Вивчено та описано термодинаміку процесу фарбування поліефірних текстильних матеріалів
дисперсними барвниками в присутності аніліду саліцилової кислоти, проведено аналіз кінетичних кривих сорбцій,
досліджено вплив інтенсифікаторів на дифузію дисперсних барвників в поліетилентерефталатний субстрат.
Встановлено, що коефіцієнти дифузії збільшуються практично на порядок для усіх марок дисперсних барвників,
зростає спорідненість барвників до поліефірного волокна і збільшується вибирання дисперсних барвників до 85 %.
For the successful development of the textile and light industry it is necessary to expand and qualitatively improve the raw material base due to the widespread use of chemical fibers. At the same time, special attention is paid to increasing the production of polyester fibers. The growing role of these fibers in the raw material balance of wool, silk, knitwear industries is primarily due to their valuable properties: high dimensional stability, compatibility with all types of natural and hydrated cellulose fibers, good strength, light and heat resistance. However, during their coloring there are significant difficulties associated with the peculiarities of their structure: high order of polyethylene terephthalate fibers, packing density of their macromolecules, hydrophobic nature of the fiber, lack of groups capable of interacting with ionic dyes, heterogeneity of textile yarn . The work contains results of a complex investigation how properties and structure of polyester textiles colored with dispersed dyestuffs are changed at the presence of an intensificator – salicylic acid anylide. The obtained results are used to determine the mechanism of the intensificator’s action during coloration. New technological modes were proposed for intensification of coloration process. These mode enable to eliminate the primary stage of textile processing – removal of grease and dirt by means of introduction of a stable composition of salicylic acid anylide and a mixture of surface active substances to a dye bath. The investigation of the effect intensifier on the sorption of dispersed dyes.
