具有良好的耐温、耐氧化、过滤性能，热稳定性极好，在177 °C时收缩率小于1%，偏芳族聚酰胺纤维也是阻燃型纤维。在水泥工业、沥青工业、冶金工业、烟草工业等不含酸碱性介质的环境中，芳纶性能表现非常优异;特别在水泥窑头除尘工艺中应用相当广泛。

Superior product- aramid fiber (MX) dust bag

It has good temperature resistance, oxidation resistance, filtration performance, excellent thermal stability, and the shrinkage rate is less than 1% at 177 °C. Metaaramid fiber is also a flame-retardant fiber. In environments without acidic and alkaline media such as cement industry, asphalt industry, metallurgical industry, and tobacco industry, aramid fiber has excellent performance; it is especially widely used in the dust filtration process of cement kiln heads.
