PP/Absorbent cotton fiber yarn wound around the core support cartridge filter (SP/SE/SG)

This kind of filter cartridges consist of a continuous fibre yarn, which is wound around a fixed core support.  This resulting yarn-structure forms the filter layer with a corresponding layer thickness and depth-filter effect.  Due to the use of various wondering techniques, different thickness of yarn and tractive force during winding, the filter cartridges can be produced with a variety of fine filter rations.
