Description

Various Hazardous Protective Clothing and its Manufacturing Method {MULTIPLE HAZARD PROCTECTION ARTICLES AND METHODS FOR MAKING THEM}

The present invention relates to garments comprising layers of fabrics, mixtures and films that can protect against life-threatening hazards such as radiation, chemicals, biologics, metal projectiles and fires. In some embodiments, the fabrics and films of the present invention are used to make garments with good heat dissipation and protection against various hazards.

Today there are many forms of danger that can result in serious injury or even death. These risks include radiation, corrosive or toxic chemicals, infectious biologics, metal projectiles such as bullets or debris, and fires. Many of these risks have been known for many years, and in the light of recent terrorist activities, including attacks by terrorists provoked at the World Trade Center on September 11, 2001, risks become more urgent and more difficult to stop. .

Many of the risks facing today are thought to be used locally only in places such as nuclear power plants, fuel processing plants, nuclear waste stations, x-ray scanners, chemical refineries and biological laboratories. Nevertheless, these risks extend to any place where the growth of terrorism can be seen with the naked eye. In the case of nuclear radiation, the explosion of a portable nuclear bomb, such as a "pollution bomb", which cooperates with nuclear waste material, can cause fatal radiation to spread through metropolitan areas. Likewise, the release of communicable biologics is no longer limited to biological research laboratories, but can occur anywhere a terrorist can choose to release such infectious biologics.

In addition to the need to protect against life-threatening hazards over a wide range of areas, it is also necessary to simultaneously protect against various forms of risk. For example, while nuclear power plants can clearly predict the dangers of nuclear power, the emergence of terrorism now means that potentially deadly biological or chemical agents can be released from the same nuclear power plant. Similarly, while biological research laboratories try to prevent the release of lethal biologics, the explosion of “pollution bombs” by terrorists near such laboratories will pose a risk of serious radiation exposure. For this reason, simply considering it as the most predictable form of risk no longer provides effective protection.

Today there is a need for a method that provides effective and economical protection against various forms of risk. In the past, for example, clothing has been created to provide protection against special threats. In the case of radiation, there was previously a harmful effect of radiation through the manufacture of radiopaque protective clothing. There have been a number of attempts to mitigate the spread. In particular, these radiopaque protective garments are made of stiff materials such as lead or rubber embedded in any other heavy metal that can block radiation. Examples of lead embedded in radiopaque garments are found in Holland U.S. Patent 3,052,799, Whittaker U.S. Patent 3,883,749, Leguillon U.S. Patent 3,045,121, Via U.S. Patent 3,569,713 and Still U.S. Patent 5,038,047. Can be. In other cases, the radiopaque material is incorporated into the polymer film, such as Shah US Pat. No. 5,245,195 and Lagace US Pat. No. 6,153,666.

Clothing is also made for special threats from metal projectiles such as bullets and debris. For example, Borgese US Pat. No. 4,989,266 and Stone US Pat. No. 5,331,683 disclose two types of ballistic vests.

In addition, fabrics have been developed to provide resistance from corrosive or toxic chemicals. Examples of such chemical protective fabrics can be found on the Internet. These chemical protective fabrics are polyethylene fabrics such as Tyvek® from Dupont, polypropylene fabrics such as Kleenguard® from Kimberly Clark or Proshield® from Kappler, TyChem® from Dupont or HazardGard I (from Kimberly Clark) Plastic laminated fabrics such as Trademark) and microporous film-based fabrics such as NexGen ™ from DuPont or Proshield 2 ™ from Kappler. These chemical protective fabrics provide protection, especially against biologics.

While these conventional fabrics, blends and garments provide protection against the special threats they are designed to counter, they have a number of drawbacks. For example, lead embedded in conventional garments provides good protection against the harmful effects of radiation, while these conventional garments are often heavy, stiff, expensive and bulky. These garments are often uncomfortable, cumbersome and limited. Also, lead is, of course, a toxic substance that must be handled with great care and not inadvertently exposed. In addition, these conventional radiation protective garments require sterilization and radiation removal because they are particularly bulky and expensive and are toxic when exposed after each use.

Similarly, bulletproof vests and conventional body armor tend to have poor heat dissipation. These bulletproof vests and body armor can be inconvenient to wear in hot weather, so the user will choose to have no protective gear over the risk of overheating. This poor heat dissipation also has another disadvantage for military use. When a soldier's body temperature is allowed to endure in a vest or body armor, the soldier may have a so-called "heat signature" in other areas of the soldier's body where heat may be released. This uneven "heat trajectory" allows for easy exposure by enemy heat detection equipment. For survival purposes on a highly technical battlefield, it is better to have a uniform "heat trajectory" by quickly dissipating heat through the soldier's body.

In addition, clothing designed to be effective for one risk may not be effective for another. For example, conventional radiation protective clothing will probably not be effective at stopping bullets. Conversely, conventional bulletproof vests or body armor will not be effective at stopping radiation.

The present invention includes a fabric and a film layer, and relates to a garment that can protect against a variety of hazards, including radiation, chemicals, biologics, metal projectiles and fire hazards. In some embodiments, the fabrics and films of the present invention are used to make garments having various risk protection and good heat dissipation. In other embodiments, the protective fabric or film may be used to make ponchos, protective tents, nuclear probe rods, wallpaper, house siding, roofing materials, composite house foundations or commercial aircraft cabin liners, airport scanners, food throwers or x-ray rooms. Can be. In addition, the materials of the present invention may be incorporated into paints or coatings and applied to a wide range of surfaces.

The radiation protection mixture is preferably made by mixing a radiation protection material such as barium, bismuth, tungsten or mixtures thereof with a liquid polymer, a particulate polymer or a liquid solution, emulsion or suspension of the polymer in a solvent or water. The polymer is not limited but may be selected from a wide variety of plastics including polyurethanes, polyamides, polyvinyl chloride, polyvinyl alcohols, natural latexes, polyethylene, polypropylene, ethylene vinyl acetate and polyates. The radiation protective polymerization mixture is then preferably bonded to one or more fabric layers.

