8) What is the basis to decide the type of silk obtained from silk obatained from silkworm?
Answers
Explanation:
the process of obtaining Silk from silkworm is called sericulture .the scientific name of moth is known as bombyx Mori .a female moth Lays around 500 eggs in one go and dies. those were very small in size .,this eggs hatch in special Chambers usually over maths, on Beds of chopped Mulberry leaves to get small worms .the place where the Silk moths are sold is known as green ages .we grow silkworms to get cocoons we get 5 to 6 harvest of worms in a year ,they need good hygienic conditions and proper light to grow full stop when they grow bigger in size, we transfer the worms in two big sized can farmers called cocoonage.after 30 to 35 days the Caterpillar stops eating and settles at a particular place it weaves need to hold itself full stop Caterpillar moves its mouth from side to side and secrets asubstance when it is exposed to air and heat it becomes strong this forms the Silk fibre .the net is women completely to cover the body of the caterpillar .this seems to be a closed sac this is called cocoon .after 2 to 3 days 3 weeks young March come out from the cocoons and Fly Away. so we can have to be very careful within 2 to 3 days of formation of cocoon start removing them from the tray .
Wiki the Lava inside by the process called stiffling by putting a lot of these in a steam oven for 10 to 15 minutes .the cocoons have to be stiffled to killthe larva inside as otherwise it will cut its way out after growing into mouth and spoil cocoon.we will not be able to get a continuous thread of silk form such as cocoon .thus we won't be able to obtain quality fibre for Fabric !
stiffling help us to store the cocoons for a long time
this process is usually done in a reeling centres .
