Abstrakt: Aimed to expand applications of aramid fiber fabrics and provide a reference for select fibers for filter bags using in high temperature flue gas filtration, properties such as filtration performance, temperature resistance, wear resistance, folding endurance, corrosion resistance and flame retardance of aramid fibre needle punched nonwoven fabrics were measured, in comparison with polyimide fiber needle punched nonwoven fabrics and glass fiber woven fabrics. It is found that aramid fiber fabric exhibits excellent temperature resistance. The tensile strength remains unchanged after thermal treatment under 220 °C for 24 hours. The folding endurance and corrosion resistance are excellent. The filtration performance of fabrics composited with 1 D aramid fibers is excellent while its flame retardance and wear resistance should be improved by PTFE emulsion impregnation.
