Research on non-isothermal Crystallization Kinetics of Poly(ethylene terephthalate)

     It has very important significance that research on the performance of poly(ethylene terephthalate) (PET) fibre, which is one of the numerous application fibre variety in industry fields. The non-isothermal crystallization process of poly(ethylene terephthalate) (PET) fibre were researched by the method of differential scanning calorimetry(DSC) and computer simulation. It was showed that the fitted error of activation energy Ed obtained from the reformed Ozawa equation and computer simulation was 0.048. And the fitted error of nucleation parameter was 0.033. The fitted error were both in confined of 10-2.The research indicates that we can obtain the activation energy Ed and nucleation parameter  of PET by computer simulation.
