Silk is a natural protein fiber. Silk fabric was first developed in Ancient China, and they developed the ability to use silk. Some of the earliest examples were found in 3500 BC.

Japan has developed technology for producing a synthetic spider silk with the same qualities as natural spider silk. Not all synthetic silk has the same qualities as the natural silk though.
silk was not invented, it is a natural fibre from the cocoon of a Silk Worm. Your question should ask when silk was developed. Earliest examples found in China are from the period 3500BC
China developed silk from silkworms, and this process is still used today.

A silkworm is the larva of the silk moth, Bombyx mori. It is a domesticated insect known for its ability to produce silk.
It comes from the cocoon of the silk worm and requires a great deal of handling and processing, which makes it one of the most expensive fibers also. Today China is the leading silk producer of the world. Other major silk producing countries include Japan, India and Italy.Major use of silk is in textile industry like in clothing, house hold accessories like bed sheets cushions, curtains etc.The development of technology to dissolve silk fibers and make film from silk protein has opened the way for research and development into its use in artificial skin, blood vessels, and tendons; contact lenses; catheters for surgical procedures; and anticoagulants. All these applications exploit silk's bio compatibility and permeability.Other uses are constantly being developed, such as in membranes and filter material, which draw on silk's ability to absorb or filter out specific substances (e.g., oxygen and carbon dioxide), and in bio sensors using silk enzyme-fixing membranes that trap enzymes.Environment-friendly fishing lines are also being developed from silk. Silk is a natural material and is highly biodegradable, so it promises to play a role in solving the problem of fishing lines polluting waterfowl habitats.
