摘要：

In the present work the structural development of freshly moulded poly (ethylene terephthalate) fibers with different preliminary orientation subjected to simultaneously thermal and mechanical treatments was studied. Uniaxially strain-loading experiments are conducted with partially crystalline PET yarns in a narrow temperature range from 80 degrees C to 95 degrees C and strain stress values of 40 MPa, 80 MPa, and 120 MPa. Differential scanning calorimetry and birefringence measurements were used to investigate the effects of the preliminary orientation, annealing temperatures and strain stress on the structure development of the studied samples. There are established relationships between the fibres preorientation, experimental parameters and the structural rearrangements running in the investigated yarns.
