Moire, less often moiré, is a textile with a wavy (watered) appearance produced mainly from silk, but also wool, cotton and rayon. The watered appearance is usually created by the finishing technique called calendering. Moiré effects are also achieved by certain weaves, such as varying the tension in the warp and weft of the weave. Silk treated in this way is sometimes called watered silk.

In textile manufacturing, finishing refers to the processes that convert the woven or knitted cloth into a usable material and more specifically to any process performed after dyeing the yarn or fabric to improve the look, performance, or "hand" (feel) of the finish textile or clothing. The precise meaning depends on context.
