Cupro is a regenerated cellulose fabric made from cotton waste. It is made using the teeny tiny silky cotton fibres, known as linter, that stick out of the cottonseed and are too small to spin. The linter is dissolved into a cuprammonium solution, which is a mixture of copper and ammonium, dropped into caustic soda, then spun into fibre. Much like Tencel and Modal, cupro is a plant-based material that is chemically processed to produce the resulting fabric.


Where it grows / Where it is made

Mostly China.



Fine garments, shawls, eveningwear, lingerie, blouses, summer dresses, other light and form-fitting clothing.


Impact on the environment

Despite being recycled, cuprammonium rayon has a decidedly negative impact on the environment. Rather than seeking solutions to environmental crises, manufacturers of cupro and similar fabrics are simply trying to figure out how to make money with waste products.


More sustainable alternatives

Lyocell, silk.


End of life possibilities

Can be disposed of using all end of life opportunities. Cupro is 100% cellulose and as such it is biodegradable. The fibre has also the potential for re-use and remanufacture. Where used as 100% cupro there is the possibility of using the fabrics as a raw material for regenerated cellulose fibre production. When present in blends, the end of life options are reduced. The re-use of the non-woven cupro fabrics will depend on the way they have been manufactured.


Our opinion

We would not recommend cupro as a fabric, process to make it is really harmful to the environment.
