Editing Moiré pattern (section)

== Etymology ==
The term originates from ''[[Moire (fabric)|moire]]'' (''moiré'' in its French adjectival form), a type of [[textile]], traditionally made of [[silk]] but now also made of [[cotton]] or [[synthetic fiber]], with a rippled or "watered" appearance. Moire, or "watered textile", is made by pressing two layers of the textile when wet. The similar but imperfect spacing of the threads creates a characteristic pattern which remains after the fabric dries.

In French, the noun ''moire'' is in use from the 17th century, for "watered silk". It was a loan of the English ''[[mohair]]'' (attested 1610). In French usage, the noun gave rise to the verb  ''moirer'', "to produce a watered textile by weaving or pressing", by the 18th century. The adjective ''moiré'' formed from this verb is in use from at least 1823.
