Dr. David's men's underwear is mainly made of soybean protein fiber. Soybean protein fiber won the World Invention Patent Gold Award and China Invention Patent Gold Award. After ten years of hard exploration and 800 times of unremitting research, Mr. Li extracted soybean protein fiber from soybean meal, which was not developed at a cost of hundreds of millions of dollars in Japan and the United States. This technology is the pride of China people.
Adopt the only plant protein fiber in the world, 100% green and healthy, soft as cashmere, skin-friendly, breathable, warm and antibacterial. The difference between soybean protein fiber fabric and ordinary fabric lies in its strong ability to absorb sweat and expel moisture. Metaphor: a pair of pure cotton underwear may take 12 hours to dry thoroughly, while soybean protein fiber only takes 4 hours.
Soybean protein fiber also has the functions of sterilization, bacteriostasis, releasing negative oxygen ions, releasing far infrared rays, and resisting ultraviolet rays. The principle that other products in the ladies' model release far infrared rays is to crush tourmaline, medical stone, muyu stone and other stones that release far infrared light waves to nanometer level, and then soak the cloth in them.
Or by high-pressure spraying on the goods sold, although this technology has been advanced for a while, it will slowly fall off with the wearing and washing of the human body, which means that it may have a good effect at first, but it will have no effect after a long time.
On the other hand, Dr. David implanted far-infrared light waves into every fiber of underwear. This technology is a secret technology of the military and will not be weakened by washing or long-term wear. Even if you burn your underwear to ashes, there is energy in it. Every set of our products has the test report of the national far infrared department.
