of radiation, such clothing prior art is often heavy, hard, expensive and bulky. Thus, such clothing is often uncomfortable, cumbersome and restrictive movement. In addition, the lead, of course, is a toxic substance that must be handled very carefully, and cannot be disposed of without proper control. In addition, there are problems associated with sterilization and decontamination of such previous service the prior art, since it is usually quite large, expensive and toxic for disposal after each use.

Similarly, bulletproof vests, and explosion-proof suits of the previous prior art tend to have the properties of a weak calarasanu. These bulletproof vests and explosion-proof suits can be quite not the sort to wear, when the weather was so hot that the user should choose, it is better to refuse protection, rather than risk getting overheating. Such weak teplonasosnye also has another disadvantage in military applications. If the heat of the soldier's body increases inside a bulletproof vest or explosion-proof suit, soldiers will be high, so-called "thermal signature" in other areas of the soldier's body, where it can stand the heat. This uneven thermal signatures" can lead to what is easily the soldier thermal photodetector enemy. For the sake of survival in high-tech battle for the soldier better quickly select the heat his body and thus have a uniform "heat signature".

In addition, it is possible that the clothes are designed to be effective against one of the harmful effects may not be as effective against other harmful effects. For example, protects against radiation clothing prior art are likely to be ineffective to delay bullets. Conversely, bulletproof vests, and explosion-proof suits will be ineffective to delay radiation.

DISCLOSURE of INVENTIONS

The present invention relates to products, including paintings and film layers, which can protect from many in the region influences, including the harmful effects of radiation, chemical and biological agents, metal shells and fire. In some embodiments of the present invention paintings and films of the present invention are used for making clothing with protection against many harmful effects and with excellent properties calarasanu. In other embodiments of the present invention, the protective sheet or film can be used for the manufacture poncho, protective tents, a probe for detecting radiation, Wallpaper, exterior cladding of buildings, roofing materials, composite Foundation for buildings or facing material for cabins of commercial aircraft, airport scanner, a device for radiation food irradiation or x-ray room. In addition, the materials of the present invention can be included in the composition of the dye or coating and printed on many kinds of surfaces.

Protects against radiation, the compounds preferably are developed by mixing protect from radiation material, such as barium, bismuth, tungsten or their compounds with powdered polymer, a granular polymer or liquid solution, emulsion or suspension of the polymer in the solvent or water. The polymer can mainly be selected from a wide range of plastics, including, without limitation, urethan, polyamide, polyvinyl chloride, polyvinyl alcohol, natural latex, polyethylene, polypropylene, ethylene vinyl acetate and complex polyester. Then protect from radiation polymer mixture is combined with one or several layers of cloth.

Then other types of protection from the harmful effects can be combined with protection against radiation. For example, opaque to radiation polymer composite can be laminated to one or more commercially available fabrics, which provide protection from exposure to chemicals, biological agents, metal shells and fire. Commercially available cloth includes plastic canvas, such as DuPont's Tyvek®polypropylene fabric, such as Kimberly-Clark's Kleenguard®or Kappler''s Proshield®, plastic laminate fabric such as DuPont's TyChem®or Kimberly-Clark's HazardGard I®and paintings based on microporous film, such as DuPont's NexGen®or Kappler''s Proshield 2®, composite material, containing carbon spheres, such as Blucher GmbH's Saratogaand aramid fabric such as DuPont's Kevlar®or Nomex®.

Alternatively, the film can provide protection from harmful chemicals, biological agents, fire or metal shells may be l is mined or glued some way to protect against radiation canvas or film of the present invention. This additional film can be made from various polymeric materials such as polyethylene, polypropylene, polyurethane, neoprene, polytetrafluoroethylene (Teflon®), Kapton, Mylaror their combinations.

If taken into account the heat, humidity or thermal signature of the soldier, protects against radiation polymer mixture prior to application to one or more layers of fabric can be added heat dissipating compounds, such as copper, silver, aluminum, gold, beryllium, tungsten, magnesium, calcium, carbon, molybdenum and/or zinc. Alternatively, a polymeric heat-dissipating layer can be specially designed and taped to protect from radiation to the canvas.

Protects against radiation canvas, one or merged with other layers (e.g., chemical protective, heat)may be included in a bulletproof vest or explosion-proof suit. Usually, bulletproof vests, and explosion-proof suits are constructed with aramid and/or plastic layers of fabric that are sewn together. To add protection from radiation to such a bulletproof jacket or explosion-proof suit protects from radiation layer of fabric may be sewn between the aramid and/or plastic layers of fabric or laminated on them. Chemical and bi is the logical protection can also be achieved by crosslinking chemical protective films with aramid and/or polyethylene bulletproof paintings or laminating.

Using similar principles known flame retardant fabric, such as Nomex aramid®or Kevlar®paintings produced by DuPont, can be combined with bullet-proof, protects against radiation, chemical resistant, biologically stable and/or heat dissipating layers of fabric of the present invention, either by sewing or lamination to develop a service, which provides protection against many kinds of harmful effects, life-threatening. Such clothing can be described as "universal" protective clothing. The principles of the present invention can also be applicable to a wide range of other products, including surgical hoods, hospital gowns, gloves, blankets for patients, poncho, partitions, coverings, coveralls, uniforms, overalls, tents, pouches, bags, Wallpaper, wrapping material, dry plaster, the outer wall of the buildings, the foundations of buildings, radiation probes and other Advanced, transparent elements having the properties of opacity to radiation, such as impregnated protective eyewear can be attached to or included in the protective clothing of the present invention.

