Peduncle silk is a type of fiber that originates from the cocoons of wild tropical Tussah Silkworms in India. These silkworms feed on the leaves of oak trees and spin their cocoons around the branches. The first part of the cocoon is a very stiff stem, called a peduncle, which holds the cocoon in place. The peduncle is nearly black in color and has a lot of sericin, which is a sticky substance that binds the silk threads together.

Unlike other types of silk, peduncle silk is not wasted in the production process. After the moths emerge from their cocoons naturally, the peduncles are collected and processed into spinnable fiber. The processing involves soaking, boiling, washing, drying, beating, and carding the peduncles to remove the excess sericin and make them soft and lustrous. The resulting fiber is strong and durable and can be used for various purposes.

Peduncle silk is known for its unique appearance and texture. It’s less lustrous than Mulberry silk. It has a dark natural color that can be dyed with different shades. It also has a coarse and rough feel that gives it a rustic charm. Peduncle silk is mainly produced in the sub-Himalayan belt and Maharashtra, where the practice of oak tasar culture is prevalent. Peduncle silk is a rare and valuable product that showcases the diversity and richness of Indian silk.
