Fibra de aramida usada em traje de combate a incêndios

Como componente básico da roupa de proteção do bombeiro, os requisitos para desempenho retardador de chama são particularmente importantes. O surgimento da fibra de meta-aramida permitiu a atualização de roupas de combate a incêndios. Permite que os bombeiros eliminem completamente os ternos pesados de combate a incêndios que só têm couro, lã pesada e lona, e obtenham melhorias de desempenho de tecidos e revestimentos.

Atualmente, bombeiro, trajes de combate a incêndios, trajes de incêndio feitos de fibras coloridas de meta-aramida têm sido usados em vários sistemas de combate a incêndios. As fibras coloridas meta-aramida também são equipadas com uniforme de bombeiro florestal da polícia armada.

Devido ao seu excelente desempenho, meta-aramida é amplamente utilizado em metalurgia, construção, construção naval, petróleo, química, silvicultura, proteção contra incêndios, militares e outros campos, e tornou-se a melhor escolha para processar todos os tipos de roupas de proteção especiais.

Firefighters have a heavy load to bear — their turnout gear shouldn’t add to it.  So Aramid fibers help manufacturers create fire resistant liners, outer shells, and accessories that not only stand up to the thermal hazards they may face, but also help them get the job done without getting in the way of mobility.

Unlike other materials and fibers available, gear and accessories made with meta aramid fiber are inherently flame-resistant and won’t melt, drip, or support combustion in the air. And the thermal protection off  is permanent — its superior flame resistance cannot be washed out or worn away. Para aramid helps manufacturers enhance the overall durability and strength of lightweight turnout gear outer-shell-and-thermal-liner systems. It is five times stronger than steel on an equal weight basis, yet is lightweight, comfortable, and thermally protective.

Ambas essas fibras inovadoras são encontradas em cada camada da maioria dos equipamentos de turnout para proteção final:

●A Concha Exterior

Meta aramid and Para aramid fibers are engineered together and sometimes  with other high-temperature fibers to form materials that help stand up to heat, stay strong, and protect the inner components.  Para aramid filament is engineered into premium fabrics to help reduce fabric profile while strengthening fabrics to new levels of performance.  

●A barreira da humidade

Fabrics made of meta aramid fiber and non-wovens help the most trusted and reliable moisture barrier manufacturers provide strong flame-resistant substrates for their liquid-impermeable films.   The moisture barrier helps protect against the intrusion of water, chemicals, and viral agents.  These barriers are also breathable, which allows metabolic heat to escape and helps reduce the overall heat stress during strenuous activities.

●Os forros térmicos

Meta aramid and Para aramid fiber batts and the meta aramid non-wovens are combined with face cloths made with meta aramid and para aramid fiber to help provide durable, flexible, heat-insulating components.  Thermal liners made with multi-layer meta aramid non-wovens are among the thinnest, most flexible, most breathable components on the market. Face cloths using para aramid filament yarns help reduce surface friction, improving overall garment mobility.  Water-wicking or -repellent finishes on individual layers improve moisture management and reduce garment-drying time.
