Silk
Silk is a strong, natural protein fiber produced by insects to form cocoons, most commonly from the mulberry silkworm. It is prized for its softness, sheen, and durability, and can be woven into a luxurious fabric used for clothing, bedding, and other textiles. The cultivation of silkworms is called sericulture, a practice that originated in ancient China and has been a major trade item for thousands of years, as evidenced by the Silk Road.
