Nonwoven fabrics for wadding are widely used in products where warmth and cushioning are important, such as quilts, mattresses, sofas, and padded clothing.
The key factor that determines the performance of these wadding nonwovens lies in the type of polyester staple fiber (PSF) used.
In particular, the solid and hollow product groups each have their own advantages and unique features, so the choice varies depending on the application and purpose.
In this article, we will summarize the main fiber product groups suitable for nonwoven fabrics used in wadding.
Fibers for Nonwoven Wadding – Solid Fiber

Solid fibers are general round staple fibers without a hollow structure, and they are widely used in wadding manufacturing.
Denier (fineness): 3D ~ 15D (general purpose)
Cut length: 32 mm, 38 mm, 51 mm, 64 mm (suitable for bedding and furniture wadding)
Material type: Virgin PSF (high-quality, virgin grade), Recycled PSF (recycled, GRS certification available)
Characteristics: Excellent price competitiveness, high versatility, stable physical properties during nonwoven processing, and widely used in bedding, mattresses, sofas, and industrial insulation materials.
Fibers for Nonwoven Wadding – Hollow Fiber

Hollow fibers have an internal void structure that creates an air layer, providing excellent insulation and resilience.
Denier (fineness): 7D ~ 15D and above
Cut length: 32 mm ~ 64 mm
Characteristics: Superior thermal insulation (air-layer effect), high bulkiness and elasticity
Main applications: Winter quilts, padded clothing, premium mattresses
Solid vs. Hollow Comparison
Category | Solid PSF | Hollow PSF |
Structure | Solid, high density | Hollow, with air layer |
Insulation | Normal | Very excellent |
Resilience | Stable and uniform | Superior elasticity and bulkiness |
Cost | Relatively low | Higher manufacturing cost |
Processability | Suitable for all processes such as needle punching and thermal bonding | Requires care during carding and blending |
Main Uses | Bedding, sofas, mattresses, industrial insulation | Padded clothing, winter quilts, premium filling materials |
For nonwoven wadding, both solid and hollow product groups are used, but solid PSF is the most widely applied due to its versatility and cost competitiveness.
On the other hand, hollow PSF has strengths in premium bedding and clothing where insulation and resilience are critical. In addition, with the expansion of the eco-friendly market, demand for GRS-certified recycled PSF continues to grow.
DK FIBER supplies both recycled solid and hollow PSF, and upon customer request, we can provide polyester fibers for wadding nonwovens with GRS TC certification.
