Is Cupro / Bemberg Vegan? Material Facts & Alternatives

Vegan status: Vegan

Also known as: Bemberg (brand name), Cuprammonium rayon, Cupro silk

Origin

Plant-derived — made from cotton linter (the very short fibres left on cotton seeds after the longer fibres are removed), dissolved in a copper-ammonia solution and regenerated into fibre.

Environmental impact

Rating: medium. Uses cotton linter waste (a byproduct), which is positive. However, the copper-ammonia dissolution process requires careful management of copper waste. Bemberg (the leading brand, produced by Asahi Kasei, Japan) claims a closed-loop process recovering most chemicals and metals used.

Durability

Good. Drapes beautifully, soft, breathable, and hypoallergenic. Biodegradable at end of life.

Common uses

Garment linings, blouses, dresses. Often used as a silk substitute in luxury linings.

Notes

Cupro is marketed as a vegan silk alternative with superior breathability compared to synthetic linings. It is often the lining fabric in luxury fashion garments. Bemberg is the dominant commercial producer. Relatively niche but gaining attention as a vegan alternative to silk linings in tailored garments.
