From a Nonwoven Roll Manufacturer to You
When you lie down on a comfortable mattress, you feel the soft quilted surface, the supportive foam, and the responsive springs underneath. What you don't see is the hidden material that holds it all together.
That material is often polypropylene spunbond nonwoven fabric.
In this article, we'll explore where PP spunbond is used in mattresses and bedding — and why it has become a standard component in modern mattress manufacturing.
A modern mattress is a complex assembly of layers: fabric cover, quilting, foam, fiber pads, spring units, and base support. Spunbond nonwoven appears in several of these layers.
ComponentFunction of Spunbond
| Quilting backing | Supports the quilted top layer, prevents fiber migration |
| Spring wrap | Separates springs from foam, reduces noise and wear |
| Dust cover (bottom) | Protects the mattress interior from dust and moisture |
| Foam encasement | Wraps foam layers, contains dust, prevents yellowing |
| Fiber pad backing | Provides stability to fiberfill layers |
| Border / side panel reinforcement | Adds strength to the mattress edge |
PropertyBenefit
| Lightweight | Doesn't add unnecessary weight to the mattress |
| Strong and tear-resistant | Withstands compression, flexing, and handling |
| Lint-free | No loose fibers inside the mattress |
| Hydrophobic | Repels moisture — prevents mold and musty odors |
| Breathable | Allows air circulation — keeps the mattress fresh |
| Soft and flexible | Doesn't create hard spots or affect comfort |
| Easy to cut and sew | Clean edges, no fraying — efficient production |
| Cost-effective | Lower cost than woven or knitted alternatives |
1. Quilting Backing
The quilted top of a mattress consists of a decorative fabric, a layer of foam or fiberfill, and a backing layer. Spunbond nonwoven is often used as the backing layer — it supports the quilting, prevents fiber migration, and provides a smooth surface for lamination.
2. Spring Wrap / Spring Cover
In innerspring mattresses, the spring unit is covered with a layer of spunbond fabric before foam is applied. This separation layer prevents springs from rubbing against foam, reducing noise and extending mattress life.
3. Dust Cover (Bottom Lining)
The bottom of the mattress is typically covered with a dust cover. Spunbond nonwoven provides a dust-proof, breathable barrier that protects the mattress interior while allowing air circulation.
4. Foam Encasement
Before foam layers are assembled, they are often wrapped in spunbond fabric. This contains foam dust, prevents yellowing, and makes assembly easier.
5. Fiber Pad Backing
Fiberfill pads (polyester or other fibers) are often backed with spunbond fabric to provide stability and prevent fiber migration.
6. Mattress Border / Side Panel Reinforcement
Spunbond fabric is sometimes used in the border or side panel of the mattress to add strength and prevent sagging.
7. Pillow and Bedding Components
Spunbond is also used in pillows, mattress toppers, and other bedding accessories — as a lining, backing, or dust cover.
Our single-layer PP spunbond is naturally hydrophobic — it repels water and moisture.
In mattresses, this is important:
Key distinction: Our single-layer PP spunbond is hydrophobic by default — ideal for mattress dust covers, spring wraps, and foam encasement where moisture resistance is important.
