Abstract

The effect of First heater temperature on the properties of poly (ethylene terapthalate) filaments was characterized through, I measurements of tenacity, breaking elongation, boiling shrinkage, crimp stability, crimp contraction and crystallinity. It Wits found that crystallinity reached a maximum at a temperature around 200 C, and then started to decrease. A similar behavior was observed in crimp stability. Tenacity and crimp contraction increased and boiling water shrinkage decreased, when the heater temperature increased.
