PTFE polyester needle felt membrane filter bag: Why has it become a new choice for industrial dust removal?

PTFE polyester needle felt membrane filter bags have achieved product innovation from filtration efficiency to service life in the field of industrial dust removal through the combination of material and process innovation. Compared with traditional filter bags, its core advantages are reflected in the following aspects:

1. Innovation of filtration mode: from deep filtration to accurate interception
Traditional filter bags rely on the filtration mechanism of fiber gaps, and dust is easily embedded in the pores of the base cloth, resulting in increased resistance and difficulty in cleaning. The PTFE polyester needle felt membrane filter bag uses the coating technology to composite polytetrafluoroethylene (PTFE) microporous membrane on the surface of the polyester base cloth, which improves the initial filtration efficiency and reduces the burden for subsequent work.

3. Improved durability
PTFE coating gives the filter bag good stability. The PTFE polyester needle felt membrane filter bag has a medium high temperature resistance grade, instantaneous temperature resistance up to 130°C, medium acid and alkali resistance, and good wear resistance. It is a commonly used type of felt filter material.

4. Multifunctional adaptability
Through the flexible combination of surface treatment processes (such as singeing, calendering, PTFE impregnation), the filter bag can be subjected to different surface treatments according to different working conditions.
