摘　　要：采用阳离子型分散剂SMD与颜料永固红F5RK,按1∶6配制颜料分散液,通过微射流粉碎机高压高剪切作用制备阳离子型超细颜料分散体系,并应用于棉针织物浸染工艺。试验结果表明,阳离子超细颜料具有良好的分散稳定性,分散液粒径可细达217.7nm,Zeta电位为38.4mV,在使用、储存和高温下均不发生分层、沉淀等变质现象。在颜料用量3.5%(owf),浴比1∶50,温度80℃,时间160min的染色条件下,棉织物的上染率为97.94%,K/S值为14.909,干、湿摩擦牢度分别为2～3级和1～2级。The cationic ultra-fine pigment dispersion system was prepared by cationic dispersant （SMD） and the pigment red F5RK with 1 ：6, and was applied to dip dyeing of cotton knitted fabric. The results indicate that, the particle size of the cationic ultra-fine pigment dispersion system is 217.7 nm, the Zeta potential is 38.4 mV. The dispersion has good dispersion stability under high temperature, use and storage. The dye-uptake of cotton fabric can reach 97.94 %, K/S value is 14.909, dry rubbing fastness is 2 - 3, wet rubbing fastness is 1 - 2, under the condition of pigment concentration 3.5 % （owf）, bath ratio 1 ： 50, and dyeing at 80℃ for 160 minutes.
