The far infrared ray is a kind of invisible rays, also belong to electromagnetic wave. It is easy to be absorbed and turned into the internal energy of object, because of it has stronger penetrating power, temperature-controlled and resonance effect. So the far infrared ray is used in the physical treatment of medical science of recovery therapy extensively, its principle is that far infrared ray is absorbed by human being, can make internal water molecule produce resonance, transmit far infrared heat energy to human cover deeper layer organization , make some parts temperature rise, send out from inside to outwards, because of this, the capillary is expanded, promote blood circulation and metabolism, thus strengthen the organic regeneration ability.
   In our company, the granularity of the far infrared powder of nanometer is 0.2 microns , the wavelength of normal temperature is 2-- 18μm, far infrared emissivity is 91%, possessing with the function of resist ultraviolet ray , sterilize , dispel peculiar smell , preventing and curing diseases etc.. And it is also the best raw materials of new products such as the health care, fabrics ,etc., can improve human body circulation , impel normal circulation blood flow increase by 2-3 times effectively, advance organize for supporting oxygen , improve metabolism , strengthen immunity. This powder as additive makes into far infrared fiber with the function of fine health care physiotherapy, thermal effect.
   Generally some health care enterprises such as in Japan, Taiwan ,etc., a plenty of scientific experiments show, the effect of far infrared is more outstanding when the proportion added in fabrics is moderate, generally the ways of using in the two major classifications, pastern and Muli in textile.

   Before using, we must make the powder or grains for 1 micron and even below. At present, there are two technological craft routes. Firstly, making the pharmaceutical use the far infrared powder, adhesives and activator in the certain proportion among process, and then go on coat and soak for textile, put the pharmaceutical smear equably on fiber, it makes to be far infrared powder adhere to between the yarn of the fabric and the fiber of the yarn through dryness, heat treatment; Second adopt and mix spinning together, put the nanometer powder evenly append to original fluid of filature, then spin out the high polymer fiber with the far infrared..
