420D Polypropylene Filament Yarn Industrial Grade

Durable Yarn for Heavy‑Duty Textiles420D Polypropylene Filament Yarn Industrial Grade is a high‑tenacity, fully drawn yarn designed for conveyor belts, outdoor furniture, parachute webbing, and industrial strapping. With a denier of 420 and a tensile strength of 5.8‑6.1 g/denier, it provides excellent break resistance, good abrasion durability, and UV stability. The yarn is chemically inert, moisture‑proof, and suitable for continuous outdoor exposure. Manufacturing ProcessThe yarn is produced using advanced Synthetic Fiber Manufacturing techniques, including melt spinning, multi‑stage drawing, and precision heat setting. It can be twisted into Polypropylene Sewing Thread for heavy‑duty bag closing or upholstery. When woven or braided, it forms PP Strapping and Woven Tape for load securing and packaging. The base material, High-Strength Polypropylene Yarn, guarantees consistent tensile properties and controlled elongation (18‑22% at break). For lightweight nonwoven applications, the f…
