Moire is a fabric with a wavy surface pattern that is produced by engraved rollers; differences in surface light reflection result in a soft luster. Faille is a fabric with a light, cross-grain rib made by using heavier yarn in the weft than in the warp. The durability of these fabrics depends on fiber content, weave construction, and finishes. Heat-setting or resin finishing can increase the durability of the fabric. For both moire and faille, dry cleaning is preferable. These fabrics can usually withstand a five to seven minute dry cleaning cycle and can be dried at 120-140°C.
