Sažetak
Electrospinning is a very simple and versitile nanofibrous production technique, very much utilized in the past decades. The current study concerns this process by presenting the production of polyurethane nonwoven fibrous mats. Three types of polyurethane samples were electrospun by setting up the primary technical parameters on the basis of polymer solution jet stability vizual detection. The electrospun fibers diameter, being the key factor that determines the functional characteristics of an electrospun end product, was evaluated for the polyurethane nonwoven fibrous mats. It was noted that the diameter range dstribution was narrower and fibers deformations disappeared as the applied voltage was increasing and the nozzle tip to collector distance was decreasing, but the lowest value of the measured fiber diameter was in the sample with the opposite operating technical parameters. The lower volume flow rate gave more uniform structure with no bead formations.
