To kill the larvae that are inside and which would otherwise bite their way out.
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
It's boiled and then unwound into a long thread.
silkworms are first boiled in water so their cocoons can die. then the silk is obtained by spreading
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

Silkworm cocoons are placed in boiling water to make the one long continuous thread separate from it.

Cocoons do not eat anything.
No More Cocoons was created in 1987.
To turn silk cocoons into carrier rods, first, the cocoons are boiled to soften the sericin, the natural gum that holds the silk fibers together. Once softened, the fibers are carefully unwound and collected into strands. These strands are then processed and twisted together to create a strong, continuous filament, which can be shaped into carrier rods through further spinning or weaving techniques. Finally, the rods may be treated or coated for added durability and functionality.
There is no standard collective noun for cocoons. Collective nouns are an informal part of language, any noun that suits the context of the situation can function as a collective noun; for example, a cluster of cocoons, an infestation of cocoons, a tray of cocoons (used in silk making), etc.
Some caterpillars do have cocoons in groups. The group is usually a family of caterpillars that build a web like nest around there to cocoons for protection.
