What animal makes silk?
Silk is produced by silkworms, which are the larvae of silk moths. The silkworms spin silk to create cocoons in which they undergo metamorphosis into adult moths. The silk is harvested from these cocoons and woven into fabric.
Do silk moths produce silk?
Yes. Silk fibre comes from their cocoons.
Is silk man made or natural?
natural. silk is made by silk wormsSilk is a natural fibre produced by silk worms -- moths, really -- that spin cocoons which, when unraveled upon the death of the worm, become silk strands.
How you get silk from butterfly?
Silkworms, which emerge from their cocoons as moths, spin cocoons that are the raw material for the fibre humans use as silk. Cocoons are harvested from domesticated silkworms by heating the cocoon to kill the animal, then the silk cocoon is unraveled. Once the moth has emerged -- in wild silkworms for example, the cocoon's silk can be harvested, but not in one continuous length. As a moth, there is no connection with the now-discarded cocoon.
Why is cocoons that produces a live silk moth useless?
Cocoons that produce live silk moths are considered useless for silk production because the emergence of the moths compromises the integrity of the silk thread. When the moths break free from the cocoon, they create holes and frayed ends in the silk fibers, rendering the material less valuable and unsuitable for high-quality textile production. Additionally, the process of harvesting silk typically involves killing the pupa before it emerges, ensuring the integrity of the silk strand. Thus, cocoons that yield live moths do not meet the economic demands of the silk industry.
Why are some cocoons not boil 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

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.
What is larva of silkworm?
The larva of the silkworm, known as the silkworm caterpillar (Bombyx mori), is the juvenile stage of the silk-producing moth. These larvae primarily feed on mulberry leaves and are essential for silk production, as they spin cocoons made of silk fibers during their pupation stage. Silkworm larvae are notable for their rapid growth and transformation, ultimately becoming adult moths that emerge from the cocoons. The silk harvested from these cocoons has been highly valued for centuries in textile production.
Do butterflies make coccon?
Bu6terflies make chrysalises rather than cocoons. Moths make cocoons out of silk and butterflies make chrysalises during their molting.
What is the process for making silk fabric?
first you raise silk "worms" they are really caterpillars and turn into moths. Then you kill them all by boiling the cocoons which they weave. The substance the cocoons are made of is raw silk which is later cleaned and woven into threads in a similar way cotton is.
Do butterflies spin cocoons?
No, butterflies form chrysalids but some species spin silk onto leaves to form a hibernaculum out of the leaf.
