Moire
The or moiré (also Moire ; pronunciation [ mwaʀe ];. Of French moiré, moire, marbled ') is a fabric with a grain (similar to a wood grain or water waves), which is usually made of silk , viscose or synthetic fibers is manufactured. It is mostly a matter of different brightnesses, which are caused by the moiré effect of two layers of fabric placed on top of one another.
A distinction is made between real and fake moiré. With real moiré, the typical pattern is created by forcefully pressing two layers of the ribbed base fabric between heated, cylindrical rollers ( calenders ). Since the ribs are never exactly parallel, there are flatter, shiny areas at the crossing points. Since the displacement of the ribs is random, the resulting pattern is not repeated.
In the case of fake moiré, the pattern is embossed onto the fabric with the help of an appropriately patterned roller and a soft counter roller ( embossing ). A moiré effect in the strict sense of the word does not arise, but is only the basis of the press template, but the pattern changes very similarly through different incidence of light.
Papers or cardboard boxes pressed in this way with smooth, shiny surfaces are called moiré paper . Among other things, they were used as end papers or for book covers .
