摘　　要：针对常规分散加工荧光颜料分散体粒径较大,稳定性较差的问题,采用细乳液聚合法制备了纳米乳胶荧光颜料,将其作为着色剂用于改性棉织物染色,探讨了纳米荧光乳胶颜料对阳离子化棉织物的染色工艺。结果表明,依据这种法制备的纳米乳胶荧光颜料的平均粒径为162 nm,Zeta电位为-34.3 m V,最大吸收波长为425 nm,最大荧光发射波长为517 nm。该着色剂对棉织物的染色性能与其阳离子化程度密切相关,在改性剂3-氯-2-羟基丙基三甲基氯化铵浓度为0.10 mol/L时,改性棉织物较佳的染色工艺:p H值为7,染色温度为50℃,染色时间为40 min,浴比1∶30,染色织物具有良好的干湿摩擦牢度。As fluorescent pigment dispersion prepared by conventional disperse process has large particle size and poor stability,nanoscale latex fluorescent pigment was prepared via miniemulsion polymerization method and applied in dyeing of modified cotton fabric. The dyeing process of cationic cotton fabrics with nanoscale latex fluorescent pigment was investigated. The results show that the particle size of the prepared nanoscale latex fluorescent pigment was 162 nm, and the obtained Zeta potential was- 34. 3 m V,the maximum adsorption wavelength was 425 nm,and the maximum fluorescence emission wavelength was 517 nm. The dyeing performance of cationic cotton fibers with nanoscale latex fluorescent pigment was closely related to the cationization degree. Results show that when the concentration of 3-chloro-2-hydroxytrimethyl ammonium chloride was 0. 10 mol / L,the optimized dyeing conditions were：p H = 7,dyeing at 50 ℃ for 40 min,and the bath ratio of 1 ∶ 30,and the dyed cotton fabrics has good rubbing fastness.
