| Learning outcomes |
|
The course provides general introduction to the textile chemistry. There is increasing emphasis on the chemistry of inorganic and organic compounds used in the textile industry, their production, properties and applications. The course give a theoretical approach to the application of dyestuffs, detergents, polymers and textile auxiliaries to fabrics.
