SILVADUR Delivers Long Lasting Antimicrobial Protection

Antimicrobial Efficacy & Wash Durability

SILVADUR™ Durability
Types of Tee Shirts % Reduction of Escherichia coli
  Unwashed Washed 50x
100% Cotton Tee Shirt 99.99% >99.0%
50/50 Polyester/Cotton 99.99% >99.5%

SILVADUR treated fabrics were tested vs. a control (untested) fabric and measured for overall reduction in bacteria.


Fabrics were tested using ISO 20743 Test Method with Escherichia coli (ATCC 25922).


Tests independently performed by the International Antimicrobial Council
