Rayon is a manufactured fiber made from regenerated cellulose derived from plant materials such as bamboo. Rayon fabrics are very soft and breathable. As one of the worldâs oldest manufactured fibers, rayon is used for a variety of textiles including underwear.Most underwear manufacturers mix with rayon with other fabric blends to achieve a stretchable fit.ayon is a manufactured fiber made from regenerated cellulose derived from plant materials such as bamboo.

Because rayon is manufactured from naturally occurring polymers, it is considered a semi-synthetic fiber. Specific types of rayon include viscose, modal and lyocell, each of which differs in manufacturing process and properties of the finished product.uprammonium rayon has properties similar to viscose but during production, the cellulose is combined with copper and ammonia (Schweizer's reagent). Due to the environmental effects of this production method, cuprammonium rayon is no longer produced in the United States.
