Explanation:
Silk is a natural fibre obtained from silkworm.
It is obtained from it when it is in its pupa stage.
The rearing of silk worm for gaining silk is called sericulture. As these small creatures spin their cocoon around them, they are put in hot water to release the thread from them. In this process the silkworm dies and with its death silk thread is obtained. For making a silk tie if can take the life of about 10000 silkworms and thus the clothes of silk are very costly than any other natural fibres.