DETAILED description of the INVENTION

Figure 1 shows covering all the body suit 10, which is made of cloths of the present invention, protects from harmful effects. To protect the entire surface covering the entire body suit 10 should be preferably one-piece jumpsuit that covers every part of the human body. Can be used elastic cuffs 12, 14 around the areas of the hand and foot to provide a snug fit. Alternatively gloves 16, the shoes 18 and the head 20 can be separate parts, which are covered with a stock jumpsuit so that would not look out of the skin surface. Covering all the body suit 10 may also include a fastener in the form of hooks and loops or valve 28 zipper, to allow the user to easily dress covering the entire body suit 10.

Transparent flap 24 to the eye preferably included in covering all the body suit 10 to protect persons For the convenience of the flap 24 to the eye may be mounted on hinges, such as corner rivets 26, to allow the user to recline plate 24 up and down. Alternatively, the shield for the eyes can be a standard device such as safety glasses (not shown). To provide protection from radiation in the flap 24 to the eye preferably inserted leaded glass or similar protection from radiation glass.

Figure 2 shows the cross-section of the composite fabric 50 with intermediate protects against radiation polymer layer 60, which can be used for covering the entire body costume of figure 1 to provide protection from radiation. In figure 2, the intermediate polymer layer 60, which includes protecting against radiation materials 62, 64, 66, 68 in addition to the polymers 52, enclosed between two layers of fabric or other material 34, 36. External fabric or other material 34, 36 preferably is smooth and soft. It may be, for example, non-woven polymeric fabric, such as polypropylene, polyethylene, aramid fabric, rayon, or any mixtures thereof. Alternatively, the external fabric or other material can be a woven fabric, such as cloth, or may be another smooth, soft material such as paper or film.

As protects against radiation materials preferably the m choice for the present invention are barium sulfate, tungsten and bismuth, as, for example, compared with lead they are lighter, cheaper and have fewer known harmful effects on health. Can also be used to protect against radiation materials, including, but without limitation, barium, other compounds of barium (e.g., barium chloride), compounds of tungsten (e.g., tungsten carbide and tungsten, bismuth compounds, tantalum, tantalum compounds, titanium, titanium compounds, diatrizoate meglumine Inj. USP (sold Nycomed Corporation under the trademark HYPAQUE), acetrizoate sodium, boron, boric acid, boron oxide, boron salt, other compounds of boron, beryllium, beryllium compounds, bonamici-sodium, diatrizoate sodium, ethiopiaeritrea oil, openseminar acid, jokaroo acid, iotechnology acid, iodipamide, iodixanol, iodothyronine oil, idelfonso acid, o-iodohippurate sodium, tetraiodophenolphthalein sodium, iteracy, logicnow acid, iohexol, homepagebuy acid, iopamidol, ianoiuo acid, iopentol, yogendra, openexternal acid, iopromide, ironaway acid, opidol, jobidon, totalmove acid, iotrolan, ioversol, ioxaglate acid, ioxilan, ipodate, acetrizoate of meglumine, meglumin-detrital metical sodium, metrizamide, merisavo acid, penbutolol, fanaticaly sodium, propyliodone, iodomethane sodium, Cotidianul acid, oxide of thorium and tripnet sodium. Such opaque to radiation materials can be purchased from various companies that sell chemicals, such as Fisher Scientific, P.O. Box 4829, Norcross, Georgia 30091 (tel: 1-800-766-7000), Aldrich Chemical Company, P.O. Box 2060, Milwaukee, Wisconsin (phone: 1-800-558-9160) and Sigma, P.O. Box 14508, St. Louis, Missouri 63178 (phone: 1-800-325-3010). For best protection from radiation preferred smaller particle sizes protect from radiation materials, such as submicron dimensions. However, the additional cost when buying such small particles must be correlated with the importance of the additional protection that will be achieved. Specialists in the art will readily understand that other protecting from radiation materials comprising the same metal may be used interchangeably with the above materials.

In protecting against radiation composite fabric 50 of figure 2 protects against radiation material embedded in the polymer mixture 60. Polymer blend of 60 preferably includes a polymer 52, one or more protecting from radiation materials 62, 64, 66, 68 and one or more additives. Polymer 52 can be selected from a wide range of plastics, including but not limited to, polyurethane, polyamide, polyvinyl chloride, polyvine the new alcohol, natural latex, polyethylene, polypropylene, ethylene vinyl acetate (EVA) and complex polyester. Supplements are usually chemical substances to improve flexibility, strength, durability or other properties of the final product and/or to ensure appropriate uniformity and consistency of the polymer mixture. Such additives can be, as appropriate, plastificator (for example, epoxydecane soybean oil, ethylene glycol, propylene glycol, etc.), emulsifiers, surfactants, suspendresume agents, equalizer, activators drying, amplifiers fluidity etc. Professionals in the plastics industry well-known methods of selection and use of such additives.

The proportions of these various ingredients of the polymer mixture can be different. When using larger share of protecting against radiation materials in General will be provided stronger protection against radiation. However, if the proportion of protecting against radiation materials is too high, the polymer mixture may become brittle when dried or cooled, and it is easy to fall to pieces. The inventors found that more than 50% of the polymer mixture by weight may be barium sulfate, tungsten, bismuth or other protect from radiation material, and the greater part of the remaining mixture consists of a polymer.

the La of its industrial manufactured under the brand DEMRONprotects against radiation connection, cloth and covered the whole body of the costume, sold by Radiation Shield Technologies, Inc. from Miami, Florida, inventors typically use polymer mixture for protecting against radiation compounds containing approximately 85% by weight, protects against radiation materials and approximately 15% by weight of the polymer. In the currently preferred combination protects against radiation materials used in the polymer mixture DEMRONis a tungsten (75%), barium sulfate (20%) and bismuth (5%). Presently preferred polymers used in the polymer mixture DEMRONrepresent ethylvinylacetate (EVA) and polyethylene. Currently, the preferred outer layers of the fabric used in DEMRONrepresent the woven cloth and non-woven fabric, such as canvas from the flash-spinning of polyethylene, recycled bullet forming DuPont's Tyvek®and TyChem®. Using paintings Tyvek®or TyChem®for DEMRONhas the advantage that it protects against radiation properties DEMRONadded chemical and biological protection.

