Lycra brand owner Invista said it bought the dual core patent portfolio of Cone Denim and International Textile Group (ITG).
“The patent estate covers a broad variety of dual core yarns, fabrics, and garments made from those fabrics, which are sold in the US, China, and most recently, Europe,” said Invista.
Jean Hegedus, director of Invista’s denim business, said: “Given the growth of dual core technology in recent years, we are excited to add this technology to the Invista patent estate.
“We look forward to working with our customers and licensees to expand the Lycra dualFX fabric business.”
Steve Maggard, Cone Denim’s senior vice president of operations, said: “This year marks the tenth anniversary of Cone Denim’s development of its dual core patented innovation, trademarked as Sgene technology.
“Cone’s Sgene technology integrates a stretch fiber, such as Lycra fiber, with an inelastic control filament.
“Cone is pleased to collaborate with Ivista 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.”
