Natural fibers or natural fibres (see spelling differences) are fibers that are produced by geological processes, or from the bodies of plants or animals. [1] They can be used as a component of composite materials, where the orientation of fibers impacts the properties. [2] Natural fibers can also be matted into sheets to make paper or felt. [3 ...
Natural fibers are composed by microfibrils of cellulose in a matrix of hemicellulose and lignin. This type of structure and the chemical composition of them is responsible for the mechanical properties that can be observed. Because the natural fibers make hydrogen bonds between the long chains, they have the necessary stiffness and strength.
Fiber crops are field crops grown for their fibers, which are traditionally used to make paper, cloth, or rope. [1] Philippine natural fibers. Fiber crops are characterized by having a large concentration of cellulose, which is what gives them their strength. The fibers may be chemically modified, like in viscose (used to make rayon and ...
More specifically, leaf fibers are typically found in monocotyledonous leaves. [1] The fibers are harvested from plants in long, thin bundles mainly through the process of decortication which is where the non-fibrous tissues are scraped away from the plant fibers by hand or in a machine. For the majority of cases, the leaves must be hand-picked ...
Natural and synthetic fibers used to make products such as textiles, rope, thread and paper. Natural fibers are an integral part of the cytoskeleton of cells and are also found in abundance in the extracellular matrix .
Natural fibers develop or occur in the fiber shape, and include those produced by plants, animals, and geological processes. [2] They can be classified according to their origin: Vegetable fibers are generally based on arrangements of cellulose , often with lignin : examples include cotton , hemp , jute , flax , abaca , piña , ramie , sisal ...

Dietary fiber is defined to be plant components that are not broken down by human digestive enzymes. [1] In the late 20th century, only lignin and some polysaccharides were known to satisfy this definition, but in the early 21st century, resistant starch and oligosaccharides were included as dietary fiber components.
