Summary: | Fabrication of crimped fibers has been caught much attention recently due to
remarkable improvement surface-to-volume ratio. The precise mechanism of the
fiber crimp is, however, rare and preliminary. This paper finds that
pulsation of fibers is the key factor for fiber crimp, and its configuration
(wave formation) corresponds to its nature frequency after solidification.
Crimping performance can be improved by temperature control of the uncrimped
fibers. In the paper, polylactide/ dimethylfomamide solution is fabricated
into crimped nanofibers by the bubble electrospinning, an approximate period-
amplitude relationship of the wave formation is obtained.
