摘　　要：为解决常规分散染料染涤纶中低聚物析出、染色重现性差、费水费电等一系列问题,耐碱分散染料及相应碱性染色工艺得以关注,利用染料的耐碱性,将前处理与染色一浴进行,并通过织物K/S值、色差来表征染色效果。本文探讨了耐碱分散染料的发展与应用,阐述了分散染料碱性染色存在的问题及发展现状。耐碱分散染料及碱性染色技术的应用,不仅使得涤纶染色产品的质量获得改善,在经济、环保方面也取得了一定的效益。因此,耐碱分散染料及碱性染色技术是涤纶染色发展的新方向。In order to solve problems of conventional polyester dyeing such as precipitation of oligomers,poor dyeing reproducibility,water and electricity consumption,alkali-resistant disperse dyes and corresponding alkaline dyeing processes have been concerned.The pretreatment and the dyeing process were carried out in one bath by utilizing the alkali resistance of the dyes,and the dyeing performance was characterized by the K/S value and the color difference.The development and application of alkali-resistant disperse dyes were mainly discussed,and the problems and development of these dyes were described.The application of alkali-resistant disperse dyes and alkaline dyeing technology not just improved the quality of polyester dyed products,but also achieved certain benefits in terms of economy and environmental protection.Hence,alkali-resistant disperse dyes and alkaline dyeing technology are new development directions of polyester dyeing.
