Gros-Grain (Gro'-Grain). [From gros, thick, and grain, grain, showing conclusively the origin of the word and the manner of fabrics they should be]. A firm, close-woven, fine-corded or grained dress silk, finished with but a slight lustre. The earliest grosgrain fabrics were woven with a silk warp and a mohair weft, and were very coarse. These were known at different times under the terms " grogram " and " silk mohair." [See Silk]
