Rayon is considered semi-synthetic. The raw ingredient, usually wood pulp, is natural, but the processes used to refine it stop it from being classified as such. It’s the closest replica to silk, and very soft. Mostly used in dresses and blouses, it's also found in loose-fitting sportswear, like tank tops and t-shirts.
