Material Guide: What Is Viscose and Is It ... - Good On You

Viscose is said to be the third most commonly used textile fibre in the world.If you've never heard of viscose, you may know it by another name: rayon. It's a semi-synthetic fibre that is made from trees—but that doesn't necessarily mean it's any better for the environment, or for you.

Viscose: a complete guide for brands and ... - Apparel Insider

Viscose is commonly made by dissolving wood pulp from trees such as birch, pine, and eucalyptus (although, in theory, many other cellulosic plants could be used for the process). The manufacturing process for viscose entails the wood being chipped and cooked into pulp and then dissolved in chemicals to form a pulp slurry.
