Characterization of Dyeing P/C Blends Fabric: a Thermodynamic View

The dyeing of the polyester and cotton blend fabric (P/C fabric or PCF) has becomes a challenge to the modern textile industries due to its variation in color value, shed depth, tensile strength and surface residual weight loss. All of this drawback can be control by the proper selection of the dye-fiber combination which ultimately governs the XRD, SEM, FTIR analysis of the dyed blend fabric. The water fastness or wash fastness and light fastness can be also improved by the proper analysis of the thermodynamic equilibrium of dye fiber bond and its stoichiometry.
