Direct formation of "artificial wool" nanofiber via two-spinneret electrospinning
To reproduce the excellent characteristics of natural fibers like wool and proteins, a novel two-spinneret electrospinning technology was demonstrated in this communication, which can generate three-dimensional self-crimp fibers of HSPET/PTT, HSPET/PAN and PU/PAN directly. In the apparatus, two spinnerets were used to prevent gel formation or precipitation of the polymer, and the voltages of opposite polarities were applied to the spinnerets respectively. And the elecctrospun fibers morphology was observed by using scanning electron microscopy (SEM). (c) 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