Next, other forms of danger shields can be combined with radiation shields. For example, the radiopaque polymer mixture may be laminated onto one or more fabrics commercially available to provide protection against hazardous chemicals, biologics, metal projectiles or fires. Commercially available fabrics include polyethylene fabrics such as Tyvek® from Dupont, polypropylene fabrics such as Kleenguard® from Kimberly Clark or Proshield® from Kappler, TyChem® from Dupont or HazardGard I from Kimberly Clark Plastic laminated fabrics, such as trademark) and microporous film-based fabrics, such as NexGen® from DuPont or Proshield 2® from Kappler, carbon spherical blends such as Saratoga® from Blucher GmbH, Kevlar® from DuPont Or aramids such as Nomex (trade name).

In addition, films that can provide protection against hazardous chemicals, biologics, agents, or metal projectiles may be laminated or deposited on a radiation protective fabric or the film of the present invention. This additional film can be formed of various polymeric materials such as polyethylene, polypropylene, polyurethane, neoprene, polytetrafluoroethylin (Teflon®), Kapton®, Mylar® or mixtures thereof.

If moisture or a soldier's thermal trajectory is concerned, heat dissipation mixtures such as copper, silver, aluminum gold, beryllium, tungsten, magnesium, calcium, carbon, molybdenum, and / or zinc may be used to supply one or more fabric layers. It may be added to the radioprotective polymer mixture beforehand. In addition, polymers, heat dissipating layers can be specially made and attached to radiation protective fabrics.

The radiation protective fabric may be inserted into a vest or body armor alone or in combination with other layers (eg, chemical protection, heat dissipation). In particular, the bulletproof vest and body armor consist of aramid and / or layers of polyethylene fabric sewn together. To add radiation protection to such vests or body armor, a layer of radiation protective fabric may be laminated on or sewn between the aramid and / or polyethylene fiber layers. Chemical and biological protective agents may also be added by sewing or laminating chemical protective films and aramid and / or polyethylene kevlar fabrics.

Using similar principles, known fire retardants such as Aramid Nomex® or Kevlar® fabrics manufactured by Dupont have been used to create garments that provide protection against many forms of life-threatening hazards. By sewing or laminating, it may be combined with bulletproof, radiation protective, chemical and biological resistant materials and / or heat dissipating fabric layers of the present invention. Such garments can be characterized as "all-round" protective clothing. In addition, the principle of the present invention is a surgical hood, gown, gloves, patient clothing, poncho, partition, cover, parachute, uniform, work clothes, tent, jacket, bag, wallpaper, liner, drywall, house siding, It is also widely applicable to other garments, including house foundations, radiation probes, etc. In addition, transparent articles with radiopaque properties, such as impregnated eyewear, may be attached or inserted into the protective suit of the present invention.

Clothing may be provided comprising layers of fabrics, mixtures and films that can protect against life-threatening hazards such as radiation, chemicals, biologics, metal projectiles and fires.

For full surface protection, the full body suit 10 is preferably a one piece jump suit covering all parts of the body. Elastic bands 12 and 14 may be used around the arms and legs to make the chute closer to the arms and legs. Optionally, the gloves 16, boots 18 and hood 20 are separated into separate parts to overlap the rest of the jumpsuit so that the skin is not exposed at all. The full body chute 10 also includes hook and loop fasteners or zipper flaps 28 to allow the user to easily enter the full body chute.

The transparent eye protector 24 is preferably provided on the full body suit 10 to protect the face. For convenience, eye protector 24 may be hinged by something such as corner rivet 26 to allow the user to flip up and down. Optionally, the eye protector may be stand-alone equipment such as safety glass (not shown). In order to provide radiation protection, the eye protector 24 is preferably provided with lead or pseudo radiation protective glass.

In FIG. 2, the intermediate polymer layer 60 comprising radiation protection materials 62, 64, 66, 68 in addition to the polymer 52 is sandwiched between two layers of fibers or other materials 34, 36. The outer fibers or other materials 34 and 36 are preferably flat and can be bent. For example, it may be an elastic nonwoven fabric such as polypropylene, polyethylene, aramid fibers, rayon or mixtures thereof. Optionally, the outer fabric or other material may be a fabric such as clothing, or may be another kind of flat and flexible material such as paper or film.

As radiation protective materials, barium sulfide, tungsten and bismuth are preferred for use in the present invention as compared to lead because they are light, inexpensive and have little inherent risk. Other radiation protection materials may also be used, but are not limited to such. Such materials include barium, other barium compounds (eg barium chloride), tungsten compounds (eg tungsten carbide and tungsten oxide), bismuth compounds, tantalum, tantalum compounds, titanium, titanium compounds, ditrizoates Meglumine Injection USP (trade name sold by Nycomed Corporation under the tradename HYPAQUE), Acetrizoate Sodium, Boron, Boric Acid, Boron Oxide, Boron Salt, Other Boron Compounds, Beryllium, Beryllium Compounds, Bunamiodyl Sodium, Diatrizoate Sodium, Ethiodized Oil, Iobenzamic Acid, Iomic Acid, Iothemic Acid, Iodipamide, Iodixanol, Iodide Oil, Iodo-Alpionic Acid, Ortho (o) -Iodohyporate Sodium , Iodophthalein Sodium, Iodopyracet, Ioglymic Acid, Iohexol, Iomeglymic Acid, Iopamidol, Iofanoic Acid, Iopenentol, Iopenodilate, Iphenoxylate, I Offromide, ioponic acid, iopydol, iopydone, italamic acid, iotrolan, ioversol, ioxaglynic acid, iosilane, ipodate, meglumine acetrizate, meglumine ditrizoate Methiodal sodium, methrizamide, methrizoic acid, phenobutiodyl, pentethiotalein sodium, propyliodone, sodium iodomethamate, sozodolic acid, thorium oxide and tripanoate sodium. These radiopaque materials include Fisher Scientific, PO Box 4829, Norcross, Georgia 30091 (tel: 1-800-766-7000), Aldrich Chemical company, PO Box 2060, Milwaukee, Wisconsin (tel: 1-800-558-9160) and Sigma, PO Box 14508, St. Louis, Missouri 63178. In order to obtain the best protection against radiation, smaller sized radiation protective materials such as ultrafine sizes are preferred. Nevertheless, the additional cost of purchasing these small sized particles must be considered against the importance of the additional protective performance achieved. Those skilled in the art will appreciate that other radiation protection materials that bind the same metal are interchangeable with the materials listed above.

