Various stages involved in the life cycle of silk worm and the processes involved in the production of silk cloth are portrayed in the given diagram.
As per the first diagram, the adult moth lays eggs on the surface of mulberry leaves.The eggs hatch in a period of 10 days and silk worm larvae emerge out.
They feed on the mulberry leaves and they start encapsulating themselves with the silk thread they produce. This happens in the 4 to 6 weeks after its emergence. The process completes in 3-8 days when each larva becomes a ‘cocoon’. After staying inside the cocoon for about 16 days the larva breaks the cocoon and comes out as a moth which can fly and the cycle continues.
Turning to the second diagram, good quality cocoons are selected and boiled in water for a specific span of time. The post-boiled cocoons are unwound for the isolation of individual threads, which are 300-900 meters long. These are then either twisted and dyed or woven and dyed.
Overall, its is clear that the life cycle of the silk worm is unique and the process of silk cloth production is less complex.
