Why Copper?

Copper has been used for thousands of years as a biocidal agent to destroy microorganisms. During this time NO microorganisms have developed a resistance to copper! Copper ions, either alone or in copper complexes, have been used for centuries to disinfect liquids, solids and human tissue. Today copper is used as a water purifier, algaecide, fungicide, nematocide, molluscicide, and as an anti-bacterial and anti-fouling agent. Copper also displays potent anti-viral activity.

Cupron is the name of the company that infuses copper into the fabric, they call it Cupron Fabric.  Cupron’s manufacturing technology permanently binds its proprietary copper compound to textile fibers, non-woven fabrics, paper, latex and other polymeric products. Highly sophisticated, implementation of this technology does not involve complicated or hazardous manufacturing methods. And best of all, the protection offered by Cupron-based products will last as long as the products themselves, regardless of the multiple hot water washings, abrasion or bleach.

How Copper Socks Work

Cupron Fabric works by releasing copper ions. These copper ions damage the cell wall of the bacteria, damage bacteria DNA, and damage the bacterial proteins.
