We investigated the evolution of crystal formation as a function of drawing ratio
in poly(1,4-diaminobutane-co-adipic acid-co--caprolactam-co-diethylenetriamine)(nylon
466T) copolymer formed by four monomers, i.e 1,4-diaminobutane, adipic acid, -caprolactam,
diethylenetriamine(DETA), using synchrotron X-ray scattering measurement. In
case of pristine(as spun) nylon 466T fiber, it was consisted with unoriented nylon 6
and unoriented nylon 46phases. As increase the drawing ratio, unoriented nylon 6
was transformed to oriented phase, while unoriented nylon 46changed to oriented
46 phase. The effect of the addition of DETA was not observed in the pristine fibers.
However, DETA affected to restrict the formation of crystals at the maximum drawing
condition, and as a result it had a role to increase the moisture regain. |
