Natural fibers represent the 40% of the fibers used in the world, while 60% are from man-made fibers.
The natural fiber cotton is the most prevalent of which are produced annually about 25 million tons. Main producing countries are China, the United States, Pakistan, India, Uzbekistan, Turkey and Brazil. Cotton is highly prevalent in Africa (Mali, Benin, Burkina Faso, Chad) and is a source of survival for entire regions. The annual production of wool is just over 2 million tons, and the areas most affected by this type of economy are Australia, China, New Zealand, Iran, Argentina and the United Kingdom. Interesting attempts to develop farms and reconstruction of a production chain of native wool products are being tested also in Italy as an attempt to enhance a material that is otherwise intended for disposal in landfills. Other fibers important for the economy of producing countries are jute (the concentrated largely in India and Bangladesh), sisal, hemp, coir, linen, silk..
