Abstract The crystal structure of nylon 56 fibers post extended by drawing process
was investigated by synchrotron x-ray scattering measurement. In as-cast fiber, distinct
(004) and (020) diffraction peaks were observed and they were related to initial metastable
alignment of nylon molecules. With increase in the drawing ratio, (110) peak intensity
was increased in vertical direction with decreasing (020) peak. At the same time,
(004)’ peak evolved position tilted to 29 degrees from the (004) peak. This evolution is
directly related to stable crystalline phase of nylon 56 originated from additional formation
of hydrogen bondings between N-H and C=O by post drawing process. We also compared
density variation, stress-strain curves of the fiber as a function of drawing ratio and strain.
The variations of density and tanacity also supported the increase of stable structure of
nylon 56. |
