However, it is harmful to health. With the man-made fiber industry. A variety of flame-retardant heat-resistant fibers, cellulose fibers such as flame retardant, flame retardant polypropylene fiber, aramid fiber, phenolic, carbon fluoride,<a href="http://www.edhardyoutlet.net" target="_blank" class="postlink">Ed Hardy outlet</a>, carbon fiber, glass fiber and metal fiber and other applications. It has successfully designed a number of new high-tech thermal protective clothing. Depending on the application requirements, thermal protective clothing can be divided into the following categories: (1) radiant heat protective clothing. Strong reflective surface of textile materials can be better reflected radiant heat. Increase the radiation rate of the textile fabric can be coated with polished metal film, such as aluminum coated with gold coating. Metallized fabric about 90% of heat radiation can be reflected, absorbed the rest of the fabric, fabric to avoid the selection at high temperature under 601,998 in February easy to melt, adhesion, softening of the fiber. In the 1500 ~ 3000 ~ F under high radiation environment. Metal fabric can be flame retardant fiber, fiber, aramid fiber, phenolic, glass fiber and carbon fiber. (2) molten metal splash protective clothing. When the molten iron and aluminum metal splashed on the low-temperature thermoplastic fabric will adhere to the fabric. Lead to high heat flux through the fabric causing serious burns. Therefore chosen fiber must consider the following factors: carbonization, melting, heat transfer, droplet, flame retardant, etc., used the best material for protective clothing such as partial oxidation of PAN and aramid yarn. (3) heat protective clothing. Thermal conductivity and thickness of the fabric used in protective clothing, density, thermal conductivity, specific volume, the fabric softening temperature. According to heat transfer conditions,<a href="http://www.tiffany-schmuck.org" target="_blank" class="postlink">tiffany schmuck</a>, metal casting plant with 100% H cellulose fiber and Kevlar fabric effect is not ideal, but the fabric containing PBI fiber is better. Inorganic coated glass fiber material of Taiwan with good results. (4) thermal convection protective clothing. For the fire service. Firemen in the fire during the exposure to hot air, so the outer fabric and inner lining clothing material application to heat and flame retardant fabrics. Now commonly used outer fabric blend of aramid and PBI materials, cushioning material available breathable and comfortable wear of PTFE fiber membrane (GoreTex). (5) flame protective clothing. To avoid the risk of wearer exposure to pain and burn under fire hazards to consider when designing fire-retardant protective clothing, thermal protection and so on. Limiting oxygen index (LOI) high is important, not lively heat (density, heat, thermal conductivity) is also very important. Avoid using easily melting, softening and adhesion of the fiber. Found from a variety of coated fabrics, 40% PBI and 60% Kevlar blend fabric has a good and efficient performance. 2.5 Chemical protective clothing Chemical protective clothing and gas environment can cut off the body. Effectively prevent the gas damage. In accordance with its material properties can be divided into the following two: (1) of protective clothing impervious. 4O years on the early development of the butyl rubber protective clothing, are still used. It has good anti-virus performance,<a href="http://www.montblancpenss.com" target="_blank" class="postlink">Mont Blanc pens</a>, airtight, impede diffusion of water vapor on the skin, but a serious impact on human evaporative cooling,<a href="http://www.uggbotass.com" target="_blank" class="postlink">ugg botas</a>, can not long wear, and heavy, physical exertion, only for the chemical, biological, radiological contamination of personnel more serious regional work use. (2) permeability of protective clothing. For human use in the chemical war against mustard gas and other toxic gases protection. Usually also used for pesticide spraying protection. Permeability of protective clothing using double-layer structure, the outer function is to undertake a variety of wear intensity and spread of the venom attached; the inner function is adsorbed venom, poison gas, and prevent its adoption in order to avoid invasion and skin. Lining materials for non-woven fabric. Subject, including fluoride and carbon coating. As if the physical absorption of carbon, rather than some additional chemicals chemistry. So it is a broad-spectrum anti-virus function. Plus non-woven fabric is a fiber distribution network structure messy than the traditional weaving warp and weft cross the small pores and tortuous, venom and poison gas through the difficulties, it is an ideal protective lining material. To sum up. Actual use. Individual performance and multi-functional protective problems to coordinate a comprehensive, Lang A variety of protective clothing to prevent harmful factors, more difficult to achieve this requirement, but both can still do some. With the further development of science and technology, special features clothing increasingly widespread development and application, special clothing functionality will continue to be strengthened. 3</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/Avalanche/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
