Hollow polyester staple fiber is a type of synthetic fiber. It is a short polyester fiber with a hollow structure inside.
“Staple” refers to fibers with segmented lengths, as opposed to continuous filaments. Common lengths available on the market include 32mm, 51mm, and 64mm. Daxin offers 51mm and 64mm hollow PSF.
| Hollow Conjugated PSF | Hollow PSF (Non-Conjugated) | |
| Structure | Hollow + Conjugated | Hollow structure only |
| Fill-Power | High | Medium |
| Elasticity | Excellent | Moderate |
| Thermal Insulation | Higher | Medium |
| Hand Feel | Softer, fluffier, closer to down-like feel | More ordinary feel, lower loft |
| Anti-Clumping | Strong | Average |
| Color Consistency / Odor | High consistency when using virgin material | More variation if using recycled material |
| Advantages | Superior softness, higher loft, long-lasting fluffiness | Cost-effective, suitable for large-scale basic filling needs |
| Limitations | Higher cost; more sensitive to raw material quality | Lower comfort and resilience; may flatten faster |
| Applications | Premium pillows, comforters, down alternatives, hotel bedding | General bedding, nonwoven fabrics, insulation, industrial filling |
From the table, we can see that hollow conjugated fibers outperform hollow fibers in terms of properties, while hollow fibers offer a higher cost-performance ratio.
Therefore, Daxin's recommendation is:
If you prioritize loftiness, resilience, and long-term resistance to flattening, such as in the production of high-end pillows, quilts, toys, or garment fillings. ☞ Hollow Conjugated Fibers
If performance requirements are less stringent and you focus more on cost and mass-market product positioning, ☞ Hollow PSF. They are perfectly adequate for manufacturing ordinary pillow inserts, standard cushions, or general fillings.
