摘　　要：对配伍性能极不匹配的纯分散染料进行微胶囊化,改变壁材种类和芯壁比调节微胶囊对分散染料的释放速率,可基本实现非助剂增溶的分散染料微胶囊超细涤纶织物非条件配色。通过测定上染曲线、提升力曲线、K/S值、明暗度L值、红绿轴a值、黄蓝轴b值、色相角H值等相关染色参数考察分散染料的配伍性能,并比较相应染色样品的水洗牢度、摩擦牢度、匀染性。结果表明,常规条件下不能配色的分散染料其配伍性可在非助剂增溶条件下通过微胶囊化加以改善,并可获得与助剂增溶条件下染色样品相当的色牢度,匀染性接近5级。Unconditioned color combination based on auxiliary-free solubilization can be carried out on pure disperse dyes with poor compatibility by varying preparation conditions of microencapsulation.Uptake curve,build-up curve,K /S value,brightness L value,a value（red and green axis）,b value（yellow and blue axis）,H value（hue angle） and related properties of dyed samples,such as washing fastness,rubbing fastness and levelness,were studied respectively.The results show that compatibility of disperse dyes are significantly improved by microencapsulation.The fastnesses of ultra-fine PET dyed with microencapsulated disperse dyes are as good as that of the samples dyed with auxiliary solubilization disperse dyes.The levelness reaches about 5 grade.
