Synthetic fibers can often be produced very cheaply and in large amounts compared to natural fibers, but for clothing natural fibers can give some benefits, such as comfort, over their synthetic counterparts. Natural fibers develop or occur in the fiber shape, and include those produced by plants, animals, and geological processes. Wood fiber, distinguished from vegetable fiber, is from tree sources. Animal fibers consist largely of particular proteins. Mineral fibers include the asbestos group.

Asbestos is the only naturally occurring long mineral fiber. Biological fibers, also known as fibrous proteins or protein filaments, consist largely of biologically relevant and biologically very important proteins, in which mutations or other genetic defects can lead to severe diseases. Artificial or chemical fibers are fibers whose chemical composition, structure, and properties are significantly modified during the manufacturing process. In fashion, a fiber is a long and thin strand or thread of material that can be knit or woven into a fabric. Cellulose fibers are a subset of artificial fibers, regenerated from natural cellulose.
