Silk :  Silk is classified as a natural protein filament fiber and is a supposed to be discovered in 2640BC by a Chinese Princess. Today China is the leading silk producer of the world . Other major silk producing countries include Japan, India and Italy.
Flax:. Specimens of lax have been found in the prehistoric lake dwellings of Switzerland and in the tombs of Ancient Egypt . Linen mummy-cloths have been identified as more than 4500 years old.
Jute: Demand for jute goods reached a peak between two world wars, but since then the industry has experienced strong competition from bulk handling paper sacks and more recently synthetic fiber like polypropylene and polyethylene.
