Surface activation of polyester fabric using remote plasma: Dyeability with disperse dye properties

Abstract

The effect of oxygen plasma activation of polyester fabric surface on the dyeability with a dispersed dye was     investigated. A scanning electron microscope (SEM) was used to examine changes in fiber surface morphology, and an infrared spectrometer (FTIR) was used to analyze alterations in its chemical composition. Furthermore, the impact of the treatment on the fabric’s tearing strength was evaluated. The treated samples were dyed with a dispersed dyed at 100°C and atmospheric pressure, and another untreated sample was dyed in the conventional way using an autoclave device at high temperature and pressure (125°C, 0.165 MPa). The color strength of the dyed samples was analyzed using a spectrophotometer. Subsequently, the samples were subjected to a washing-fastness test for both treated and untreated samples. The results revealed that the treated samples had higher color strength and better washing fastness than the untreated samples.
