It shows how well and how well it is. In other words, the quality of wool is the consequence of factors in which this material is used to produce good threads and textures of fine textiles and soft rugs with transparent colors and reversible Perezs, and at the same time it has enough strength and durability to have the same quality of wool properties: 1) the long and appropriate length of the same fibers is greater than cotton, and the consistency of which increases the nuance of the nuance between 2430 and the nuance of the nuance. 4) enough moisture that prevents the fragility of fibers and, however, has an average and standard limit. Softness and resistance to dry factors such as air and temperature of the environment. China and China and the wave mode in which wool fibers are originally grown.7 The elasticity and reversal and the ability of traction increases by moisture absorption. 8 Accepting the shape and flexibility that makes it possible to return to various forms in different situations such as compression, washing, exploitation, and then in the early form. This property that is desirable in Iranian sheep wool is especially important when used in carpet tissue. 9 Strength and resistance, which, according to the physical situation in the wool fibers, is more common than other fibers.10 The shape of the external skin that is falsified and gives the fiber of the property. 11 The brightness and transparency of the color that increases even by time and friction. 12 Attraction of moisture, which, as usually moisture, increases the elasticity of the wool fibers, adds to the quality of the wool. Warming and electricity and some other desirable physical and chemical characteristics.14 The health of fibers that this feature occurs as a result of the presence of the above mentioned properties in wool fibers and makes it less vulnerable than the same fibers.
