Far Infrared fiber refers to fiber that 'emits' far infrared rays. Our Far Infrared (FIR) Fiber is made from 95% polypropylene and 5% special lead-free ceramics utilizing our patented technologies. The ceramic is the key for 'emitting' the far infrared rays.

The ceramic that 'emits' FIR is commonly called bio-ceramic. Bio-Ceramic is made from many different kind of ceramics mixed with mineral oxides, likes Silica Oxide (SiO2), etc. The mixture is heated together at 1600 degrees centigrade to form the FIR emitting ceramic. After cooling down, it becomes the lead free, bio-ceramic with FIR emitting properties.

The bio-ceramic is then ground into micro particles in nano scale and inseminated into polypropylene during the polypropylene fiber forming process. The fiber is then stretched, twisted and made into various forms for various needs. Unlike soaking or coating process, with the insemination process, the bio-ceramic particles stay inside of the fiber and they cannot be dropped from washing. Because the bio-ceramic particles are in nano scale; they are so small and can stay inside the fiber no matter how thin it is.

Once the FIR fiber is manufactured, it could be made into waist wraps, knee bands, shirts, underwear, pillows, sheets, etc. anything people like. FIR wear could be comfortably worn indistinguishably from normal clothes.

How can the bio-ceramic emit far infrared? Will there be any side effects? While, the principle is very simple. It is a well-known fact that human body constantly emits thermo energy. When the bio-ceramic is stimulated by the thermo energy of human body, it converts it into the far infrared rays and reflects it back into the human body. So the far infrared ray emitted by the far infrared fiber is really powered by our own body and there are no known side effects.
