Tussar

Tussah (also called Tussar, Tasar, Tussore) is a medium to heavy weight silk made from free-range (Woo Hoo) wild silkworms of the Antheraeamylitta or Antheracaproylei species. The warp and weft yarns of this plain weave silk fabric are very different, giving tussah the look of woven grasses. Tussah is relatively uneven, has small lumps and is less lustrous than cultivated silk. It does however tend to be stronger, perhaps because it is a somewhat thicker fiber. Because of tannin-rich diet, Tussah is almost always a natural brown color. But it does dye well, and is good for suits, jackets, and home decoration.Sews easily but may unravel, so finished seams are advisable.The name Tussah is also associated with the Antheraea silk producing caterpillar. This caterpillar is raised in the forested regions of China, Korea and India, and has a different diet from its Bombyxmori cousin – relying mostly on Arjun tree (terminaliaarjun), Asan (terminaliatomentosa), and Oak (querus). Tussah silkworms are protected and harvested in jungles and forests by indigenous peoples in Asia. These silkworms seem to have rejected all attempts at total domestication. Tussah fibers are derived from cocoons collected after the moth has emerged naturally in the field, and are a little coarser than the cultivated Bombyxmori. Whether they are reared in the tropics or temperate climate, the leaves they eat contain tannin, the ingredient in tea that leaves a stain in your cup. The natural color of tussah silk is, therefore, warm honey beige.
