摘要：通过乳液聚合法制备了以 C.I.分散紫 93 为核、甲基丙烯酸甲酯（MMA）-丙烯酸丁酯（BA）共聚物（聚
丙烯酸酯）为壳的纳米分散染料胶囊（NDDM），采用 TEM、SEM、FTIR、TG 对 NDDM 进行了表征，探究了
核壳质量比、MMA/BA 质量比、固色温度和固色时间对涤纶织物轧染染色性能的影响。结果表明，NDDM 对
涤纶织物轧染染色的色牢度和匀染性均优于 C.I.分散紫 93 染色织物。当核壳质量比为 1∶2、MMA 和 BA 质量
比为 1∶1、焙烘温度 180 ℃、焙烘时间 5 min 时，NDDM 轧染染色织物的颜色深，手感变化小，且未水洗染色
织物的各项色牢度均达到 4 级及以上，还原清洗化学需氧量为 312.3 mg/L，比 C.I.分散紫 93 还原清洗化学需氧
量下降了 58%。在高温下，NDDM 内分散染料从聚丙烯酸酯壳层内迁移释放并上染纤维，聚丙烯酸酯壳将未进
入纤维内的残余染料覆盖固着在纤维表面。

Abstract: Nanoscale disperse dye microcapsules (NDDM) with C.I. disperse violet 93 as core and
copolymer of methyl methacrylate (MMA) and butyl acrylate (BA) (polyacrylate) as shell were prepared by
emulsion polymerization method, and then characterized by TEM, SEM, FTIR and TG. Furthermore, the
effects of core-shell mass ratio, MMA and BA mass ratio, curing temperature and curing time on the
pad-dyeing properties of polyester fabric were investigated. The results showed that the color fastness and
levelness of NDDM pad-dyed fabric were better than those of C.I. disperse violet 93 pad-dyed fabric. When
the core-shell mass ratio was 1∶2, MMA/BA mass ratio was 1∶1, curing temperature was 180 ℃, and
curing time was 5 min, NDDM pad-dyed fabric exhibited deep color, little change of feel, and the color
fastness of unwashed dyed fabrics reached grade 4 and above. Moreover, the chemical oxygen demand
(COD) of reduction cleaning was 312.3 mg/L, a reduction of 58% compared with that of C.I. disperse violet
93 dyeing. The better performance could be attributed to the mechanism that, disperse dye in NDDM
migrated out of polyacrylate shell and dyed polyester, and the polyacrylate shell covered and binded the
residual dye on the surface of polyester fabric at high temperature.