In the radiation protective synthetic fabric 50 of FIG. 2, the radiation protective material is embedded in the polymerization mixture 60. The polymerization mixture 60 preferably comprises a polymer 52, one or more radiation protective materials 62, 64, 66, 68 and one or more additives. The polymer 52 may be selected from a wide range of plastics including polyurethanes, polyamides, polyvinyl chloride, polyvinyl alcohol, natural latex, polyethylene, polypropylene, ethylene vinyl acetate (EVA) and polyester, It is not limited to this. The additives are usually chemicals to improve flexibility, strength, durability or other properties of the final product and / or chemicals to ensure that the polymerization mixture has adequate uniformity and homogeneity. These additives can be, where appropriate, plasticizers (eg, epoxy soybean oil, ethylene glycol, propylene glycol, etc.), emulsifiers, surfactants, suspensions, level promoters, dry promoters, flow enhancers, and the like. One of ordinary skill in the plastic processing arts will be familiar with the selection and use of such additives.

These various polymerization mixture component ratios can be varied. In general, the higher the ratio of reflective protective material used, the greater the contribution to radiation protection performance. Nevertheless, if the proportion of the radioprotective material is too high, it becomes brittle and easily brittle when the polymerization mixture is dried and cooled. The inventors have found that over 50% by weight of the polymerization mixture is barium sulfide, tungsten, bismuth or other radiation protective material, with the remainder of the mixture being mostly polymer.

In the fabric and full body suit sold under the trade name DEMRON radiation protection compound by Radiation Shield Technologies, Inc. of Miami, FL, the inventors typically comprise about 85% by weight of the radiation protection material and about 15% by weight of the polymer. A polymerization mixture for radiation protective compounds is used. Current preferred combinations of radiation protection materials used in DEMRON polymerization mixtures are tungsten 75%, barium sulfide 20% and bismuth 5%. Current preferred polymers used in the DEMRON polymerization mixtures are polyvinyl acetate (EVA) and polyethylene. Current preferred outer fabric layers used in DEMRON polymerization mixtures are woven and nonwoven fabrics, such as DuPont's Tyvek and Tychem flashspun polyethylene fibers. The use of Tyvek and / or Tychem woven fabrics for DEMRON has the advantage of adding chemical and biologic protective properties to the radiation protection properties of DEMRON.

Like our commercial DEMRON product, the intermediate polymeric layer 60 shown in FIG. 2 includes several radiation protection materials 62, 64, 66, 68. These radiation protection materials 62, 64, 66, 68 may be, for example, barium compound 62, tungsten compound 64, bismuth compound 66 and iodine compound 68. By using a plurality of different radiation protection materials, radiation protection products can be more effective than similar products with a single radiation protection material in shielding other forms of radiation. For example, some radiation protection materials may be more effective at shielding beta particles, while others will be more effective at shielding gamma rays. By using two radiation protective materials in the radiation protective fabric or other materials of the present invention, the article has a better ability to shield both beta particles and gamma rays.

In this regard, it would be appropriate to consider the use of lead as one of such radiation protection materials for such hybrid products, or more generally, for the plastic products disclosed herein. Because of potential health risks, lead may be undesirable as the other radiation protection materials described above, but nevertheless, lead may play a role in plastic radiation protection mixtures or other plastic film products.

In areas where it is important for a radiation protective suit or product to have a respiratory function like a surgical mask or where a full body suit is used in a particularly hot and humid environment, two radiation protection layers 110 and 112 as described above may be used. As shown in Fig. 3, holes may be formed and alternately arranged. As shown in FIG. 3, the two radiation protection layers 110, 112 are separated by a gap 114. To prevent the gap 114 from collapsing, the gap 114 may be filled with a porous or nonwoven fabric, such as a garment (not shown). Both radiation protection layers 110, 112 are perforated to form a pattern of holes 116, 118, 120. By offsetting the holes 116, 118, 120 in the heads 110, 112 as shown in FIG. 3, the radiation particles moving in a nearly straight line are caught in at least one of the two layers, while the air turns around the obstacle. Can be passed.

Likewise, the above-mentioned radiation protection material or aluminum is formed in the fiber and woven into a garment or entangled with a conventional garment material such as a garment to provide the garment's flexibility and the radiation protection of metallic lead garments. The radiation protective material may also be installed in various transparent plastics or glasses to form a radiopaque transparent eye protector 24, for example as shown in FIG. In another alternative embodiment, a perforated or non-perforated sheet of pure radiation protective material such as aluminum may be inserted into the product to enhance the impermeable quality.

4 shows a second way of increasing radiation protection through a specific multilayer structure 80. Each layer 81, 82, 83 of this multilayer article 80 has a different thickness. One thickness of layer 81 may stop radiation 84 having a particular wavelength characteristic, while radiation 86 of another wavelength characteristic may pass directly through. Nevertheless, by backing up the first layer 81 with additional layers of different thicknesses, the possibility of stopping different types of radiation, regardless of their wavelength characteristics, is increased. As another example, the layers 81, 82, 83 can be formed of other radiation protection materials. For example, barium, tungsten and / or bismuth radiation protection materials have been found by the inventors to provide cost effective protection for alpha and beta particles, but not sufficiently for neutrons. To provide better protection against neutrons, the inventors have found that films that are tightly filled with boron and / or beryllium radiation protection materials are more effective. Such boron and / or beryllium films preferably have about 50% by weight of radiation protective fabric and about 50% by weight of polymer and additives. In order to provide cost effective protection against alpha, beta and neutron particles, an effective approach is to use a polymer layer comprising barium, tungsten and / or bismuth compounds 81 to a polymer layer having boron and / or beryllium compounds 82. Will be combined with As will be appreciated by those of ordinary skill in the art, the different radiation protection materials 62, 64, 66, 68 shown in FIG. 2 may have different thicknesses 81, shown in FIG. 82, 83) allows synergies to occur to form radiation protection products that provide maximum radiation protection for a given weight and thickness.

