An electrospinning apparatus for spinning polymer fibers from a fluid delivered by a jet supply device, which apparatus comprises at least one collector of a plurality of collectors in electrical communication with an electrode of the jet supply device. Collectors are insulated from each other. At least one collector comprises a stretcher adapted to stretch polymer fibers. The stretcher is an integral part of at least one collector. A controller controls sequence and time duration at which collectors are in electrical communication with the electrode of the jet supply device creating a non-woven polymer fabric or weaving polymer fibers into a fabric. The electrospinning apparatus comprises a rotator adapted to rotate the stretcher.
