Singeing and mercerization of fibers affect different properties of yarns and fabrics. This research aims to investigate their effect on the physical and chemical properties of cotton fibers and the effect of mercerization on singed yarns using a combed twisted cotton yarn, count 48/2 Ne on a singeing machine with gas and air pressure of 27 and 12 psi, respectively, to singe the yarns. After that, mercerization was performed on the singed yarns using a sodium hydroxide solution (NaOH) with a concentration of 220 g/L Baumé and a low temperature with tension. The three yarn samples were untreated, singed yarn(S), and singed-mercerized (SM), the surface morphology, hairiness, and chemical and physical structure were investigated using a scanning electron microscope (SEM), Microscopic photograph, Fourier transforms infrared spectroscopy (FTIR), and X-ray diffraction (XRD) with Gaussian fitting measurements. The results demonstrated a decrease in the percentage of yarn hairiness in singeing and mercerization, modification of the yarn surface to become more even and lustrous, and a change in the physical and chemical properties of the yarns.