5A, 5B and 6 show that not only the full body suit 10 shown in FIG. 1 but also various garments can be formed with the hazard protection film and fibers of the present invention. FIG. 5A shows a medical apron 130 formed, for example, of the hazard protection film and / or fibers of the present invention. The illustrated apron 130 covers the user's chest 132, upper arm 134 and neck 136 with a hazard protection film and fibers, such as the radiation protection fibers described above. As will be appreciated by those skilled in the art, all parts of the body may be covered by this apron 130 to provide a certain level of protection. Wrap around strap 138 is formed on the lower waist portion of the apron 130 to make the apron close to the user's body. This wrap around strap 138 preferably includes hook or loop fasteners (not shown) to securely secure the ends of the straps 139 to each other.

FIG. 5B is a rear view of the medical apron 130 of FIG. 5A. The rear view shows how the wrap around strap 138 intersects behind the back so that the ends meet at the front of the apron 130. The rear view also shows an upper body connecting strap 140 that firmly secures the apron to the upper body of the user. Also, hook and loop fasteners (not shown) are preferably used to removably fasten at least one end of the upper body connecting strap 140 to the medical apron 130. As shown in Figure 5B, the opening 142 is located on the back side of the medical apron 130 to be easily worn on the user's body. The opening 142 is formed under the assumption that the front side of the user's back is exposed to danger. Of course, if the user's back is at risk, this portion 142 should not be open.

6 shows that the hazard protection film and fabric of the present invention may be formed into a two-piece chute 150. Such a two-piece suit includes a pants 152, a jacket 154 and a hood 158, which consist of the hazard protection film and fabric of the present invention. Belt 156 is used to securely fasten jacket 154 to pants 152. In addition, gas mask 159 may be used to prevent inhalation of toxic gases. Compared to the full body chute 10 of FIG. 1, the two-piece chute 150 is suitable for military use where flexibility is required. For example, on hot days, soldiers may have trousers 152 and belts 156 with jackets 154, hoods 158, and gas masks 159 close, if there is a potential chemical, radiation, or biological threat. You can also wear only) to keep cool.

7 to 10 show that the hazard protection materials of the present invention are not limited to fibers and garments. 7 shows, for example, how a radiation protective material can be applied to a conventional retaining wall 120. In such a case, the radiation protection material of the present invention, such as barium sulfide, tungsten or bismuth, may be inserted between the two layers of cardboard 124 and 126 122 after mixing with the gypsum commonly used for retaining walls.

8 and 9 show that the hazard protection materials of the present invention may be used in the construction sector. 8 shows a cross section of a wall 160 for use in a house or other building, for example. This wall 160 may include a retaining wall 162, a heat insulator 166, a sheath 164, an external tubing 168, and a housing wrap 169. The risk protection of the present invention can be installed in these wall layers. Installation of a radiation shield on a conventional retaining wall has been described in FIG. Radiation protective materials, such as barium sulfide, tungsten or bismuth, may be mixed with the thermally insulating material 166 or spray bonded. The housing wrap 169 used in construction is often a polymer film, such as DuPont Tyvek. As with the inventor's DEMRON described above, radiation shields can be added to flashspun polyethylene Tyvek fabrics by laminating the radiation protective polymerization mixture on the Tyvek fabrics. By using similar lamination or other adhesive techniques, radiation shields can be added to materials commonly used in sheath 164 and outer tubing 168.

9 shows how a hazard shield is added to the foundation 170 of a house or other building. This foundation consists of steel concrete 174 that supports the floor 172 and the wall 160 of the house or building. To improve radiation protection for materials such as radon coming from under the ground, radiation protection materials such as barium sulfide, tungsten compounds or bismuth may be mixed into the steel concrete 174 used for the foundation 170. Optionally, the film or fabric layer 176 of the present invention may be inserted between the steel concrete 174 and the bottom 172 of the foundation 170. The same principle can be used so that the roof of a house or building (not shown) is protected from radiation penetration of the sun. In the case of a roof, the radiation protective material may be mixed with the outer roof material (e.g., ceramic tiles), or laminated on the outer roof material (e.g. shingles), and the hazard protection film or fabric shown in FIG. 176 may be inserted between the exterior roof material and the interior roof structure.

Figure 10 shows how the synthetic radiation protection compounds of the present invention can form castings. The casting of FIG. 10 is a radiometric probe 180 that can be inserted into the ground to help find the place of accumulation of radioactive material. The radiation measurement probe 180 includes a slidable outer sleeve 182, an inner housing 184, a detection window 188, and a flange 186 for stopping the outer sleeve 182. So far, the problem with these radiation measuring probes is that they leave very much extra radiation through the outer sleeve 182 and inner housing 184 to reliably read whether the metered radiation is from the direction of the detection window 188. It is hard to do. To solve this problem, the outer sleeve 182, inner housing 184 and flange 186 may be formed of a polymerization mixture that cooperates with the radiation protection material as described above. The higher the proportion of radioprotectant added to the mixture, the better the protection against radiation, but if the proportion of radioactive material is too high, the polymerisation mixture will become brittle and dry easily upon drying and cooling. The ratio of polymer and radiation protection material should be chosen to produce a robust probe when calculated through a casting process with a sufficient amount of radiation protection material to prevent background radiation. By using the radiation protective polymerization mixture of the present invention in the radiation measuring probe 180 of FIG. 10, the detected radiation will be more reliable than any radiation passing through the rest of the probe 180.

