Answer:
The process of silk production is known as sericulture. ... Extracting raw silk starts by cultivating the silkworms on mulberry leaves. Once the worms start pupating in their cocoons, these are dissolved in boiling water in order for individual long fibres to be extracted and fed into the spinning reel.

Answer:
1. Cocoons are collected and kept under the sun, or boiled, or exposed to steam. This helps in separating out the silk fibers. The process by which silk thread is separated from the cocoon is called reeling the silk.
2. Then, the spinning of silk fibers into threads is done.
3. The silk threads obtained are woven into the desired clothes.
