摘　　要：综述了近年低温染色、少水及无水染色、原液着色和结构生色等聚对苯二甲酸乙二醇酯(PET)纤维染色和着色技术的研究现状和产业化进程。低温染色可以通过载体染色或对PET进行共聚改性实现,高效、绿色载体的开发是促进载体染色发展的关键,而工业生产不稳定是共聚改性PET纤维目前亟需解决的主要问题。水少及无水染色主要包括超临界二氧化碳染色、十甲基环五硅氧烷染色和有机溶剂染色等,在尽可能安全、简便的工艺操作流程下实现高效上染是该染色技术实施推广的前提。原液着色可以通过原位聚合法或色母粒添加法直接制得有色PET纤维,着色剂的超细化和分散技术是提升原液着色纤维品质的关键。光子晶体结构生色和薄膜干涉结构生色是目前制备结构色PET纤维的常用手段,大幅提升结构色牢度和制备效率是当前最需攻克的技术难点。The research and industrialization progress in dyeing and coloring technologies for polyethylene terephthalate(PET) fiber were reviewed in the latest years, including low-temperature dyeing, less water and water-free dyeing, dope dyeing and structural coloration. Low-temperature dyeing can be realized by carrier dyeing or copolymerization modification of PET, and the key to the development of carrier dyeing technology is to develop efficient green carriers while unstable industrial production is the main problem for copolymerization modified PET fiber to be solved urgently. Less water or water-free dyeing technology mainly includes supercritical carbon dioxide dyeing, decamethylcyclopentasiloxane dyeing and organic solvent dyeing, and the premise of the popularization of this dyeing technology is to realize efficient dyeing under safe and simple operation process as far as possible. Dope dyeing technology is to directly prepare colored PET fiber by in-situ polymerization or color masterbatch addition, and the key to improve the quality of dope-dyed fiber is the super refinement and dispersion technology of colorants. The common methods to prepare structurally colored PET fibers include photonic crystal structural coloration and film interference structural coloration, and the technical difficulty that needs to be overcome at present is to greatly improve the structural color fastness and preparation efficiency.
