What material is primarily used for cohesive elastic bandages?

Cohesive elastic bandages are primarily made from a blend of rayon and spandex. This combination allows the bandages to have the necessary elasticity and stretch while ensuring a secure grip without slipping. The rayon provides softness and comfort, making it easier to wear for extended periods, while spandex contributes to the elasticity needed for compression and support.

The use of this specific material blend is crucial for ensuring that the bandage conforms well to the contours of the body, providing stability to injured areas while allowing for some degree of movement. Additionally, rayon and spandex bandages adhere to themselves rather than to the skin or clothing, which minimizes the risk of irritation or allergic reactions. This characteristic makes them particularly advantageous in athletic settings, where a secure but flexible support is essential for injury prevention and recovery.
