1. The silk moth lays thousands of eggs.
2. The silk moth eggs hatch to form larvae or caterpillars, known as silkworms.
3. The larvae feed on mulberry leaves.
4. Having grown and moulted several times silkworm weaves a net to hold itself
5. It swings its head from side to side in a figure '8' distributing the saliva that will form silk.
6. The silk solidifies when it contacts the air.
7. The silkworm spins approximately one mile of filament and completely encloses itself in a cocoon in about two or three days. The amount of usable quality silk in each cocoon is small. As a result, about 2500 silkworms are required to produce a pound of raw silk
8. The intact cocoons are boiled, killing the silkworm pupae.
9. The silk is obtained by brushing the undamaged cocoon to find the outside end of the filament.
10. The silk filaments are then wound on a reel. One cocoon contains approximately 1,000 yards of silk filament. The silk at this stage is known as raw silk. One thread comprises up to 48 individual silk filaments.

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
The process of silk production is known as sericulture. The entire production process of silk can be divided into several steps
once the silkworms form their cocoons, the intact cocoons are boiled, killing the silkworm .The silk is then obtained by brushing the undamaged cocoon to find the outside end of the filament.the filament is then pulled carefully to take out the long silk thread forming the cocoon.
hope this helped you!!