Similar to the commercial product DEMRONinventors intermediate polymer layer 60, as shown in figure 2, includes several who ipov protect from radiation materials 62, 64, 66, 68. Such protecting from radiation materials 62, 64, 66, 68 can be, for example, a compound of barium 62, the connection tungsten 64, a compound of bismuth 66 and the connection of iodine 68. By using many different protect from radiation materials protect against radiation, the product may be more effective when the delay of different types of radiation than a similar product with a one protect against radiation material. For example, some protect from radiation materials can be more effective when the delay of the beta particles, while others may be more effective if delayed gamma rays. Using both types protect against radiation materials in protecting against radiation canvas or other material of the present invention, the product will have improved ability to delay as beta particles, and gamma rays.

In this regard, it is appropriate to consider the use of lead as one of protecting against radiation materials for such hybrid applications, or even more generally, for the type of plasticized materials disclosed in the present invention. Although because of their potential harmful effects on the health of lead may not be preferred as the other protects against radiation materials listed previously, however, lead can be used in plasticized protect the surrounding from the radiation of the mixture or in some other applications of plastic films.

In applications in which it is important to protect from radiation clothing or furniture to have air permeability, such as a surgical mask or when in very hot and humid environment is used to cover the entire body suit, two protecting from radiation layer 110, 112 previously described type can be perforated and are staggered, as shown in figure 3. As shown in figure 3, two protecting from radiation layer 110, 112 are separated by a gap 114. To prevent the gap 114 from closing the gap 114 can be filled very porous woven or nonwoven fabric, such as cloth (not shown). Both of the two protect against radiation layers 110, 112 are perforated to create a pattern of holes 116, 118, 120. Posted by the location of the holes 116, 118, 120 in two sheets 110, 112, as shown in figure 3, the radioactive particles that move strictly in a straight line, will be delayed at least one of the two layers, while for air, which can bend around obstacles, will be provided the opportunity pass.

In the same way protect against radiation materials described previously, or aluminum, can be formed into fibers and woven into clothing or bound with the usual material for clothing, such as cloth, to ensure both flexibility cloth clothing, and protection from radial and service, containing metallic lead. Protects against radiation material may also be included in the set of transparent plastics and glass to create, for example, a transparent plate 24 to the eyes of the type shown in figure 1, having the properties of opacity to radiation. In another alternative embodiment of the present invention the materials to make them properties of opacity to radiation can be placed perforated or non-perforated sheets clean protects from radiation materials, such as aluminum.

Figure 4 shows a second approach to enhancing protection from radiation by using a specific multilayer structure 80. Each of the layers 81, 82, 83 of this layered product of the 80 has a different thickness. Despite the fact that a layer of the same thickness 81 may be able to stop the radiation 84, characterized by a certain wavelength, it can allow to pass radiation 86, characterized by a different wavelength. However, by amplifying the first layer additional layers with different thickness increases the chance of a stop different types of radiation, regardless of their wave characteristics. As another example, the layers 81, 82, 83 can be constructed from different protect from radiation materials. For example, the inventors discovered, chisawasawa from radiation materials with barium, the tungsten and/or bismuth provide cost-effective protection against alpha and beta particles, but does not provide sufficient protection against neutrons. To ensure the best protection against neutrons, the inventors have developed a film for greater efficiency densely populated protect from radiation materials, boron and/or beryllium. This film with boron and/or beryllium can mainly be about 50% by weight, protects against radiation materials and about 50% by weight of the polymer and additives. To provide cost-effective protection from alpha, beta particles and neutrons effective approach could be to unite the polymer layer containing the compounds 81, namely, barium, tungsten and/or bismuth, with a polymer layer containing compound 82, namely boron and/or beryllium. As it is obvious to experts in the field of technology, a synergistic effect can also be achieved by combining different protect from radiation materials 62, 64, 66, 68, as shown in figure 2, using layers of different thickness 81, 82, 83, as shown in figure 4, to create a protect from radiation products, which offers the maximum amount of protection from radiation at a given weight and thickness.

On figa, 5B and 6 shows that many kinds of clothes can be created from film and paintings of this izobreteny is, protects from harmful influences, and are not limited to covering all the body suit 10 shown in figure 1. On figa, for example, shows the front view of the medical apron 130, which is constructed from a film, and the fabric of the present invention, protects from harmful effects. Shown apron 130 covers the chest 132, the upper part of the arms 134 and neck 136 user foil or fabric, protects from harmful influences, such as protecting against radiation canvas, discussed above. As it is obvious to experts in the field of technology, this apron 130 can cover a greater or smaller part of the body to provide the desired level of protection. Part of the apron 130 constructed round belts 138, which is located in the lower part of the waist, to more tightly fit the apron 130 to the user's body. This round straps 138 may mainly include a fastener in the form of hooks or loops (not shown) to provide a tight hold of the ends 139 of the strap together.

Figv represents a rear view of a medical apron 130 on figa. This rear view shows how the coils straps 138 intersect behind so that the ends 139 could meet in front of the apron 130. This rear view also shows the connecting string 140 in the upper part of the body that holds the apron, closely adjacent to the upper part of the torso of the user. Again, p is imushestvenno can be used fasteners in the form of hooks or loops (not shown) for fastening, with the ability to disconnect at least one end of the connecting straps 140 in the upper part of the body with medical apron 130. On FIGU open area 142 left behind medical apron 130 so that the entire apron sits more freely on the body of the user. This region 142 remains open, under the assumption that the front and sides of the user may be more vulnerable to the harmful effects than the back of the user. Of course, if the back of a user is in danger, this region 142 should not remain open.

