The mechanism of thermally induced elongation in poly(ethylene terephthalate) fiber spun at 3500 m min 01 has been examined. This partially oriented fiber has a crystalline content of about 25% and a high degree of orientation. The effect of time and tension during heat treatment was examined, and i
WAXS, DSC, and IR methods have been employed to follow the crystallization of poly(ethy1ene terephthalate) as a function of molecular weight. The degree of order, which is a measure of the extent of crystallization, decreased with increasing molecular weight. The degree of reduction in the molecular
