How Silk is Made | Making of Silk thread from silkworm cocoons

Have you ever imagines How silk is Made? This video shows the steps of Making of Silk thread from silkworm cocoons and production of raw silk filaments and skeins.
Silk production totally depends on the tiny creature known as the silkworm, which is the caterpillar of the silk moth Bombyx mori. It feeds solely on the leaves of mulberry trees.
Only the healthiest moths are used for breeding. Their eggs are categorized, graded, and meticulously tested for infection. Unhealthy eggs are burned. The healthiest eggs may be placed in cold storage until they are ready to be hatched.
Once the eggs are incubated, they usually hatch within seven days. They emerge at a mere one-eighth of an inch (3.2 mm) long and must be maintained in a carefully controlled environment. Under normal conditions, the eggs would hatch once a year in the spring when mulberry trees begin to leaf. The silkworms feed only the leaves of the mulberry tree. The mulberry leaves are finely chopped and fed to the voracious silkworms every few hours for 20 to 35 days.
During this period the worms increase in size to about 3.5 inches (8.9 cm). They also shed their skin, or molt, four times and change color from gray to a translucent pinkish color. When the silkworm starts to fidget and toss its head back and forth, it is preparing to spin its cocoon.
As the worm twists its head, it spins a double strand of fiber in a figure-eight pattern and constructs a symmetrical wall around itself. The fibroin is held together by sericin, a soluble gum secreted by the worm, which hardens as soon as it is exposed to air. The result is the raw silk fiber, called the bave.
The life of the worm is ended by the process of 'stoving' or 'stifling' in which the cocoons are heated. Some of the cocoons are preserved so that the pupa or chrysalis inside them develop into moths for further breeding. The filature is in the factory in which the cocoons are processed into silk thread.
In the filature the cocoons are sorted on the bases of their color and size, so that the finished product can be of uniform quality. The cocoons must then be soaked in hot water to loosen the sericin. The silk is about 20% sericin, only 1% is removed at this stage. This way the gum facilitates the following stage in which the filaments are combined to form silk thread, or yarn.
Reeling may be achieved manually or automatically. The cocoon is brushed to locate the end of the fiber. It is threaded through a porcelain eyelet, and the fiber is reeled onto a wheel. Meanwhile, diligent operators check for flaws in the filaments as they are being reeled.
As each filament is nearly finished being reeled, a new fiber is twisted onto it, thereby forming one long, continuous thread. Sericin contributes to the adhesion of the fibers to each other. The raw silk filaments, are reeled into skeins. These skeins are packaged into bundles.

ok thanks now I forever know that silkworms literally get cooked alive to make silk. :'>

Yes. Same like you boil the carrot alive. Do you know plants cry, but we can't hear their frequency? Imagine if you could hear it. Everytime you open the fridge it will sound like a massacre

[@twilightanndanaez]

Just so people know, the silk worm is so domesticated that after it hatches from the cocoon, it doesnt have a mouth so it cant feed itself and their wings are incapable of flying. They die about 3 days after mating and laying eggs

[@D4NGOS]

so domesticated? that's not the case. other moths are not domesticated and still have that. that's just typical of any silk moth. it has nothing to do with silk farms

[@marysolmejia386]

steambunie only males, also its their nature and they should live those 3 days. Humans don't do anything but procreate and torture animals, then why dont WE get boiled alive

So you want to say after they get out of cocoon they mate but almost 99% are killed from dipping them in boil water for silk so when will they mate the question

True fact that it is killed when it is in its cocon stage

All the more reason not to wear silk or leather like the Jain faith teaches us, and live on cotton clothes in summer, and wool in winter or the synthetic polyester provided we recycle the polyester.

Is there anyway to get the silk out without killing the worm I guess no unless you don't boil the cocoon or steam it you can't get the silky texture or get out the head of the tread if you cut the cocoon to get the worm out before you boil you will destroy the cocoon to get the silk trade in one piece so there is no way guys

[@manichairdo9265]

Yes. Google it.

[@Ummidetohai]

Yes wait for them to hatch out of cocoon and when they come out use that cocoon.

The only difference is the time these moths die, normally they hatch, mate, lay eggs and the die. These insects are killed at a point where they have essentially lived their life, it’s not like they are killed at only a quarter of their life
