| Abstract: | The improvement in the properties of blended fibres prepared from poly(ethylene terephthalate) and 0-10% poly(butylene terephthalate) during annealing is influenced by chain entanglement and extent of phase segregation. The structural properties like crystallinity, birefringence and amorphous orientation of 98/2 PET/PBT blend fibre show minimum change due to chain entanglement resulting in better mechanical properties, 94/6 PET/PBT fibre shows maximum change in structural properties owing to phase segregation during annealing. The mechanical properties of 92/8 PET/PBT blend fibres deteriorate after annealing as a result of two-phase structure leading to higher incompatibility. |
