The illustration given presents the metamorphosis of a silkworm and how
silk
fabric is produced from silkworm cocoons.
The silkworm's life cycle begins when eggs are laid on mulberry leaves by an adult moth
. After that, on the tenth day, the larvas will hatch off and eat leaves as their main source of food. This
stage takes four to six weeks to occur until the larvas began to wrap themselves with silk
threads for 3-8 days. Next,
the cocoon will be fully made and a mature moth
will come out after approximately two weeks. Then
the moth
will mate and lay eggs, and the entire cycle is repeated all over again.
In producing silk
cloth, the cocoons of silkworms are selected and put into water inside a pot, where they are boiled at high temperature
. The cocoons will loosen and Fix the agreement mistake
temperatures
silk
threads can be twisted into 300-900 meter single cord. At this
time, the dyeing step can be done either when they have twisted the threads or after weaving the silk
cloth.
Overall
, the average lifespan of silkworms is 9-11 weeks and consists of five main stages, which are egg, larva, cocoon, and moth
, whereas
the manufacturing processes of silk
cloth include boiling, unwinding, twisting, and weaving.Submitted by twiggseducationbdg on
