摘　　要：针对分散染料染涤纶过程中易析出低聚物导致染色重现性差、染色成本增加等问题,提出采用碱性染色技术对涤纶进行染色。介绍了近年来涤纶碱性染色技术的发展状况和存在的问题,指出引入不易水解的基团或引入空间位阻较大的取代基是未来耐碱型分散染料的研发方向。Aiming at the problems of poor dyeing reproducibility and increased dyeing cost caused by the precipi⁃tation of oligomers during the traditional disperse dyeing of polyester,alkaline dyeing technology is proposed.The development status and existing problems of alkaline dyeing technology for polyester in recent years are in⁃troduced,and it is pointed out that introducing of non hydrolyzable groups or substituents with high steric hin⁃drance is the future research and development direction of alkali-resistant disperse dyes.

关 键 词：碱性染色 耐碱型分散染料 涤纶 清洁生产
