Biochar, tourmaline, volcanic rock and other materials are made into nanoparticles, which are added to textile materials to make far-infrared health care fabrics. Due to the cost problem, the far-infrared materials in the health care fabrics on the market are mostly quasi-nanoparticles, which have the function of reflecting the heat emitted by the heating body back and promoting and improving blood circulation. As for the effect of eliminating pain and inflammation, there is in theory, but the effect is minimal.
The' Selam' material on the market is actually far-infrared acrylic fiber. It is made by adding nano or quasi-nano particles with far infrared function into acrylic fiber spinning dope. The far infrared ray is used to store the heat energy of the human body and then return it to the human body. Better warmth retention, but not too much. Raising the temperature by 7℃ to 8℃ is even more exaggerated.
Extended data
A pair of warm pants is made of multi-layer warm-keeping materials, and is characterized in that the warm pants are woven by pure cotton yarn combed inside and outside and interlayer warm-keeping cotton, and the abdomen, back waist and knees of the warm pants are respectively provided with thickened layers, which are composed of three layers of metal film warm-keeping cotton and far-infrared filaments (close to the body) from inside to outside.
Warm pants adopt new technology and add special materials to fibers. When spinning, zinc oxide or zirconia and other ceramic materials close to nanometer level are added to the fiber. Because these ceramic materials can stimulate the microcirculation of human blood, they can play a certain role in warming up.
