Gauze is a lightweight, thin, and breathable fabric made from cotton or a cotton blend. Its primary use is in medical settings, where it serves as a protective covering for wounds. The material comes in various sizes and can be found as sterile or non-sterile gauze pads, rolls, or strips. Due to its porous nature, gauze allows air circulation to the wound while absorbing drainage, which helps facilitate the healing process. Gauze can also be utilized for various purposes beyond medical applications, including crafts and filters in laboratory settings.
