Five different poly (ethylene terephthalate) (PET) materials (two recycled and three virgin ones) were melt-spun into fibers using a capillary rheometer and aerodynamic stretching. Two processing temperatures in combination with six different take-up pressures were used during the melt spinning process. The spinnability (evaluated by the homogeneity and drawability), and surface morphology smoothness of fibers, and the mechanical properties of fibers were investigated. As a result, rPET-B (rPET means recycled PET) and vPET- 1 (vPET means virgin PET) were evaluated as the most suitable material for melt spinning from the recycled and virgin PET, respectively. Compared with other research, the melt-spun PET fibers in this study achieved satisfactory tenacity, outstanding elongation at break and a desirable denier. Additionally, the performance and reliability of the PET fibers from rPET-B and vPET-1 were discussed using Weibull modulus as shown in Figure 1.
Y Qin has completed her Master’s Degree from School of Materials Science and Engineering in Zhengzhou University in 2016. During this period, she mainly focused on the development of crystalline morphology and crystal modification evolution of isotactic polypropylene (iPP) under shear flow field, especially the formation mechanism of the shear-induced β-iPP crystals. At present, she has been pursuing her PhD Degree at the Institute of Polymer Materials of Friedrich-Alexander-University Erlangen-Nuremberg. The research field is to investigate the recycled PET in fiber spinning and rheology, to make an evaluation of potential recovery routes. She has published more than 12 papers in reputed journals.
