摘　　要：涤纶织物碱性染色可以缩短工艺过程,节能节水,是染色节能减排的重要发展方向。但碱性染色对染料的结构稳定性要求较高。用2-氨基-6-硝基苯并噻唑作为重氮组分,N-取代苯胺作为偶合组分,设计合成了5个含有不同N-取代基的分散染料。分散染料采用高温高压染色工艺对涤纶织物进行染色,研究不同NaOH质量浓度(1~5 g/L)条件下染料的上染性能,以及在碱性染色条件下染料结构与染色稳定性的关系;对比不同结构的染料在酸性、碱性条件下的染色性能。结果表明,含有乙基和苄基结构的杂环染料具有良好的耐碱稳定性,染色条件的酸碱性对两个染料的上染速率无明显影响,且染色牢度优良。Alkaline dyeing of polyester fabric can shorten the traditional dyeing process,save energy and water.It is an important direction of energy conservation and emission reduction.But alkaline dyeing has a higher requirement on the structural stability of dyes.With 2-amino-6-nitrobenzothiazole as diazo component and N-substituted aniline as coupling component,five disperse dyes containing different N-substituents are designed and synthesized.The dyeing properties of polyester fabric with disperse dyes under different NaOH concentrations(1~5 g/L)are tested.The relationship between dye structure and dyeing stability under basic dyeing conditions is discussed.The dyeing properties of dyes with different structures under acid and alkali conditions are compared.The results show that the hybrid dyes with ethyl and benzyl structure has good alkali resistance stability,acid and alkali dyeing condition have no obvious influence on the dyeing rate of the two dyes,and the dyeing fastness is good.
