Polyester Staple Fiber (PSF) is one of the most widely used synthetic fibers in the global textile and nonwoven industries. It is a man-made fiber produced through a chemical polymerization process using polyester raw materials. Thanks to its stable physical properties, excellent processing performance, and cost efficiency, PSF is extensively applied in apparel, home textiles, filling materials, nonwovens, and various industrial applications.

Polyester Staple Fiber is primarily manufactured from PTA (Purified Terephthalic Acid) and MEG (Mono Ethylene Glycol). Under high temperature and high pressure, these two raw materials undergo a polymerization reaction to form molten PET (Polyethylene Terephthalate).

The molten polymer is then processed through melt spinning, cooling, drawing, crimping, and cutting to produce short fibers with specific lengths and fineness. Unlike polyester filament yarns, PSF is cut into short lengths—typically ranging from 32 mm to 64 mm—making it suitable for spinning systems similar to natural fibers such as cotton.

PSF has become a core material in modern textile and industrial manufacturing due to the following advantages:

• High tensile strength and durability – suitable for frequent-use textiles

• Excellent dimensional stability – resistant to shrinkage and deformation

• Strong chemical resistance – performs well against acids, alkalis, and solvents

• Low moisture absorption – dries quickly and resists mildew

• Good recyclability – can be produced from recycled PET bottles (rPSF)

These characteristics make PSF a reliable and versatile fiber across a wide range of applications.

Note: Actual specifications may vary depending on end-use requirements such as spinning grade, filling grade, or nonwoven grade.

1. Virgin Polyester Staple Fiber

   Produced from new PTA and MEG, virgin PSF offers consistent quality and superior performance. It is commonly used in high-end textiles and industrial fabrics.

2. Recycled Polyester Staple Fiber (rPSF)

   Manufactured from recycled PET bottle flakes, rPSF supports sustainability and circular economy initiatives. It is widely used in filling materials, nonwoven fabrics, and automotive interiors.

3. Hollow Polyester Staple Fiber

   Hollow PSF features an internal cavity structure, providing excellent bulkiness, elasticity, and thermal insulation. It is commonly used in pillows, quilts, and comforters.

4. Functional Polyester Staple Fiber

   This category includes flame-retardant, low-melting, anti-bacterial, and other modified PSF products designed to meet specific safety or industrial requirements.

Due to its versatility, PSF is used across numerous industries:

• Textiles and Apparel: Blended with cotton or viscose to improve strength, wrinkle resistance, and durability

• Home Textiles: Bedding, curtains, carpets, and upholstery

• Filling Materials: Pillows, quilts, cushions, and toys

• Nonwoven Fabrics: Filtration materials, geotextiles, hygiene products

• Automotive and Industrial Uses: Interior linings, insulation, and sound-absorbing materials

As the global textile and manufacturing industries continue to evolve toward high performance and sustainability, Polyester Staple Fiber remains a fundamental raw material with long-term growth potential. Whether virgin or recycled, PSF offers a balanced combination of performance, cost efficiency, and environmental benefits. Its mature supply chain and broad application range ensure that PSF will continue to play a vital role in modern industrial production for years to come.
