Product Description
Silkworm cocoon
A silkworm cocoon is the protective casing spun by silkworms during their pupal stage. Made primarily from a continuous thread of silk, the cocoon is a vital part of the silk production process. Silkworms secrete a fibrous protein called fibroin, which hardens into the silk thread as they spin their cocoon. These cocoons are harvested, boiled, and unwound to produce natural silk, which is known for its strength, luster, and softness. Silkworm cocoons have been used for centuries in textiles and continue to be a key component in luxury fabric manufacturing worldwide.
