Pulp fluffing and testing of fluff 

Growing interest in fluff pulp is driven by the global shift toward more sustainable absorbent materials across packaging, hygiene, and specialty applications. As industries look for ways to reduce or replace traditional absorbents that rely on superabsorbent polymers (SAPs), fluff pulp offers a renewable, biodegradable alternative with strong liquid‑handling performance. It can fully or partially substitute SAPs in moisture‑management solutions such as food pads, packaging liners, and other absorbent structures.

We provide pulp fluffing services along with comprehensive testing and analysis of fluff properties, ensuring optimized absorption performance and consistent quality tailored to your application needs.

Pulp fluffing

Our Buffalo W‑6‑H hammer mill enables efficient defibration of pulp sheets into clean, uniform fluff with excellent fiber opening. Through controlled hammer milling, the unit separates fibers consistently, minimizing shives and delivering stable specific volume and absorption properties. This process ensures reliable fluff quality suited for absorbent packaging, hygiene products, and specialty applications. We offer hammer mill fluffing, either as a stand‑alone service or combined with our full range of fluff analyses to optimize performance and material consistency.

Fluff Testing

Fluff testing ensures that cellulose materials used in absorbent products meet the highest standards for performance and consistency.

 

Our laboratory performs the following key analyses:

Air‑laid fluff pad forming

The air‑laid fluff pad former produces uniform fluff pads for subsequent testing of absorption properties and specific volume.

Knot Content

Our MTS Nit Counter measures the level of fiber bundles in fluff. High-quality fluff should contain minimal fiber bundles to ensure smooth processing and reliable absorbency characteristics.

Absorption Time

This test shows how quickly the fluff can take up liquid. A short absorption time ensures effective moisture control and reduced risk of leakage. This test reflects the material’s responsiveness under real-use conditions.

 

Absorption Capacity

Absorption capacity evaluates how much liquid the fluff can retain relative to its weight. This parameter is essential for products that require reliable performance over extended periods. High absorption capacity ensures better fluid management, dryness, and increased product efficiency even under heavy usage.

 

Specific Volume

Specific volume describes the bulk and openness of the fluff, which influences softness, fluid distribution, and overall product performance.
