Learning outcomes
|
The aim of theme is the deepening the knowledge of objects dedicated to the nonwovens and their production. Theme TCT focuses on expansion of theoretical and practical knowledge in the areas of nonwovens. The graduated students will be prepared for practice in the field of nonwovens for the position technologist.
Students completing the course will be able to recognize non-woven fabric. It will be educated in bonding fibers and textiles. The knowledge will be used in průsmyslovém scale as a technologist or a professional quality.
