Viscose is synonymous with rayon, and the name comes from the honey-like texture that occurs during the manufacturing process. The main ingredient in viscose is wood pulp, making it hard to classify as either synthetic or natural. Though the wood pulp makes it natural, the manufacturing process (a very polluting one) is very much driven by man.
Advantages:
However, like any other fabric, viscose isn’t without its disadvantages.
These disadvantages are the main reason I only use truly natural fabrics like cotton and silk in my collection.
In my own experience, viscose and rayon are most appreciated in a fabric blend. I have worked with linen/rayon blends that drape beautifully due to the nature of the rayon, as 100% linen is a rather crisp fabric. Together, they make up where the other one lacks.
