New York City - May 12, 2017

The LYCRA Company, owners of the LYCRA® brand, along with Cone Denim and its parent company, International Textile Group (ITG), announced today that The LYCRA Company has purchased Cone Denim’s and ITG’s dual core patent portfolio. The patent estate covers a broad variety of dual core yarns, fabrics, and garments made from those fabrics, which are sold in the U.S., China, and most recently, Europe. The purchase is effective immediately.


“Given the growth of dual core technology in recent years, we are excited to add this technology to The LYCRA Company patent estate,” said Jean Hegedus, director of The LYCRA Company’s denim business, who says that The LYCRA Company sees this move as a logical expansion of its dual core portfolio. “We look forward to working with our customers and licensees to expand the LYCRA® dualFX® fabric business.”

The LYCRA Company was a pioneer in the development of dual core technology with its LYCRA® dualFX® fabric concept, first introduced commercially in 2010. LYCRA® dualFX® technology encompasses stretch fabrics made with two stretch fibers – LYCRA® and LYCRA® T400® fibers – in a single yarn.

“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’s SGENE® technology integrates a stretch fiber, such as LYCRA® fiber, with an inelastic control filament. Cone is pleased to collaborate with The LYCRA Company 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 The LYCRA Company.”

Last month, Cone Denim’s dual core patent was granted in Europe and is now part of The LYCRA Company patent estate. “The granting of the EU patent marks another milestone in dual core technology and should provide new opportunities for The LYCRA Company’s customers,” Hegedus said. Over the next several months The LYCRA Company will be meeting with its customers and other fabric producers to discuss its expanded dual core patent estate and license requirements.
