ELCellulose: grade, tree species and fibre length
The cellulose of an absorbent core is not ordinary paper. It is a fluff pulp whose fibre, species and defibring make the softness and speed of the product.
Virgin fibre, first grade
We use pure first-grade cellulose, in virgin fibre. An absorbent core accepts neither recycled fibre nor a second grade: the cleanliness of the fibre, its whiteness without elemental chlorine and its regularity condition the hygiene of the product and the consistency of its absorption.
Our cellulose suppliers hold the FSC, PEFC and SFI forest certifications. The fibre comes from renewed, responsibly managed forests.
Pine or eucalyptus: fibre length
Softwoods from the southern United States, pine first, give long fibres that form an airy, resilient mat: liquid moves through it fast. Eucalyptus gives short, finer fibres that form a dense, soft mat. The choice depends on the function: a night core wants circulation, a thin pad wants density.
We match the species, and therefore the fibre length, to what each product has to do.
Fluff grade: defibring and softness
Pulp makers grade fluff by its defibring energy, that is how easily the machine separates the fibres, and by the softness of the resulting mat. A fluff that is too hard leaves knots and an uneven core; one that is too soft packs down. We specify the grade for each line, then check mat formation in production.
Part of the fibre is treated to blend intimately with the superabsorbent: this homogeneous blend avoids dry areas and saturated areas.
Pure first-grade cellulose, virgin fibre, species and fibre length chosen per product, fluff grade specified and checked at defibring.
- Virgin fibre, never a second grade in an absorbent core.
- Long fibre for circulation, short fibre for density.
- Defibring is checked in production.
These pages describe materials and test methods in general terms. The exact characteristics of each product are on its technical sheet; they evolve with our laboratory work.
