Teijin to Mass Produce Nanofiber Filament
Made from Recycled Polyester
Tokyo, Japan, April 12, 2021 --- Teijin Frontier Co., Ltd., the Teijin Group fibers andproducts converting company, announced today that it has developed technology tomass produce a new version of its Nanofront® ultra-fine polyester, which the company
believes is the world’s first nanofiber to be made from recycled polyester raw materials.
Moreover, the new technology will enable Teijin Frontier to produce all of its polyester
fiber products with recycled raw materials.

Teijin Frontier expects filament and textiles made with this new version of Nanofront®
made from recycled polyester materials to replace conventional Nanofront® made frompetroleum-derived raw materials in a wide range of fields, including sportswear,
functional clothing, industrial uniforms and more. The company is forecasting sales ofrecycled-polyester Nanofront® to reach JPY 300 million in fiscal 2021 and JPY 800
million in fiscal 2025.

In recent years, the demand for Nanofront® has expanded in a wide range of fields due
to growing needs for materials offering high functionality, such as absorbency and grip,
and excellent comfort including soft texture and low skin irritation. Meanwhile, thedemand for recycling raw materials is rapidly increasing, but it has been difficult to mass
produce ultra-fine fibers made from recycled polyester due to needs for high-level
polymer control and spinning. Teijin Frontier has now developed new polymer-control
and spinning techniques for Nanofront® made from recycled polyester materials. The
key was the company’s proprietary “sea-island” composite-fiber processing technology,
which distributes two types of polymers into the fiber’s "sea" and "island" parts, thendissolves and removes the "sea" part using an alkaline, etc. treatment, and finally
extracts only the "island" part as raw yarn.
