How you get silk from butterfly?
Silkworms, which emerge from their cocoons as moths, spin cocoons that are the raw material for the fibre humans use as silk. Cocoons are harvested from domesticated silkworms by heating the cocoon to kill the animal, then the silk cocoon is unraveled. Once the moth has emerged -- in wild silkworms for example, the cocoon's silk can be harvested, but not in one continuous length. As a moth, there is no connection with the now-discarded cocoon.
What happens to a silkworm after it produces silk and how have traditional silk farming methods led to the deaths of millions of silkworms?
The silkworm in a cocoon is thrown into boiling water to kill the silkworm. The silk is then untangled and processed into a stronger silk thread. If the silkworm is allowed to mature in the cocoon, it will make a hole (damaging the silk) as it emerges from the cocoon.
What is the source of silk threads?
Silkworms, a type of caterpillar, are the source of silk threads. Silkworms make a cocoon about an inch long in an oval shape. Silkworms only eat the leaves of white mulberry trees.
Why silkworms are not killed?
Silkworms are killed when the cocoon is dropped into boiling water. Once dead, the silk is carefully unwound from the cocoon. As a single silk yarn, it is very weak. By combining several single yarns together a stronger usable yarn is formed.
Where does silk come from what happens to the cocoon?

What is the importance of silkworms?
The silkworm is the larva or caterpillar of the domesticated silkmoth, Bombyx mori. At a certain stage, it weaves a cocoon of silk round itself before beginning its change into a moth. The cocoon is dunked in hot water to kill the caterpillar, and the cocoon is carefully unravelled. Several threads are combined to make the silk yarn used in some clothing.
Where silk came from?
Silk is the material produced by the silk worm to make its cocoon. The silkworm that makes the best quantity of silk is the mulberry silkworm. Shortly before the silkworm is going to eat its way through the silk of the cocoon, the worm is killed by humans so the cocoon can be unraveled into a single thread.
What are facts about silk worms?
Silkworms lay about 300 to 400 eggs at a time. The raw silk of a single cocoon contains raw silk thread of about 300 to 900 meters in length. Silkworms eat white Mulberry tree leaves.
How do they make silk at the factory?
they spin it out of a cocoon then theyweave it in to chlothes
What are the steps in making silk?
