Yes it is! Silk from silkworm cocoons is extracted to be used for manufacturing of many types of clothing; meaning, that the silky clothings you are wearing are actually made of many threads of silk that were extracted from many silkworm cocoons. In fact, only one silkworm cocoon contains a single continuous silk thread that can reach about 3600 feet in length!
This method of manufacturing originated in China, where the first silk keel was invented and there are different farming methods in different countries.
The process of extraction in Chinese farms involves heating the cocoons in an oven in order to kill the silkworm inside the cocoon, and then soaking the cocoons in water in order to identify the end of the silk thread. Once theyre soaked, the silk is extracted from the cocoons using multiple threads from several cocoons to form a single silk thread (since one thread of silk from one cocoon is too thin).
Hope that helps:)

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 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.
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.
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.
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 happens to silkworms cocoon at a silk factory?
It's boiled and then unwound into a long thread.
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 is silk?
Silk comes from the silk worm's cocoon. The silkworms are fed mulberry leaves and cared for until they go into their cocoon. Then they are put in hot and cold water and the cocoon is unraveled. Then it is packed in small bundles. Then, you finally have your silk! :) it was discovered in china about 4 thousand years ago
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 silkworms spin cocoons?
they secreet it to build the coccon which we collect and weave into silk
Do silkworms produce silk?
yes they produce this cocoon and when they come out of it you can pick it and turn into silk. the Queen's wedding dress was made with English silk from an English silkworm factory.
What are the steps in making silk?
first the silkworms are fed on the leaves of the mulberry bush. then each silkworm spins a continuous thread up to 800 metres long to form a cocoon. then the silkworms are boiled in water and silk is obtained from them
