A look through an electron microscope shows the silver and copper embedded throughout purthread fibers
Silver spoons, silver chalices, silver coins in water pots. There's a reason this precious metal has been used for millennia to keep our water pure, to feed our infants, dress our wounds, and treat our eye conditions. Though we've only recently begun to understand how silver kills microbes, we've long recognized its natural antimicrobial properties and relied on it to keep us safe.
This powerful combination is practically unstoppable. PurThread uses its trade secrets and patented technology to embed these silver and copper salts into our fibers during the molten stage of production, making PurThread's antimicrobial protection intrinsic to every thread. For the life of the product. Unlike antimicrobial dips and coatings, PurThread's protection is consistent throughout the fabric and has been proven never to weaken, wear off, or wash away. Even through 100 industrial launderings.

How Silver and Copper Kill Microbes
Individually, silver and copper kill microbes through multiple pathways - and together, they show synergies across a wide spectrum of microbes. A key killing mechanism is through interruption of the cell's ability to form the chemical bonds necessary for survival. These bonds produce the cell's physical structure - think cell walls, so when bacteria come in contact with the silver and copper embedded in PurThread, they literally fall apart and die.