Referring to FIG. 11, synthetic fabric cross section 200 is shown to provide protection against lethal hazards from radiation, such as toxic chemicals, infectious biologicals, fire and metal injection hazards. As part of the multi-risk protective synthetic fabric, the three layers of synthetic fabric described above have a radiation protective polymerization mixture 34, 36, 60 (FIG. 2). Additional layers 210, 220, 230 are added to these three layers 34, 36, 60 to provide protection against other hazards. For example, a non-porous chemical protective layer 210 and / or 220 can be added to the three radiation protective layers 34, 36, 60. This non-porous chemical layer may be a polymer film 210 laminated to three radiation protection layers 34, 36, 60, and a chemical sewn or adhered to the radiation protection layers 34, 36, 60. It may also be a protective fabric 220.

Such chemical protective layers 210, 220 may be formed of known chemical protective polymers and / or fabrics. For example, one known chemical protective fabric is a flashspun polyethylene fabric sold under the trade name Tyvek from DuPont, a polypropylene fabric such as Kleenguard of Kimberly Clark, Kappler's Proshield 1, Lakeland's Safeguard 76, Sontara and Kimberley Clark of DuPont. Cellulose based fabrics such as Prevail and nonwoven fabrics such as woven blended polyethylene with propylene. Similar nonwovens include plastic films laminated on both sides of the nonwoven, such as DuPont's TyChem series fabrics, Kimberly Clark's HazardGard I and II fabrics, Kappler's CPF and Responder series fabrics, and ILC Dover's Ready 1 fabrics. . These nonwovens are joined by sewing or adhering the three radiation protection layers 34, 36, 60 to each other on the fabric.

Chemical protection is also enhanced by polyvinyl chloride and / or chlorinated polyethylene films such as ILC Dover's Chemturion. These films may be laminated or extruded on the three radiation protection layers 34, 36, 60 of the present invention.

Another chemical protective layer is a polymer film with fine pores deposited on Gore-tax or polypropylene-based fabrics such as NexGen from DuPont, Kleengard Ultra from Kimberly Clark, Lakeland's Micro-Max and Kappler's Proshiled 2. Chemical protection performance may be provided by materials having an absorbent layer such as carbon / fabric sold by Blucher GmbH and Lanx. Another type of chemical protective fabric is a woven fabric in which rubber or plastic is coated on one or both sides. These applied chemical protective fabrics include polyvinyl chloride and nylon compounds, polyurethane / nylon compounds, neoprene / aramid compounds, butyl / nylon compounds, chlorinated polyethylene / nylon compounds, polytetrafluoroethylene (ie, Teflon) / glass fiber composites. And chlorobutyl / aramid composites.

Since the chemical protective layers 210 and 220 are preferably non-porous, protection against infectious biological agents will also be possible.

Although the fabric of FIG. 11 adds a chemical protection layer 210, 220 to the three radiation protection layers 34, 36, 60 to provide a wide range of protection, additional or optional layers 210, 220. 230 may be selected to prevent further risks or to promote heat dissipation. For example, if the chemical protective layer 210 is a plastic laminate, the layer 220 of FIG. 11 may be another woven or nonwoven layer, and the layer 230 is made of a Nomex flame retardant aramid fabric made by DuPont. It may be a flame retardant layer, such as a losing layer. Other types of flame retardant materials include a combination of Nomex and Kevlar aramid fabrics sold by Southern Mills, a combination of melamine resins and aramid fabrics, a combination of polytetrafluoroethylene (ie Teflon) and aramid fabrics, and a combination of rayon and arimid fabrics. , Combinations of polybenzimidazole and aramid fabrics, combinations of polyphenylenezoisoxazole and aramid fabrics, combinations of polyimide and arimid fabrics, and Mylar plastic films. Optionally, layer 230 may be a ballistic layer made of ballistic aramid and / or polyethylene fabric.

Optionally, it may be desirable to form layer 230 with a heat dissipating material. One way of forming such a heat dissipating layer is to mix compounds with high thermal conductivity such as silver, copper, gold, aluminum, beryllium, calcium, tungsten, magnesium, zinc, iron, nickel, molybdenum, carbon and / or tin. As such, the polymer is mixed in the same manner as the radiation protective material is mixed with the polymer to form the radiation protective layer 60.

Although a six-layer hazard protection fabric 200 is shown in FIG. 11, those skilled in the art will appreciate that multilayer hazard protection fibers may be produced in more than six layers or less. For example, the woven or nonwoven layers 34, 36, 220 shown in FIG. 11 may be omitted. Other hazard protection or heat dissipating layers may be combined together in a single layer. For example, although it has been found that the radiation protection layer 60 of the present invention provides excellent heat dissipation properties by itself, this heat dissipation property is not limited to the mixture of radiopaque materials in the radiation protection layer 60 with silver, copper. And / or by adding a steel thermal conductor such as aluminum.

12, the vest 300 is shown to have additional risk protection characteristics. Most ballistic vests 300 are conventional designs similar to those shown in Borgese, U.S. Patent No. 4,989,266, the contents of which are incorporated by reference. Bulletproof protection is first provided by layers of polyethylene fabric 314 and / or aramid fabric 316. Commercially available polyethylene fabrics used for bulletproof vests include Honeywell's Spectra series ultra high molecular weight polyethylene fabrics and Honeywell's Spectraguard ultra high molecular weight polyethylene fabrics, which also include glass fibers. Commercially available aramid fabrics used for bulletproof vests include DuPont's Kevlar series aramid fabrics and Akzo's Twaron series aramid fabrics. In a preferred embodiment, the bulletproof vest has one or more aramid fabrics 316 sandwiched between polyethylene fabrics 314. In order to obtain better performance on bullets and debris, a larger number of aramid fabric layers 314 and / or polyethylene fabrics 316 are produced. Additional strength can be produced by wrapping the ballistic material several times at 90 degrees to each other and wrapping it between the thermally fired layers. Ceramics and plates can be added to provide a high level of protection. Bulletproof vest 300 of Figure 7 is preferably fixed to each other by the cloth insertion casing (312).

