| Popis: | The range of active dyes used for dyeing materials made of natural plant fibers includes about a thousand brands belonging to more than 50 groups all over the world. Among them, bifunctional active dyes are of research and practical interest. They allow to obtain intense and durable bright color scheme due to their chemical specificity. Also they save not only the dye itself, but a number of additional textile auxiliary substances, which in turn is favorably affects the environmental performance of the dyeing process. The authors present in the article the analysis of experimental data, which make it possible to obtain or verify chemical, physicochemical and coloristic indicators of the properties of mono-, bi- and polyfunctional active dyes. Conclusions are made on the dependence of these indicators in the process of dyeing textile materials according to several technologies most often used in finishing production. |
