Articles are described, including fabrics and film layers, which can protect against multiple hazards, including: radiation, chemicals, biological agents, metal projectiles and fire hazards. In some embodiments, the fabrics and films of the present invention are used to produce clothing that has protection against multiple hazards and superior heat dissipating properties. A radiation protective compound is preferably created by mixing a radiopaque material, such as barium, bismuth, tungsten or its compounds, with a powder polymer, a pellet polymer, or a liquid solution, an emulsion or a suspension of a polymer in solvent or in water. The liquefied polymeric films (626, 636) of the two extruders (622, 632) are preferably combined as they are sandwiched between two sheets or fabric or other material (590, 592), such as the polymeric protective films or the fabrics used for chemical protective clothing, biological protective clothing, bulletproof vests or flame retardant clothing. The principles of the present invention can also be applied to a wide range of other items, including surgical hoods, hospital gowns, gloves, patient gowns, divisions, coverages, bed breaks, ponchos, uniforms, work suits, tents, probes, envelopes, bags, wallpaper, linings, dry stone walls, sheets for house wall linings, house foundations, house roofs, etc. |
