One of the world’s largest integrated producers of polymers and fibers, Invistawill launch two new Thermolite® brand technologies at the upcoming Kingpins denim show in New York City. Both innovations offer a high level of performance that may change the way we think about what jeans to wear in colder conditions.

Thermolite® Infrared technology and patented Thermolite® Dual Layer technology are the first offerings under a new brand category called Thermolite® Pro. At Kingpins, Invista will demonstrate how these technologies provide a higher level of warmth and insulation than traditional denim fabrics.

According to Jean Hegedus, global segment director for denim at Invista, the THERMOLITE® PRO innovations were driven by consumer research* that showed that more than 70 per cent of respondents were interested in the concept of a winter jean.

Denim fabrics made with Thermolite® Infrared technology increase their temperature when exposed to solar or artificial light. Special ceramic pigments are added to the fiber that transfer the energy of infrared rays into heat the body can feel. For example, after three minutes under infrared light, surface temperatures of fabrics with infrared yarns increased two to four degrees Celsius, depending on the content of the infrared yarn in the fabric.
