Abstract
An isothermal crystallization behavior is observed for poly(propylene) (PP) on the surface of poly(ethylene terephthalate) (PET) fibers. The extensive nucleation on the fiber surface is followed by the development of a transcrystalline phase, while normal PP spherulites appear much later than the transcrystalline phase in regions far from the interface. The crystallization kinetics is followed by spot-intensity measurements at selected areas on the picture frame near the fibers, showing that the kinetics in the transcrystalline zone is quite different from that in the PP bulk. Furthermore, a preferential orientation of the b-axis and/or bc-planes of PP crystallites along the c-axis of PET fibers is found, suggesting that the crystal structure of the fiber material could also influence the development of this phase. © Wiley-VCH Verlag GmbH, 2001.
