Abstract:

In order to improve mechanical properties of easy cationic dye-modified polyester(ECDP) fiber, a method for improving the intrinsic viscosity of the slices was proposed. ECDP slices prepared by melt polycondensation as raw material were tackified by solid-phase polycondensation to obtain tackified slices. Ubbelohde viscometer, differential scanning calorimeter, X-ray diffractometer, fluorescence spectrometer, and thermogravimetric analyzer were employed to investigate the properties of ECDP slices. The results show that the optimum solid phase tackifying process conditions for ECDP slices are temperature of 190 ℃ and time of 9 h. The intrinsic viscosity of ECDP slices increases with the reaction temperature or reaction time, and the intrinsic viscosity is linear with the square root of time. The intrinsic viscosity of the slices tackified at 190 ℃ for 9 h is 0.69 dL/g. Under the conditions of higher than the reaction temperature or longer than the time, the surface of ECDP starts to become yellow due to thermal degradation.

Key words: easy cationic dye-modified polyester, solid-phase polycondensation, intrinsic viscosity, thermal degradation property
