Rayon is not considered a plastic. It is a semi-synthetic fiber made from cellulose, which is derived from wood pulp or other plant materials. While it shares some properties with plastic, such as being lightweight and durable, it is not made from petrochemicals like traditional plastics. Rayon is often used as a substitute for natural fibers like cotton or silk in clothing and textiles. **

To wash a shirt made of 100% Rayon, it is best to hand wash it in cold water with a gentle detergent. Avoid wringing or twisting the fabric, as Rayon is delicate and can easily stretch or lose its shape. After washing, gently squeeze out the excess water and then lay the shirt flat to dry. Avoid using a dryer, as the heat can damage the fabric. If necessary, you can also iron the shirt on a low heat setting while it is still slightly damp. **
