Frequently Asked Questions

What is Polyester Staple Fiber (PSF)?

PSF is a synthetic fiber made from polyethylene terephthalate (PET), cut into short lengths. It is widely used in spinning, nonwovens, filling materials, and industrial applications due to its strength, durability, and recyclability.

Do you offer recycled PSF?

Yes, we produce 100% recycled PSF using post-consumer PET bottle flakes. Our recycled fibers meet high purity and performance standards for automotive, textile, and nonwoven industries.

Can I get custom fiber specifications?

Absolutely. We offer customization in fineness (1.2D–15D), length (32mm–102mm), color (dope-dyed or spun-dyed), and functional properties like flame resistance, low melt, or anti-static.

What certifications do you have?

Our factory follows strict quality control procedures. While specific certifications depend on product lines, we comply with international standards for fiber performance and safety.
