Answer 1

• :What is silk?

• Silk is a natural fibre made by the silk worm cocoon. Silk fibres are very strong and are often used to make cloth. The Chinese invented silk in 3000 B.C. and traded it across the world through the Silk Road because it was very valuable and costly .

• .The cloth from silk can be made into rugs, bedding, or can be used to write or paint on. In the past, silk was used to make parachutes. The practice of growing silkworms for silk production is called sericulture.

• Most spiders make a natural fibre of their own that is also called silk.

• How is it obtained from silkmoth ?

• Silk is produced by several insects; but, generally, only the silk of moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level.[2] Silk is mainly produced by the larvae of insects undergoing complete metamorphosis, but some insects, such as webspinners and raspy crickets, produce silk throughout their lives.[3] Silk production also occurs in hymenoptera (bees, wasps, and ants), silverfish, mayflies, thrips, leafhoppers, beetles, lacewings, fleas, flies, and midges.[2] Other types of arthropods produce silk, most notably various arachnids, such as spiders.

• Write and explain the different processes involve​

• The various steps involved are: (i) Rearing of silkworms: A female silk moth lays hundreds of eggs at a time. ... (iii) Converting silk fibres into silk cloth: Silk fibres obtained from cocoons are spun (twisted) to form silk threads called silk yarn. The silk yarn is then woven on looms into silk cloth by the weavers

Answer 2

Answer:

Sericulture is the rearing, breeding and management of silkworms for the production of RAW silk. For obtaining silk , silk moths are reared and their cocoons are collected to get Silk threads. Silk yarn come from the cocoon of the Silk worms. The Caterpillar hatches from the very small egg and is an eating machine.
