SILVADUR Antimicrobial Outperforms Alternative Treatment Systems

The unique technology system found in SILVADUR long lasting antimicrobial is the only credible and reliable alternative to the traditional – and, often costly and/or problematic - use of silver particle-based technologies.

The SILVADUR Advantage vs. NANO

A nano antimicrobial maintains and utilizes silver metals… or, you may think of it as the table salt not dissolving in water.

The SILVADUR Advantage vs. Silver Chlorides & Particle Based Delivery Systems

Traditional silver-based antimicrobial systems rely on the delivery and presence of silver particles on the fabric surface and depend on either silver leaching to control bacteria, or insoluble silver salts to release the silver. However, due to the particle size, many of these systems cause fabric discoloration and reduced antibacterial activity over time. In addition, the particulate nature of these products results in a non-uniform antimicrobial finish, meaning a higher effective cost-to-treat. All products that rely on this approach use solid materials, this often means limited applicability across the textile supply chain due to formulation difficulty.

The SILVADUR Advantage vs. Polymeric Quat Systems

You may also observe a SILVADUR antimicrobial advantage during the application process. Products treated with SILVADUR antimicrobial require less heat, less time, and no extra binders. Polymeric quat systems are difficult to control and require careful dilution, formulation and processing conditions. And, with the structure of the polymeric quat systems, fabrics become water repellent. This makes it difficult for manufacturers meeting the needs of customers requiring moisture management capabilities. More chemicals – and more expense – are needed to control hydrophobicity inherent in polymer quat systems.

Durability of Finish Excellent durability as organic polymer system adheres to fiber
  • Low to medium durability
  • Inorganic matrix has no attraction for the fiber surface
  • Needs binder to increase durability
  • Performance drops upon use
  • Surface charges are neutralized
  • Effects on Fabric Look and Feel No effect or slight increase in hydrophilicity Might change feel of fabric due to binder system Makes fabric hydrophobic due to the presence of long carbon chains
    Color Stability
  • No effect
  • White stays white and colorfastness maintained
  • Depending upon use level, yellowing or discoloration of white fabrics sometimes observed
  • Shade shift occurs with overtreatment
  • Potential interferences with ionic dye systems
