| The polypropylene fiber is great for acid proof, alkali proof, and great anti- abrasion (second only to the polyamide fiber). Polypropylene staple fiber is short, and hairy after being spun. While Polypropylene fiber is long, and the filament yarn is smooth, so the fabric made of filament yarn has larger tenacity than the fabric made of staple yarn, as well as greater air permeability. Filter fabric made of staple yarn has hair on the surface, so it is better than filter fabric made of filament yarn for dust collection and pressure filtration. While the fabric made of filament yarn has smooth surface and high air permeability, so it is suitable for liquid filtration. We have successfully equipped many filter presses in various industries with our polypropylene filter fabric. |
