The origin and characteristics of tourmaline long before the development of modern mineralogy, people used to name gems according to their colors. /kloc-in the middle of 0/500, a Portuguese expedition first discovered a kind of colored gems in Brazil, named tourmaline, which means "colored gems". Since then, tourmaline, as a precious ornament, has been deeply loved by European nobles and ranked among the world's 12 gems. 1703, the Dutch discovered that this gem has the ability to absorb ash, so it was named "ash-absorbing stone". 1880, the Curie family revealed the secret of this gem, that is, tourmaline crystal has permanent self-generating property, and a micro current of 0.06mA flows on its surface, so it was named "tourmaline". Research shows that tourmaline is the only mineral with permanent electrodes on the earth. 1986 Japanese researchers confirmed that when tourmaline is crushed, with the increase of surface area, the energy increases year-on-year, that is, the finer the crushing, the greater the energy. This discovery accelerated the development and utilization of tourmaline.

Liquid tourmaline technology The processing technology of liquid tourmaline originated from South Korea, that is, the high-tech technology of 2 1 century is used to crush tourmaline crystals into ultrafine liquid, and the post-bonding technology is used to closely combine with the hydroxyl groups of fabric fibers to form stable tourmaline fibers. This combination makes good use of the fiber structure and physical and chemical properties of tourmaline, and has the characteristics of good stability, never falling off, wear resistance and washing resistance. According to the detection of relevant departments, tourmaline fiber and tourmaline crystal have the same life energy. Therefore, the series of health care products made of this fiber are in the leading position in the world, both in terms of scientific and technological content and health care efficacy.
