What are the steps required for the production of silk from silkworm?
How is silk made?
- Sericulture. This is the term used to describe the process of gathering the silkworms and harvesting the cocoon to collect the materials.
- Thread extraction.
- Dyeing.
- Spinning.
- Weaving.
- Finishing.
What is the life cycle of the silkworm?
life cycle of a silkworm can be primarily divided into 4 stages-namely the egg (ovum), larva, pupa, and adult (moth). The number of days required for each stage is 10 to 14 days for the egg, 20 to 25 days for the larva, 10 to 14 days for the pupa, 7 days for the adult and 50 to 60 days for 1 cycle ( Fig. 1).
What are the four stages of silk production?
Silkworm has four stages in its life cycle viz., egg, silkworm, pupa and moth. Man interferes this life cycle at the cocoon stage to obtain the silk, a continuous filament of commercial importance, used in weaving of the dream fabric.
What is the first step in silk production?
Ans. The first step in silk production is the cultivation of quality feed for the silkworms.
What are the steps in sericulture?
For the production of mulberry silk, the sericulture process follows three primary steps.
- Moriculture – the cultivation of mulberry leaves.
- Silkworm rearing – promoting the growth of the silkworm.
- Silk reeling – the extraction of silk filaments from the silkworm cocoons.
What is cocoon in the life cycle of silkworm Class 10?
What is cocoon? The salivary glands of larva of silkworm secretes sticky fluid which on exposure to air turns into fine long thread of silk. The silk thread becomes wrapped around the body of the pupa forming a case called a cocoon.
How is silk cloth prepared?
The process of silk production is done by cultivating the silkworms on mulberry leaves. Once the worms start pupating in their cocoons, these are dissolved in boiling water in order for individual long fibers to be extracted and fed into the spinning reel.
What are the steps of sericulture?
For the production of mulberry silk, the sericulture process follows three primary steps.
- Moriculture – the cultivation of mulberry leaves.
- Silkworm rearing – promoting the growth of the silkworm.
- Silk reeling – the extraction of silk filaments from the silkworm cocoons.
What is the final part of the silk production?
the weaving of the fabric
Ans. The final part of silk production is the weaving of the fabric which is considered more of an art than an act.
What are the methods used in silk farming?
What are the four stages of life history of silk worm?
The life cycle of a silkworm comprises 4 stages. They are eggs, caterpillars, cocoons, and adult moths. The life cycle of a silk moth starts when the female silk moth lays eggs.
What are four stages in the life history of silkworm?
The order of their life cycle is Silkmoth → egg → silkworm → pupa.
How do you start a silkworm farm?
When it comes to producing this silk, there are seven key stages to the sericulture process.
- Egg Hatching. The first stage of silk production is egg laying and hatching.
- Feeding.
- Molting.
- Spinning the Cocoon.
- Reeling the Filament.
- Degumming.
- Dyeing the silk.
How silk is obtained and cultivated?
Stages of production The female silkmoth lays 300 to 500 eggs. The silkmoth eggs hatch to form larvae or caterpillars, known as silkworms. The larvae feed on mulberry leaves. Having grown and moulted several times, the silkworm extrudes a silk fibre and forms a net to hold itself.
How is silk cloth made?
Silkworms make cocoons out of one long strand of fiber, which means that a fully unraveled cocoon results in a single string of silk. To unravel a cocoon, a silk worker or an automated machine will brush the cocoon to find the loose end and load it through a porcelain eyelet onto a reel that unravels silk strand.
Where is silk most produced?
China
Silk fiber is one of the strongest natural fibers available in filament form. China is the largest producer of silk, followed by India. Together, the two nations account for about 95% of the world’s silk production. More mulberry silk, produced by the silkworm B.
How does silkworm farming work?
Place a straw frame over each silkworm tray so that silkworms can start spinning a cocoon. Within 2–3 days, the silkworm spins about 1 mile of filament and is completely encased in a cocoon. The silk farmers then heat the cocoons to kill the silkworms.
What are the methods of silk farming?
Answer: Farming and shearing are the methods used by silk farming.
