This report contains the results of studies performed to evaluate the rot and weather-resistance protection provided by copper-zirconium and Zirchrome as finishes for cotton textiles. Cotton fabrics treated with either copper borate-zirconyl ammonium carbonate Cu-Zr or Zirchrome were subjected to rot- resistance and weathering tests. The Cu-Zr finish provided good microbiological protection relative to copper 8-quinoinolate, but there were several instances of loss of protection after leaching or Weather-Ometer exposure and accelerated fabric degradation after weathering. The Zirchrome finish, though inferior in microbiological protection and durability of protection to the Cu-Zr finish, was as protective as the MIL-M-46032 cuprammonium finish but caused a large tearing strength loss on application of treatment to cotton osnaburg.
