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