Natural fibres
natural fibres are fibers that are produced by plants, animals, and geological processes. They can be used as a component of composite materials.
Synthetic fibres
synthetic fibres are made by humans through chemical synthesis. They are the result of extensive research by scientists to improve upon naturally occurring animal and plant fibres.
Regenerated fibres
manufacturing process used when the raw material is reformed or regenerated. Traditionally that raw material is cellulose, such as wood pulp or cotton waste and linters from cotton fabric manufacture.
