The cationic modified cotton fabrics were directly dyed with carbon black (CB) nanoparticles aqueous dispersions through exhaustion process . The effects of CB concentration, CB nanoparticles size, dyeing bath pH, dyeing time and temperature have been investigated. The color yield of dyed fabrics which is characterized by Kubelka-Munk value K/S was studied. The surface morphologies of cationic modified and non-modified cotton fabrics were measured by the DZ3-video focus-exchanged microscope. The results showed that the fabrics present good color yield, dyed at 80?, for 30 min with pH 13 using a 50:1 liquor ratio, and the dyeing solution contained 2% o.w.f. CB. The images showed a clear surface profile for the cationic modified cotton fabrics dyed with smaller CB particle size solutions. So CB nanoparticles are suitable for dyeing the cotton fabrics black.
