Abstract
The present invention refers to an apparatus and method for producing non-woven nanofibers from polymers. The method for producing non-woven micro nanofibers from polymers comprises the use of electrospinning and melt blowing elements. The apparatus presented for producing non-woven micro and/or nanofibers from polymers comprises a source of compressed gas, a pressure gauge, a hypodermic syringe with a pump for controlling the injection rate of the polymeric solutions, a pulverizing apparatus and a collector preferably with controlled rotation speed. The technology presented for producing non-woven micro and/or nanofibers is capable of producing micro and nanofibers having diameters similar to those produced by electrospinning, also on an industrial scale. The invention also comprises the use of non-woven nanofibers in pulverizing live tissues and as coating for materials.
