Silk was spun in ancient China from silkworms (bombyx mori) as early as 5000 BC. Over the period from 2700 BC to 1600 BC, domestication techniques enabled extensive production of silk thread and cloth. Although these techniques were strictly controlled by imperial decree, eventually silkworms were smuggled out to establish sericulture in Korea, Japan, and India.

It seems to be first “produced” in China around 3000 BC
