Abstract
Special properties of Iranian wool such as elasticity compared with Merino wool leads to more popularity of Persian carpet at an international level. By using of finishing process it is possible to improve some of the physical properties of wool fibers such as fleece modification, increasing of lightness and whiteness and producing a smoother surface that result a better quality carpet. In this research influence of proteases on Iranian wool was investigated and variation in concentration and time was optimized. The results indicated that increasing of enzyme leads to increasing of loss of weight, strength and strain. With prolonged enzymatic processing it may obtain better whiteness, lightness, and bending. Changes in whiteness, bending and fineness and other properties such as weight loss, strength reduction and strain would be discussed.

Abstract
The Iranian Carpet Museum collection contains the most valuable specimens of rugs from the ninth century AH to the contemporary period and is a rich source of research for researchers and art friends. Carpet Museum carpets and carpets, according to their quality and antiquity and taking into account the characteristics of carpet in terms of color, design, role, texture and variety of carpet weaving areas are preserved. The museum is built on two floors, the first floor of which is a permanent display of 150 pieces of carpet and the second floor is intended for specialized and seasonal exhibitions.
In this empirical-analytical study with environmental studies, sampling as well as library and laboratory studies, we have identified and introduced appropriate light levels for the storage of museum carpets with natural fibers, thus In order to perform tensile strength test of museum carpets because it is not possible to perform tests on museum rugs and it is necessary to fabricate rugs in accordance with the statistical population studied, weave samples of natural fibers of wool, cotton and Silk is done. Finally, according to the data obtained from the test of tensile strength of carpet in line with the length and width of the samples, analysis of variance, Toki and LSD tests can be concluded that light has a destructive effect on the carpet and reduces the tensile strength of the carpet and It has a significant effect on the tensile strength of carpets.
