Applications
Industrial use
Of industrial value are four animal fibers: wool, silk, camel hair, and angora as well as four plant fibers: cotton, flax, hemp, and jute.  Dominant in terms of scale of production and use is cotton for textiles.Natural fiber composites
Natural fibers are also used in composite materials, much like synthetic or glass fibers. These composites, called biocomposites, are a natural fiber in a matrix of synthetic polymers. One of the first biofiber-reinforced plastics in use was a cellulose fiber in phenolics in 1908. Usage includes applications where energy absorption is important, such as insulation, noise absorbing panels, or collapsable areas in automobiles.Natural fibers can have different advantages over synthetic reinforcing fibers. Most notably they are biodegradable and renewable. Additionally, they often have low densities and lower processing costs than synthetic materials. Design issues with natural fiber-reinforced composites include poor strength (natural fibers are not as strong as glass fibers) and difficulty with actually bonding the fibers and the matrix. Hydrophobic polymer matrices offer insufficient adhesion for hydrophilic fibers.
