What is the difference between woven gauze and non-woven gauze?
Woven gauze is usually made of cotton fiber, and the weave is loose. This allows exudate and other liquids to be absorbed or wicked into or through the gauze. The woven gauze can have spun yarn or roving, which have different thread counts. Roving is usually used for debridement. When treating wounds, fine gauze is usually used as a filler. However, woven gauze is usually not the most absorbent and may leave fluff on the wound, especially in the case of a cut (this is not a good idea).
Non-woven gauze is made of fibers that are pressed together to resemble a weave. This leads to increased absorption and better wicking. Non-woven gauze is usually made of artificial fibers such as rayon, polyester or blends. This gauze is stronger, more fluffy and softer than woven gauze, and produces less fluff. However, the price of non-woven gauze tends to be higher.