Figure 6 shows that the film and the fabric of the present invention, protects from the harmful effects can be created in the form of a suit 150 of two parts. Such a suit two piece set includes pants 152, jacket 154 and the head 158 made of films or paintings of the present invention, protects from harmful effects. Strap 156 may be used for tight fixing jackets regarding pants 152. Also to provide protection from inhalation of hazardous gases may be used a gas mask 159. Compared to covering all the body suit 10 shown in figure 1, such a suit 150 two parts are preferred for military applications where flexibility is needed. For example, on a hot day soldier may wish to wear only pants 152 and the belt 156 to save prochla is, having at hand the jacket 154, the head 158 and the mask 159 in case of imminent chemical, radiation or biological hazards.

7-10 shows that for the materials of the present invention, protection from harmful influences, their applicability is not limited to paintings and clothing. 7 shows, for example, as the protect from radiation materials can be included in the composition of dry plaster 120. In this case, protects against radiation materials of the present invention, such as barium sulfate, tungsten or bismuth, can be mixed with gypsum, commonly used in dry plaster, and then 122 placed between two layers of cardboard 124, 126.

On Fig and 9 shows how the materials of the present invention, protection from harmful influences, can be used in other construction applications. On Fig, for example, shows a cross section of the wall 160 of a type that can be used for homes or other buildings. This wall 160 may include a dry plaster 162, insulation 166, the outer covering 164, the outer absorbent paper 168 and facing 169 homes. Types of protection from the harmful effects of the present invention can be incorporated into any or all of these layers of the wall. The inclusion of radiation protection in normal dry plaster has already been discussed in connection with Fig.7. Protects against radiation mA the materials, such as barium sulfate, tungsten or bismuth can also be blended with or napisany on insulating material 166. Facing 169 houses used in design, is often a plastic film, such as DuPont's Tyvek®. As described earlier for DEMRONcanvas inventors, radiation protection can be added to the blade type Tyvek®from the flash-spinning of polyethylene by laminating protects against radiation polymer mixture into sheets of Tyvek type®. Using a similar lamination or other methods of attachment, you can add protection from radiation in the material most commonly used for external cladding 164 and the outer absorbent paper 168.

Figure 9 shows how can be added protection from the harmful effects of the Foundation 170 houses or other buildings. Such a Foundation may consist of reinforced concrete 174, which are boards 172 flooring (floor) and the wall 160 of the house or building. To provide protection from radiation, such as radon, which penetrates from the soil at the bottom, protecting against radiation materials, such as barium sulfate, compounds of tungsten or bismuth compounds may be mixed with reinforced concrete 174 used in the base 170. Alternatively, the film layer or canvas 176 of the present invention may be placed between the reinforced is the first concrete 174 and boards 172 flooring Foundation 170. The same principles can be used to protect the roof (not shown) of a home or building from the penetration of solar radiation. In the case of a roof protecting from radiation materials can be mixed with external roofing material (e.g. ceramic tiles), laminated on the outer roofing material (e.g., roofing tile), and/or between the outer roofing material and interior roofing structure may be placed in film or canvas 176, shown in Fig.9 type that protects from the harmful effects.

Figure 10 shows how the composite protects against radiation, the compounds of the present invention can be used to create objects obtained by injection molding. The object obtained by molding under pressure, shown in figure 10, represents the probe 180 for measuring radiation, which can be inserted into the ground and used to assist in the search for deposits of radioactive materials. This probe 180 measuring radiation includes sliding the outer sleeve 182, the inner housing 184, box 188 registration and flange 186 which is used as a stopper for moving the outer sleeve 182. Still the problem of measuring such radiation probes consisted in the fact that they missed so many extraneous radiation through the outer sleeve 182 and the inner housing 184 that Tr is the bottom was to obtain accurate reading, whether the detected radiation coming from the direction of the window 188 registration. To solve this problem sliding the outer sleeve 182, the inner casing flange 184 and 186 may be made of types of plastic mixture, which included protecting from radiation materials that were previously described. As stated previously, adding a greater proportion protect from radiation materials in the mixture typically gives greater protection from radiation, but if the proportion of protecting against radiation materials is too high, the polymer mixture may become brittle in the drying or cooling and can easily be broken down into pieces. In this sense, the proportions of the polymer and protects against radiation materials shall be selected so as to create a solid probe, because it is produced by casting under pressure, which, on the other hand, should be sufficient to protect against radiation materials to detain background radiation. By using protect from radiation polymer blends of the present invention in the probe 180 measuring radiation in figure 10 registered radiation can be more confidently attributed to the radiation passing through the window 188, than to radiation passing through other parts of the probe 180.

Figure 11 shows the cross-section 200 of the composite fabric that can protect you from harm who's influences, life-threatening in addition to the protection from radiation, such as the harmful effects of toxic chemicals, infectious biological agents, fire and metal shells. Part of such a composite fabric that protects against many harmful effects, are the above three-layer composite fabric with anti-radiation polymer mixture 34, 36, 60 (see figure 2). These three layers 34, 36, 60 added additional layers 210, 220, 230, which can protect from harmful effects. For example, the three protecting from radiation layers 34, 36, 60 can be added non-porous protection layer 210 and/or 220. This non-chemical layer may be either a polymer film 210, which is sealed on three protects against radiation layer 34, 36, 60, and/or chemical protective blade 220, which is sewn or otherwise attached to the three protecting from radiation layers.

