  • Determination of the orientation of crystllites in PET fibres
    Sfiligoj-Smole, Majda ; Zipper, Peter
    The supercritical CO2 fluid as an alternative dyeing medium changes the fibre structure to a certain extent in dependence on the treatment temperature and pressure used. Therefore the changes of ... crystalline orientation in poly(ethylene terephtalate) (PET) fibres as brought about under the influence of supercritical CO2 were investigated. The determination of of crystalline orientation in PET is complicated by the absence of a truly meridional reflection (001). Two methods are available for the determination of Herman`s orientation factor ▫$f_c$▫: the method of Wilchinsky and the method of Dumbelton and Bowles, i.e. the method of azimuthal breadth. The differences between the results obtained in our research as a result of different measurement techniques are not significant.
