The fabric of Dr. David's underwear is mainly soybean fiber, which is called "the eighth largest fiber in the world". Soybean protein fiber is a kind of regenerated plant protein fiber, which is made from squeezed soybean meal, extracted globulin from soybean meal by bioengineering technology, and changed the spatial structure of protein by wet spinning.
It has soft hand feeling like cashmere, silky soft luster, warmth retention of cotton and good skin friendliness, and has obvious antibacterial and bacteriostatic effects, releasing negative oxygen ions and far infrared rays.
In order to improve the health care effect of underwear on human body, the company uses the floodlight technology provided by the Institute of Energy Information to intercept the most beneficial 4- 14 micron band far infrared light wave from the sun, that is, the "life light wave" implanted in underwear products.
Advanced floodlighting technology can make the product contain 100% light wave energy, without changing the properties of the object itself, even if it is washed with water and machine for many times, it will not fail. Beyond the existing bioceramics, bamboo charcoal fiber, titanium germanium trace metal elements, tourmaline technology. No radiation, no electromagnetic wave, can act on human body safely, quickly and effectively.
