Key Takeaways
- Fluff pulp is a wood-pulp-based absorbent material made from cellulose fibers, used in traditional diaper cores to absorb and distribute liquid quickly.
- How it works: Fluff pulp is made by defibering softwood pulp into fluffy cellulose fibers.
- Traditional diaper cores blend fluff pulp with SAP granules for fast wicking plus high retention
- Myth: More fluff means more absorbency. Fluff absorbs fast but holds little; SAP holds much more — balance matters
How Fluff Pulp Works
Fluff pulp is made by defibering softwood pulp into fluffy cellulose fibers. In a diaper core, fluff absorbs liquid quickly and channels it across the core, while SAP locks it in. The balance of fluff and SAP affects absorption speed, softness and cost. High-GSM fluff is used in heavy-duty adult incontinence products.
Examples and Applications
- Traditional diaper cores blend fluff pulp with SAP granules for fast wicking plus high retention
- Airlaid paper compresses fluff pulp for thin sanitary pad cores
Fluff Pulp vs. Related Terms
| Term | What it is | Key difference |
|---|---|---|
| SAP | Fluff Pulp | Fluff wicks fast but holds little; SAP holds hundreds of times its weight but absorbs slower alone |
Limitations and Common Misconceptions
- Myth: More fluff means more absorbency. Fluff absorbs fast but holds little; SAP holds much more — balance matters
- Myth: All fluff pulp is bleached with chlorine. TCF (totally chlorine free) and ECF options exist for low-allergen products
What is fluff pulp made from?
Softwood wood pulp defibered into fluffy cellulose fibers. Some is chlorine-free (TCF/ECF).
Why is fluff pulp still used if SAP holds more?
Fluff absorbs quickly and keeps the core soft and flexible; SAP alone absorbs slowly and can gel-block.
