Henrietta
a kind of fine-twilled worsted dress goods, dyed, usually in plain colors. The original fabric closely resembles cashmere in weave, but was composed of a spun silk warp and worsted filling. At present this is called silk-warp henrietta, while a variety in which both warp and woof are of worsted is called all-wool henrietta. In weaving all-wool henrietta, nearly twice as many weft or filling threads are used to the inch as warp threads. These wefts are more loosely twisted than the warps. Consequently the filling almost entirely conceals the warp. This gives the fabric its smooth, "full-face" appearance.
