The history of fibers is as old as human civilization. Traces of natural fibers have been located to ancient civilizations all over the gob. For many thousand years, the usage of fiber was limited by natural fibers such as flax, cotton, silk, wool and plant fibers for different applications. Fibers can be divided into natural fibers and man-made or chemical fibers. Flax is considered to be the oldest and the most used natural fiber since ancient times.
