Abstract |
We investigated the evolution of crystal formation as a function of drawing ratio
in poly(1,4-diaminobutane-co-adipic acid-co-¥å-caprolactam-co-diethylenetriamine)(nylon
466T) copolymer formed by four monomers, i.e 1,4-diaminobutane, adipic acid, ¥å-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¥á
and unoriented nylon 46¥áphases. As increase the drawing ratio, unoriented nylon 6¥á
was transformed to oriented ¥ã phase, while unoriented nylon 46¥áchanged to oriented
46 ¥á 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. |
