Sayette (Sa-Et'). [From It. saiette serge] A light fabric made of fine wool and silk; it is a species of serge, adapted for linings, furniture-coverings, and the like. Also, this name is applied to a kind of woolen yarn, intermediate in quality between combed yarn and carded yarn. A long wool is used, but instead of being combed it is carded on a mill of peculiar construction. It is used in making stockings, carpets, and Berlin wool work. Also called half-worsted yarn.
