Synthetic artificial fibre instead is a fibre with a natural vegetable base, or derived from animal proteins, therefore similar to natural fibres. It is subjected to a chemical treatment through acids which decompose its natural structure, making it a colloidal solution suited for extrusion. The result is a fibrous filament that can be spun. Yarn and fabrics deriving from this process are very similar to the ones made with natural fibre, since they share similar features, with an improvement of resistance in some cases. Viscose, Acetate, Modal, PLA, Cupro and Lanital are some fibres obtained from organic chemical synthesis.
