Polyester is a broad term for a category of synthetic fibers made from petrochemicals. It refers to the raw fiber or fabric made entirely from polyester polymers. Polyester fibers are strong, durable, resistant to shrinking and stretching, and quick-drying.
Spun Polyester, on the other hand, is a specific type of polyester yarn made by spinning short polyester fibers together, similar to how cotton yarn is made. This spinning process gives spun polyester a texture and feel more like natural fibers, often softer and with better breathability compared to continuous filament polyester yarn.
Key Differences:
| Feature | Polyester | Spun Polyester |
|---|---|---|
| Fiber Type | Can be continuous filament or staple fibers | Made by spinning short polyester fibers (staple fibers) |
| Texture & Feel | Smooth and shiny, less breathable | Softer, more cotton-like feel |
| Breathability | Lower breathability | Higher breathability due to fiber structure |
| Strength & Durability | High strength and durability | Slightly less strong but comfortable |
| Common Uses | Activewear, outdoor gear, industrial fabrics | Apparel, upholstery, blends with cotton |
Summary:
Polyester is a general synthetic fiber category, while spun polyester is a type of polyester yarn made by twisting short fibers together, providing a softer, more natural feel similar to cotton.
