Tussar silk

Tussar silk (alternatively spelled as tussah, tushar, tassar,[1] tussore, tasar, tussur, or tusser, and also known as (Sanskrit) kosa silk) is produced from larvae of several species of silkworms belonging to the moth genus Antheraea, including A. assamensis, A. paphia, A. pernyi, A. roylei, and A. yamamai.

[2][3] Tussar silk is valued for its rich texture and natural, deep-gold colour, and varieties are produced in many countries, including China,[4] India, Japan, and Sri Lanka.

A variation of the process exists in which the silkworms are allowed to leave before the cocoons are soaked in boiling water to soften the silk, and then the fibers are reeled.

For example, silk from larvae on the wild mulberry is called zhe, while those on the oak Quercus dentata produce hu.

[7] The saree is the most important tussar silk product[8][9] although it is also used as the base material for handicrafts, furnishing fabrics, and stitched apparel.
