According to well-established Chinese legend, Empress Hsi Ling Shi, wife of Emperor Huang Ti (also called the Yellow Emperor), was the first person to accidentally discover silk as weavable fiber.

One day, when the empress was sipping tea under a mulberry tree, a cocoon fell into her cup and began to unravel. The empress became so enamored with the shimmering threads, she discovered their source, the Bombyx mori silkworm found in the white mulberry. The empress soon developed sericulture, the cultivation of silkworms, and invented the reel and loom. Thus began the history of silk.

Whether or not the legend is accurate, it is certain that the earliest surviving references to silk history and production place it in China; and that for nearly 3 millennia, the Chinese had a global monopoly on silk production.

Here is your answer...

The production of silk originates in China in the Neolithic (Yangshao culture, 4th millennium BC). Silk remained confined to China until the Silk Roadopened at some point during the later half of the first millennium BC. China maintained its virtual monopolyover silk production for another thousand years. Not confined to clothing, silk was also used for a number of other applications, including writing, and the color of silk worn was an important guide of social classduring the Tang Dynasty.
Silk cultivation spread to Japan around 300 AD, and, by 522 AD, the Byzantines managed to obtain silkworm eggs and were able to begin silkworm cultivation. The Arabs also began to manufacture silk during this same time. As a result of the spread of sericulture, Chinese silk exports became less important, although they still maintained dominance over the luxury silk market. The Crusades brought silk production to Western Europe, in particular to many Italian states, which saw an economic boom exporting silk to the rest of Europe. Changes in manufacturing techniques also began to take place during the Middle Ages, with devices such as the spinning wheel first appearing. During the 16th century France joined Italy in developing a successful silk trade, though the efforts of most other nations to develop a silk industry of their own were unsuccessful.
The Industrial Revolution changed much of Europe’s silk industry. Due to innovations on spinning cotton, cotton became much cheaper to manufacture and therefore caused more expensive silk production to become less mainstream. New weaving technologies, however, increased the efficiency of production. Among these was the Jacquard loom, developed for silk embroidery. An epidemic of several silkworm diseases caused production to fall, especially in France, where the industry never recovered. In the 20th century Japan and China regained their earlier role in silk production, and China is now once again the world’s largest producer of silk. The rise of new fabrics such as nylon reduced the prevalence of silk throughout the world, and silk is now once again a rare luxury good, much less important than in its heyday.
