Moire (fabric)

Moiré (also: Moire, from French moirer [ mwaʀe ], " moirieren; marbling ") is a fabric with a grain (similar to a wood grain or water waves), which is usually made of silk, rayon or synthetic fibers. There usually are different brightnesses, which result from the moire effect of two superposed layers of fabric.

We distinguish between genuine and spurious moire. When real Moiré the typical pattern image is generated by successive presses of two layers of corrugated starting tissue between heated, cylindrical rollers ( calender) vigorously. Since the ribs are not exactly parallel, develop flatter, shiny patches at the crossing points. Since the displacement of the ribs is random, the pattern thus formed is not repeated.

When spurious moire pattern is characterized by a corresponding patterned roll and a soft backing roll on the fabric ( embossing ). A moiré effect in the strict sense is not created, but is merely the press template based, by different light, the pattern changes but very similar.

Such pressed paper or cardboard with smooth, glossy surfaces are referred to as moire paper. They found, among other things as end papers, or use for book covers.
