Outline of Final Research Achievements |
Crystallization rate of oriented poly(ethylene terephthalate) (PET) was investigated using high-speed DSC analysis. Quantitative analysis method was established by applying pre-thermal treatment to remove thermal shrinkage. There was a difference between uni-axially oriented fibers and equi-biaxially oriented films on the Avrami index and the trend of crystallization rate to crystallization temperature. In addition, uni-axialli orientation had greater effect on crystallization rate than qui-biaxially orientation in same degree of orientation if that of equi-biaxially oriented film was calculated based on intrinsic birefringence of planner orientation, 0.122.
