Doctoral thesis covers cellulose fibre/polyester blended fabric dyeing technology elaboration using a single dye class by applying commercially available fabrics and disperse dye. The attention is focused on examination of technological factors’ influence (fabric pretreatment, content of dye bath, comparison of applied dyestuff etc.) on chemical processing. Achieved results have practical application for use of insufficiently explored textile dyestuff and its combinations in textile dyeing processes. The presented scientific approach and experimental work allow evaluating and analysing the interdependency of varied technological parameters. Doctoral thesis was elaborated at the Institute of Polymer Materials, Riga Technical University. The thesis is written in Latvian and contains introduction, three chapters, and general conclusions, bibliography of 143 titles, 150 pages of the text, 87 figures, 23 tables and 3 appendices.
