Serge (fabric) Serge (fabric) Serge is a type of twill fabric that has diagonal lines or ridges on both sides, made with a two-up, two-down weave. The worsted variety is used in making military uniforms, suits, great coats and trench coats. Its counterpart, silk serge, is used for linings. French serge is a softer, finer variety. The word is also used for a high quality woolen woven fabric. The name is derived from Old French , itself from Latin , from Greek ("serikos"), meaning "silken". The early association of silk serge, Greece, and France is shown by the discovery in Charlemagne's tomb
Moire (fabric) threads in places, thereby forming a surface which reflects light differently. The weft threads also are moved slightly. "Changeable moire" is a term for fabric with a warp of one color and a weft of another, which gives different effects in different lights. Moire fabric is more delicate than fabric of the same type that has not gone through the calendering process. Also, contact with water removes the watermark and causes staining. Moire feels thin, glossy and papery due to the calendering process. Generally moire is made out of fabrics with a good body and defined ribs, such as grosgrain.
