Poly(ethylene terephthalate) monofilaments spun at speeds ranging from 4 to 9 km/min were studied using a flexible thermomechanical analyzer, Instron tensile tester, transmission electron microscopy, and differential scanning calorimetry. Dynamic shrinkage tension behavior, modulus and elongation, electron diffraction patterns of ultra thin cross sections of fibers, and the melting behavior of the materials are discussed in terms of structural stability, crystallinity, and crystalline orientation.
