What is Cupro?

Cupro (Cuprammonium Rayon) is a "regenerated cellulose" fiber. It sits between natural and synthetic. It is not grown like a plant, but it is not a plastic like polyester. It is made from Cotton Linter, the fuzzy, ultra fine fibers that stick to the cotton seed after the main cotton is ginned.

1. How It Is Made

Cupro is produced by dissolving the cotton linter in a solution and spinning it into fiber.

  • The Solution: The linter is dissolved in a solution of copper and ammonia, which gives cupro its name.
  • The Spinning: The dissolved cellulose is spun into fine, smooth filaments.

2. The Feel

Cupro is often compared to silk for its hand feel. We call it cupro, because it is a regenerated cellulose fibre and not a protein fibre.

  • Smoothness: The fibers are perfectly round and smooth (unlike cotton, which is twisted). This gives it a slippery, cool-to-the-touch texture that glides over the skin.
  • Drape: It has a fluid, heavy drape similar to sandwashed silk, making it ideal for dresses and lining.

3. Moisture Control

Cupro is highly breathable and moisture-wicking. It releases moisture into the air rapidly, reducing the "stickiness" often felt with synthetic linings. It is also anti-static, meaning it won't cling to your legs in winter.

4. Where Ours Is Made

Our cupro pyjamas are cut and sewn near Ferrara, Italy, by a family owned atelier.

Conclusion

Cupro shows what careful technology can do with a humble raw material: it turns cotton linter into a fluid, breathable fabric with a drape that is often compared to silk.
