Animal fibers are natural fibers that consist largely of certain proteins. Examples include silk, hair/fur (including wool) and feathers.The animal fibers used most commonly both in the manufacturing world as well as by the hand spinners are wool from domestic sheep and silk.
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.
Some animals, particularly ruminants and termites, can digest cellulose with the help of symbiotic micro-organisms that live in their guts, such as Trichonympha. In human nutrition , cellulose is a non-digestible constituent of insoluble dietary fiber , acting as a hydrophilic bulking agent for feces and potentially aiding in defecation .
Natural cellulose fibers are still recognizable as being from a part of the original plant because they are only processed as much as needed to clean the fibers for use. [citation needed] For example, cotton fibers look like the soft fluffy cotton balls that they come from. Linen fibers look like the strong fibrous strands of the flax plant.

Silk fibroin has been additionally found to support stem cell proliferation in vitro. Gelatin: Gelatin is obtained from type I collagen consisting of cysteine, and produced by the partial hydrolysis of collagen from bones, tissues and skin of animals. [6]