Such chemical protective layers 210, 220 may be made from known chemical protective polymers and/or paintings. For example, one of the known classes of chemical protective cloths are non-woven textile, such as a sheet of flash-spinning-polyethylene sold by DuPont under the trademark Tyvek®polypropylene fabric, such as Kimberly-Clark's Kleenguard®, Kappler''s Proshield 1, Lakeland's Safeguard 76the fabric is a mixture of polyethylene with polypro the om and paintings based on cellulose, such as DuPont's SontaraKimberly Clark's Previal. This type of non-woven textile may be a type of plastic films, laminated on one or both sides of the nonwoven fabric, comprising a series of paintings DuPont's TyChem®canvases Kimberly Clark's HazardGard I, II®series of paintings Kappler''s CPFand Responder, and ILC Dover's Ready fabric 1. Such non-woven textiles usually can be combined with three protects against radiation layers 34, 36, 60, be bound or stitched fabric together otherwise.

Chemical protection can be provided by using PVC and/or chlorinated polyethylene film, such as ILC Dover's Chemturion. Such films can be laminated or extruded into three protects against radiation layer 34, 36, 60 of the present invention.

Another class of chemical protective layer is a polymer film with microscopic pores, laminated to the fabric, such as Gore-tax®or cloth polypropylene based, such as DuPont's NexGen, Kimberly Clark's Kleenguard Ultra, Lakeland's Micro-Maxand Kappler''s Proshield 2. Additional chemical protection can be provided with materials, including absorbent layer, such as a combination of carbon/canvas sold Blucher GmbH and Lanx. Another class of Hisashi what's paintings is a woven fabric, covered with rubber or plastic with one or two sides. These are covered with a cloth include polyvinylchloride and nylon composites, composites polyurethane/nylon, composites neoprene/aramid, composites butyl/nylon, composites chlorinated polyethylene/nylon, polytetrafluoroethylene composites (i.e. Teflon®)/fiberglass and composites chlorobutyl/aramid.

Because of chemical protective layer 210, 220 preferably is non-porous, it will also provide protection against infectious biological agents.

Although the painting, shown at 11, can provide a wide range of species protection only the addition of chemical protective layer 210, 220 to the three protecting from radiation layers 34, 36, 60, however, additional or alternative layers 210, 220, 230 may also be selected for protection from additional harmful effects or to facilitate heat dissipation. For example, where chemical protection layer 210 is a plastic laminate layer 220 on 11 may be another layer of woven or non-woven cloth, and the layer 230 may be fire-resistant layer, such as layer, made of fire-resistant aramid Nomex fabric®the production of DuPont. Other types of fire-resistant materials include a combination of aramid paintings Nomex®and Kevlar®such as selling Southern Mills, combines and melamine resin with aramid fibers, the combination of polytetrafluoroethylene (i.e. Teflon®with aramid fibers, a combination of viscose from aramid fibers, combinations of polybenzimidazole with aramid fibers, combinations of polyphenylisocyanate with aramid fibers, combinations polyimide with aramid fibres and plastic films Mylar. Alternatively, the layer 230 may be a layer that is resistant to bullets or shrapnel, made from aramid and/or polyethylene fibers, delaying bullets.

Alternatively, it would be reasonable to form a layer 230 of the heat dissipating material. One way of forming a heat dissipating layer is mixing compounds with high heat conductivity, such as silver, copper, gold, aluminum, beryllium, calcium, tungsten, magnesium, zinc, iron, Nickel, molybdenum, carbon and/or tin, with the polymer in the same way, which is mixed with the polymer protects against radiation materials for forming protecting from radiation layer 60.

Although figure 11 shows six-plane fabric 200, protecting from harmful influences, specialists in the art will easily understand that the multilayer fabric that protects from the harmful effects can be created with a larger or smaller number of layers than six. For example, can be omitted layers 34, 36, 220 woven is whether non-woven cloth, shown figure 11. There is also the possibility to combine different layers to protect from harmful influences or heat, together in one layer. For example, although found to protect against radiation layer 60 of the present invention itself provides excellent heat dissipating properties such heat dissipating properties can be enhanced by adding good conductors of heat, such as silver, copper and/or aluminum, to the mixture is opaque to radiation of materials to protect from radiation layer 60.

On Fig shown bulletproof vest 300, which has the additional property protection from the harmful effects. A large part of the bulletproof vest 300 is a conventional design, such as that shown in Borgese in U.S. patent No. 4989266, the disclosure of which is given in this specification in its entirety by reference. Bulletproof security is provided mainly by layers of polyethylene fibers 314 and/or aramid fibers 316. Commercially available plastic canvas used for bulletproof vests, include series ultra high molecular weight polyethylene fibers Honeywell's Spectraand ultrasonometry polyethylene fibers Honeywell''s Spectraguardthat also includes Steklovolokno is. Commercially available aramid fiber used in bulletproof vests, include a series of aramid fibers DuPont's Kevlar®and a series of aramid fibers Akzo''s Twaron. In this preferred example, the bulletproof vest has one or more layers of aramid fibers 316 located between layers of polyethylene fibers 314. For more significant layer of protection from bullets and shrapnel usually create more layers of aramid fibers 314 and/or polyethylene fibers 316. Additional stability can be created by applying layers of bulletproof material one upon the other on the orientation 90 degrees and encapsulating them between layers of thermoplastic. To ensure higher levels of security can be added to the ceramic material and the plate. Bulletproof vest 300, shown in Fig.7, preferably held together by the cover 312 of the canvas.

For additional protection against harmful interference in a bulletproof vest 300, shown in Fig, can be inserted an extra layer 320 of the type shown in figure 2, 4 or 11. This additional layer 320 in one of the embodiments may be a composite protects against radiation layer 50, 80 shown in figure 2, and 4 types. By adding this protects against radiation layer 50, 80 in the pool is impenetrable vest can be achieved protection from radiation, and from bullets and shrapnel. Similarly, you can protect against fire, chemical and/or biological protection through the use of multi-layer fabric of the type described in connection with 11. In the case of protection only from radiation will usually be desirable to add a layer 320 so that put it closer to the user's body to obtain the advantages of excellent heat dissipating properties, protects against radiation layer 50, 80 of the present invention. On the contrary, in the case of canvas, providing protection from fire, chemical and biological protection, it will usually be desirable that the layer was located closer to the outer side of a bulletproof vest to prevent the ingress of pollutants in bulletproof vest 300.

