Semisynthetic fabrics, also known as rayons (6 letters), are fabrics made from natural and synthetic materials. They are produced by chemically treating natural materials such as wood pulp, cotton, or bamboo to create a fabric with a unique texture and feel. Rayons are often used in clothing and home furnishings due to their softness and durability. They are also often used in medical applications due to their hypoallergenic properties.
