Acrylic fabrics have been treated with sulphuric, hydrochloric and phosphoric acids and the treated fabrics dyed with a cationic dye at 80°C for various times. The pretreatments were found to improve dyeability with this type of dye, and the fastness properties were also improved. The effect on nitrogen and carboxylic content, moisture regain, shrinkage, tensile strength and elongation have also been studied. Infrared spectra have been used to suggest the structural changes in the treated acrylic fabric.
