Answer 2

Answer is Silk.

It is a natural protein fibre, which can be woven into textiles.

The protein fibre of silk is composed mainly of fibroin and is produced from the larva of a certain type of insects to form cocoons.

The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori during its captivity.

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 multiple colour effects.
