摘　　要：将原位细乳液聚合制得的有机颜料微胶囊应用于棉织物的涂料染色,通过粒度分析、显微观察和服用性能比较,考察微胶囊化处理对于颜料颗粒聚集状态、染色织物表面形貌和染色性能的影响。在此基础上,探讨微胶囊涂料染色与传统涂料染色在成膜过程和染色效果上的区别。发现:传统涂料染色过程中颜料颗粒易发生大规模聚集,因而其织物的K/S值、耐摩擦牢度和手感很难得到兼顾。准纳米级有机颜料微胶囊具有良好的分散性和自粘性,在浸轧过程中易渗透进入纱线内部,并均匀附着于单纤维表面,进而在焙烘过程中颜料颗粒可稳定地分散于单纤维外的连续黏合剂胶膜内,因而相应的涂料染色织物具有更好的色深性、色牢度和柔软性。This thesis applies a series of organic pigment microcapsules prepared by in-situ miniemulsion polymerization to pigment dyeing of cotton fabric. In addition, it systematically studies the effects of microencapsulation of organic pigment on the dispersion state of organic pigment, surface morphology of dyed yarn and dyeing results of dyed fabric via DLS, TEM, SEM and performance tests. Besides, it builds the film formation mechanism of organic pigment microcapsule on fiber and focuses on its different with the one of conventional pigment dyeing. As a result, the authors find that it is easy to aggregate pigment parti- cles in the conventional pigment dyeing process, so the K/S value, handle, dry and wet fastness of dyed fabric are poor. Organic pigment microcapsule with quasi-nanometer size has good dispersibility and self- adhesive. Thus, the pigment with adhesive can effectively infiltrate into the inner of yarn and then evenly attach onto fiber surface in the padding process. During baking process, the adhesive can form a continu- ous adhesive film on the whole fiber surface and the pigment can disperse in the film at a stable and uniform state. Therefore, the organic pigment microcapsule dyed fabric possesses good color fastness, color depth and feel.
