WORLD HISTORY

Detailed explanation-1: -Silk is a soft, smooth cloth that has been used by humans for thousands of years. It is made of fine threads woven by silk-moth caterpillars. These tiny creatures weave the threads into cocoons to protect themselves during metamorphosis. Human beings can harvest the cocoons and extract the threads to make silk fabric.

Detailed explanation-2: -Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons.

Detailed explanation-3: -The cocoon is a multilayer composite material formed by continuous twin silk filaments bonded by silk gum. The process of silk spinning and cocoon building has evolved over thousands of years through natural selection [10], [11].

Detailed explanation-4: -Silk processing: The cocoons are held under the sun or boiled or exposed to steam. The silk fibres separate. They obtain threads from a cocoon to use them as silk through the process is known as “reeling the silk. Reeling is done in unique apparatuses, which unwind the threads or fibres of silk from the cocoon.

Detailed explanation-5: -silkworm moth, (Bombyx mori), lepidopteran whose caterpillar has been used in silk production (sericulture) for thousands of years.
