Rayon is semi- synthetic and therefore has both durable and less durable sides. The fabric is biodegradable and is made from renewable raw materials, namely cellulose from wood. Therefore the production of the rayon fabric does not contribute to the plastic soup. The production of viscose also costs less water than the production of cotton, for example. Rayon is also a strong fabric that lasts a long time. However, there are also a few downsides to the rayon fabric in terms of durability. For example, many chemicals are used in the production of the fabric. Also, much of the wood used for rayon comes from endangered jungles. Rayon fares better with these characteristics than, for example, silk, but there are certainly more sustainable alternatives, such as Tencel.
