Takisada-Nagoya has developed high-performance thread NIROL™ that utilizes inorganic rare metals (CWO™).

Takisada-Nagoya proposes NIROL™, a near-infrared ray-absorbing fiber originally developed in cooperation with Sumitomo Metal Mining Co.Ltd., for apparel, sports, miscellaneous goods, and other fields.We will deliver sustainable functional fibers that anyone can experience.

Features of NIROL™

Coloring possible

Coloring is possible. NIROL™ is suitable for coloring not only black and gray products that use black absorbents, such as conventional heat-storing/heat-retaining materials, but also highly bright products including white ones, enabling development of highly fashionable clothing products.

Long-lasting physical properties/effects

Since a special inorganic material is kneaded in the fiber, WarmdArt® has long-lasting effects. With only a small amount of material added, the fiber has the same properties as those of existing polyester fiber.


Using recycled polyester, NIROL™ provides a sustainable material that is environmentally friendly from various points of view.

Quick drying/prevention of chilling from sweat

Under the sunlight, due to its high heat-storing function, dries in about half the time compared to ordinary polyester materials.
