Gauze is a thin, translucent fabric with a loose open weave. In technical terms, "gauze" is a weave structure in which the weft yarns are arranged in pairs and are crossed before and after each warp yarn, keeping the weft firmly in place. This weave structure is used to add stability to the fabric, which is important when using fine yarns loosely spaced. However, this weave structure can be used with any weight of yarn, and can be seen in some rustic textiles made from coarse hand-spun plant fiber yarns. Gauze is widely used for medical dressings.
Gauze can also be made of non-woven fabric.




Etymology and history


The word came into English via French gaze, beyond which its history is uncertain. The 1279 Council of Baden banned clergy from wearing "black burnet, garzatum, and all other fine cloths", and the term garças is known in Italian texts from c. 1250. Du Cange suggested connecting it to the place name Gaza (Arabic: غزة ghazza), but it is more likely to derive from Persian gazi, a thin cloth, or Arabic: قز qaz, raw silk.




Uses and types


Gauze was originally made of silk and was used for clothing. It is now used for many different things, including gauze sponges for medical purposes. Modern gauze is also made of synthetic fibers, especially when used in clothing.




= 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.
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.




= 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.




= 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.
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.
