The cocoons are the raw material used for the production of silk cloth. Once selected, they are boiled in water and the threads can be separated in the unwinding stage. Each thread is between 300 and 900 metres long, which means they can be twisted together, dyed and then used to produce cloth in the weaving stage.
Overall, the diagrams show that the cocoon stage of the silkworm can be used to produce silk cloth through a very simple process.
