  Silk Worm
Silk is a continuous filament fibre consisting of fibroin protein secreted from two salivary glands in the head of each larva and a gum called sericin which cements the two filaments together.
Next, the raw silk is twisted into a strand sufficiently strong for weaving or knitting.  This procedure is called throwing, and prevents the thread from splitting into its constituent fibres.  Four different types of silk thread may be produced from this procedure: crepe, tram, thrown singles and organzine.
After the silk is harvested from the cocoons it is brought to the weavers for dyeing and preparation for weaving.

  Silk
Cocoons are soaked in a basin of water at 140° F to soften the silk gum, or sericin.
Then the tiny strands of silk are reeled off, passing through glass guides on their way to the reels in the background and in the process of being twisted with from 2 to 6 other strands.
In the silk factory, the cocoons are soaked in hot water and the silk thread unwound.

From that historic moment, the Chinese discovered the life cycle of the silk worm and for the next 3000 years were to keep their monopoly of silk.
In the 3rd Century B.C., Chinese silk fabrics were beginning to find their way throughout the whole of Asia, and were transported overland to the west, and by sea to Japan, in those long itineraries known as the silk roads.
Silk is still produced in smaller quantities in many other countries, and several developing countries are studying new sericultural projects.

 Paterson, New Jersey --Reading 1
Silk is a natural fiber taken from the cocoons of the silk worm.
The process of producing silk fabrics was divided into four stages: throwing (twisting the silk fibers into threads strong enough to be used in the looms), dyeing, weaving, and finishing.
In spite of the owners' efforts to reduce silk weaving to a series of simple tasks that could be performed by unskilled workers, many operations involved a high proportion of hand work that depended on the skill of the individual worker.

Finally, the silk is loosely twisted 80 times into a loop to form a skein of silk.

 History of Sericulture, Cultural Entomology Digest 1
In 877 A.D., the rebel chief Biachu captured Canfu, the center of foreign silk trade, put to death all its inhabitants, destroyed all of the mulberry trees and silkworms of the region, and levied heavy and cruel taxes on all foreign trade.
This interest in silk culture soon led to what was known as the "Mormus multicaulis craze." Anticipating a most profitable investment, if not speedy riches, thousands of individuals purchased mulberry plants of the M. multicaulis species and planted large areas of valuable land.
The silk is a continuous-filament fiber consisting of fibroin protein secreted from two salivary glands in the head of each larvae, and a gum called sericin, which cements the two filaments together.

 Silk Production
By this time, the worm's two silk glands are fully developed, and it begins to exude silk from both at the same time, as well as a sticky substance called sericin to bind the two threads together.
The silk is liquid in the worm's body, but hardens into a thread in contact with the air as the larva moves its head in a characteristic figure eight pattern.
Next, since an individual silk thread is too fine to handle, the threads of as many as ten cocoons are wound together onto a reel, sticking together to form one long, strong thread.

As the worms busy themselves by building cocoons, the silk producer is also busy ensuring that the worms are distributed evenly on the mountage and that all excreted wasted is immediately disposed of.
