Learning outcomes
The aim of the course "Fiber Engineering" is to acquaint students with the fibre structures, their properties and their real use. The course is unique in its view of fibre structures as a simple system in which we change the final properties by targeted changes of inputs. Understanding of these connections (supported by the logical structure of this course) broadens students' knowledge of the general behaviour of materials and especially textiles.
Theoretical and practical knowledge dealing with content of lectures and excercises
