Abstract: A device including one or more nozzles having a tubular fiber spinning needle and method for producing non-toxic polymer fibers and microfibrous and nanofibrous polymer materials made thereof on a small to large scale using a wide range of synthetic polymers and bio-based polymers. The device and method enable continuous in-line production of polymer fibers at a high fiber production rate energy efficiently and safely. The increased polymer fiber production rate is achieved by the at least one nozzle that enables a centrifugal force acting upon the tubular fiber spinning needle causing rotational motion of the tubular fiber spinning needle and higher polymer injection rates per nozzle.

Abstract: Disclosed is a method for producing a nanofibrous non-woven material and a nanofibrous non-woven material with cross-linked gelatin nanofibers. The method includes producing gelatin nanofibers; producing a nanofibrous material using the produced gelatin nanofibers; and treating the nanofibrous material by a crosslinking agent for forming adhesion bonds in the nanofibrous material and to obtain the nanofibrous non-woven material.
