Catch the cocoons before the moth emerges, and soak in hot water for a time, try 30 to 60 minutes. Start pulling the 'fluff' away and you will come to one thread that starts to unravel. Put aside and do the same with your other cocoons. When you have enough threads to make a yarn of the size you want. Put all the cocoons in a bowl of water, pull the threads through the teeth of a fine comb and start winding those threads onto a cardboard 'bobbin' or old cotton real or a wool winder. Keep going until you use up all the thread. Rescue the moth chrysalis and put it in a safe dark place like a shoe box with a lid with holes in it, and allow to emerge when ready. To mate and hatch more little silk worm eggs to later give you more silk.

How is silk obtained and manufactured?
We obtain silk by killing the larvae inside by a process called stiffling by putting a lot of these in a steam even for 10 to 15 minutes. Obtaining silk fibre from cocoon is called reeling. It is done with special machines called reelers and twisters. The silk fibre is carefully collected from the cocoon and nearly 3 to 8 of such threads are wounded together to make yarn from it which is reeled. This yarn is cleaned, bleached and colored. This yarn is ready.
Why silkworms are not killed?
Silkworms are killed when the cocoon is dropped into boiling water. Once dead, the silk is carefully unwound from the cocoon. As a single silk yarn, it is very weak. By combining several single yarns together a stronger usable yarn is formed.
What are three grades of silk explain?
'''Grade 1''' is silk yarn reeled from the inner layers of the cocoon. It is even in structure, size and color, round, clean and free from adulterated materials. '''Grade 2''' is silk yarn reeled from a combination of the inner and outer layers of the cocoon. It is not even in structure, but is even in size and color, round, clean and free from adulterated materials. '''Grade 3''' is the silk yarn reeled from the outer layer of the cocoon with the addition of the floss from the innermost layer. It may contain some knots. It is round, even in size and color, clean and free from adulterated materials.
How does raw silk become yarn?
Raw silk is harvested from cocoons of silk worms. The cocoons are lowered into hot water, which terminates the worm's use of the cocoon. Then the cocoon is carefully unwound to produce strands of raw silk. Additional processing may take place, depending on the type of raw silk being produced. The worm is disposed of.
How does the invention of silk work?
Silk is not do much an invention as a discovery. ?The discovery that the cocoon of the silkworm moth lava could be boiled and unravelled as one continuous thread. This thread is then twinned with others to make a silk yarn which is woven into fabric. The secret of silk was discovered by the ancient Chinese who learned how to domesticate and farm the silk worm moths, feeding them on a type of mulberry leaf.
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. Commercial silk is strong, easily dyed and wonderfully reflective of light. So the short answer is, silk originates from a caterpillar's bottom. Did you really want to know that?
Does silk provide yarn?
Yes, sort of. Silk is a thread (which can be made into a yarn) produced by the pupating Silk Moth caterpillar.
Why are some cocoons boiled during harvesting of silk thread?
It must be kept in mind that about 1 per cent of total harvest of cocoons is not boiled. The insects within the cocoon are allowed to mature to form silk moths. These silk moths cut through the cocoons and are allowed to breed for silk worm eggs for future production of silk. The silk from the damaged cocoons is collected and mixed with the filaments of coarse outer portion of the cocoon as well as from the inner portions of cocoons which is left after reeling. This mixture is then spun to obtain low grade silk yarn..by DEEPANKAR MECH

What is dupioni silk?
Dupion silk is the silk obtained from double cocoons. The fabric made out of this silkyarn is the dupion fabric.The yarn and the fabric have more neps or slugs on it which is a natural feature.Some times defective cocoons are also mixed with the double cocoons to obtain dupion silk yarn.The dupion yarn is coarser than the reeled yarn. In most parts of Karnataka,India,the double cocoons are usually reeled on Charakha.These days they are also reeled on dupion reeling machine.
What is the importance of silkworms?
The silkworm is the larva or caterpillar of the domesticated silkmoth, Bombyx mori. At a certain stage, it weaves a cocoon of silk round itself before beginning its change into a moth. The cocoon is dunked in hot water to kill the caterpillar, and the cocoon is carefully unravelled. Several threads are combined to make the silk yarn used in some clothing.
How raw silk is produced?
The process used to make silk fabric for sheets (or anything else) is called Sericulture or silk farming AKA the rearing of silkworms for the production of silk. Silkworm larvae eat mulberry leaves until they are about 10,000 times heavier than when they first hatched and are ready to make a cocoon. The silk is produced in two glands in the silkworm's head and then forced out in liquid form through openings called spinnerets and then solidifies when coming into contact with the air. The silkworm spins about 1 mile of filament in the next two to three days to form its cocoon. The outside of the cocoon is then brushed to find the end of the silk filament, which is then wound on a reel.
