DuPont has announced the 20th anniversary of its first commercial run for the 3G2 production line at the Kinston, North Carolina plant site, signifying the launch of the world’s first 3GT polymer, known by its trademark Sorona. To mark this milestone, celebratory events will be held to pay honor to the history of Sorona, and to focus on its future.
“We’re proud of the role Sorona has played over the past 20 years in making the textile industry a more sustainable place,” said Mike Saltzberg, DuPont Biomaterials global business director. “It’s exciting to be part of an industry that puts performance and sustainability at the forefront of everything they do.”
DuPont developed Sorona in the late 1990’s by leveraging the innovative bio-based monomer Bio-PDO as the basis for the polymer. The development process for DuPont Sorona begins by harvesting feedstock and extracting glucose from the crops. Next, proprietary microorganisms are added to ferment the sugar to create Bio-PDO. TPA (terephthalic acid) is added to the monomer to create Sorona polymer, offering spinners, mills, retailers and consumers a high-quality, eco-efficient product that doesn’t sacrifice performance.
