630D Hollow Polypropylene Filament

High‑Performance Hollow Fiber for Liquid Filtration630D Hollow Polypropylene Filament is a robust hollow‑fiber material engineered for demanding filtration applications including depth filters, wastewater treatment, industrial cartridges, and sediment removal. With a denier of 630 and a tensile strength of 4.8‑5.2 g/denier, it provides high mechanical durability, excellent dirt‑holding capacity, and efficient backwashing. The hollow core offers a large specific surface area while maintaining low pressure drop and high flow rates. Manufacturing ProcessThe filament is produced using advanced Synthetic Fiber Manufacturing techniques, including melt spinning through a specialized spinneret that creates a continuous hollow channel. For filter bag assembly, the fiber can be twisted into Polypropylene Sewing Thread to seam filter components. When woven into a fabric, it shares chemical resistance with PP Strapping and Woven Tape, though the hollow geometry is unique to filtration media. The b…
