The diagrams below show the life cycle of the silkworm and the stages in the production of silk cloth. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The provided diagrams in combination illustrate how the consumer

silk

thread

can be produced starting from the Silkworm’s life cycle and the manufacturing process of

silk

cloth.

Overall

, it is evident that the silkworm is considered the only insect which is responsible for producing

silk

thread

.

To begin

,

While

the mature moth lays eggs, the eggs take around 10 days to become Silkworm larvae. It is noteworthy that the Mulberry leaf plays an essential role, as it is a nutrition factor for Silkworm larvae, when the Milbberry leaf is digested, the

Silk

thread

is excreted within 4-6 weeks. In the Fourth stage, the larva completes the

thread

in the form of a Cocoon over a period of 3-8 days.

Consequently

, it returns again to its first maturity cycle stage to become a moth.

Moreover

, as soon as the produced

Silk

thread

starts another production process to be valid for knitting, the selected cocoon is subjected to boiling in a bowl of water.

This

, in turn, serves as a crucial step to untangling

thread

through a twisting technique to reach as long as 300-900 m.,

Finally

the

silk

thread

succumbs to dying in numerous types of colours to emerge in the final consuming shape of the weaved

thread

.