To add additional risk protection to the ballistic vest 300 of FIG. 12, additional layers 320 shown in FIGS. 2, 4 and 11 may be inserted. In one embodiment, the additional layer 320 may be the synthetic radiation protection layers 50, 80 of FIGS. 2 and 4. By adding such radiation protection layers 50 and 80 to the bulletproof vest, the bulletproof vest can secure not only bullets and debris but also protection against radiation. Likewise, the multilayer fabric of FIG. 11 can be used to improve fire, chemical and / or biological protection. Radiation Protection In one case, an additional layer 320 located adjacent to the user's body may be required to take advantage of the good heat dissipation properties of the radiation protection layers 50 and 80 of the present invention. Conversely, for fabrics that enhance fire, chemical and / or biological protection, a layer may be added on top of the bulletproof vest to prevent contaminants from penetrating into the vest 300.

13-20 illustrate other fabrication techniques that can be used to create the hazard protection fabric of the present invention. FIG. 13 illustrates a manufacturing technique particularly suitable for mass production of the radiopaque fabric or other flat and flexible material of FIG. 2, for example, used in garments and other products. 13 proceeds with one or more rolls 430, 432 of the fabric or other flat and bendable material 34, 36 to which the polymerization mixture is applied. Polymeric nonwovens, such as polypropylene, polyethylene, aramid, rayon, or other mixtures thereof, are suitable for this process, as these polymeric fabrics bind well with liquid polymeric mixtures and in some cases provide intrinsic risk protection performance. Alternatively, this process may be performed using a woven fabric, such as a garment, and other flat and flexible materials, such as paper or film. Corona treatment may be applied to the fabric or other material by one or more corona treaters 438, 439 to enhance the ability of the fabric or other material 34, 36 to bond with the polymerization mixture.

In this process, the radiation protective liquid polymerization mixture is applied to one side of the nonwoven or other material using the applicator 440. The applicator 440 includes a roller 442 to roll the liquid polymerization mixture on a side of the nonwoven or other material 34 into a thin film (eg, preferably 0.1-20 mm thick).

After the application unit 440, the thin layer of polymer mixture is partially dried before the polymerized fibers 444 are preferably passed through the hot air oven 446 to the lamination unit 448. In the lamination unit 448, the coated fibers 444 are preferably combined with a second sheet of material 36 such as fibers under heat and pressure to produce a sandwich shaped radiation protective fiber 50. Material, such as sandwich shaped radiation protective fibers, may be perforated and / or embossed in the perforation / embossing unit 452 if desired. Typically, the finished radiation protection product is wound into a final roll 454 to be shipped to a suitable place for use in assembled clothing or other articles. Two layers of material such as fibers 34 and 36 are shown in this example of FIG. 4, while the polymer mixture is applied to a single sheet of material such as fibers 34 (ie, a sandwich with an open front). do.

FIG. 14 illustrates an improved version of the process illustrated in FIG. 13 that can produce fibers with multiple protections at risk. As shown in FIG. 13, two fiber rolls 430, 432 and an application unit 440 may be used to produce a sandwich type radiation protection fiber of the type shown in FIG. 2. To reinforce protection from bullets or debris, the two fiber rolls 430, 432 can be rolls of bullet protection aramid and / or polyethylene fibers. To give an additional type of protection, a third fiber roll 470 and a second application unit 476 can be added to the process. The fibers in roll 470 may typically be woven equally as rolls 430, 432, woven or are bullet resistant fibers. The second application unit 476 preferably imparts a liquid polymer mixture with various non-radiation type hazard protection devices such as chemical, biological or fireproof. As an alternative, the liquid polymer mixture from the second application unit 476 can deposit a heat dissipation layer having a strong thermal conductor, such as silver, copper or aluminum embedded in the polymer mixture.

In the lamination unit 484, the sandwich shaped radiation protection fiber is combined with an additional hazard protection fibrous layer 480 to produce a synthetic fiber 490 having multiple forms of hazard protection. Synthetic fiber 490 may be perforated and / or embossed within perforation / embossing unit 452, if desired. Nevertheless, when the additional layers confer chemical and / or biological protection, this perforation / embossing step should be avoided.

Returning to FIG. 15, a second general type process for producing the hazard resistant fibers of the present invention is shown. In the process of FIG. 15, the polymer mixture element 570 is placed into the first injector 572. For protection from radiation, the polymer mixture 460 preferably comprises a polymer, one or more radiation blocking materials and one or more adhesives. In such a processor, this polymer mixture element may enter the hopper 571 in solid form. As the hopper 571 feeds the polymer mixture element 570 to the first injector 572, the polymer mixture elements are preferably heated in a viscous liquid phase and through the rotational action of the motor-operated injector screw 463. Are mixed together. As this motorized injector screw 573 pushes the polymer mixture elements out of the first injector 572, the combination of the perforated plate and the rotary cutter 574 cuts the current polymer mixture into pellets 575. . This pellet 575 is preferably inserted into the hopper 576 of the second injection molding machine 577. Again, the polymer mixture is melted through screws 578 which are heated and motorized. At this time, when the polymer mixture elements are pushed out of the injector 577, the slot plate at the end of the second injector 579 is used to inject a thin film of the molten polymer mixture 600. Such thin film 600 may advantageously be 0.1 to 20 millimeters thick. In order to simplify this process step, this thin film 600 may be produced by the first injection machine 572 alone. Nevertheless, by stacking the second injector 577, there is more possibility that the polymer mixture will not be uniformly mixed before being injected.

As in the processes shown in FIGS. 13 and 14, the molten polymer mixture in the FIG. 15 process is preferably sandwiched between two sheets of material, such as fibers 590, 592. As before, the fiber sheets are preferably not wound from the fiber rolls 594, 596. Corota treaters 596 and 598 may again be used to enhance the binding process. In this case, a thin film of molten polymer mixture 600 is applied simultaneously between both fiber sheets and other materials 590, 592. When a thin film of molten polymer mixture 600 is inserted between two sheets 590, 592, the two sheets 590, 592 are preferably compressed and heated between the rollers of the stacking unit 602. , When required, perforated and / or embossed in the perforation / embossing unit 604. For convenient storage, a finished material 606, such as finished radiation protective fiber, may be wound into the final roll 608.