On Fig-20 shows the different methods of production which can be mostly used to create canvases of the present invention, protects from harmful effects. On Fig, for example, shows the mode of production, which is specifically suitable for mass production is opaque to radiation of paintings or other smooth soft materials of the type shown in figure 2, for use in clothing and other products. On Fig the process begins with one or more bobbins 430, 432 with canvas or other flat soft material 34, 36, nekotoroe applied polymer mixture. A non-woven fabric, such as polypropylene, polyethylene, aramid, rayon, or any mixture is preferred for this process because it found that such a polymer fabric is well contacted with a liquid polymer mixture and, in some cases, provide specific types of protection from the harmful effects. Alternatively, this process can be carried out with the use of woven fabrics, such as cloth and other flat soft materials, such as paper or film. To enhance the ability of a fabric or other material 34, 36 to contact with the polymer mixture can be applied to a cloth or other material by corona discharge by means of one or several installations corona treatment, 438, 439.

In this process protects against radiation liquid polymer mixture is applied on the one hand non-woven cloth or other material 34 through the use of the device 440 application. Such a device application 440 can usually have the platen 442 to laminating a thin layer (for example, preferably 0.1 to 20 millimeters in thickness) of the liquid polymeric mixture to the side of the non-woven cloth or other material 34.

After the device 440 application of the cured leaf 444 then preferably passes through the furnace 446 with hot air for partial drying t is nkiye layer polymer mixture before as it gets to the device 448 lamination. In the device 448 lamination coated fabric 444 preferably combined, when heated and under pressure, with the second sheet of fabric or other material 36 to create protection from the radiation of the blade 50 in the form of a sandwich. Then protect from radiation canvas or other material in the form of a sandwich can be perforated and/or stamped, optionally, in the device 452 punching/stamping. Usually end protects against radiation product can then be wound on the bobbin end 454 for shipment to the appropriate location for use in your clothes or other products. Although in this example in figure 4 shows two layers of cloth or other material 34, 36, alternatively, it is possible to apply the polymer mixture on a sheet of canvas or other material 34 (i.e. like an open sandwich).

On Fig shows an improved version of the process illustrated in Fig, where you can create a canvas with many types of protection from the harmful effects. Like pig two bobbins with the canvas 430, 432 and device 440 application can be used to create protection from radiation blade type shown in figure 2 in the form of a sandwich. To add protection from bullets and shrapnel two bobbins with the canvas 430, 432 can be bobbin with a cloth, have them aramid and/or polyethylene fibers protect from bullets. To give additional protection in the process can be added a third bobbin 470 with the fabric and a second device 476 application. The canvas on the reel 470 can usually be as woven, nonwoven or resistant to bullets canvas as on reels 430, 432. A second device 476 application preferably should then give a liquid polymer mixture property of another, non-radiation protection from harmful influences, such as chemical, biological protection, or protection against fire. Alternatively, the liquid polymer mixture from the second device 476 application may cause heat dissipating layer having good conductors of heat, such as silver, copper or aluminum, embedded in the polymer mixture.

On the device 484 lamination protects against radiation fabric sandwich together with an additional layer 480 paintings, protection from harmful influences, to create a composite fabric 490, which has many kinds of protection from the harmful effects. Then the composite fabric 490 may be perforated and/or stamped, if desired, the device 452 punching/stamping and then wound on the bobbin end 494. However, where the additional layer provides chemical and/or biological protection, this stage of the punching or stamping should not be performed.

On IG shows a second conventional type of process to produce nonwoven materials of the present invention, protects from the harmful effects. In the process Fig ingredients 570 polymer mixture is placed in the hopper of the first extruder 572. To achieve protection from radiation polymer mixture 570 preferably includes one or more opaque to radiation materials and one or more additives. In this process these ingredients 570 polymer mixture can be made in the hopper 571 in solid form. Because hopper 571 directs ingredients 570 polymer mixture in the first extruder 572, the ingredients of the polymer mixture is preferably heated to a viscous liquid state and mixed together torque action is supplied by a drive screw 573 extruder. Because it is equipped with a drive screw 573 extruder pushes the ingredients of the polymer mixture from the first extruder 572, the combination of a perforated plate and a rotating cutter 574 chops coming polymer mixture into balls 575. Such balls 575 then preferably placed in the hopper 576 of the second extruder 577. Again, by heating and is equipped with a screw drive 578 melted polymer mixture. When the ingredients of the polymer mixture is extruded from extruder 577, for the extrusion of thin films of viscous polymer mixture 600 at the end of the second extruder 579 used plate with the slit. Such a thin film 600 can mainly be about 0.1-20 mm thickness. To simplify the process of thin film 600 may be made only by the first extruder 572. However, removing the second extruder 577 there are more chances that the polymer mixture is evenly mixed before extrusion.

As in the processes shown in Fig and 14, liquefied polymer mixture in the process according Fig preferably layered between two sheets of fabric or other material 590, 592. As before, the sheets of fabric are preferably retracted from the bobbins 594, 596 canvases. To enhance the binding process again can be used to install corona treatment, 596, 598. In this case, a thin film of viscous polymer mixture 600 simultaneously applied between the two sheets of fabric or other material 590, 592. After a thin film of viscous polymer mixture 600 is placed between two sheets 590, 592, these two sheets 590, 592 then preferably compressed and heated between the rollers of the device 602 lamination, perforined and/or stamp, if desired, the device 604 punching/stamping. To store the destination protect from radiation canvas or other material 606 can then be wound on the bobbin end 608.

