Natural fiber - Wikipedia
Natural fibers or natural fibres (see spelling differences) are fibers that are produced by plants, animals, and geological processes. They can be used as a component of composite materials, where the orientation of fibers impacts the properties. Natural fibers can also be matted into sheets to make paper or felt.. The earliest evidence of humans using fibers is the discovery of wool and dyed ...
