1. Product Overview
Polyester Staple Fiber (PSF) is a synthetic fiber produced primarily from polyester polymers, widely used across textile, nonwoven, filling, and industrial applications. It delivers consistent fiber performance, dimensional stability, strength, and cost efficiency, making it a dependable alternative to natural fibers in high-volume manufacturing. Its versatility and scalable supply make PSF a strategically important raw material for global textile and industrial manufacturers.
