The existing standards for measuring carpet properties consider carpet behavior after loading while its dynamic and instantaneous behavior is neglected. To investigate the dynamic behavior of under loading carpets, an INSTRON machine equipped with a developed system was used. The reliability of the system was verified by testing different materials. Different samples of hand-knitted carpet with 30, 40, 50, 60 and 70 Raj (rows/6.5cm), with specific structural and physical characteristic and raw material, were tested to obtain the curves of their pressure resistance versus time. The relation between features derived from the load/time curves and carpet structural and physical characteristics and raw materials were defined. Measuring the Pearson coefficient correlation, the linear correlations were studied and analyzed. The results indicate that with increase in knot density (Raj), the rate of decreasing thickness during loading, the resilience of carpet pile after loading, the total work exerted to carpet for reaching to jamming phase and the work returned by carpet during recovery phase decrease; while with increase in carpet thickness, the resilience and the total work increase. In addition, the load/time curves of different materials and hand-knitted carpets were compared. The similarities and differences between their behaviors were derived and the desirable compressibility behavior of a carpet is accordingly suggested.

The compilation of subject matter and data used in this article are extracted from library and recorded materials based on historical and pictorial sources to show changes in Kelardasht carpet within the past 100 years. Furthermore interviewing with masters in museums and bazaar was also used in accomplishing this article, and at the end data and pictures were compared to study the design and patterns of Kelardasht carpet in order to classify the patterns and motifs of these subjective and mental-woven carpets. Study of variations of patterns, motifs and colors in Kelardasht carpet shows that most of the patterns have been forgotten in the course of time and are not used any more. Then because this carpet is not a commercial one, difficult access to the area and entering poor patterns, this carpet was undermined or even defeated. It seems that the usage of old and original colors, original patterns and motifs and introducing genuineness and employed concepts in this kind of carpet to young people and buyers are important factors for the revival of Kelardasht carpets.

The aim of this research is assessing carpet weaver's health needs and designing a model for meeting them. A sample of 1688 carpet weaver in 8 provinces (Azarbijan, Fars, Kerman, Markazi, Kordestan, Golestan, Mazandaran and Khorasan) has been interviewed for collecting research data. Findings show that a Persian carpet weaver in Iran is typically a thirty-one aged, married woman with three children who works seven hours a day. She has not another paid work and says that she weaves out of necessity. Regarding health habits, the research shows that 51% rest between work times, 14% exercise, 13%brush, 17% wash their hands with soap before dine and after going to toilet and only 6% use masks. Other results of the research indicate that health and medical facilities available for the population is not satisfactory in comparison to national rates. The carpet weavers' accesses to health and medical possibilities are as: 65% to physicians and medical centers, 79% to water supply, and 85% to bath. Also, 10% of them have social security insurance and 50% have rural medical insurance. 48% of respondents have attended health education programs and their information about issues of workshops' health needs and meeting them were satisfactory. 60% of workshops have other uses too, for example as kitchen, dining or guest rooms.

One of major issues of the countries, especially developing countries, is expanding globalization process and the way of facing with it. Globalization is not a process that be encountered similarly in all countries but those who recognize its all aspects could utilize more and make better use of opportunities it makes; consequently, they could compete well in international community. Knowing competitive and comparative advantages of different sectors of country's economics can be a significant change to the rising of competitiveness. Since the hand-knitted carpet industry is one of the sectors that promise high non-oil export potentials, this paper concentrates on this industry and utilizes the Policy Analysis Matrix (PAM) to calculate indexes of competitiveness and comparative advantage in the hand-knitted carpet industry. As the province of Qom is one of the major producers of high quality marketable carpets, the paper concentrates on this area. The province has a long history of producing unique carpets in terms of design, weaving quality, coloring and other qualities. At present, Qom stands ready to supply the export market with enough of 65 knots hand-knitted silk carpets. So for evaluating trade globalization's effects on hand-knitted carpet industry, we use data and information about that kind of carpet in 1385. Results show that the index of the competitiveness of Qom hand-knitted silk carpets is 93% and its comparative advantage based on unit cost that would hold when Iran joins WTO is 84%. These indexes indicate that Qom hand-knitted silk carpets score high both in terms of competitiveness and comparative advantage.

One of the pre-treatment processes on silk is degumming that has much influences on other processing. There are various degumming methods and each one has its own advantages and disadvantages. In this research protease (Alkalase) and Keliab (remaining ashes of "Oshnow" plant obtained from Qom, Yazd and Kashan) used as environmentally friendly compounds for degumming of silk. Different concentration of enzyme with soda ash and surfactant and also Keliab were examined. Some properties of degummed samples such as weigh loss, strength, lightness and whiteness were tested and surface morphology also was observed by SEM. The degummed yams then dyed with madder, using two types of mordant namely stannous chloride (SnC12) and aluminium-potassium sulphate AlK(SO4) 2. The color coordinates L*a*b* and washing fastness and light fastness of samples were evaluated. The results showed that weigh loss percentages, strength and whiteness of samples varied due to degumming with Alkalase and Keliab. However, washing fastness and light fastness of madder dyed samples were acceptable.

A new trend of weaving pictures in Qajar era is considered to be a revolution in the art of carpet-weaving whether from viewpoint of form or concept. These pictorial rugs were intended to be spread on the floor no more, but they were woven for visual satisfaction, exactly as pictures. These pictures are like an encyclopedia of the cultural life of that era, which covers beliefs, culture and life of the people and can be employed for discovering unknown aspects of their culture and outlook. This paper has amid to understand and find the meaning of one of these rugs, namely "Mary and Jesus Christ" by analyzing it using Erwin Panofsky's iconographic method for finding different meaning layers. The paper concludes that the above-mentioned rug has the function of an icon and for fulfilling its "monumental" and "didactic" objectives makes use of Islam doctrine, Qoran's verses and Iranian mystical art and literature. At the end, in search of deep and concealed meanings of this icon hidden beneath its different meaning layers and for finding its "artistic desire" and cultural reasons for its creation, this article shows the votive objective of this rug as a means of obtaining offspring and conforms the public's belief in miraculous power of the icon.

Iranian carpet has an allegorical and symbolic sense of heaven and heaven-like gardens which is similar to the descriptions in the Holy Qoran, yet the existing plans and sketches in heaven-like carpets are proportionate to Iranian garden's design and architecture (especially the Char-Bagh) in the way that it draws an everlasting picture of infinite world and heaven gardens in this world. In Islamic culture the growing path of human is from carpet to the empyrean, human beings come to the world on the carpet and fly to the empyrean and in its highest levels they lean on the best carpets made of silk in the heaven. Based on this research, it has been shown that an allegorical concept of heaven and its gardens in Iranian carpet can be found completely, which are full of Islamic gardens showing the high potentials of Iranian carpet designers in drawing and designing heaven's spiritual concepts to weave the strings in a way that they deserve the holy concepts and remind us the everlasting heavens which ties us up to the infinite existence of it.
