Anotations

Scope note:

Silk fibers produced by any of several species of larvae of the genus Antheraea, primarily found in China and India. The filaments of tussah silk are coarser and stronger than silk fibers from cultivated silk worms. It is rarely weighted. Wild silk is brownish and more difficult to bleach, so it is usually dyed in dark colors.
