What is cupro?
Cupro is what is called an artificial textile fibre. A chemical process is needed to transform cellulose, the main component of various plants (such as wood, cotton, bamboo, etc.) into reconstituted fibres. Take, for example, the linter of cotton, which is the fluffy fibre that envelops the seeds of a cotton plant. This fibre is dipped and dissolved in an ammoniacal solution of copper oxide called cuprammonium (Does this also remind you your chemistry classes in high school? ;) ) You now understand the origin of the name 'Cupro'. The whole name of the fabric is Cuprammonium rayon.

The mixture is then immersed in moving hot water. This goes so fast that the cellulose splits into threads that will be assembled into yarns to give the finished fabric named Cupro!
But do not leave right away. This was only the (complicated) explanation of the manufacturing of Cupro.
Cupro, is it a sustainable fibre?
Cupro is made of natural materials but the fabrication process is chemical. Nevertheless the fabric itself once manufactured is completely biodegradable. And the waste produced during the process is almost 100% recycled. Its ecological footprint is, therefore, lower compared to other materials used so far in large quantities (viscose for example).
The advantages of Cupro
Cupro has a light shine like satin and feels very soft. It is a fabric that because of its great breathability, and its speed of absorption of moisture or air is an antiperspirant. It is also thermo-regulating and hypo-allergenic. In short, it dries quickly, breathes well and will keep you cool in summer and warm in winter. Doesn't that sound perfect?

Cupro by Asahi Kasei Corporation
The best known and largest producer of Cupro is Asahi Kasei Corporation, a Japanese company. Their Cupro is sold under the Bemberg ™ brand, it is certified LCA (Life Cycle Assessment), Biodegradable INNOVHUB-SSI, GRS (Global Recycled Standards), Eco Mark, OEKO Tex Standard 100 and ISO 14001. To learn more the explanations of the site of Asahi Kasei Corporation are very easy to understand.
How to wash clothes of Cupro?
Cupro can best be washed at 30 degrees Celcius. The fabric does not wrinkle much, but if you want to, you can iron or steam clothing from Cupro. Always read the washing instructions in the clothes itself to be sure of how you can best wash the piece of clothing. Washing at a low temperature is also good for the environment! :)
Cupro at MaeSue.com
At Mae Sue we have a few clothes made of Cupro at the moment, from the brand Näz. The fabric is a leftover fabric from another brand that has been left behind in a factory. Näz has used the deadstock fabric for beautiful tops and dresses. Leftover fabrics made of Cupro are, according to me, a sustainable option. As this fabric would have been unused otherwise.
