Manufactured by a World’s Most Ethical Company®, as awarded by Ethisphere Institute, Eastman cellulosic yarn has received certification by the U.S. Department of Agriculture’s BioPreferred program. Eastman cellulosic yarn meets human-ecological standards with direct contact to skin demonstrated by its Product Class II certification with the Oeko-Tex label. Eastman is also a proud member of the global Sustainable Brands organization.


Eastman Naia cellulosic yarn is derived from renewable wood pulp, sourced exclusively from sustainably managed forests—never from endangered or old growth forests. It is produced in a near-closed-loop process located in the United States where all waste is either recycled, reused, or offered for resale. Naia is manufactured without chemicals listed on the ZDHC MRSL and does not require any substances that would require warnings as per California's Prop 65.

Naia Ease of Care


During the production of Eastman cellulosic yarn, production solvents and material waste are recycled back into the system for reuse. Water returned to source streams is processed in our state-of-the-art, bioactive waste water processing facility and is routinely tested to ensure that the biodiversity of our local river is receiving clean and safe water. Naia is certified biobased under the USDA BioPreferred program, unlike generic viscose, polyester, and nylon.


We care about the safety and well-being of our employees, the environment, and our communities around the globe.
