Melting And Crystallization

Poly (ethylene terephthalate)/poly (trimethylene terephthalate) (PET/PTT) blends were prepared and their melting and crystallization properties were investigated by differential scanning calorimetry (DSC). The glass transition temperatures suggest apparently that PET and PTT have good miscibility at amorphous state. The blends with more PET content less likely undergo a melting/recrystallization process during DSC heating scan. In the blends, PET component with higher supercooling degree will crystallize first, and then the crystallites of PET will be the nucleating agents for PTT, which greatly improves the crystallization rate of PTT.

Abstract The effect of changes in the surface structure of glossy polyester filaments from poly(ethylene terephthalate) in terms of its micro-topography, molecular and supermolecular structure of the fibre surface layers on selected fibre surface and volumetric properties has been assessed. The performed tests and measurements have shown that the change in the general surface characteristics of PET fibres (micro-topography and hydrophilicity) results in very beneficial changes in both their volumetric (dyeability) and surface properties (wettability, pilling, oil-soil removal and electric properties).
