Non-woven gauze is made from synthetic fibers like rayon or polyester and is pressed together to resemble a weave pattern. It tends to be thicker, stronger, and softer than woven gauze. Non-woven gauze does not product lint, making it more suitable for direct wound contact. Non-woven gauze provides superior absorption and wicks moisture away from the wound site to prevent maceration. Keep in mind that some non-woven gauze is sterile, while others are not. If you will be using non-woven gauze directly on an open wound, it is ideal to use a sterile variety.
