A Proud History and a Bright Future

In 2004, subsidiaries of Koch Industries acquired INVISTA from E. I. du Pont de Nemours and Company. INVISTA, formerly DuPont Textiles and Interiors, was combined with KoSa, a producer of commodity and specialty polyester fibres, polymers and intermediates. KoSa had been a Koch affiliate since 1998. In 2021, INVISTA Performance Technologies was renamed Koch Technology Solutions (KTS) and became a part of Koch Engineered Solutions.

KTS’ heritage stretches back to the beginning of the polyester industry via our predecessor companies, ICI and DuPont, and continues to this day.