On Fig and 17 shows an improved version of the process, p is illyustrirovannogo on Fig, where you can create a canvas with many types of protection from the harmful effects. Like the process TIG process Fig includes an extruder 622 for fabrication protects against radiation film 626. This protects against radiation film create by putting ingredients 620 polymer mixture in the hopper 621. As before, the polymer mixture preferably includes a polymer, one or more opaque to radiation materials and one or more additives. Hopper 621 sends the ingredients 620 polymer mixture in the extruder 622. Once they were in the extruder 622, the ingredients of the polymer mixture is preferably heated to a viscous liquid state and mixed together torque action is supplied by a drive screw 623 extruder. When the ingredients of the polymer mixture is extruded from extruder 622, at the end of the extruder for the extrusion of thin films liquefied polymer mixture 626 is used plate 624 with crack. Optionally, to increase the confidence that the polymer mixture is placed in the hopper 621 extruder 622, mixed evenly, can be used preceding the extruder similar to the extruder 572 on Fig.

Unlike process Fig second extruder 632 in the process pig placed in parallel with the first extruder 622 d is I the simultaneous production of the second film 636, which is linked to protecting against radiation first film 626. Preferably the film 636, produced by the second extruder 632, provides a different type of protection from the harmful effects than the film 626, produced the first extruder 622. For example, since the first extruder 622 can mainly be used for fabrication protects against radiation film 626, a second extruder 632 can mainly be used for the production of additional film 636 for chemical, biological protection or fire protection. For the manufacture of such additional film 636 other type polymer mixture is loaded into the hopper 631, heated to a liquid state and mixed together torque action is equipped with a screw drive 633 of the extruder. Because it is equipped with a drive screw 633 extruder pushes ingredients such other polymer mixture from the extruder 632, for the extrusion of thin films of viscous polymer material 636 at the end of the extruder 632 is used plate 634 with a crack.

Liquefied polymer film 626, 636 of the two extruders 622, 632 then preferably combine in such a way that they are caught between two sheets of fabric or other material 590, 592. As before, the sheets of fabric are preferably wound with coils 594, 596 with the canvas. To enhance the binding process again can be the used setup corona treatment, 596, 598. After the composite film 638 placed between two sheets 590, 592, two sheets 590, 592 then preferably compressed and heated between the rollers of the device 602 lamination and perforined or stamp, if desired, the device 604 punching or stamping. To store the final product 640 with protection from many kinds of harmful effects can then be wound on the bobbin end 650.

On Fig shows how can be used the principles Fig-16 to create paintings with any number of properties, protecting against harmful influences. The process Fig begins with a bobbin with a cloth or other material 656. Sheet 658 pull of such a reel 656 with a cloth and use as the basis for applying the polymer mixture from the extruder 660. As an example, the sheet 658 may be a fabric that protects from bullets and shrapnel, made from aramid and/or polyethylene fibers, and polymer layer 661 may be the type of protecting against radiation polymer mixture described previously. Alternatively, the sheet 658 may be a fabric, such as a sheet of flash-spinning of polyethylene, polyvinylchloride or polypropylene chemical protective fabric or aramid fabric with protection from fire. Using a second extruder 670, then increase the canvas 664 can be added an extra layer of material, usiwausiwa from harmful influences, such as a polymer layer with a chemical or biological protection. As stackable fabric moves forward, then using a third extruder 680 may be added a third type of polymer 681, protection from harmful influences, such as fire or heat dissipating polymer. As will be obvious to experts in the art, such a process can continue with so many additional extruders want to give all the desired properties, protects against harmful effects. After adding all the desired polymer layers of the composite fabric is then heated and compressed by the device 682 lamination. Final canvas 684, protecting against many types of harmful effects, and then wound on a bobbin 690 for normal storage and use.

On Fig shows the process of creation of a separate polymer film that protects from the harmful effects that should not be attached to the cloth or other material. Like processes on Fig-17 this process of creating a protective film preferably begins by making a suitable polymer mixture 732 in the hopper 734 extruder 730. For the fabrication protects against radiation film of this polymer mixture 732 preferably consists of a polymer, one or more protecting from radiation material is in and any suitable additives. When the hopper 734 sends polymer mixture in the extruder 730, the polymer mixture is heated to a viscous liquid state and mixed with supplied screw drive 736 of the extruder. When supplied with a drive screw 736 of the extruder pushes the polymer mixture from the extruder 730, at the end of the extruder plate 738 with slit produces film 740 protect from radiation polymer, which is placed on the conveyor belt 742 and cool. Conveyor belt 742 preferably has a floor made of polished metal or Teflon®to prevent sticking of the film to the conveyor belt 742. To speed up the cooling process can be used with a fan, blower or cooling device (not shown). When the protective film 740 is sufficiently cooled, it can be wound on the bobbin end 744 for normal storage. The final reel 744 film, providing protection from harmful influences, can then be used for any of a wide variety of applications set forth in the present description, including clothing, tents, covers, Wallpapers, cladding material, external cladding houses, foundations of houses, etc.

On Fig shows variations of the process illustrated in Fig. Like the process TIG process Fig starts downloading polymerases 732 in the hopper 734 extruder 730. When the hopper 734 sends polymer mixture in the extruder 730, the polymer mixture is again heated and stirred provided with a drive screw 736 of the extruder. However, at this time, the polymer mixture is preferably heated to the consistency of paste, and not to a viscous liquid state. When supplied with a drive screw 736 of the extruder pushes the polymer mixture 748 of the extruder 730, at the end of the extruder 738 plate with slit again produces film protects against radiation polymer 748, which is placed on a conveyor belt 742. At that time, when pasty film 748 is on the conveyor belt 742, it is directed through flatting rollers 750, 752, which simultaneously heats and compresses viscous film 748. During this process of flattening the polymer molecule can normally dry out, forming a cross-link to form a longer molecular chains, which are in the form of a more durable material. After passing flatting rollers 750, 752 final film 754 pull the winding drums 755, 756, and then preferably wound on the bobbin end 758 for normal storage and further use.

