THE COURSE CONTENT

Properties and behavior of individual components of detergents as well as their interaction, synergism before application, during and after application. Surfactants in detergents, their action and biodegradability. Staining mechanisms, selection of stain removal agents and risks of poor selection. Solvents for dry cleaning, solubilization and alternative solvents. Toxicological and ecological studies of textile care products according to existing legislation. Determination of primary and secondary effects in textile care. Hygienic aspect in textile care. The influence of residual care products on textiles on the skin during wear. Seminar papers on current issues in cooperation with graduate students.

OUTCOMES

The student will be able to:
● explain the mechanisms of attachment and removal of stains from textiles depending on the technical characteristics of the textile and the composition of the washing bath
● explain the primary effect in washing depending on process parameters (hydrodynamic effect)
● connect the effect in washing with the process of wetting, adsorption, emulsification, dispersion, solubilization
● apply acquired knowledge in quality control of the washing process
● analyze the critical control points of the process
● develop methods in quality control of the washing process
● to design favorable technological and sustainable textile care processes
● analyze and improve textile care processes

THE AIM

The acquired knowledge will enable the student to monitor and optimize the influence of the ingredients of individual formulations considering a technological and eco-toxicological point of view. Students will learn the mechanisms and interactions of anionic and nonionic surfactants, builders, enzymes, bleaching agents, bleaching activators, antiredeposition agents, and other ingredients in detergents. Students will understand the meaning of physico-chemical phenomena in the removal of fat, pigment and other stains on textiles. By analyzing the influence of individual components on the properties and deformations of textiles in care, they will acquire more permanent knowledge. They will learn about washing quality control systems, including technological parameters and hygiene. Students will learn about possible skin irritations due to residual components onto textiles after washing process. Students will adopt modern processes for the production of powder and liquid detergents, as well as modern procedures for professional care of textiles. By creating seminar papers, students will learn about current problems and novelties in the field of textile care.
