It is from natural and animal and protein that is soft and transparent and solid, and the use of textures of fine textiles and carpets. Silk is one of the most important fibers in the textile industry. This important material is drawn into a very thin thread in two disciplines and is discharged from the gland glands of the silkworm; the silk stripes the fibers at the other time (change of states in the direction of evolution) into its course as two layers, which makes a whole form of cohea. For the use of silk fibers, before the cream is ready to be removed from the Pilate, they cook it after the classification, which place the Pilate in warm water (60) degrees. The worm dies inside the Pilate, and the plumin becomes soft, and the pure and non-foreign fibers remain, yet they collect small frustrations with the special toolkit. Silk has a variety of different types of silk, and some have argued that silk has been discovered and nurtured in its history and voyages of silk in most parts of Iran, and some say that silk for the first time in Iran, and it is used to obtain the flos and textures of textiles and carpets without regard to the birthplace of silk, Iranians can be compared to the oldest and most sensitive materials. Now in the world it takes place on the silkworm race in order to receive greater returns of various research, and this is done more seriously in India and Japan than in other countries and consistently, the artificial silkal material is also available in the market, and those dealing with this precious material must fully recognize natural silk from it. In this book, part of the ways of distinguishing these two species under the title of silk-identification, the silk hole in Peres is used in the tariff of the delicate carpets of different parts of our country, in accordance with its elegance and strength in raising the quality and quality of the Iranian rug, and with silk carpets needing expertise and now only few countries can produce such carpets. In Iran, these types of carpets are mostly woven in the valley, Nain, Saphins, Perseparate, and the amount of texture is much lower than other carpets. In the provinces of Khorasan and Gilan and some other parts of the silkworm breeding factories called New Orleans. These factories are employed every year in the appropriate seasons, spring and summer, and sometimes silk. The silk product of different cities is used in local silk factories, and the other part is taken to other areas for various exploitation, including consumption in the rug and textile industry.
