The Influence of Matching Flameresistant Materials on the Thermal Protective Performance of Firefighter Uniform
Firefighter uniform made of various flame retardant materials is put as the object. Analyzing the thermal protective performance of different composite structures covering outer fabrics, lagging materials and comfortable layer materials, discuss the best combination of supporting structures. Adoption flash fire simulation, verify the integrated prevention ability of firefighter uniform. The matching of different levels has a significant impact on the thermal protective performance, first the outer layer, then comfortable layer and thermal protective coating. Although inherent fire resistant fiber for the main material of the outer fabric has better durability and thermal protective performance, the fire might experience obvious contraction which leads to embrittlements. For insulation flocculus, the ratio of aramid fiber 1313 and aramid fiber 1414 at 9:1 has excellent thermal insulation. For comfortable layer, inherent fire resistant fiber has no notable effect on the clothing’s overall thermal protection performance; the polysulfonamide fiber is a relative better choice.
