Abstract
To determin the natural dyes or color materials of acrial and ground parts of plants in various phenological stages and climatic conditions and in order to dye the natural wool an silk yarns with scientific methods, several samples of 72 plants families were collected in different appropriate seasons during several years. There are 294 samples that have been dyed according to the simultaneous dying method with 4 and 6 different mordants including Aluminium sulfate (Al.), Cupric sulfate (Cu.), Ferrous sulfate (Fe.), Chrompotaxium sulfatc (Kcr.), Nickel sullat (Ni.) and Chloride stannum (Sn.)
The production of 1520 colors in different spectres was the result. All of these colors were tested in different solutions to determine their resistance to weariness, washing. 724 colors were tested to light. Surveying on 1520 kinds of plant dyes of 294 plants with 4 and 6 Mordants during several years shows that 65-70% of the dyes are resistant to light, weariness and washing. This is a standard degree. Therefore, they can probably be used in dying the natural wool and silk yarns in Iranian carpets.
