Die umgekehrte Gas-Chromatographie bei konstanter Temperatur (100 °C) gestattet es, bei Polyithy- lenterephthalat tiberhalb der Tg-Temperatur zu arbeiten, so dab das gesamte polymere Material an der Diffusion der eindringenden Sonde teilnimmt. Es hat sich herausgestellt, dab sich dieses Verfahren ftir die Hervorhebung morphologischer Unterschiede zwischen den Polyesterfasern eignet. Die gaschromato- graphische und r6ntgenographische Charakterisierung von Handelsfasern und im Laboratorium behandelten Fasern ftihrt zu einer Hypothese tiber ihre strukturelle Ausbildung und deren Einwirkung auf dieF/irbbarkeit.
The inverse gas-chromatography performed in isotherm at 100 °C on polyethyleneterephthalate allows to work over the Tg-temperature and consequently the probe can penetrate into the whole polymetric material. The technique is suitable to show the morphologial differences among polyethyleneterephthalate fibers. The gaschromatographic and r~Sntgenographic characterization of commercial fibers and of fibers which have been treated in laboratory allows to put forward a hypothesis of the structural evolution and its influences on the dyeability.

Abstract

The technique is suitable to show the morphologial differences among polyethyleneterephthalate fibers. The gaschromatographic and r~Sntgenographic characterization of commercial fibers and of fibers which have been treated in laboratory allows to put forward a hypothesis of the structural evolution and its influences on the dyeability.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
