A reactive dispersant ( SMA – ESA ) was synthesised from poly(styrene‐ alt ‐maleic anhydride) ( SMA ) and 4‐(beta‐sulfatoethylsulfonyl)aniline ( ESA ), and its dispersing ability for carbon black ( CB ) was investigated. Fourier transform infrared ( FTIR ) and 1 H–nuclear magnetic resonance ( NMR ) spectroscopies showed that an amidation reaction took place between ESA and SMA . The optimal preparation conditions for reactive nanoscale CB dispersion were a mole ratio of ESA to SMA of 4:3, with a mass ratio of SMA – ESA and CB at 3%, sonication time 20 min, and pH 8. The reactive nanoscale CB dispersion prepared under optimal conditions showed excellent stability and small mean particle size. A cotton fabric coloured with reactive nanoscale CB dispersion could obtain a high K/S value, and excellent rubbing and washing fastness.
