摘要

In order to develop efficient and low-cost hot gas filtration medium, composite filters were prepared with PTFE fabric as the substrate, and mixing of OPAN fiber and PPS fibers as functional layers. The fiber entanglement was evaluated via image analysis, and some other characteristics, such as tensile properties, pore size, thermal stability, and filtration performance were also discussed. The results showed that with increasing ratio of PPS fibers, the fiber entanglement, breaking strength, thermal stability, and filtration efficiency increase, while the pore size decreases. Mixing with 40% weight PPS fiber leads to the filtration efficiency of the composite filter increasing from 64.68 to 94.68% for removing particles with a diameter of 2.5 mu m.
