Course Objective

To inform students about natural dyes, sustainable extraction and dyeing methods, mordant applications, ecological methods for improving dyeability, to introduce appropriate test methods that can be used in the evaluation of extraction and dyeing efficiency, and to provide the ability to follow and evaluate current academic studies.

Learning Outcomes of the Course Unit

1   Gain knowledge about natural dyes and their differences from synthetic dyes.
2   Gain ability to detect natural sources for coloration and functionalization of textiles.
3   Gain knowledge about extraction, mordanting and dyeing processes.
4   Gain knowledge on conventional and novel natural dyes and application methods.
5   Evaluate the current scientific developments on natural dyeing and sustainability.
