Silver has been used for centuries to prevent and treat a variety of diseases, especially the infective types. It is well documented as silver coins were used in ancient Greece and at Roman times to disinfect stored water and many other liquids. Even today, NASA uses silver to preserve the purity of the Space Shuttle.
Because silver can eliminate a broad-spectrum of microbes. It works on microorganism cell walls. Thanks to this property, copper helps to reduce bad odor caused by some microbes.
Moreover this type of yarn has a Reflecting poweR. The reflectance of infrared (IR) in silver is greater than 95%. This value is higher than any other element, and it means that 95% of the radiant energy which comes into contact with silver is reflected back to its source. Consequently Resistex® Silver reduces to a minimum the dispersion of heat, reflecting on the skin its own energy. For this reason, clothing made with winter Resistex® Silver are much warmer than regular ones.
