Product type
Polyester Staple Fiber (PSF) is a synthetic fiber made from polyethylene terephthalate (PET), a polymer derived from petroleum. It is produced through a process of spinning and cutting long strands of polyester into shorter fibers, typically ranging from 1.5 to 6 inches in length. PSF is known for its durability, resistance to wrinkling, and ability to retain its shape, making it a popular choice in various textile applications.
| Material | Polyethylene terephthalate (PET) |
| Fiber length | 1.5 to 6 inches |
| Denier range | 1.5 to 15 denier |
| Color | White, black, and dyed options available |
| Crimp type | Crimped or non-crimped |
| Applications | Used in filling, insulation, and non-woven fabrics |
When selecting Polyester Staple Fiber, buyers should consider the desired fiber length, denier, and crimp type based on their specific application. It's also important to specify any color requirements and whether the fiber needs to meet certain industry standards or certifications. Quantities should be clearly stated to ensure accurate pricing and availability.
