It is made by specially-processed nanotechnology with certain percentage of Nano far infrared powder dispersing into melt PET in the spinning process.

1.Far infrared fiber can launch wavelength 4-14um far infrared ray, postbox emissivity ≥ 92%;2. Soft feel, hollowness degree≥ 20%

The fiber inside contain large amount of air being held up to keep warm. Its fabric can absorb heat from human body and external world, then launch 4-14um far infrared ray to human body, which have functions of “radiation” “penetration” and “resonance”.
