Jute hessian fabrics were treated with copper ammonium carbonate solution to increase its longevity. Two types of Hessians (sized and desized) were treated with various concentration of copper ammonium carbonate solution. To assess the effectiveness of copper ammonium carbonate solution as a rot proofing agent the liquor ratio, tensile strength, copper content and longevity of the treated fabrics were determined. The longevity of the treated jute fabrics were tested by exposing them to the environment in contact with wet soil as nursery pots for seedlings. The treated jute nursery pots exhibited a maximum longevity of fourteen months.
