Teijin Develops New Functional Polyester Fabric With Towel-Like Pile

Tokyo-based Teijin Frontier, the Teijin Group’s fiber products converting company, has developed what it calls a highly comfortable and functional polyester with the pile structure of toweling.

Made from 100 percent polyester, the new fabric absorbs water well, maintains a soft texture and has a “bulky-but-lightweight” feeling, according to the company.

Because of its structure, water diffusion in the novel poly is roughly five times faster than traditional fast-drying fabrics and heat insulation is three times greater than bulky fleece—heat is retained even when the material is wet.

Fleece has been widely used in outerwear and winter pajamas because its napping makes for ideal heat retention and warmth, but the drawbacks of the synthetic fiber fabric include deteriorating surface appearance and water absorption after ongoing washing and usage is really limited to fall and winter clothing.

So Teijin answered with a new false-twist yarn to provide the pile effect without the pitfalls. The company combined technologies from its Deltapeak material to create one fabric with the towel-like false-twist yarn, a warp-knitted multilayer structure and a specialized dyeing process for structural stabilization.

“Thanks to its pile structure without buffing, the new material’s surface appearance, functionality and comfort remain durable after repeated washing. In addition, the fabric structure is applicable for multi-seasonal products, not just fall and winter clothing,” the company noted in a statement.

Teijin is working on various applications of the new material for Fall/Winter 2016 sportswear and for functional clothing like underwear and uniforms, and also bedding and industrial materials. By 2019, the company hopes to reach sales of 500,000 meters (547,000 yards).
