Question

how are Silk fibres obtained from cocoon long answers 6,7 line

Answer 1

Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons.The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors.

Larvae hatching out of eggs are released on mulberry plants .
Larvae are nourished by feeding on mulberry leaves for 3-4days , larvae moves at the branches of mulberry plants..
The silk thread is formed from secretion of their salivary glands .
Larvae spin this thread around themselves to form a cacoon .
Ten days before the pupa turns into adult , all cocoons are transferred into boiling water , the pupa dies in the cacoon and silk fibres become loose ...
This is how silk is formed from cacoons
