Rayon is manufactured using the so-called viscose process. For this purpose, sawdust is first used, which is obtained, for example, from the wood of spruce or beech, but also from woods such as bamboo and eucalyptus.
Rayon can be compared to cotton in terms of fineness and length of the fibers. Since the fibers of the fabric are made from the natural substance cellulose, the rayon fiber is less a synthetic fiber than a natural synthetic fiber or a near-natural fiber. Unlike synthetic fibers, rayon is made from the renewable raw material wood.
Compared to the production of cotton, the manufacturing process of rayon ultimately requires less water and energy.
