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..

Why are cocoons boiled in hot water?
cocoons are boiled in hot water so that the gummy substance called the sericin can come out so that it is easy to pull out the thread called silk

What are the various stages involved in the sericulture?
Sericulture involves several key stages: Silkworm Rearing: This begins with the selection of high-quality silkworm eggs, which hatch into larvae that are fed mulberry leaves. Cocoon Formation: After several molts, the larvae spin cocoons using silk threads. Cocoon Harvesting: Once the cocoons are formed, they are harvested and processed. Silk Extraction: The cocoons are boiled or steamed to extract silk fibers, which are then spun into silk thread for weaving and other uses.
Why is a cocoon that produces a live silkmoth useless for making silk clothes?
The silk that is made into the cloth is the thread that the silkmoth caterpillar spins to make its cocoon. Thus the cocoons are boiled to kill the pupa and free the silk thread.
Why are silk cocoons boiled?
Silkworm cocoons are placed in boiling water to make the one long continuous thread separate from it.

What does silk farmer do with cocoons not needed for breeding purpse?
they kill the silkworm that is inside to get the cocoon into fiber (thread)
When silk obtained from silk moth?
Silk is obtained from the cocoon of the silkworm, which is the larval stage of the silk moth (Bombyx mori). After the larvae spin their cocoons, they undergo metamorphosis into moths. To harvest silk, the cocoons are typically boiled or steamed to kill the pupa and loosen the silk fibers, which are then carefully unwound and processed into silk thread. This process has been practiced for thousands of years, primarily in countries like China and India.
Is silk from the silkworms cocoon used to make anything?
Yes it is! Silk from silkworm cocoons is extracted to be used for manufacturing of many types of clothing; meaning, that the silky clothings you are wearing are actually made of many threads of silk that were extracted from many silkworm cocoons. In fact, only one silkworm cocoon contains a single continuous silk thread that can reach about 3600 feet in length! This method of manufacturing originated in China, where the first silk keel was invented and there are different farming methods in different countries. The process of extraction in Chinese farms involves heating the cocoons in an oven in order to kill the silkworm inside the cocoon, and then soaking the cocoons in water in order to identify the end of the silk thread. Once theyre soaked, the silk is extracted from the cocoons using multiple threads from several cocoons to form a single silk thread (since one thread of silk from one cocoon is too thin). Hope that helps:)
How many cocoons are needed to get 1kg of raw silk?
It takes about 2,000 to 3,000 cocoons to produce 1 kg of raw silk. Each cocoon is made up of a single continuous thread of silk spun by the silkworm larvae.
