Abstract

Museum carpets are valuable artifacts of Iran, and moisture is one of the important environmental factors that play a significant role in the destruction of museum carpets. Moisture causes chemical deterioration and biological reactions in carpets, moisture accelerates the process of wear and fading of color. This research is of an experimental-analytical type, which has been carried out with environmental surveys, as well as library and laboratory studies, with the aim of identifying and introducing the appropriate relative moisture level for the protection of museum carpets with natural fibers of wool, cotton and silk. Therefore, to answer the question of how much moisture as an important damaging environmental factor from the perspective of preventive protection affects the tensile strength of museum carpets with natural fibers of wool, cotton and silk; The tensile strength test of the carpet along the length and width of the modeled samples has been carried out. Finally, according to the data obtained from the tensile strength test of the carpet along the length and width of the samples, it indicates that the destructive effect of moisture on the tensile strength of the carpet in it reduces by 7.830% along the length and 5.876% along the width. Analysis of variance, Tukey and LSD tests can be concluded that moisture has a destructive effect on museum carpets and reduces the tensile strength of the carpet and has a significant effect on the tensile strength of the carpets.
