摘　　要：分散染料可以分子状态溶于溶剂中,将含有染料单体的溶液进行微乳化,乳液形成的胶束可以达到纳米级别,形成液状纳米分散染料微乳。采用半连续预乳化种子微乳液聚合法,制备三种微乳液状纳米分散染料。对制备的微乳液状纳米分散染料进行表征,并研究了微乳液状纳米分散染料微乳液粒径、Zeta电位、粘度、表面张力、粒子形貌、体系流变性及染色印花性能。结果表明,三种微乳液状纳米分散染料微乳液的胶粒粒径均在50~150 nm,固体胶粒粒径在50~70 nm,Zeta电位在-50 m V左右、表面张力在45 m N/m左右、粘度在2.5m Pa·s左右,体系接近牛顿流体。在SEM图中,微乳液粒子均为规则的球形,微乳液对涤纶有较高的上染率及印花转移率。Disperse dye is able to be dissolved in monomer solvent as molecular state and then the solution containing dye is microemulsified. A nanoscale micelle can be obtained with microemulsification, which forms liquid nano disperse dye microemulsion. Three kinds of microemulsion nano disperse dye are prepared with semi-continuous pre-emulsifica- tion seed microemulsion polymerization. The prepared microemulsion nano disperse dye is characterized. The particle size, Zeta potential, viscosity, surface tension, morphology, system rheology, and dyeing and printing performance of microemulsion nano disperse dye are investigated. The results show the diameters of three kinds of microemulsion nano disperse dye micelle is within 50~150 nm, the size of solid micelle is 50~70 nm, Zeta potential is about -50 mV, surface tension is approximately 45 mN/m, viscosity is around 2.5 mPa.s, the system is closed to Newtonian fluid. Microemul- sion particles are regular spheres in SEM images. The microemulsion presents good dye uptake and printing transfer rate on polyester fabrics.
