from silkmoth.​

Answer 1

Answer:

The biological scientific name of the silkworm is Bombyx Mori (In Latin mulberry Silkmoth). Silk is produced by this insect. Do you know that silk is one of the world's first products to get the 'Made in China' tag? Silk has been cultivated in China since ancient times and has been trading worldwide since then.

Silk is a natural protein fiber produced by the larvae of certain specific insects like caterpillars of moths. It is mainly composed of fibroin. There are 4 natural silk varieties, namely Mulberry silk, Tasar silk, Muga silk, and Eri silk. Let's study about silkworm through this article, and how this worm makes silk.

Do you know that the silkworm survives only for two or three days and the most unique thing is that at the same time, after every sexual contact, female silkworm insulates 300-400 eggs on the leaves of the mulberry tree? In a span of 10 days, each and every egg produces a small female insect called larvae also known as Caterpillar. Then in approximately 30 to 40 days, growth takes place, larvae become long, sloppy and magnified.

Now continuously for three days this insect spins his head around it and forms the solution of a single long thread which is known as Koya or cocoon or a cocoon is a protective case or shell that the silkworm spins around it. As soon as it comes in contact with the air, this thread solidifies and a silk thread which is about 1000 meters long is formed. Now, these larvae are converted into a pupa.

Step 1: Raising silkworms & harvesting cocoons.

Step 2: Thread extraction:

Step 3: Dyeing.

Step 4: Spinning.

Step 5: Weaving.
