Tokyo, June , 2026 --- Teijin Frontier Co., Ltd., a Teijin Group company, today announced the development of a polyester fiber-based textile that uniquely performs two functions, which are difficult to achieve simultaneously.

The new textile provides both excellent heat retention, delivered by its structure, and stuffiness suppression, provided through its high breathability.
