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
tensile strength. Moreover, making wool fabrics antibacterial is a considerable task for protection of fabrics and consumers against microbial attack and growth. In this research nano-silver was synthesized using reduction of silver nitrate by sodium bisulfite along with increasing the fiber fineness using tensile. This process was successfully introduced Iranian coarse wool yarns with loading of nano-silver through in situ synthesis and consequently, suitable antibacterial properties along with some other improved properties such as yarn tenacity and improvement of yarn count were obtained. Subsequently, SEM and EDX analyses confirmed the nano-silver synthesis on the wool yarns and indicated the importance of test conditions on antibacterial properties of the fibers.

Abstract
Today, the use of enzymes and antibacterial protein fibers is greatly favored by researchers to protect textile against microbial attacks, spots, discoloration and to increase shelf life of silk carpets in museums. This study investigates the effect of protease and nanosilver on silk yarn. Silk yarn with 140 Tex as a carpet pile treated with protease and nanosilver in different conditions and their antimicrobial properties against two bacteria, i.e. Escherichia coli and Staphylococcus aureus was studied and compared. Also, some characteristics of products including weight loss, whiteness index and color indices, have been investigated in SEM images. Using nanosilver alone showed excellent antimicrobial properties against microbes with different concentrations while reduced the whiteness of silk yarn. However, using 2% protease led to enhanced antibacterial properties, and whiteness. On these bases, concurrent use of protease and 30 ppm of nanosilver produced silk yarn with excellent antibacterial properties i.e. 100% bacterial reduction.

Abstract
After the arrival of Islam and the prohibition of the use of animals and human figures, the Islamic artists invented new and different manners to decorate various art forms; one of this way was applying different calligraphy styles in their pieces. The carpet was one those which got influenced by calligraphy
This investigation will study the importance of writing and calligraphy; and the factors, which influence on the quality and execution of rules and geometry of writing in carpet through analyzing the collected samples and a descriptive-analytical manner. It is well known that the carpet, in comparison with the other branches of art, has a limitation in execution and techniques especially in design. This investigation has analyzed the samples up to Qajar period while considering the technical limitations as the main obstacle for the lack of executing the letters in calligraphy although with utmost beauty and maturity, and also taking into consideration that the use of writing as a subsidiary factor, leads to less attention to its execution. Eventually, it is concluded that the technical limitation, in some cases human mistakes, neglect and imprecision were factors, which had influence on execution of the carpet.
Between different types of writing, Nastaliq was the only script, which has received most infliction in both execution form and technical points.

Abstract
Nowadays, the status of e-commerce in the exchange of art works is the subject of study experts in the field of art economics. Considering the importance of this issue, identifying the effective factors in accepting e-commerce in this sector of the economy is essential. Hence, using this technology in the art sector, especially the handmade carpet exchanges, we can overcome the problems in the handmade carpet economy and achieve the positive outcomes in the field of economy with the support of handmade carpets, owing to its effective role in the Iran's economy.The present research aims to find an answer for the following questions: 1. How can e-commerce contribute in development of the economy based on handmade carpets and related factors? 2. What infrastructures are needed to use e-commerce for the development of the economy based on handmade carpets?Thus, the objective of the present study is to evaluate the benefits of using e-commerce to develop the handmade carpet economy in Iran and identify the effective infrastructures in accepting e-commerce and exploiting it in the development of the economy based on handmade carpets. The research method in this study is descriptive-survey. Library resources, valid internet websites and questionnaires were used to collect the data. This research investigates e-commerce, art economics and handmade carpets. Then, research results are presented by analyzing the data. Finally, some recommendations are presented to achieve the research goals and future research. Based on the results of this study, creating a cultural and educational context for handmade carpet authorities and creating the necessary infrastructure for accepting e-commerce would be of great contribution in the development of handmade carpet exchanges.

Abstract
both The art of keeping it all in the And increase staff productivity The art of imitation by competitors is Model is based on industrial cluster. The aim of this study is That with the study of participants perceptions and beliefs To identify barriers factors to the formation of industrial clusters should Khorasan Carpet. In this study, Q methodology was used as an integrated approach. Participants in this study is 10 cases of managers, and producers of Khorasan Carpet. Were positively associated with research. This discourse space Have been collected from various sources After evaluating and summarizing the discussion Among the 134 Meter 52 For example, the following SQL statements (batch Q) The opinions of experts were. After collecting data from SQL sorting The data were analyzed using Q factor analysis. Distribution analysis showed that Paradigm can be 3 Distinct (Lack of appropriate infrastructure support and Lack of support and supplementary units, Terms weavers) Participants in the study Barriers to the formation of industrial clusters in North Khorasan Carpet Identified Approximately 62.8% of the total Of the total variance explained. Importance and priority barriers identified Patterns were obtained in based on subjective pattern and finally proposed some ways for omitting Identified pattern In order to implement the model of industrial clusters in the carpet industry
