Invista, owner of the Lycra brand, has purchased the dual core patent portfolio by Cone Denim and its parent company International Textile Group (ITG). The patent estate covers a variety of dual core yarns, fabrics, and garments made from those fabrics, which are sold in the U.S., China, and most recently, Europe.
“Given the growth of dual core technology in recent years, we are excited to add this technology to the Invista patent estate,” said Jean Hegedus, director of Invista’s denim business, and continues: “Both Invista and Cone Denim invented different technologies in the area of dual core fabrics and yarns. Invista already had several patents related to dual core yarns when the Cone patent was granted. Invista’s patents are focused on dual core yarns and fabrics made with two elastic fibers, for example the Lycra DualFX concept, employing Lycra and Lycra T400 in a single fiber, covered by cotton or another fiber. Cone’s patents focus on yarns and fabrics with a core of one elastic fiber and one inelastic fiber which are then covered with cotton. So the technologies are different but complimentary.”
Invista was a pioneer in the development of dual core technology as their first patents in dual core were started in 2000 and commercially introduced as the Lycra DualFX fabric concept in 2010. Cone Denim, instead, launched its dual core technology only in 2007.
“This year marks the 10th anniversary of Cone Denim’s development of its dual core patented innovation, trademarked as Sgene technology,” says Steve Maggard, Cone Denim’s senior vice president of operations. “Cone is pleased to collaborate with Invista to provide a global platform to take this technology to the next level and will continue to produce yarns and fabrics made with the Sgene technology under a license from Invista.”
In April 2017 Cone Denim’s dual core patent was granted in Europe and is now part of the Invista patent estate. “The granting of the EU patent marks another milestone in dual core technology and should provide new opportunities for Invista’s customers,” Hegedus said. Over the next several months, Invista will be meeting its customers and other fabric producers to discuss its expanded dual core patent estate and license requirements.
