Silk
Silk is a natural protein fiber produced by silkworms. It is the only natural fiber that comes in a continuous filament, which gives it its characteristic smooth surface and natural sheen.
Where it comes from
Silk production originated in China, where it has been practiced for over 5,000 years. China, India, and Brazil are the leading producers today.
Properties
