The given diagram outlines the lifespan of a silkworm and the multi-stage process by which silk cloth is manufactured.
Overall, the silkworm’s life cycle is cyclical, consisting of four main stages and beginning with laying eggs before eventually returning to the initial stage. The production of silk cloth undergoes 5 stages, beginning with collecting the cocoon and the weaving of silk thread into cloth.
The life cycle of the silkworm commences with the laying of eggs by the adult moth. After 10 days, the eggs hatch into larvae. The larvae consume mulberry leaves and grow for 4-6 weeks. Following this, the larva spins a protective cocoon around itself over a period of 3-8 days. The cocoon is made from a single thread of silk. In 16 days, the silk moth appears from the cocoon , thereby restarting the life cycle.
The production of silk cloth begins with the selection of suitable cocoons. The selected cocoons are then boiled in water, after which the silk threads are unwound from them. Next, the threads are twisted together before being woven into silk cloth. The silk can be dyed at several stages of the process, either before or after the threads are woven into cloth.
