Early materials of carpets, especially wool, silk, cotton, are stuck and vulnerable in the production and storage phase. In such a way that they have not been able to do so, and they have no harm on it, they are responsible for the duties of carpet manufacturers and their factors in order to produce no fault. In small and home workshops and in villages and between tribes and Ills, which fortunately produce more than half of the country’s carpets, they usually produce and produce the seeds of the materials that they or their neighbors. They use it, and this way they are completely in the health of these substances, and given that the storage issue is not so important, the accuracy of primary materials is not so important. But in large workshops where these materials are purchased from the market and strangers, or even from other countries and nations, and the possibility of a variety of defects goes by buying agents and supervisors of workshops, they need to pay attention to the health of the materials and buy it completely to avoid irreparable losses that may be prevented from producing carpets. The drawbacks of raw materials are usually: 1) natural material defects such as that “flame” are somehow less fat than usual wind and dry or cotton has not reached or halved or harmful fungi. • Errors imported by warehouse or mistransmittance such as “disease” etc. (3) The defects that the workers’ hands insert, such as placing it in the vicinity of harmful chemicals or dirty and metal containers. The rug woven with the raw materials that have the above defects does not have enough durability and endurance, and secondly, after a little while, it has a dislocation or two coloring and styling and totaling, etc.
