cycle of Silkworm and manufacturing process of Silk cloth. Ielts Writing Task I
Silkworm lays eggs on mulberry
leaves which after 10 days hatch into larvae. The larvae continuously feeds on mulberry
leaves for 4 to 6 weeks and gains enormous size and finally weaves a cocoon with
help of its saliva or silk around its body. this process takes between 3 to 8
days.
If the shell is not retrieved for
extraction of silk larvae transforms itself into silkworm moth itself in matter
of 16 days.
The retrieved cocoon is boiled in
water in order to kill the larvae inside. After boiling process, shell is unwound into yarn. A cocoon can yield a
single strand of length between 300 to 900 meters. The yarn Is twisted into a thread which is
either dyed directly of woven into a cloth and sent for dye.
The lifecycle of silk worm continues
uninterrupted, if the cocoon is selected
and extracted for production of silk cloth
