Learning outcomes
The course "Chemistry for Textile" unifies and improves the basic knowledge of chemistry to understand the principles of production and maintenance of textiles. It is an essential subject for understanding the technology of textile finishing, which is subsequently teach as course "Finishing". "Chemistry for Textile" presents chemical bases on textile examples. In accordance with the requirements on the knowledge of textile experts, the subject is largely focused on technological water, surfactants, dyes, polymers, sorption and transport processes.
Knowledge lectured subject - theoretically and practically.
Basic knowledge of chemistry.

Assessment methods and criteria
Oral exam

The credit: Finishing on all laboratory exercises. Elaborate and defence laboratory records. Finishing on knowledge test The examination: written
