Answer:
Discovery of silk was done in China
the rearing of silk is called sericulture
Explanation:
steps in production of silk
hundreds of eggs are laid by a female silk moth are collected on strips of cloth or paper they are kept under suitable conditions of temperature and humidity to help them hatch
the silkworm that had from the eggs are placed in clean bamboo trays that are lined with fresh mulberry leaves
the silkworms are fed mulberry leaves for about 25 to 30 days newspaper are spread over that raise to absorb excess moisture from the leaves that are cleaned regularly every few days the silkworm grow and moult 4 times
when Nature the silkworm stop eating and begin to spin cocoons they are shifted to bamboo trees that have small chambers all silkworms spins it's cocoons in a part of frame
the spinning of cocoons takes about three to seven days silk moths develop inside the cocoons
the silkworm cocoons are sorted according to colour size shape and texture usually range from white and yellow to greyish in colour
the cocoons either exposed to steam heated in an oven or carefully boiled in water this process kills the before they can emerge from the Konkan by cutting through the fibres
sericin is a natural gum that holds the silk fibres together
cocoons are taken out of the water and silk fibres are extracted by a process called reeling
reeling involves carefully and winding the continuous strand of silk that makes the cocoon the single unbroken thread reeling is usually done in special machines
as the silk is too fine to use 3 to 10 strands from different cocoons r reeled together to produce a silk thread of suitable thickness this is called reeled silk
the silk is dyed in different colours it is then spun into yarns which can be woven into silk fabric
