Museum carpets are one of the valuable works of Iran and humidity is one of the important environmental factors that plays an important role in the destruction of museum carpets. Moisture causes chemical spoilage and biological reactions in carpets, moisture accelerates the process of color wear and paleness. This research is an experimental-analytical type that has been done with environmental studies as well as library and laboratory studies with the aim of recognizing and introducing the appropriate relative humidity 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 harmful 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 in terms of length and width is performed on the modeled samples. Finally, according to the data obtained from the tensile strength test of the carpet in terms of length and width of the samples, it indicates that the destructive effect of moisture on The tensile strength of the carpet decreases by 7.830% in length and 5.876% in 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 carpets and has a significant effect on the tensile strength of carpets.
