Gauze is a thin, translucent fabric with a 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 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 was traditionally woven in Palestine and the English word is said to derive from the place name for Gaza (Arabic: غزة ghazza), a center of weaving in the region. Despite a prohibition on trade with non-Christians from religious authorities in medieval Europe, a fine type of silk known as gazzatum was imported from Gaza as early as the 13th century. Though members of religious orders in Europe were forbidden to wear it, the fabric won a place for itself and emerged into modern life as gauze.
According to the French government's online etymology dictionary, the English form of the word derived from the French gaze, whose ultimate origin is uncertain, but is often attributed to the Arabic and Persian word qazz meaning "raw silk", which itself was obtained from the name of Gaza. The same source says the existence of "an ancient textile industry in Gaza is not assured," and it is not known how the word entered into widespread use in European languages, with examples of first usages cited being the medieval Latin forms garza in Bologna in 1250 and gazzatum in Budapest in 1279.
Gauze was originally made of silk and was used for clothing.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. When used as a medical dressing, gauze is generally 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 plastic porous 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.
