moiré

moiré


engraved finishing technique


Definition:

A finishing process that produces a wavy or rippling pattern with engraved rollers that press the design into the fabric. The difference in reflection of the rays of light form the uncrushed and crushed parts of the design result in the moiré effect. It is usually applied to ribbed fabrics of cotton, acetate, rayon, silk, and some manufactured fiber fabrics, and is not permanent unless heat set or chemically set. Originally indicated a watered design like watermarks on paper.
