Cupro has been in continuous development for 20 years
Cupro, a regenerated cellulosic fibre, by Asahi Kasei is the material of choice for a number of premium brands. Nakajima Yasuyoshi, the president of Asahi Kasei Fibers Italy, in conversation with Fibre2Fashion, talks in detail about the fibre and its USP.

How is the Cupro material better than cotton?

It is very difficult to compare these fibres, even if they are linked from a 'sourcing' point of view. Cupro has been one of the first to practice circular economy sourcing its key raw material from another industry, one of the cotton seed linters that is a sort of 'bio-utility' waste very valuable for Cupro. Cupro is known for its silk-like precious touch and feel, thanks to its key characteristics.

How is Cupro manufactured?

Cupro is a regenerated cellulosic fibre. The making of Cupro is a process of continuous development, one that has been highly refined over the last 20 years. Beginning with its natural derived and abundant bio-utility source of cotton seed linters, it is then converted through a proprietary closed loop transformation process.

What are some of the unique features of the material? What makes it different than the other materials of its ilk?

Cupro has advanced smart features due to its structure. Cupro's specialised engineered structure creates dynamic and beneficial physical relationships with everyone who wears it, thanks to the highly refined and researched yarn and fibre formats designed by Asahi Kasei.
  • Cupro comes in either high shine or matt filament yarns
  • Cupro also comes in soft spun formats
  • Cupro's amorphous structure absorbs moisture better than other fibres
Cupro means excellent comfort. Temperature regulation and control is a key element in contemporary fashion. Cupro defines and proves modern comfort with measured metrics.
  • Cupro gives you year round comfort, both cool and warm, summer and winter;
  • Cupro is temperature regulating
  • Cupro is antistatic
Cupro has a near-perfect circular cross-section that creates a smooth and precious pearly lustre. This is also the reason behind its unique touch and delicate skin anti-resist feel and neutral skin response. Cupro is cool and sensual with a beautiful, supple drape. Its soft versatility makes it perfect for the modern wardrobe fashions, athleisure and everyday casualwear.
  • Cupro is soft and smooth and sleek
  • Cupro is perfectly gentle on the skin

Cupro is quite a sustainable material. From the seed to the final fabric-what steps are taken so that it is eco-friendly all through?

Our process starts and is based on the circular economy approach as its 100 per cent raw material-cotton linters-is a bio-utility waste, meaning a by-product removed to increase yield when producing cotton addition. Cupro production has improved energy and water use, recovering almost all materials used in the process with a good waste management system, and now Cupro can also claim biodegradable disposal, as verified through the Innovhub third party test. In addition, Asahi Kasei has just finalised an LCA study, signed by ICEA. This important step builds and confirms a new quality profile and standards for this one-of-a-kind material, helping to define and secure Cupro's more responsible and unique position today, while facilitating and measuring continued smart improvements in the future.
