Abstract The classification of textile dyes has become essential due to the remarkable increase in the type and number of dyes. The structural classification of these dyes can be determined by the following functional groups: Anthraquinone, azo, phthalocyanine, sulfur, indigo, nitro, nitroso, etc. taking into account their chemical structures. Another classification was based on the method of applying these dyes on an industrial scale. The dyes are grouped together as dispersed, direct, acid, reactive, basic, vat, etc. In this review, the dyes will be studied in three different groups depending on the chemical structures with an overview on the synthesis of some new dyes, color index numbers (C.I.) and application methods. Finally, it would be also interesting to briefly discuss the effects of the textiles dyes on environment.

纺织染料分类、近期合成及应用综述

摘要 随着染料种类和数量的显着增加，纺织染料的分类变得至关重要。考虑到它们的化学结构，这些染料的结构分类可以由以下官能团确定：蒽醌、偶氮、酞菁、硫、靛蓝、硝基、亚硝基等。另一种分类是基于在工业规模上应用这些染料的方法。染料分为分散染料、直接染料、酸性染料、活性染料、碱性染料、还原染料等。在这篇综述中，染料将根据化学结构分为三个不同的组进行研究，并概述一些新染料的合成、颜色索引号 (CI) 和应用方法。最后，简要讨论纺织品染料对环境的影响也很有趣。
