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.
Silk is made from the cocoons of silkworms.
No. Silk fibre is spun by silkworms as cocoons.
Sericulture is the practice of rearing silkworms for the production of silk. This process involves feeding the silkworms mulberry leaves until they spin cocoons, which are then harvested and processed to extract the silk fibers. Sericulture is an important industry in many countries around the world.
less than half a year
Silk is made from the cocoons of silkworms. It takes 5500 cocoons to make just 2.2 lbs., or 1 kilogram, of silk.
They make silk...when the spin their cacoon
Silk is a natural fiber taken from the cocoons of silkworms, that feed on the leaves of mulberry trees. So as long as there are silkworms and mulberry trees, then silk is a renewable resource.
Tussore silk is the silk woven from the cocoons of wild silkworms feeding on some mountain shrub.
