Linen is a fabric made with fiber extracted from the flax plant. The oldest flax fiber used by humans goes back 36,000 years. There are about 200 flax species worldwide, most of which are wild. The peoples of Central Asia, Egypt, Greece and Gaul used flax fiber and have fostered the development of a flax species known as “usitatissimum.” Historically, linen was one of the most popular textile fibers until the late seventeenth century. Thereafter, cotton was introduced and gradually replaced linen. Linen now represents only 0.3% of all textiles produced worldwide, but its ecological value and its noble and natural character make it a sought-after fiber.
