A new route consisting of simultaneous centrifugal spinning and solution blowing to form polymer nanofibers is reported. The fiber diameter (60-1000 nm) is shown to be a function of polymer concentration, rotational speed, and working pressure of the processing system. The fiber length is dependent on the rotational speed. The process can deliver 6 kg of fiber per hour and therefore offers mass...

Amacroscopic model for the description of lowand high-speed fiber spinning of crystallizing polymers is proposed. The model incorporates air drag, air cooling, gravity, surface tension and the viscoelastic rheological behavior of the melt. The crystallization dynamics are formulated through a set of rate equations, which describe the quiescent nucleation and growth of spherulites, as well as th...
