Paper Title:
Microstructure and Property Changes of Poly ( Ethylene Terephthalate) Fiber with Moderate Tenacity during Heat Treatment under Constant-Length Conditions
  Abstract

In this paper, Wide Angle X-ray Diffraction (WAXD), Small Angle X-ray Scattering (SAXS), Dynamic Mechanical Analysis (DMA) and mechanical testing were employed to characterize the effect of heat treatment under constrained condition on poly(ethylene terephthalate) (PET) fiber. The microstructure and property of the PET fiber with moderate tenacity changed with the heat treatment temperature from 110 °C to 190 °C. No change happened in the crystalline phase while the micro-crystal formed in the amorphous phase from the result of crystalline parameters, which led to the increase of Tg of the fiber. The decrease of the tenacity is due to the decrease of the amorphous orientation and the decrease of the long period leads to the increase of the stability of the fiber.
