If you are familiar with the different types of cloth that are available, you will probably come across rayon and viscose. These are two of the types of cloth that can be used for different garments. One difference is how absorbent they are. Rayon is known to be very absorbent, while viscose will not be as absorbent compared to rayon.
Another main difference is the way that they look like. When you see rayon for the first time, you will notice that it looks a bit rough. Viscose, on the other hand, will look like silk. It is only when you touch it that you will realize that it feels more like cotton.
