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. » Write at least 150 words.

The diagrams illustrate the life cycle of the

silkworm

and

also

the stages involved in producing

silk

cloth

. First of all, the

silkworm

life cycle begins with eggs laid by the moth, which hatch into larvae in 10 days. The

silkworm

larvae

then

feed in mulberry leaves for about 4-6 weeks, before it spins cocoon by

silk

threads

around itself. The generation of

cocoons

is usually completed in 3-8 days. After a period of about 16 days, the adult moth eventually emerges from

this

cocoon and the life cycle begins again. Shifting to the second graph, the production of

silk

cloth

involves several stages.

First,

cocoons

are selected for their quality. These

cocoons

are

then

boiled in water to loosen their

silk

fibres. After boiling, the

silk

threads

, which range from 300 to 900 meters in length, are anwound from the

cocoons

. The

threads

are

then

twisted together to strengthen the

silk

yarn.

Finally

, the yarn is dyed and woven into

silk

cloth

.

Overall

, the process of producing

silk

cloth

is intricate, starting from the biological development of the

silkworm

to the mechanical and chemical processes involved in transforming

silk

threads

into finished

cloth

. Each stage is essential to ensure the quality and usability of the final

silk

product.
