Viscose fabric, also known as rayon, is a semi-synthetic material made from natural wood sources such as eucalyptus, beech, and pine, as well as plants such as bamboo, soy, and sugar cane. The cellulose material is dissolved in a chemical solution to produce a pulpy viscous substance, which is then spun into fibers that can be made into threads. While viscose is derived from natural materials, it is a heavily processed fabric that uses chemicals such as carbon disulphide and sodium hydroxide in its production. Viscose is often used as a silk substitute due to its similarities in drape and texture, and it is a popular and inexpensive way to produce different types of clothing. However, there are concerns about its production and long-term sustainability as a fabric option, and many clothing producers are taking steps to create cleaner and greener processes.