16 and 17 show an improved version of the process illustrated in FIG. 15 that can produce a fiber with multiple risk protection devices. Like the process of FIG. 15, FIG. 16 may include an injection machine 622 to produce a radiation protective film 626. This radiation protective film can be produced by placing the polymer mixture elements 620 in the hopper 621. As mentioned above, the polymer mixture preferably comprises a polymer, one or more radiation blocking materials and one or more adhesives. Hopper 621 feeds polymer mixture elements 620 to injector 622. In the injection machine 622, the polymer mixture elements are mixed together via a rotational action of the injection machine screw 623, which is preferably heated in a viscous liquid phase and operated by a motor. Once the polymer mixture elements are pushed out of the injector 622, the slotted plate 624 at the end of the injector is used to inject a thin film of molten polymer mixture 626. If desired, the above-described injector similar to the injector 572 of FIG. 15 may be used to further ensure that the polymer mixture placed into the hopper 621 of the injector 622 is uniformly mixed.

Unlike the FIG. 15 process, the second injector 632 of the FIG. 16 process is disposed in parallel with the first injector 622 to simultaneously produce a second film 636 that is combined with the radiation resistant first film 626. do. Preferably, the membrane 636 produced by the second injector 632 provides a different type of hazard protection than the membrane 626 produced by the first injector 622. For example, the first injection molding machine 622 may be advantageously used to produce the radiation protection film 626, while the second injection molding machine 632 may be used to produce the compensating chemical, biological or fire protection film 636. It can be used advantageously. To produce this compensated membrane 636, various types of polymer mixtures are loaded into the hopper 631, heated to liquid form, and mixed together through the rotational action of the motorized injection machine screw 633. . As the motorized injection machine screw 633 pushes the elements of these various polymer mixtures from the injection machine 632, the slotted plate 634 at the end of the injection machine 632 draws a thin film of molten polymer material 636. Used to inject.

The molten polymer films 626, 636 from the two injectors 622, 632 are joined as sandwiched between two sheets 590, 592, preferably of a material such as fiber. As mentioned above, the fiber sheets are preferably not wound from the fiber rolls 594, 596. Corona treaters 596 and 598 may again be used to enhance the binding process. When the composite film 638 is inserted between the two sheets 590 and 592, the two sheets 590 and 592 are preferably compressed and heated between the rollers of the lamination unit 602, preferably, perforated Perforated and / or embossed in / embossing unit 604. For convenient storage, a number of finished anti-risk products 640 may be wound into the final roll 650.

FIG. 17 illustrates how the principles of FIGS. 13-16 can be used to create a fiber having any number of risk protection properties. The process of FIG. 17 begins with a roll of material 656 such as fibers. Sheet 658 is pulled from fiber roll 656 and used as a substrate for depositing a polymer layer from injection machine 660. As one example, sheet 658 may be a bullet or debris protective fiber produced from aramid and / or polyethylene fibers, and polymer layer 661 may be a type of radiation protective polymer mixture described above. As an alternative, the sheet 658 may be a chemical or refractory fiber, such as a tablespoon polyethylene, polyvinyl chloride or polypropylene chemical protective fiber or aramid refractory fiber. Using the second injector 670, a layer of additional hazard protection material, such as a chemical or biological protective polymer layer, may be added to the growth fiber 664. As the growth fibers move forward, a third type of risk preventing polymer 681 may be added using the third injector 680. As will be appreciated by those skilled in the art, this process starts with the number of injectors required to add all of the desired risk protection features. After all of the given polymer layers have been deposited, the synthetic fibers are heated and compressed in the lamination unit 682. The final multiple hazard protection fiber 684 is wound into a roll 690 for convenient storage and use.

Returning to FIG. 18, the process of forming a free stop film of a hazard-free polymer that is not necessary to attach with a material such as fiber is shown. As with the process of Figures 15-17, this protective film process preferably begins by introducing a suitable polymer mixture 732 into the hopper 734 of the injection machine 730. In order to produce a radiation protective film, this polymer mixture 732 preferably consists of a polymer, one or more radiation protective materials and a suitable adhesive. As the hopper 734 feeds the polymer mixture to the injection machine 730, the polymer mixture is heated by a viscous liquid phase and agitated by a motor operated injection screw 736. As the motor-operated injector screw 736 pushes the polymer mixture out of the injector 730, the slotted plate 738 at the end of the injector is deposited on the endless conveyor belt 742 and cooled by a film of radiation protective polymer ( 740 is generated. The endless conveyor belt 742 preferably has a polished metal or Teflon® to protect the film without needing to be attached to the conveyor belt 742. To accelerate the cooling process, a fan, blower or refrigeration unit (not shown) can be used. When the protective film 740 is sufficiently cooled, it can be wound into the final roll 744 for convenient storage. The final roll 744 of the hazard protection film can be used for any number of applications discussed herein, including the manufacture of clothing, tents, envelopes, wallpaper, liners, house side applications, roofing applications, house foundations, and the like. .

FIG. 19 shows a variant of the process shown in FIG. 18. Like the process of FIG. 18, the process of FIG. 19 begins by sending the polymer mixture 732 to the hopper 734 of the injection machine 730. As the hopper 734 feeds the polymer mixture to the injection machine 730, the polymer mixture is heated again and stirred by the injection machine screw 736 operated by a motor. However, at this time, the polymer mixture is preferably heated to a paste hardness rather than a viscous liquid. As the motorized injector screw 736 pushes the polymer mixture 748 out of the injector 730, the slotted plate at the end of the injector 738 again prevents the risk of being deposited on the endless conveyor belt 742. A film of polymer 748 is created. At this time, when the paste film 748 exits the endless conveyor belt 742, it is fed to calender rollers 750, 752 which simultaneously heat and compress the paste film 748. During this calendaring process, polymer molecules typically become cross-polymers to form longer molecular chains, which results in stronger materials. After leaving the calender rollers 750 and 752, the finished film 754 is pulled by the winding rollers 755 and 756 and then preferably wound to the final roller 758 for convenient storage and later use.

