ABSTRACT Today, the production of polymeric nanocomposite materials is one of the most important research fields. In this study, it was aimed to investigate the effect of organoclay particles on recycled polyester (rPET) fibre properties. In the literature, the studies mostly concerned with the engineering plastic applications, and hence the investigations were done on pellet and injection-moulded rPET/organoclay nanocomposite samples. Actually, fibre application is the most important market for PET wastes, but unfortunately, there are only a few papers regarding rPET/organoclay composite fibre properties. In the study, rPET/organoclay nanocomposites were prepared by melt intercalation process with different modified organoclay types (3 wt-%), and multifilament fibres were spun by the melt spinning method. Morphological and thermal properties of nanocomposites and surface structure, tensile, and thermal stability properties of the fibres were tested. The results indicated that the distribution of clay particles and organoclay types had a significant influence on various fibres properties.

再生PET（rPET）/有机粘土纳米复合纤维的各种特性

摘要如今，聚合物纳米复合材料的生产是最重要的研究领域之一。在本研究中，旨在研究有机粘土颗粒对再生聚酯 (rPET) 纤维性能的影响。在文献中，研究主要与工程塑料应用有关，因此对颗粒和注塑成型的 rPET/有机粘土纳米复合材料样品进行了研究。实际上，纤维应用是 PET 废料最重要的市场，但遗憾的是，关于 rPET/有机粘土复合纤维性能的论文很少。在该研究中，rPET/有机粘土纳米复合材料是通过熔融插层工艺与不同改性有机粘土类型（3 wt-%）制备的，并通过熔融纺丝法纺制多丝纤维。测试了纳米复合材料的形态和热性能以及纤维的表面结构、拉伸和热稳定性。结果表明，粘土颗粒的分布和有机粘土类型对各种纤维性能有显着影响。
