Silk has been made in China since 4000BC. The Indus Valley civilization in north India was also making silk by around 2500 BC. However knowledge of silk manufacturing appears to have been lost in India after the collapse of the Indus Valley culture at around 1500 BC, leaving China with a virtual monopoly in silk production for the next 2500 years.
