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.
The cocoon that produces the live silk, specifically from the silkworm (Bombyx mori), is considered "motherless" because it is typically harvested before the moth emerges. This process prevents the moth from breaking free, which would damage the silk fibers. By keeping the cocoon intact, the silk strands can be unraveled in long, continuous lengths, resulting in higher quality silk cloth. This method is essential for maintaining the integrity and value of the silk produced.

If the moth hatches, it chews its way out of the cocoon, cutting all the silk fibers. for silk production, the caterpillar is killed before it hatches, so the silk strands can be unwound and remain whole.

Silkmoth pupae are typically killed by boiling cocoons to prevent them from emerging as moths and breaking the silk fibers. This process helps to maintain the quality, length, and strength of the silk threads for textile production. Additionally, it simplifies the extraction of silk fibers from the cocoon.
The Bombyx mori silkmoth's cocoon is the most predictably produced source of silk fibre as a standard. Its size, quality, and tensel strength is predictable given the complete domestsication of this animal.Economically, then, this animal's cocoon is the most popular source of commercial silk.
A cocoon that produces a live silk moth is the result of the silk-producing process of silkworms, specifically the larvae of the Bombyx mori moth. These cocoon structures are spun by the larvae to protect themselves during their pupal stage as they undergo metamorphosis. The silk fibers are made from proteins secreted by the silkworm, and when the adult moth emerges, it breaks free from the cocoon, allowing for the continuation of the species. In silk production, however, many cocoons are harvested before the moth emerges, as this yields the silk fibers commercially.
The silkworm in a cocoon is thrown into boiling water to kill the silkworm. The silk is then untangled and processed into a stronger silk thread. If the silkworm is allowed to mature in the cocoon, it will make a hole (damaging the silk) as it emerges from the cocoon.

The clitellum, a glandular structure found in oligochaetes like earthworms, is responsible for secreting cocoons. This structure produces a mucous substance that hardens into a protective cocoon for the developing eggs.
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.
