Thermotropic liquid crystalline polymer (TLCP) / poly(ethylene 2,6-naphthalate) (PEN) / poly(ethylene terephthalate) (PET) ternary blends were prepared by melt blending, and were melt spun to fibers to improve fiber performance and processability. The mechanical properties of ternary blend fibers could be significantly improved by annealing. This result was attributed to the development of more ordered crystal structures and the formation of more perfect crystallites. Multiple melting behaviors observed in the annealed ternary blend fibers depended on annealing temperature and time, which were caused by the different lamellae thickness distribution.
