Question

what is the criterion to entitle a fibre as synthetic​

Answer 1

Answer:

Synthetic fiber or synthetic fibre are fibers made by humans through chemical synthesis, as opposed to natural fibers that are directly derived from living organisms. They are the result of extensive research by scientists to improve upon naturally occurring animal and plant fibers. In general, synthetic fibers are created by extruding fiber-forming materials through spinnerets, forming a fiber. These are called synthetic or artificial fibers.
