There are two classifications of yarns that will be produced by spinning which are Filament and Staple yarns.

Filament

These yarns are made from long, and continuous strands of fiber. Most of them from synthetic and only silk represents for natural fibers in filament

Staple

Staple or spun yarns in other hand are made from short length of fibers. It can be found from natural fibers or can be produced using synthetic as staple filament yarns. As it is short length, staple fibers need to be held together with others in order to get the long and continuous yarns.
