MILAN, Italy

Eastman is on a mission to make sustainable fashion more accessible through the availability of Naia™ Renew at scale, offering versatility for a broad range of fashion segments. Integrating Naia™ Renew into the denim segment brings Eastman one step closer to its mission of making sustainable style accessible to everyone.

The U.S.-based company is showcasing the potential of Naia™ Renew alongside several of its global brand partners, which are already using the innovative fibers in denim.

“The added value we provide brands is not only a fashionable but also a sustainable fiber,” said Carolina Sister Cohn, Eastman global marketing leader for textiles. “Naia™ has a strong and transparent sustainability story that brands can pass on to their customers and denim lovers all over the world, making them more aware of their choices. Third-party certifications play a key role in this scenario because what we promise is verified and proven.”

Denim Première Vision brings designers and manufacturers from around the world together every six months. Exhibitors like the Eastman Naia™ team share denim innovations and explore trends in the fashion segment to meet consumer needs.  

Naia™ Renew fiber blends well with natural fibers, other man-made cellulose fibers (MMCFs), synthetic fibers and multiple content yarns. This makes it the perfect ingredient for denim as it produces a sustainable and stylish fabric with an authentic look and feel that denim fans around the world will love.

Additionally, Naia™ Renew is hypoallergenic and skin friendly for denim that’s soft to the touch (before and after washing1), manages odor and moisture effectively2 and delivers better spreading speed. This makes denim blended with Naia™ Renew comfortable in any season.

Naia™ Renew is a cellulosic acetate fiber made from 60% sustainably sourced wood pulp and 40% certified recycled content.3  Certified recycled content in Naia™ Renew is diverted from landfills and broken down to its molecular building blocks via Eastman’s patented molecular recycling technology. The molecules are combined with sustainably sourced wood pulp to produce Naia™ Renew fibers for new textiles. This process produces a circular, fully traceable and biodegradable cellulosic fiber with a reduced carbon footprint. The process also reduces reliance on virgin material resources. 

Naia™ Renew has received multiple sustainability certifications, including Global Recycled Standard (GRS) and OEKO-TEX class 1. Eastman partners with companies like Patagonia and Debrand to recycle pre- and post-consumer waste for its molecular recycling technology to create Naia™ Renew fiber.

3Naia™ Renew recycled content is achieved by allocation of recycled waste material using a GRS-certified mass balance process.
