ABSTRACT

In this study, poly(ethylene terephthalate)(PET) fibres dyed with Disperse Red 167 using supercritical CO2 Technology. The purpose of this study was to investigate relationship between PET fibers and Supercritical CO2 during dyeing. The effects of temperature, pressure, dyeing time and mass ratio between the dye and PET in the dyeing chamber were considered. Thermal and mechanical properties of the fibers were investigated. Tensile strength of dyed PET fibers decreased at higher temperature and pressure conditions. DSC and DMA results indicated that the Tg and Tm values decreased significantly when compared to the pure PET fibers. However, uniformly dyed PET fibers were typically observed.
