The weathering characteristics of cotton duck treated with copper or zinc naphthenate containing mercury naphthenate or phenyl mercury naphthenate, and the effect of weathering on the rotproofing efficacy of these treatments as judged by the soil burial method, have been investigated. The presence of the mercury compounds reduced the loss of copper during burial and did not affect the weathering properties of the treated fabrics.In an investigation of the rotproofing efficacy of binary mixtures, the naphthenates of cadmium, chromium, copper, iron, lead, mercury, silver, and zinc, containing a total of 0.2% metal, showed in general greater resistance to attack during soil burial than did samples containing the same percentage of metal in the form of single naphthenates. Ternary mixtures of the naphthenates of cadmium, copper, lead, mercury, silver, and zinc, applied to cotton fabric in equivalent concentration of total metal, were in general more effective than the binary mixtures of the same compounds. |
