WILMINGTON, Del. — Aug. 29, 2011 — DuPont Industrial Biosciences, today announced that DuPont™
Sorona® has received Oeko-Tex® Standard 100 Class 1 Certification from Oeko-Tex® and the Hohenstein
Textile Testing Institute. Sorona® renewably sourced polymer is certified for use in fiber
applications for textiles (apparel, home, office, and automotive interiors) and for carpet
(residential, commercial and automotive including mats). Oeko-Tex® Class 1 certification is the
most stringent test and includes textiles and carpets intended for use by infants and toddlers.
“Receiving Oeko-Tex® Standard 100 Class 1 certification for Sorona® provides third party
validation of the safety of Sorona® for use in all fiber applications,” said Walter L. Fields, III,
global business director. “This will benefit our downstream customers, and we will work with them
to get further Oeko-Tex® certification throughout the supply chain. For carpet mills, apparel
brands, and consumers, this certification provides the confidence they need to select high quality
textiles and carpets.”
DuPont™ Sorona® is made, in part, with annually renewable plant-based resources. By
replacing traditional petrochemical ingredients with those made from renewable resources, Sorona®
helps reduce dependency on oil and petrochemicals. Additionally, the production of Sorona® offers
significant energy savings and reduced CO2 emissions when compared to the production of an equal
amount of nylon. Sorona® is also free from heavy metals.
“We are very pleased that DuPont chose Oeko-Tex® Standard 100 certification for Sorona®.
Sorona® is one of the first bio-based textile polymers to demonstrate highly desirable technical
and life cycle advantages for a wide range of products from apparel to carpets. Oeko-Tex®
certification verifies Sorona® is free from dangerous levels of harmful substances and meets REACH
and CPSIA requirements in the EU and USA. This certification is further assurance of the
desirability of this fiber for many textile designers concerned about long term sustainability and
technical superiority,” said Sam Moore Ph.D, who represents Oeko-Tex® in North America.
DuPont works with a global network of licensed fiber producers and mills – both fabric and
carpet – to bring a wide variety of Sorona® textile and carpet products to market. In apparel
segments, Sorona® can be easily blended with a broad range of other natural and synthetic fibers to
provide exceptional softness, comfort stretch, durability and easy care to a wide variety of
garments including swimwear, intimate apparel, denim and ready-to wear.
Carpet applications showcase the performance attributes that Sorona® adds including
durability and crush resistance as well as permanent, natural stain and bleach resistance that
won’t wash or wear off.
The unique combination of attributes and benefits of DuPont™ Sorona® earned it a new
sub-generic fiber classification from the U.S. Federal Trade Commission in March 2009. In the
United States, the new generic for Sorona® is triexta. In 2011, Sorona® became one of the first
products certified by the USDA Biopreferred labeling program.
