Effect of Thermal Stimuli on Physical Behaviors of PET/PTT Bicomponent Filament

Abstract

PET/PTT bicomponent filament composed of PTT and PET arranged side-by-side often manifest high curliness after being thermally stimulated at different temperature. In this article, we report an investigation of the effect of thermal stimuli on the performances of PET/PTT bicomponent filament under various temperatures. Both the original and the thermally stimulated ones were characterized by mechanical, thermal, thermo-mechanical and optical methods. The changes of other relevant properties were also discussed.
