Effects of Crystallization on the Glass–Rubber Transition in Polyethylene Terephthalate Filaments

Abstract

MULTIFILAMENT yarn spun from polyethylene terephthalate polymer (‘Terylene’ polyester yarn) is non-crystalline and almost unoriented. After drawing, it becomes highly oriented and moderately well crystallized1, and in this state at room temperature it has a high initial tensile modulus, and recovers almost completely from strains of up to 1 per cent2.
