共聚芳酯/聚酯共混纤维热性能的研究(英)

Investigation on the thermal behaviors of polyarylate/polyester blend fibers

本文利用DSC热分析技术，对共聚芳酯／聚酯（PHET）共混纤维的热性能进行了研究．结果表明，在热处理过程中，共混纤维中两种组分的结品行为相互独立，而熔融行为则相互影响．虽然P（HBA／HNA）三维有序程度远不如PET，但在共混纤维中其规整度有所改善．

Thermal behaviors of polyarylate/polyester blend fibers (PHET blend fiber)are investigated by means of the DSC thermal analysis. The results show that the behaviors of crystallizationabout the two components in the PHET fibers, P(HBA/HNA)and PET, are independent of each otherduring an annealing treatment, that is, no inhibition between the two components occurs, the behaviors are different from that of crystal melting. The degree of three-dimensional order of P (HBA/HNA) is far from as good as that of PET, and the structural regularity of P (HBA/HNA) are improved to a certain extent in the PHET blend fibers.
