Invista announced Friday the purchase of International Textile Group’s (ITG) subsidiary, Cone Denim’s, dual core patent portfolio.

The portfolio covers a number of dual core yarns, fabrics and garments made from those fabrics sold in the U.S., China and 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. “We look forward to working with our customers and licensees to expand the Lycra dualFx fabric business.”

Hegedus said the move is a logical expansion of its dual core portfolio. Over the next several months, Invista plans to meet with customers and fabric producers to further discuss the dual core patent license requirements and estate.

Cone Denim celebrates more than 125 years of heritage and innovation, with this year marking the 10th anniversary of the company’s creation of its dual core patented innovation, trademarked as Sgene technology—another innovation notch Invista can add to its belt.

“Cone’s Sgene technology integrates a stretch fiber, such as Lycra fiber, with an inelastic control filament,” said Steve Maggard, Cone Denim 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.”