FIG. 20 illustrates an improved version of FIG. 19 that can be used to create a free stop membrane that can provide multiple risk protection. Like the process of FIG. 19, the FIG. 20 process includes heating and stirring the polymer mixture 732 with a paste film 748 using an injection machine 730. In a preferred embodiment, this paste film 748 is a polymer having a radiation protection function. As in FIG. 19, this paste film 748 is supplied to calender rollers 750 and 752 which simultaneously heat and compress the paste film 748. After leaving the calender rollers 750, 752, the membrane 754 is pulled by the winding rollers 755, 756, 758 and moves forward to the second combination of calender rollers 850, 852. In a second combination of calender rollers, the membrane 754 is combined with the second membrane 810 produced by the second injection molding machine 800. As mentioned above, the second injector 800 preferably produces a membrane 810 having various types of hazard protection devices, such as chemical, biological, fire or heat dissipation. In a second combination of calender rollers, the two membranes 754, 810 are heated and compressed together. The composite membrane 854 is pulled by the second combination of take-up rollers 854, 855, 858 and is preferably wound onto the final roller 870 for convenient storage and later use.

Processes that are further described to produce hazard resistant fibers and membranes have an associated polymer mixture. Nevertheless, at least some of the imposition of radiation protection such as polymers is not always necessary. For example, a radiation protector may be used by soaking or immersing such fibers in a solution of a high concentration of radiation protective material, such as barium sulfide, or in reagents used to form the radiation protective material, such as barium chloride and sulfuric acid reagents. Or many types of fibers, including paper. In the case of barium sulfide, this solution can advantageously be an aqueous solution of 1 or 2 moles of the barium sulfide catalyst (although other concentrations may work). After the barium sulfide catalyst has fully saturated the fiber (eg, soaked overnight), the fiber may be removed from the barium sulfide solution or dried in error. Drying is possible by using a dry lamp or microwave device. Since barium sulfide can block radiation, saturating barium sulfide with fibers provides the ability to block radiation while allowing porosity.

In order to improve the efficiency of the saturation process, a viscous adhesive may be advantageously used. Such adhesives may include adhesives, adhesives and / or emulsifiers to enhance adhesion or to increase the concentration of a solution of radiation protective material. For example, an adhesive such as Gum Arabic or Guar Gum may be added to the barium sulfide solution described above to increase the concentration of the solution and improve the adhesion of barium sulfide. As an alternative, the adhesive may be added to the fiber instead of the barium sulfide solution. The pretreated fiber is soaked or immersed in the barium sulfide solution.

In addition to soaking or dipping in already prepared solutions comprising the radiation protection material, the radiation protection material of the present invention may be saturated with fibers using other techniques. If the radiation protective material is in particulate form (eg, as a precipitate) in solution, other techniques are smaller than the particles of the radiation blocking material, but larger than solvents (eg, water or alcohol) for use in radiation blocking solutions. Is to choose a fiber with larger pores. The radiation blocking solution may pass through the fiber in a manner that allows the solvent to pass while the fiber acts as a filter to filter the radiation blocking particles. In the case of aqueous solutions containing barium sulfide precipitates, the filter pore size should be on the order of 2 microns and corresponds to the pore size (5) of Whatman. Similarly, the radiation blocking particle solution can be sprayed onto the fibers. Again, the fibers are sufficiently wetted with radiation shielding material, and then dried to assemble into articles such as clothing.

In another polymer-free radiation protection embodiment, a reaction chamber can be created with a solution of compensating reagent on each side with the fibers disposed in between. In the case of barium sulfide radiation blocking compounds, these reagents can be barium chloride and sulfuric acid, respectively. For example, in this barium sulfide, since barium chloride is naturally acclimated to sulfuric acid, a chemical reaction occurs between barium chloride and sulfuric acid, which is left behind the barium sulfide precipitate in the fiber.

In an alternative example of another polymer-free radiation protector, the fiber may be formed (eg, as a compound or free group) with one reagent contained in the fiber and applied to another reagent to produce the resulting radiation blocking saturation. Exposed. Again, in the case of barium sulfide radiation shielding compounds, this fiber may advantageously be formed of barium or sulfides as part of the fiber and exposed to other compounds to produce barium sulfide saturation.

In the foregoing specification, the invention has been described with reference to certain preferred embodiments and methods. However, one of ordinary skill in the art appreciates that various modifications and changes can be made without departing from the broader spirit and scope of the invention as set forth in the appended claims. For example, many preferred embodiments relate to the creation of protective clothing. Nevertheless, those skilled in the art also need protection against radiation, chemical, biological, metal projectiles and fire hazards in many other contexts. For example, the type of plasticized protective fiber described herein can be used, for example, as a liner for vehicles, x-ray injection devices, x-ray rooms, or aircraft cabins. Moreover, materials such as radiation protective fibers of the present invention may be formed with envelopes or porches to prevent damage to the sensing material (eg, photo film, electronics). Because lead poisoning is severe, the radiation protection materials of the present invention can be used to replace lead in many current applications, including lead used in printed circuit boards. As another example, the radiation blocking material of the present invention may be finely ground and mixed with a rubber or oil containing paint. Emulsifiers, binders or suspending agents are added to such paints to allow the radioprotective materials to be well mixed so that they do not precipitate into solution, emulsification or suspension. Through the addition of such radiation protection materials, the radiation protection device can be printed or coated onto any number of surfaces to protect against the danger of radiation.

Those skilled in the art will appreciate that they can be applied in radiation, hazardous chemicals, infectious biologics, metal projectiles or any place where a fire occurs. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense, and the invention is to be limited only by the appended claims.
