Vanya silk
The group name in India for silks other than mulberry, which is tussar, muga and eri, from worms that feed on forest trees and plants.
Also: wild silk, non-mulberry silk
Vanya means wild or of the forest. In Indian silk trade and in the Central Silk Board's usage, vanya silks are those from worms that do not feed on mulberry. The three main ones are tussar, from the central and eastern forest belt, muga, from Assam, and eri, from Assam and nearby hill states. The worms of these silks live on trees and plants that grow in the wild or in small plantations. The threads are usually thicker, more textured and less uniform than mulberry silk, and they take natural colour and dye in different ways.
