1. What is Polyester Staple Fiber (PSF)?
Polyester Staple Fiber is a synthetic fiber made from polyester polymers, primarily derived from purified terephthalic acid (PTA) and monoethylene glycol (MEG). It is cut into short lengths (staple) and used in various textile and nonwoven applications.2. What are the key properties of Polyester Staple Fiber?
High Strength: Excellent tenacity and durability.Thermal Resistance: Melting point of 250°C - 260°C.
Chemical Resistance: Resistant to acids, alkalis, and most solvents.
Low Moisture Absorption: Moisture regain of 0.4% - 0.6%.
Versatility: Can be customized for specific applications (e.g., flame retardancy, UV resistance).
3. What are the common applications of PSF?
Textiles: Apparel, home textiles, upholstery, and carpets.Nonwovens: Hygiene products, wipes, and medical textiles.
Filling: Pillows, quilts, and cushions.
Industrial: Geotextiles, filtration, and insulation materials.
4. What is the difference between virgin and recycled PSF?
Virgin PSF: Made directly from raw materials (PTA and MEG).Recycled PSF: Produced from post-consumer PET bottles, offering an eco-friendly alternative.
5. What are the available denier and length options?
Denier: Ranges from 0.8D to 15D (common options: 1.2D, 1.4D, 6D).
Length: Standard lengths include 32 mm, 38 mm, and 51 mm, with custom lengths available.
