Polyester Staple Fiber (PSF) is a synthetic fiber made from PET (Polyethylene Terephthalate), widely used in textiles, non-woven fabrics, and industrial applications. It is available in virgin and recycled forms, offering excellent durability, resilience, and moisture resistance. PSF comes in various deniers and cut lengths, making it suitable for spinning, filling materials (pillows, cushions, quilts), automotive interiors, insulation, and geotextiles. It can be solid, hollow, siliconized, or non-siliconized, depending on application needs. Lightweight, hypoallergenic, and cost-effective, PSF is a versatile fiber used across multiple industries.
