초록

The mechanical properties and dyeability of Poly(trimethylene terephthalate)(PTT) were investigated and compared to PET. Glass transition temperature of PTT was lower than that of PET, because amorphous region of PTT is mote flexible. n has smaller molecular and specific stress and larger strain than those of PET, due to the difference of molecular structure. Dyeing transition temperature of PTT was lower by $20^\circ{C}$ than that of PET. Because PTT has flexible chain and zigzag structure, dyeing Fate of PTT is faster than PET and dyeing of PTT is begun at lower temperature. As the hydrophobicity of disperse dyes increased, the ratio of equilibrium dye uptake on PTT to that on PET was increased.
