A plain-weave fabric with a fine, smooth, crisp hand and usually a lustrous appearance. Taffeta fabric usually has a fine cross rib made by using a heavier filling yarn than warp yarn. Taffetas are produced in solid colors, yarn-dyed plaids and stripes, and prints. Changeable and moiré effects are often employed. Although originally made of silk, manufactured fibers are now often used in the production of taffeta.
