The diagrams display the life cycle of the silkworm and the process of producing silk cloth through the use of cocoons.
The life cycle starts when female moths lay eggs on mulberry leaves, and after 10 days, the larvae hatch from the eggs. Within 4-6 weeks, the silkworm larvae eat the mulberry leaves and form silk thread shells. The larvae remain in the silk thread shell for the next 3–8 days, creating an oval cocoon. The final stage lasts for 16 days, during which the silk moth appears from the cocoon and the cycle restarts.
For the production of silk cloth, selected cocoons are boiled in water. Then, about 300–900-metre threads are produced by unwinding the cocoons. These threads undergo twisting, dyeing, and weaving to manufacture the final silk cloth product.
Overall, the life cycle of a silkworm has four stages, beginning with the laying of eggs by the silk moth and ending with the formation of the silk cocoon. Whereas, the production of silk cloth involves the selection of cocoons, boiling them, and unwinding to create silk threads from which the silk cloths are made.
