Natural Wools are the main material used in carpets. However, cotton, silk, goat hair, camel hair and and occasionally precious metals such as silver, gold and copper threads are also used in making an oriental rug.
Several factors determine the quality of wool in a carpet:
- Climate is of utmost importance, as well as the diet of the sheep, the chemical composition of the water, and the altitude at which the sheep have lived and grazed.
- The age and the part of sheep from which the wool is taken.
- The softest and most luxurious wool is obtained by combining the young sheep in winter time, and is known as Kurk wool.
- The wool from the shanks and belly is also very lustrous and pliable
