Rayon is a type of fabric made from processed wood pulp. It is soft and lightweight, and is often used to make clothing, bedding, and other items. Rayon fabric is popular because it is affordable, easy to dye, and has a soft, smooth texture. It is also highly absorbent and breathable, making it ideal for hot weather. Rayon is often blended with other fabrics to create a more durable, wrinkle-resistant fabric.
