    Notes: X-ray scattering from a series of poly(ethylene terephthalate) (PET) fibers spun at differet speeds is analyzed to probe the morphology in the direction transverse to the fiber axis. Both the apparent crystal modulus, determined from the change in wide-angle X-ray scattering angle with fiber stretching, and the transverse degree of crystallinity indicate there is a substantial interfiberillar amorphous content. In the PET fiber spun at conventional speeds, only roughly one-quarter of the fiber cross-section is actually occupied by fibrils. The transverse crystallinity increases for fibers spun at speeds sufficient to cause crystallization in the spin line. The X-ray moduli and fibril diameters are correspondingly larger in these high speed spun fibers. © 1993 John Wiley & Sons, Inc.

    The amorphous phase in high-speed spun PET fibers (1993)
    Bognor Regis [u.a.] : Wiley-Blackwell
    Journal of Polymer Science Part B: Polymer Physics 31 (1993), S. 1339-1345

    Notes: Two phenomenogical descriptions of oriented semicrystalline polymers, the series-parallel model and the series-aggregate model, were applied to poly(ethylene terephthalate) (PET) fibers obtained at different spinning speeds. The mechanical behavior of the fibers conformed well to both models. The analyses indicate that PET fibers obtained by high-speed spinning possess a more compliant interfibrillar amorphous phase. This feature may account for both the greater dimensional stability, as well as the more reversible mechanical behavior, exhibited by high-speed spun PET. © 1993 John Wiley & Sons, Inc.
