Spunbonded nonwoven filter cloth for pleated style filter cartridges production
Spun Bonded Filter Cloth
Zonel Filtech developed the Bicomponent polyester (BICO polyester) serial spunbonded filter materials, which with the special designed pattern combined with the 3D spunbonded lapping workmanship to make the spun bonded filter cloth from Zonel Filtech with following properties when compare with the traditional spunbonded filter medias:
1. Good air permeability but with super filter efficiency.
After testing, the result shown that the BICO polyester serial spunbonded filter cloth with the similar weight always can get a better filter efficiency, but the air permeability is more than 90% higher than the traditional spunbonded polyester nonwovens, that’s mean the BICO polyester serial filter cartridge media can handle the much higher air volume but with a much lower resistance in cartridge filter housing under the same filter area basis, that can help to offer a most economical but better filter solution for our end users.
2. High tensile strength.
After testing, the result shown that for the similar weight spunbonded filter cloth, the tensile strength of BICO polyester serial spunbonded filter material is more than 90% higher than the traditional spunbonded filter cloth, that’s mean the A serial filter cartridge media can stand the higher pulse jet purging pressure and not easy to be broken, can get a longer service life.
3. Super stiffness
As usual, for increase the filter area of the filter cartridge, we will pleat the spunbonded filter cloth with certain pleats on the pleating machine, the super stiffness of the spunbonded filter media sure can help to make the filter cartridge always keep a correct shape and get a stable working performance.
4. Higher dust loading
The PET/PET Bicomponent spunbonded filter cloth with 3D construction, much better on the dust loading capacity, can adopt the longer purging time, also not easy to cause secondary dust releasing, increase the service life of the filter cartridges.
The spunbonded filter cloth from Zonel Filtech can design with many finish treatments, such as to be treated with PTFE coating/ PTFE membrane laminated (spun bonded with PTFE membrane), water & oil proof(spun bonded water repellent media), and antistatic by aluminum foil (spun bonded anti-static filter cloth) and so on, the filter fineness from 0.1 micron to 10 micron, filter efficiency more than 99%.
