NEFFUL & Teiken: Innovators in Negative Ion Fabric Technology

NEFFUL and Teiken Ltd. have combined their advanced textile expertise to develop the innovative NEORON® Fabric Fibre, seamlessly integrated into clothing and bedding merchandise that promote a healthy lifestyle. This pioneering manufacturing technique has created a premium fabric that generates negative ions upon skin contact. Engineered for daily wear, the NEORON® fabric fibers naturally release negative ions through gentle friction and body movement, allowing these ions to be safely absorbed through your skin—the largest organ in your body.

Teiken Ltd. exclusively develops award-winning NEORON® fibre for NEFFUL International, integrating premium fabric material blends to create superior healthy living garments, luxury blankets, and bedsheets. These products build upon the historic success of their original Teviron fibre brand, offering enhanced well-being benefits, excellent product durability, and continuous physical comfort.

The History Behind NEFFUL’s Journey

The journey began in 1957, when Nefful started researching advanced textile technology in Shizuoka, Japan. In 1973, founder Hisami Kamijo introduced Teviron fibre, a pioneering fabric developed to support daily well-being, better sleep, and ultimate physical comfort. Nefful expanded its premium product range in 1979 by launching the Teviron series, which successfully ushered in a global philosophy centered around a healthy lifestyle and passive wellness.

Building on decades of award-winning innovation, Teiken Ltd. launched the next-generation NEORON® fabric in 2014. This advanced material represents a major evolution in negative ion technology, generating ions naturally through everyday friction and skin contact. Engineered for versatility, NEORON® fabric offers exceptional thermal insulation, superior moisture permeability to keep skin dry, and certified flame resistance. These premium material qualities ensure that our high-quality clothing is thoughtfully crafted to provide the highest support from adults to children.
