Materials

What we process, family by family: species, typical fill power, uses and certifications. How we process it, from raw material to certified lot, is onThe process.

The raw material as it is: feather, down cluster, the kapok pod, regenerated P.U.R.E.® and the Flower Down® blend.

The families

Technical data, species and ideal uses of every family processed by Minardi Piume.

Down and feather

Goose and three duck families. Down and feather are a by-product of the food chain, never the reason for farming.

P.U.R.E.® Recycled Down

P.U.R.E.®

Typical FP
~750
Species
Recycled post-consumer down
Ideal uses
Sanitised and reprocessed in our internal recycling department: capacity 1,000,000+ kg/year, 843,000 kg regenerated in 2025.
GRS

Typical FP higher than Pekin at equal down content.

Flower Down®

Flower Down®

Typical FP
~750
Species
Patented down + Kapok blend
Ideal uses
Patented high-FP blend: bedding and outerwear combining down softness with kapok lightness.

Patented Minardi Piume technology.

Kapok & plant fibres

Typical FP
—
Species
Ceiba pentandra and other plant fibres
Ideal uses
The lightest plant fibre in the world: bedding and vegan fillings, botanical alternatives to down.

Typical fill power figures are measured in our own laboratory to the IDFB method, in a conditioned climatic chamber. Figures obtained under other measurement standards are not directly comparable.

Our brands

P.U.R.E.® Recycled Down

P.U.R.E.® Recycled Down

Post-consumer recycled down, GRS certified, sanitised and regenerated in our own recycling department. The name stands for Pure Unique Recycled Eco-down.

Flower Down®

Flower Down®

A patented blend of down and kapok: the loft of down with the lightness of the plant fibre, measured for fill power by a recognised laboratory (below).

Flower Down®, measured

In a fill power test run by an EDFA-recognised laboratory in 2020, Flower Down® reached 750 cu.in against roughly 450 cu.in for polyester measured under the same protocol, in the same test.

Kapok

The plant fibre that lightens the blend grows wild in tropical forests, with no artificial irrigation and no pesticides, and is harvested by hand by local communities.

Not only raw material

Duvets, quilts and pillows leave our bedding atelier finished: the same down, sewn into fabrics we select and test ourselves.
