The superior antibiosis, nano silver yarn, has been certificated and issued by medical FDA organization in health and disease except passing numerous experiments.
Silver in the yarn is highly germicidal, quite harmless to humans and absolutely non-toxic. Rather than in a chemical compound, all virus, fungus, bacterium, streptococcus, staphylococcus, and other pathogenic organisms are killed in three or four minutes upon contact. There are no side affects whatsoever from the melting concentrations...

Nano silver has came through by melting concentrations into yarn not only treat the surface with silver. Its antibacterial function is permanency and has done the testing by 300 times of washing whose skill has not reduced a tiny bit.

Silver has the ability with electric conductivity which only needs few percent of silver in garments can eliminate static and turn static into magnetic field rapidly; besides, the magnetic field strengthen the blood circulation.
