| Research Abstract |
On the fabricating process of synthetic fiber, characteristic properties of fiber, strong and flexible feature, are developped with the orientation induced crystallization caused by the fiber drawing. However, the molecular orientation of high-strength fibers are almost saturated, and the attainable strength is not only decided by the molecular orientation but also influenced by the spinning conditions. By the in-situ observation of fiber structure development, in particular takaing notice of smectic mesophase which can be observed in few milliseconds after necking, we have gotten the more information about the mechanism of fiber strength development.
