Tokyo-based Teijin Frontier Co. Ltd. announced it has developed a stretch polyester yarn offering compatibility with high-performance polyester materials for sports and outdoor wear.
According to the company, its proprietary polymer design and spinning technology impart elasticity to the yarn, adding stretchability and recovery to high-performance polyester materials. The yarn’s elasticity derives from polymer design and spinning control technology rather than yarn structure, providing soft stretchability and shape stability with recovery comparable to polyurethane-based elastic fibers.
The yarn enables development of 100% polyester textiles that maintain advanced functions including moisture absorption, quick drying and durable water repellency. The all-polyester composition also simplifies recycling.
Teijin Frontier plans to combine the yarn with high-performance polyester materials in textiles for sportswear, casual wear and innerwear. The company will begin selling to domestic and overseas markets in 2027, targeting annual sales of 100,000 meters in fiscal 2027 and 500,000 meters in fiscal 2029.
