Polyester Staple Fiber

1. Product Overview

Polyester Staple Fiber (PSF) is a synthetic fiber produced primarily from polyethylene terephthalate (PET) and engineered for consistent performance across textile and industrial applications. It is widely used in spinning, nonwoven fabrics, filling materials, home textiles, automotive interiors, and technical textile products. Its strength, dimensional stability, resilience, and versatility make it a cost-effective alternative to many natural fibers. As a high-volume industrial raw material, PSF supports efficient large-scale manufacturing and dependable global sourcing.