On Fig shows an improved version of the process Fig, which can be used to create a separate film, capable of providing many types of protection the s from the harmful effects. Like the process TIG process Fig involves the use of the extruder 730 for heating and mixing the polymer mixture 732 to a paste-like film 748. In a preferred embodiment, such a pasty film 748 is a polymer having protecting against radiation properties. As in the process Fig, such pasty film 748 directed through flatting rollers 750, 752, which are simultaneously heated and compressed pasty film 748. After passing through flatting rollers 750, 752 film 754 pull the winding drums 755, 756, 758 and advance to the second set of flatting rollers 850, 852. In the second set flatting rollers film 754 combine with the second film 810, made by the second extruder 800. As before, the second extruder 800 preferably produces film 810 with another type of protection from harmful influences, such as chemical, biological protection, protection from fire or heat. In the second set flatting rollers both films, 754, 810 is heated and compressed together. Then the composite film 854 pull using the second set of reels 854, 855, 858 winding and preferably is wound on the bobbin end 870 for normal storage and further use.

The above-described processes for making paintings and films protect against the harmful impact is s, dealing with polymer mixtures. However, at least in the context of giving protection from radiation, such polymers are not always needed. For example, protection from radiation can be attached to many types of fibers, including satin and paper impregnation or immersion of the paintings in a highly concentrated solution protects against radiation materials such as barium sulfate, or the reagents used to create protection from radiation material, such as barium chloride and sulfuric acid. In the case of barium sulfate such solution can mainly be 1 - or 2-molar aqueous solution of the precipitate of barium sulphate (although other concentrations may also work). After the precipitate of barium sulphate is completely saturate the canvas (for example, by impregnation throughout the night), the canvas can be removed from a solution of barium sulfate and dried. Drying can also be performed using a drying lamp or microwave installation. Because barium sulfate is able to delay radiation, the impregnated fabric barium sulphate provides the ability to delay radiation, while providing breathability.

To improve the efficiency of the impregnation process can be advantageously used various additives. Such additives may include adhesives, fixer and/or emulsifiers to enhance adhesion and/or with whom umenia solution protects against radiation material. For example, in the previously mentioned solution of barium sulfate may be added to the adhesive, such as the Arabian gum or guar gum for thickening of the solution and to increase the adhesion of barium sulfate to the canvas. Alternatively, the fabric may be added to the adhesive and not the solution of barium sulfate. Pre-treated fabric may then be impregnated with a solution of barium sulfate or immersed in it.

Additionally for impregnation or immersion in a pre-prepared solution containing protects against radiation material, protects against radiation materials of the present invention can also be introduced into the canvas with the use of alternative technologies. Where protection from radiation material is presented in the form of particles in solution (for example, in the form of sediment), one of the alternative technologies is the choice of fabric with pores that are smaller than the particles protects against radiation material, but larger than the solvent (e.g., water or alcohol)used for opaque to radiation of a solution. Then opaque to radiation solution can be passed through the canvas so that the canvas can work as a filter to filter opaque to radiation particles flowing when this is m solvent. In the case of an aqueous solution containing the precipitate of barium sulfate in the pore size of the filter should be of the order of 2 microns and comply with the pore size of Whatman 5. Similarly, the solution is opaque to radiation particles can be sprayed onto the canvas. Again, after a sufficient impregnation of the fabric protects against radiation material, it can then be dried and used for making clothes or another type of product.

In another embodiment, not containing polymer of radiation protection can be created in a reaction chamber with solutions interacting with each other reagents on each side, but the fabric is placed in the middle. In the case of opaque to radiation compounds of barium sulfate, such reagents may be barium chloride and sulfuric acid, respectively. In this example, barium sulphate, because of the natural affinity of barium chloride with sulfuric acid will occur chemical reaction between barium chloride and sulfuric acid, which will leave a precipitate of barium sulfate on the canvas.

In the following an alternative embodiment, not containing polymer of radiation protection, the canvas can be created with one of the reagents included in the canvas (for example, either a connection or a free radical), and then exposed to another reagent with the building of the resulting opaque to radiation treatment. Again, in the case of opaque to radiation compounds of barium sulfate canvas can be previously created with barium or sulfate, as part of the band, and then exposed to another connection for the creation of barium sulfate impregnation.

In the above recitals, the present invention is disclosed with reference to certain preferred embodiments of and ways. However, specialists in the art it is obvious that various modifications and changes may be made without departure from the essence and scope of the present invention, as set forth in the accompanying claims. For example, several preferred embodiments relate to the creation of protective clothing. However, specialists in the art it is known that protection against the harmful effects of radiation, chemical substances, biological agents, metal shells and fire necessary in many circumstances. For example, the type of plasticized protective cloths described in the application of the present invention, can be used as a facing material for vehicles, for x-ray machines, x-ray rooms or cabins. In addition, protects against radiation canvas or other materials this is subramania can also be formed into pouches or bags to protect sensitive materials (for example, the film, electronics) from damage. Because the toxicity of lead is a real factor, protects against radiation materials of the present invention can also be used instead of lead in many modern applications, including solder, used for printed circuit boards. As another example, opaque to radiation materials of the present invention can be finely ground and mixed with latex or paint based on oil. These paints to keep protect from radiation materials in well-mixed form so that they do not fall in the precipitate from the solution, emulsion or suspension may be added emulsifiers, binding agents or suspendresume agents. By adding such protection from radiation materials can be painted or covered with protection against radiation any surface to provide protection against hazards of radiation.

Specialists in the art it will be obvious that the principles and methods described in this patent application are applicable to any area where there is a danger of radiation, hazardous chemicals, infectious biological agents, metal shells or fire.
