PET Blend with PBS Fiber: Manufacturing, Properties, and Dyeability

In this paper, polyethylene terephthalate (PET) fibers were blended with a biodegradable polymer, poly (butylene succinate) (PBS) was investigated in this study. The melt-spinning process produced PET/PBS fibers at the different PBS contents in the PET matrix. We evaluate the effectiveness of the dyeability of PBS contents in PET fibers. The yellow organic dye (Turmeric extract) was used as a coloring agent. The spectrophotometer results show that the dye absorption of the fiber increased with PBS contents. The SEM images confirm the relationship between the dye coating on the fiber and PBS contents in the PET matrix. This indicates that the PBS can act as a compatibilizer or modifier to improve dye penetration and fixation in PET/PBS fibers.
