| 摘要: |
Polyacrylonitrile triangular fiber was
prepared by the technique of dry-jet wet spinning.
In order to study the effect of air gap on the morphology
of triangular nascent fiber, various air gap
distances ranging from 3 to 7 mm were studied.
The cross-section of triangular nascent fiber was
observed through an optical microscope, the surface
of the fiber was examined with an atomic
force microscopy, and its pore structure by mercury
porosimetry. The results showed that the
profile degree decreased with the increase of air
gap distance; the surface tension was a key factor
that affected the deformation of the cross-sectional
shape of triangular nascent fiber. In addition,
surface roughness of triangular nascent fiber,
with the growth of air gap distances, increased
first and then decreased. An abrupt change of the
surface roughness of the fiber may have resulted
from that of polymer contents on the surface of
the dope stream in the air gap. Furthermore, the
pore volume in the triangular nascent fiber
decreased with the increase of air gap distance.
This may be attributed to change of the total polymer
content of the dope stream in air gap. |
