Assam silk denotes the three major types of indigenous wild silks produced in Assam—golden muga, white pat and warm eri silk. The Assam silk industry, now centered in Sualkuchi, is a labor-intensive industry.
Muga silk is the product of the silkworm Antheraea assamensis endemic to Assam. The larvae of these moths feed on som (Machilus bombycina) and sualu (Litsaea polyantha) leaves. The silk produced is known for its glossy, fine texture and durability. It was previously reported that muga silk cannot be dyed or bleached due to "low porosity", but this is incorrect; muga takes dye like any other silk. This silk can be hand washed with its lustre increasing after every wash. Very often the silk outlives its owner.
A set of mekhela chadors made with muga silk from Assam arranged around a jaapi and set on a shawl made with eri silk.
In 2015, Adarsh Gupta K of Nagaraju's research team at Centre for DNA Fingerprinting and Diagnostics, Hyderabad, India, discovered the complete sequence and the protein structure of muga silk fibroin and published it in Nature Scientific Reports.
