More and more textiles for neurodermatitis, sports textiles, etc. contain nanosilver. Due to their size, these tiny silver nano particles can penetrate through the skin into each cell. The Federal Environment Agency warns about major knowledge gaps.
Thick layers of “metallic silver“ on the other hand is safe for the environment and human health. All our silver coated yarns and silver fiber/plated textiles are coated with mini. 99% “metallic silver“. Even if particles should come off one day due to heavy use (e.g. clothing, bedding) they are far too big to penetrate through the skin!
