270D Hollow Core Polypropylene Filament

Advanced Hollow Fiber for Filtration and Absorption270D Hollow Core Polypropylene Filament is a specialized hollow‑fiber material designed for high‑efficiency filtration, oil absorption, and sediment removal. The hollow core provides a large specific surface area, high dirt‑holding capacity, and rapid wicking action. With a denier of 270 and a tensile strength of 4.5‑5.0 g/denier, the filament offers robust mechanical integrity 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 base polymer, High-Strength Polypropylene Yarn,…
