write few sentences appreciating the hard work of people involved in the process of making silk fabric
Answers
Answer:
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.[1] The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors.
Answer:
Humans have been making silk for centuries. It's a coveted textile for gowns, sheets, and robes. But why is it so expensive? Silk is the product of the domesticated silkworm, Bombyx mori. The caterpillars eat constantly. They're fed mulberry leaves five times a day. After 45 days of munching and growing, the worms are ready to mature.
They have a special spinneret that secretes one long continuous filament. That's the silk. The silkworms spin this filament into a cocoon. Then the caterpillar begins its transformation. Except, this is when silk producers get in. The cocoons are steamed. This cleans them and kills the pupa inside. If the pupas were kept alive, they would degrade and break the silk. Then the cocoons are unraveled to reveal around half a mile of usable filament.
Filaments are joined to create a thread thick enough to weave into fabric. One yard of silk fabric costs approximately $100.
