Far-infrared fiber is made by adding powder with far-infrared function (some metal or non-metallic oxide with function and crushing to nanometer or micro-nano-sized powder) in spinning process. The far infrared function achieved by this method is strong and will not disappear with water washing.

In recent years, far-infrared fiber has been widely concerned and has been put into production. Most of the far-infrared fiber is made by adding far-infrared absorbent (ceramic powder) in the process of processing. It is a kind of high-efficient thermal insulation material.

In the mid-1980s, Japan first developed and introduced far-infrared fabrics to the market. At present, the combination of far infrared fiber and magnetic therapy is promoting the birth of composite health fabric.

Far infrared fiber can be made such as down pedal, socks, knitted underwear and other household goods. These products not only satisfy the basic application, but also have a certain health care function.

There are generally two views on the health-care principles of far-infrared fibers. It is believed that 99% of the energy absorbed by far infrared fibers is in the wavelength range of 0.2 ~ 3 μ m, in which the infrared part (> 0.761 μ m) accounts for 48.3%. Ceramic particles in far-infrared fiber can fully absorb short-wave energy (far-infrared part energy) from solar light and release it in the form of potential (far-infrared form) so as to achieve the function of keeping warm and healthy. The other is that the far infrared fiber can store the heat emitted by the human body and then take the form of far red as a result of the extremely low conductivity of ceramics and the high emissivity, then let out the fabric to increase the warmth of the fabric.
