Teijin Frontier Co., Ltd. has developed Solotex Thermo, a polytrimethylene terephthalate (PTT) fiber offering excellent thermal retention and insulation. Teijin Frontier envisions a wide range of promising applications for its new fabric, including jeans, pants and other bottoms, as well as for more than just outer materials.
Solotex Thermo offers high comfortability thanks to its softness, form-suitability and stretchability. It absorbs near-infrared sunlight, and converts it into heat efficiently due to carbon-based inorganic particles mixed into the fiber’s monocular structure. Compared to a conventional polyester fiber, it raises the wearer’s wind-chill factor by 5°C, as demonstrated in a sunlight heat-storage test conducted by the Boken Quality Evaluation Institute.
Teijin Frontier is exploring marketing opportunities for Solotex Thermo mainly for outerwear. Annual sales are expected to reach 500 tons by the fiscal year ending in March 2021.
