Tussor silk fabric, also known as 'Kosa silk' in Sanskrit, is valued for its purity and texture.
Tussor silk fabric has natural shades of gold-pale, dark, honey, tawny, creamy, etc. but it also goes well with dye. It is generally dyed with natural dyes.
Tussor silk is produced from silkworms like Antheraea mylitta, Antheraca proylei, Antherea pernyi and Antheraca yamamai. These worms are wild and feed on the leaves of Arjuna (Terminatra), Asan (Terminatia Tementosa), Saja or Sal trees. The silkworms spin a single-shelled, the oval cocoon, which is generally yellow or gray and are hard and compact. The shells of the cocoon are fine-grained and non-flossy. The cocoons are boiled to make it soft and the yarn is then reeled.
