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.

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.
Why silk obtained by mulberry silk moth most popular?
The Bombyx mori silkmoth's cocoon is the most predictably produced source of silk fibre as a standard. Its size, quality, and tensel strength is predictable given the complete domestsication of this animal.Economically, then, this animal's cocoon is the most popular source of commercial silk.

The production of silk?
Silk is spun from the fibres of the cocoon of the mulberry silkworm, the caterpillar of a type of moth. There are other species of bug which produce workable silk, but aren't generally used for textiles, though research continues.

Is silk is a polymer?
Silk is natural, not a man-made polymer. The silk is mainly obtained from the cocoons of the Mulberry Silkworm (Bombyx mori). When the caterpillar forms a pupae, it encases itself in a cocoon of fine silk thread. Before the adult moth emerges, the cocoon is steeped in hot water to kill the developing moth inside. The cocoon is then unravelled and is combined with several other silk threads to produce a strong silk thread that can be used to produce silk fabric.
Is silk made from a plant or an animal?
Silk is spun for the cocoon of the silkworm, an insect, before it can turn into a moth. It's vaguely similar to spider web. The silkworm is fed on mulberry leaves.
