Short course description
Content of the short-term learning experience
Definition of dyeing processes during the production of textiles from synthetic polymers. Innovations in the field of textile auxiliaries, chemicals and dyes and criteria for their selection from a quality, ecological and economic point of view. Dyeing medium - technological water, alternative media and the use of modern procedures based on environmentally friendly technologies. Phases of work, preparation of recipes and apparatus/machines for dyeing. Technological implementation of the dyeing process of various synthetic materials with emphasis on PA, PES and PAN fibres using the appropriate machinery, and the impact of an individual chemical, textile auxiliary and dye on quality and environmental parameters.
Definition of quality characteristics of the dyeing process, CIELAB numerical evaluation of colours, determination of dye concentration in the bath and on the material, and evaluation of pollution parameters of textile wastewaters.

prof. dr. Darinka Fakin
Dr. Darinka Fakin is a full professor in the field of Materials at the Faculty of Mechanical Engineering, at the University of Maribor. Her research activities are mainly focused on textile chemical processes in the field of functionalization of materials; she also deals a lot with environmental issues, especially in the area of technological wastewater treatment. She is also involved in the development of dyeing processes and the study of dyeing kinetics. A special part of her research is dyes and colours, both from an environmental, physical-chemical and psychological point of view.
Her work is also aimed at the development of biotechnological processes, studying the mechanisms of action of multi-enzyme systems depending on the type and activity of enzymes. This is also related to the introduction of new techniques and the study of the influence of ultrasound in inhomogeneous systems, where she actively cooperated with partners in international projects.
As part of her research work, dr. Darinka Fakin also collaborates with many industrial partners, she is the head of the Laboratory for Dyeing, Colourimetry and Finishing Ecology, and the Centre for Dyeing and Colours, and she participates in many bodies at the Faculty.

Assist. prof. dr. Alenka Ojstršek
Dr. Alenka Ojstršek is an assistant professor in the field of Materials and a research associate at the Faculty of Mechanical Engineering, Department of Textile Materials and Design, University of Maribor, where she participates (has participated) in several national and EU fundamental and applied projects, teaches Erasmus students in the field of finishing technologies and is a mentor to young researchers and co-mentor to several masters and diploma students in the field of dyeing, colourimetry and treatment of coloured wastewater. She has expertise in the field of surface functionalization of textile materials, environmentally friendly pretreatment, dyeing and finishing of textiles, surface characterization, determination of mechanical properties of composites, colourimetry, and development of innovative technologies/procedures for processing (non)fibrous materials. She also performs colour measurements in the UV/VIS/NIR range for various industrial partners. She has obtained funding as part of the Slovenian national funding ARIS, project J2-50087 (2023-2026). In 2021, she successfully completed the Horizon 2020 MATUROLIFE project, as a leader at the University of Maribor (partner in a project) and a WP leader in this project.
