What is considered the oldest known carpet fiber?

Wool is considered the oldest known carpet fiber due to its widespread use throughout history, particularly in ancient civilizations. Archaeological evidence shows that wool has been utilized for textile production for thousands of years, with some of the oldest surviving carpets and textiles discovered dating back to around 600 BC, which were found in regions such as Persia and Turkey.

Wool's natural properties make it an advantageous material for carpets. It is durable, resilient, and has excellent insulating properties, which contribute to its longevity. Additionally, wool is naturally stained-resistant and has the ability to absorb moisture, which helps maintain its appearance over time. These characteristics have made wool a preferred choice for high-quality carpets for centuries, allowing it to hold a significant place in the history of carpet manufacturing.

Other natural fibers like silk, cotton, and jute have their uses and historical importance, but wool's early and extensive application in carpet making secures its recognition as the most ancient carpet fiber.
