Study of side effects of Thiophanate-methyl fungicide on aesthetic and structural properties of ‎paper

Abstract

‎ The most of the fungicide‏ ‏that are used to prevent or stop the biological destruction of the historical papers have been used ‎at the first time in domains of science and industrial So thiophanate methyl which is most useful in agriculture, have been ‎tested in repairing and protection of papers and it’s one of the most useful materials in agriculture antifungals.The main ‎aim of this research was assessment of aesthetic and structural effects on paper after treatment by Thiophanate-methyl ‎compound. Experimental method (laboratory experience) and library study wre applied in this research. ATR-FTIR spectra ‎showed that spray of Thiophanate-methyl on paper did not produce any degradation effect. The compound had not ‎changed aesthetical properties and pH values. Tensile strength of paper did not reduce due to the treatment. This indicates ‎nondestructive effects of Thiophanate-methyl on paper which signifies its great capability for application in conservation ‎and restoration of paper.
