SILVADUR™ antimicrobial technology inhibits bacteria growth and buildup of microbes on fabric surfaces. These microbes often destroy fabric integrity, shorten its useful life, and can cause discoloration, spoiling and staining. SILVADUR™ polymer-containing silver technology releases silver ions to neutralize odor-causing bacteria upon contact with your clothing. SILVADUR™ ensures fabrics stay fresh without affecting the fit, feel, or finish of the treated garment. HOW IT WORKS - Silver contains inherent antimicrobial properties. It has been a time-tested antimicrobial used since ancient times in healthcare, food preservation, and water treatment as well as other applications where effective, long-term bacterial protection is required. Silver is a leading antimicrobial due to its safety for human contact, long term efficacy and prevention of growth for a broad range of microorganisms. HOMOGENEOUS FINISH - SILVADUR™ antimicrobial technology provides uniform distribution of silver ions throughout the fabric– ensuring comprehensive protection and long-lasting freshness. RESISTS YELLOWING - Fabrics treated with SILVADUR™ antimicrobial technology will not fade or yellow over time. NO LEACHING - SILVADUR™ long lasting antimicrobial won’t ever cross the skin barrier or migrate from the fabric. This means that SILVADUR™ antimicrobial won’t impact the micro-flora, or good bacteria, when in contact with skin.
