Viscose, Modal, and Tencel are all types of rayon, a synthetic fabric made from natural fibers. However, there are some differences between these three materials.

Viscose is a type of rayon that has a silky feel and a fluid drape. It’s often used to make lightweight clothing, like summer dresses and blouses, because it’s breathable and cool to the touch.

Modal is another type of rayon that’s known for its softness and moisture-wicking properties. It’s often used to make underwear and loungewear because it’s gentle against the skin.

Tencel, also known as lyocell, is a newer type of rayon that’s made from wood pulp from sustainable tree farms. It’s known for being environmentally friendly, as well as for its smooth and soft texture. It’s often used to make clothing items that are close to the skin, like shirts and pants, because it has a luxurious feel.

In conclusion, Viscose, Modal, and Tencel are different types of rayon with distinct properties, but all of them are soft, breathable and comfortable to wear, making them popular choices for clothing.
