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 ...
Fiber (also spelled fibre in British English; from Latin: fibra) [1] is a natural or artificial substance that is significantly longer than it is wide. [2] Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene.
Textile fibres or textile fibers (see spelling differences) can be created from many natural sources (animal hair or fur, cocoons as with silk worm cocoons), as well as semisynthetic methods that use naturally occurring polymers, and synthetic methods that use polymer-based materials, and even minerals such as metals to make foils and wires.
Before synthetic fibres were developed, cellulose fibres were made from natural cellulose, which comes from plants. The first artificial fibre, known as art silk from 1799 onwards, became known as viscose around 1894, and finally rayon in 1924. A similar product known as cellulose acetate was discovered in 1865. Rayon and acetate are both ...
Rayon is a classified as a semi-synthetic fiber, made with natural polymers. Monomers are the building blocks of polymers. Polymers in fibers are of two types: additive or condensation. Natural fibers, such as cotton and wool, have a condensation polymer type, whereas synthetic fibers can have either an additive or a condensation polymer type.
The chemical composition of common natural fibers are shown below; [6] these vary depending on whether the fiber is a bast fiber (obtained from the bark), a core fiber (obtained from the wood), or a leaf fiber (obtained from the leaves).

Interior carpeting of a car's door made by a biocomposite of hemp fibres and polyethylene. A biocomposite is a composite material formed by a matrix and a reinforcement of natural fibers. Environmental concern and cost of synthetic fibres have led the foundation of using natural fibre as reinforcement in polymeric composites.
