答案
There are two diagrams which illustrate the life cycle of a silkworm and demonstrate how cocoons can be made into silk cloth.
The first diagram vividly reveals the basic four stages of the life of a silkworm. First of all, eggs are laid by moths, and after ten days each egg grows up into a silkworm larva that feeds on mulberry leaves. This stage lasts for up to six weeks until the larva starts to weave (spin) a cocoon of silk thread around itself. After a period of about three weeks, the fully-developed moths eventually break out of the cocoon, which also means the beginning of a new life cycle.
Cocoons are the raw material for the production of silk cloth. However, not all cocoons are qualified to make silk cloth, so they are selected first. Then, these cocoons are boiled in water in order to be able to be unwound in the following stage. After this, the threads, which are 300 to 900 metres long, are twisted together. Finally, the twisted threads are woven before being dyed or dyed directly.
Overall, the two diagrams present the life journey of a silkworm and the procedures of making silk cloth.
