Gauze

Woven versus non-woven

Gauze may be woven or non-woven. Woven gauze is loosely woven, usually from cotton fibers, allowing absorption or wicking of exudate and other fluids. Gauze can be woven with fine or coarse mesh; coarse gauze is useful for medical debridement, while fine gauze is better for packing wounds. Woven gauze is less absorbent than non-woven, and may leave lint in a wound, especially if cut.^[10]

Non-woven gauze is made from fibers that are pressed together rather than woven, providing better absorbency and wicking than woven gauze. Non-woven gauze is usually made from synthetic fibers such as rayon or polyester, or a blend which may include cotton. Non-woven gauze is stronger, bulkier and softer than woven gauze, and produces less lint.^[10]

Medical use

When used as a medical dressing, woven gauze is usually made of cotton. It is especially useful for dressing wounds where other fabrics might stick to the burn or laceration. Many modern medical gauzes are covered with a perforated plastic film such as Telfa or a polyblend which prevents direct contact and further minimizes wound adhesion. Also, it can be impregnated with a thick, creamy mixture of zinc oxide and calamine to promote healing, as in Unna's boot. Gauze is also used during procedures involving accidental tooth loss; either the gauze is used to provide pressure as the tooth is moved back into its corresponding socket, or the tooth is wrapped in gauze and placed in milk or saline to keep it alive while the tooth is being transported or prepared for reinsertion.^[11]

Other uses

In film and theatre, gauze is often fashioned into a scrim.

Gauze used in bookbinding is called mull, and is used in case binding to adhere the text block to the book cover.^[12]

The term wire gauze is used for woven metal sheets, for example placed on top of a Bunsen burner, or used in a safety lamp or a screen spark arrestor.
