The given diagrams illustrate the life cycle of the silkworm and how the silk cloth is made.
Overall, it is readily apparent that there are four main stages in the life cycle: egg, larva, cocoon, and adult moth, and the production includes five steps: selecting, boiling, unwinding, twisting, and weaving.
The life cycle begins with a female moth laying eggs and after 10 days, the larvae emerge from the fertilized eggs. Then, these larvae feed on their food source, the mulberry leaf for about 4-6 weeks and start forming silk threads around themselves. After taking 3-8 days, the silk threads were large enough to cover their entire body. Ultimately, the larvae stay in the cocoons for 16 days until they turn into adult moths. Subsequently, after the female moth lays eggs, the life cycles begins again.
When producing silk cloth, the suitable cocoons are selected as the first step. Next, these cocoons are boiled in the water, after which the threads are unwound into strands of the length of 300-900 m. Then, these strains are twisted into thicker threads. Some of the threads are put into the dye directly, whilst some are woven to form a silk cloth, then dipped in the dye.
