How is silk obtained from silk worms??
Answers
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:
Step I: The first step towards obtaining silk is rearing of silkworms done when mulberry trees bear a fresh crop of leaves.
The hundreds of eggs laid by female silk moth are stored carefully on strips of cloth or paper and are then sold to silkworm farmers where the eggs
are kept under hygienic and suitable conditions of temperature and humidity for their proper growth.
They are then warmed to a suitable temperature. This enables the larvae to hatch from eggs. The larvae also known as caterpillar or silkworms are
kept in bamboo trays and are served with freshly chopped mulberry leaves. They eat day and night and increase a lot in size.
After 25 to 30 days, the silkworms stop eating and move to a tiny chamber of bamboo in the tray having small racks or twigs to spin cocoons. The
silkworm spins the cocoon inside which further development into the silk moth takes place.
Step II: The second step towards obtaining silk is the processing of silk. The pile of cocoons used to obtain silk fibres are kept under the sun or boiled
or else exposed to steam to separate the silk fibres. This process is known as reeling the silk and is done using machines which unwinds the threads or
fibres of silk from the cocoon which are then spun into silk threads, and are woven into silk cloth by weavers.
