In ancient times, silk was a textile woven from silk (mainly mulberry silk, but also a small amount of tussah silk and cassava silk). Due to the expansion of modern textile raw materials, all textiles woven with man-made or natural filament fibers can be called silk in a broad sense. Silk woven from pure mulberry silk is also called "real silk".

Silk is a specialty of China. China ancient working people invented and mass-produced silk products, which opened the first large-scale commercial exchange between East and West in the history of the world, and was called the "Silk Road". Since the Western Han Dynasty, China's silk has been shipped abroad in large quantities and has become a world-famous product. At that time, China's road to the west was called the Silk Road by Europeans, and China was also called the "Silk Country".
