The micro- nano- sized C.I. Disperse Red 60 was prepared from the corresponding commodity disperse dye by bal mil ing, using zirconia beads as the bal mil medium and sodium lignosulphonate/polynaph?thalenesulphonate as dispersants. The effects of mil ing parameters on the particle size of the dye and its dis?persion stability were investigated. The results showed that mixed- bal mil medium with different diameters was better than that of single diameter of bal , and mixed dispersants excel ed their separate components. Un?der the conditions of the dye amount 20% in the dispersion, mass ratio of the dye/dispersant 1∶1, mass ratio of sodium lignosulphonate CBOS- 4/polynaphthalenesulphonate MF 2∶1, polyol amount 10% in the dispersion (on the mass of dye solution), mixed- bal mil medium of zirconia beads Φ=2 mm/Φ=1 mm/Φ=0.5 mm with mass ratio of 17.5∶65∶17.5, mass ratio of the dye/mil medium 1∶20, and the mil ing time 48 h, a stable dye dispersion was obtained with 132 nm of average particle size D50.
