Calendering
Calendering is a finishing process used on cloth where fabric is folded in half and passed under rollers at high temperatures and pressures. Calendering is used on fabrics such as moiré to produce its watered effect and also on cambric and some types of sateens. Process:

In preparation for calendering, the fabric is folded lengthwise with the front side, or face, inside, and stitched together along the edges.  The fabric can be folded together at full width, however this is not done as often as it is more difficult. The fabric is then run through rollers that polish the surface and make the fabric smoother and more lustrous. High temperatures and pressure are used as well. Fabrics that go through the calendering process feel thin, glossy and papery.

The calendering finish is easily destroyed, and does not last well. Washing in water destroys it, as does wear with time.
