Question

how is silk extracted from the caccone for class 7 and give a short answer please​

Answer 1

Answer:

Silk is obtained from the silkworm before it matures into an adult silk moth. Furthermore, the farmer extracts silk fibre in its pupa stage.

Then, the cocoons are submerged in boiling water to soften the layers of cocoons.

The silk workers brush the cocoons to untangle the silk strands.

Subsequently, they reel the silk strands into a continuous string. Reeling in the process of exposing the cocoons to extreme heat to separate the silk fibres. These fibres are twisted to become silk yarn.

The process of extracting silk threads from the cocoon is known as the reeling of silk.

Answer 2

Silk is produced during the cocoon stage of the silkworm's life cycle.

Explanation:

• A single strand of thin silk thread forms the cocoon. The cocoon must be retrieved and the threads must be taken out in order to obtain the silk.
• This is accomplished by immersing the cocoons in boiling water or dry baking them, causing the pupa to die rather than emerge from the cocoon. Boiling the cocoon also makes the silk less fragile.
• This aids in the removal of the silk fibres' threads. Silk reeling is the term for this process.
• The fibres are pulled into yarns and fashioned into fabrics after they have been reeled.
