The in-situ measurements were carried out as a function of elapsed time after necking, achieving a high time resolution of 0.25 ms. The quasi-hexagonal phase appeared just after neck-drawing, and developed with increasing crystal orientation factor and decreasing long period and d-spacing within less than 1 ms after drawing. The crystallization induction time and the crystallization rate of the quasi-hexagonal phase obtained from the equatorial intensity profiles were 0.02 ms and 3.0 ms-1. The crystal orientation factor continued to increase, and saturated about 0.95 at about 8 ms after necking. And after then, the quasi-hexagonal phase started to transform into orthorhombic crystal in several decades of milliseconds with the decreasing of fiber temperature., Article, SEN-I GAKKAISHI. 70(4):76-83 (2014)}, pages = {76--83}, title = {Poly(p-phenylene sulfide)のレーザー加熱延伸工程における繊維構造形成}, volume = {70}, year = {2014} }
