Abstract

Poly(ethylene terephthalate)(PET) filaments of regular(monodenier 2.08d) and ultramicrofiber (monodenier 0.05d) were treated with dimethylformamide(DMF) to observe the structure change of the PET such as shrinkage, density, X-ray diffraction of the UMF treated with DMF were measured. Also, dyeing experiments were performed to see the effects of DMF. The dyeability was improved by DMF treatments, and the equilibrium dye uptake increased in spite of the increase in the density and birefringence and crystallinity. The heat shrinkage appeared in PET UMF treated PET UMF treated with DMF at $80^\circ{C}$ by TMA, DSC, and Reovibron analysis and $T_m$ peak was shown by DSC analysis.
