What is the process for making silk fabric?
first you raise silk "worms" they are really caterpillars and turn into moths. Then you kill them all by boiling the cocoons which they weave. The substance the cocoons are made of is raw silk which is later cleaned and woven into threads in a similar way cotton is.
What grows in cocoons?
catapillers that turn into moths. A common misconception is that butterflies come from cocoons. They do not. Butterfly caterpillars shed their skin to become a chrysalis, which then sheds its exoskeleton to become a butterfly. The wrapping is silk around the caterpillar as a protective cocoon never occurs in butterfly larvae.

How long does it take a caterpillar to turn into a butterfly?
our caterpillars that we got from Bugville made their cocoons 7 days after we received them, and turned into butterflys 12 days after they made the cocoons.
What was Silk used for in ancient china?
Silk making begins with the adult silk moth, which is raised solely for reproduction. Batches of moths are kept in special houses where temperature, light and air are controlled by brazier, air vents, and blinds. This is to control reproduction so that the moths in each batch will mate at the same time. Since the moths' lives are controlled so they will mate at the same time, the eggs also are produced and hatch at roughly the same time. Once the silkworms hatch from their eggs, they are kept on bamboo trays and fed fresh mulberry leaves to store fat while they mature. As the silkworms mature, they spin cocoons from a jellylike substance in their silk glands. After about a week, some cocoons are steamed or baked to kill the worms inside. Some of the cocoons are left to nurture and release moths to reproduce. The cocoons are then plunged into boiling water to unravel the silky fibers. each cocoon consists of a thread about half a mile long. Once the cocoon fibers are unraveled, several are reeled together on a spool to make a thread strong enough for spinning. The fine silk fibers are woven into different types of cloth, from filmy gauze to heavy brocades.

What is meant by the term rearing of silk worms?
Cultivation of silkworms for the purpose of harvesting the silk from their cocoons. Silkworms eggs take about ten days to hatch. They eat continuously. They have a preference for White Mulberry having an attraction to the mulberry oderant cis-jasmone. After they have molted four times (i.e., in the fifth instar), their bodies turn slightly yellow and their skin becomes tighter. The larvae enclose themselves in a Cocoon of raw silk produced in the salivary glands that provides protection during the vulnerable, almost motionless pupal state. The cocoon is made of a thread of raw silk from 300 to about 900 meters (1,000 to 3,000 feet) long. The fibers are very fine and lustrous, about 10 micrometers (1/2,500th of an inch) in diameter. About 2,000 to 3,000 cocoons are required to make a pound of silk.
Is silk green?
Nope. Silk is white. If you dye into green, it will turn in to green.
What is the difference between a moth and a silk moth?
"Silk moth" can either refer to Bombyx mori, the species used in the commercial production of silk, or any moth in the family Saturniidae (giant silk moths). Both of these are types of moths. Bombyx mori is a medium-sized white moth with large feathery antennae that was native to China and east Asia. Saturniidae, commonly called "giant silk moths" are a very diverse group of moths found throughout the world. They tend to be large moths with gaudy colors whose caterpillars spin thick silken cocoons. The silk of Saturniidae has not been successfully used for commercial purposes.
